Sleep and CVD: What Can Midlife Women Do?

Ren Jones/1 July 2024/ All MFN blog/

It was the scorching summer of ’96 when I received a call that rocked my world—my 60 year old mother had suffered a stroke. This powerful woman’s life changed forever. Years later, my brother, a firefighter whose sleep was frequently interrupted by alarms, tragically lost his life to a heart attack. These personal stories illustrate the profound effects of sleep on heart health, particularly for midlife women.

The Hard-Hitting Stats: Focused on Midlife Women

Let’s dive into the statistics that underscore the importance of this issue specifically for midlife women:

Stroke Alert: 20% of midlife women will encounter a stroke by the age of 55. This statistic is drawn from the National Stroke Association, highlighting the elevated risk for this demographic.
Death by Stroke: Women account for 57% of stroke deaths, a significant gender disparity in stroke mortality rates reported by the American Heart Association.
Race and Risk: Black midlife women face disproportionately higher mortality rates from strokes, pointing to an urgent need for targeted health interventions, as noted by the National Institutes of Health.
Heart Disease Dominance: Over 60 million women, many in their middle years, live with heart disease, the leading cause of death for women, outpacing all cancers combined. These figures are supported by data from the Centers for Disease Control and Prevention (CDC).

Research Revelations: The SWAN Study by Rebecca Thurston, PhD

Dr. Rebecca Thurston’s research utilized the Study of Women’s Health Across the Nation (SWAN), a multi-decade study initiated in 1996. Focusing on 2,517 women whose sleep patterns were monitored through midlife for 22 years, the study involved 16 different interviews where participants self-reported their sleep habits. Here’s what they found:

Long-term Insomnia Risks: Women with persistent insomnia throughout midlife have a 70% increased risk of developing cardiovascular diseases, revealing the critical impact of sleep quality on heart health.
Impact of Sleep Quality: Those with persistent insomnia and short sleep exhibited a 75% increased risk of cardiovascular issues, emphasizing the importance of both sleep quantity and quality.

What Can Midlife Women Do?

So, what actionable steps can midlife women take to mitigate these risks? Here are some effective strategies:

CBT-I for Better Sleep: Cognitive Behavioral Therapy for Insomnia (CBT-I) helps develop healthy, drug-free sleep patterns and is endorsed by numerous sleep studies and health organizations as an effective treatment for insomnia.
CPAP for Sleep Apnea: For those disrupted by sleep apnea, using a CPAP machine can significantly improve sleep quality.
Lifestyle Tweaks: Engaging in morning exercises and avoiding blue light exposure from electronic devices in the evenings can greatly enhance sleep quality and overall heart health.

This isn’t just about discussing sleep; it’s about taking actionable steps to improve heart health for midlife women. By transforming personal loss into proactive health strategies, we aim to advance this conversation together and ensure every moment is lived to its fullest.

Can Sleeping Less Equal Weight Gain?

Mirabai Holland, MFA, EP-C, CHC/16 October 2023/ All MFN blog/

Eating fewer calories, exercising more and still having a hard time getting those extra pounds off? Here’s a question for you: How’s your sleep?

I for one, every time I travel, seem to gain a couple of pounds just when I want to look my best.

I noticed that I tend to sleep less and intermittently when I am on the road. Once I settle again in a place, my sleep gets more regulated and I am able to drop those pounds.

I’ve adjusted my sleep pattern, as I have gotten older to help myself sleep better. The earlier I get up in the morning the better chance I have of getting to sleep that night and staying asleep for a longer period of time. I’m more energized, and when I eat, I eat less and feel more filled.

Can Sleeping Less Equal Weight Gain?

It turns out that there are many studies that indicate that sleeping less then 7 hours can increase body weight. One recent study with several pairs of twins, found that the twin who slept more than 9 hours was about half as likely to gain weight as the one that slept only 7.

Sleep deprivation affects your hunger urge. If you sleep less, you feel like eating more and you probably do. That’s because not sleeping increases your body’s level of ghrelin, the hunger hormone and decreases leptin the “I’m full” hormone.

A sleep study in Finland with middle-aged adults who had sleep problems found that women had greater sleep related weight gains than men. Though men were also affected. The study indicated that it seems the fewer hours you sleep the more calories you tend to eat the next day.

If you want a good night sleep here’s are some things to consider:

Exercise: Don’t exercise too late in the day. So many of us go to the gym after work but it can keep you up at night. Late exercise can prevent the body from making sleep-inducing melatonin for several hours.

Caffeine: It can take 6 or more hours to wear off. Having that cup of coffee after dinner, even with a low-fat dessert, may not be such a good idea.

Alcohol: A couple of drinks with dinner can wake you up in the middle of the night and make it hard to get back to sleep. I have a friend who swears by a glass or two of wine at lunch but never alcohol after 2pm. She says she sleeps like a baby at night. I think if I had a glass or two at lunch, I’d sleep like a baby at 2pm and be up for the night at 5.

Stress: And then there is our old buddy stress. We all have some level of stress and how we deal with it can keep us up at night. Getting yourself relaxed in quiet, dark, temperature controlled environment can relieve stress and induce a desire and ability to sleep.

So, what’s it going to be, wide awake at 3am or getting that beauty sleep and waking up lighter and brighter on your toes? Learning to get a good night’s sleep is a process. Don’t stress over it, it may keep you up at night.

Exercise and Sleep: Use Your Workout to Stave Off Insomnia

Agnes Green/25 August 2023/ All MFN blog/

Like sleep, exercise is a free, relatively easy-to-access fountain of youth—especially for those of us who are more or less able-bodied. If you are one of between between 50 and 70 million American adults who chronically suffer from a sleep disorder, take heart. Among the many tricks that add up to a healthy sleep hygiene, you can harness the power of exercise and find that as a result you are getting more rest at night.

It is important, however, to realize that the relationship between exercise and sleep is not as simple as the formula that says more exercise always leads to more sleep. The effect of exercise on sleep can vary from person to person and depend on the time of day, length of time from workout to bedtime, intensity of exercise, the type of workout (cardio vs. strength-training vs. yoga), food and drink consumed, and fitness level. And sometimes we have to deal with other exercise-related complications: If you, say, have the misfortunate of incurring a back injury from exercise, factors like the kind of mattress you sleep on suddenly matter a great deal.

All these variables notwithstanding, it is generally true that a physically active life tends to lead to getting more and deeper sleep on a regular basis. A meta-study back in the 90s found that for the general population, exercise improves the metrics of sleep quality. The length of deep sleep, amount of REM sleep, and total sleep time all tend to increase with exercise. And, at the same time, sleep onset latency (how long it takes to fall asleep) and sleep fragmentation (middle-of-the night wake-ups) tend to decrease. A study published in the journal Sleep found that increasing physical and social activities among older adults resulted in more of the higher-quality slow-wave sleep and showed improvement in memory-oriented tasks.

But, according to a study of sleep habits of adults in their 60s published in The Journal of Clinical Sleep Medicine, effects of daily exercise on sleep habits might be more complicated than expected. Additionally, in the short run, sleep might have more influence on exercise than vice versa. One surprising thing that was clear is that if you sleep well tonight, you are more likely to get beneficial exercise tomorrow. The reverse causal relationship in the short run is not as clear. The study participants’ insomnia improved as a result of a moderate endurance exercise program that amounted to three or four 30-minute workouts a week—but only after four months. That’s when exercisers saw the benefit of sleeping more deeply and, on average, 45 minutes longer than before. One lesson, then, is that it’s worth it to keep at it with workouts for a few months in order to see a steady and lasting effect on sleep.

Too much exercise can, however, lead to sleep disturbances. Ultrarunners and triathletes can sometimes run into this problem. For one, running attracts the more active, type-A personalities who tend to get off on the runner’s high.

“I think with the general population, vigorous exercise leads to reports of better sleep quality,” says Amy Bender, a Calgary-based researcher at the Canadian Sleep Society who helps Team Canada Olympians fall asleep. But she notes that in case of elite athletes whose workout routines are extra intense, too much exercise leads to troubles sleeping. According to a study published by Medicine and Science in Sports and Exercise, insomnia is one of the symptoms of the overtraining syndrome. Most of Americans, though, are at risk for what might be called … the undertraining syndrome?

Another area of conflicting information when it comes to exercise and sleep is the timing of workouts. Some respected medical resources recommend keeping your workout away from bedtime. The National Institutes of Health, for example, recommends not exercising two or three hours prior to bedtime. The idea is that vigorous exercise, especially of the aerobic sort, can be too rousing and the resulting adrenaline spike does not promote sleep. Harvard University sleep experts, too, caution that “exercise stimulates the body to secrete the stress hormone cortisol, which helps activate the alerting mechanism in the brain.” As a result, they recommend planning to be done with workouts three hours prior to bedtime.

However, a poll conducted in 2013 by the National Sleep Foundation found that people who exercise in the few hours before bedtime report sleeping just as well as those exercising earlier in the day.

“The timing of exercise ought to be driven by when the pool’s lap lane is open or when your tennis partner is available or when you have time to get away from work, not by some statement that has never been validated,” says Barbara Phillips, a University of Kentucky sleep medicine specialist who was one of the researchers working on the poll.

Our solution? Since we each know our bodies best, we can pay attention to whether or not exercising late in the day has effect on our sleep. If need be, tweak the time of exercise. If you find that exercising too close to bedtime winds you up, try saving the more quieting yoga or the more drowsiness-inducing strength workouts for the evenings and do aerobic exercise farther away from bedtime.

So long as you keep these tips in mind, along with the basic sleep hygiene guidelines, you are well positioned to draw from the two fountains of youth.

Sweet Dreams: 5 Tips for Sound Sleep and a Healthy Brain

Aaron Tribby, M.Ed./14 September 2021/ All MFN blog/

It doesn’t matter what age you are, getting a good night’s rest is essential for your physical and mental health. Taking the time to recharge every night is especially vital because sleep and brain health are closely related. However, as we age, sleep doesn’t always come as easily as it used to.

In a 2003 poll, the National Sleep Foundation found that over 48% of older adults experience symptoms of insomnia more than twice a week, and the National Institute on Aging reported that insomnia is one of the most common problems experienced by adults aged 60 and over.

Insomnia and sleep disruptions have been known to worsen health conditions like Alzheimer’s disease and increase your risk factors for developing other health problems, including heart disease, Type-2 diabetes, and hypertension. Let’s dig into the science behind sleep and what are our five best tips for a good night’s rest!

Why sleep is so important to our bodies

Sleep gives your body some much-needed rest, but it’s also vital for maintaining your cognitive health. When you lie down to sleep at night, your body takes this time to cleanse your brain of toxins and waste. The space between your brain cells actually enlarges during sleep, allowing your body to wash out harmful substances like beta-amyloid proteins, which researchers have linked to the formation of Alzheimer’s disease. It follows, then, getting enough sleep can help ward off Alzheimer’s disease.

A poor night’s sleep has also been tied to forgetfulness and lapses in memory. Because sleep is the vital period when our brains take time to consolidate our memories, not getting adequate sleep makes you more likely to forget things during the day. A good night’s rest is one of the most powerful weapons in your arsenal in the fight against mental aging.

Why getting enough rest is more difficult as we age

Production of the “sleep hormone” melatonin naturally decreases with age, making it harder for older adults to fall asleep and stay asleep. The aging process also causes changes to the body’s natural circadian rhythm, which can make you get tired earlier than usual. Because of this, older adults are also more likely to experience restless sleep and waking up throughout the night.

Environmental factors can also be to blame, such as stress or a lack of structure in your life. Recent retirees sometimes have a hard time adjusting to changes in their schedule, which can lead to fitful sleep.

How to get a good night’s sleep: build healthier sleep habits

Now that you know why a good night’s sleep is so vital, you’re probably wondering how you can improve the quality of your own rest. If you struggle with tossing and turning or restless nights, don’t worry. The good news is that healthy sleep habits are universal and can be practiced by anyone of any age.

It’s never too late to establish a healthy nighttime routine! Here are our 5 best tips to help you combat insomnia, in no particular order.

Work up a sweat

Exercise helps to keep you in good shape, but did you know that exercising can also improve your sleep? The Sleep Foundation has demonstrated a clear link between exercise and improved sleep quality in adults. Try using a fitness tracker, which can be useful to show your progress and motivate you. To rest easier at night, try going for a brisk walk or bike ride outside. Exposing yourself to sunshine and fresh air can improve circadian rhythm, so you can stay active with your favorite outdoor hobbies like gardening and fishing. Just be careful not to exercise too late in the day–getting worked up too close to bedtime may actually keep you awake!

Don’t nap during the day

Napping is common among older adults and retirees, with research showing that around 25% of older adults take naps daily. But did you know that your daily power nap may actually be doing more harm than good?

It’s true. While a brief nap can be beneficial for a boost of energy, excessive napping can disrupt your circadian rhythm and make it harder to fall asleep at night. If you absolutely must have a nap, try to take it earlier in the day and make sure to sleep for no more than 30 minutes.

Establish a bedtime routine

Human beings are creatures of habit, so practicing good habits before bed can help improve your rest. If you don’t already have one in place, try establishing a nightly routine before drifting off to sleep.

You can engage in soothing activities like taking a bath, reading a book or meditating to relax before bed. Sleep comes easier in a cold room, so make sure that your bedroom is cool before you lie down. Always try to fall asleep at roughly the same time every night to establish routine, and make sure that you fall asleep while lying in bed–not in a recliner or on the couch.

Turn off the TV

Although many of us like to fall asleep with the glow of the TV to keep us company, staring at screens before bed can actually disrupt your sleep. The blue lights found in common electronic devices like smartphones, tablets, TVs and computers can disrupt your natural circadian rhythm. That’s why experts recommend cutting out all screens and electronic devices before going to bed.

A few hours before your usual bedtime, turn off all your TVs and power down your tablets, phones and laptops. You can replace time in front of the TV with screen-free activities like doing a jigsaw puzzle, playing cards or drawing in an adult coloring book. Instead of sleeping with your phone on your bedside table, try plugging it up to charge in another room. You’ll be less likely to check for texts or emails in the middle of the night and can rest more peacefully.

Cut back on caffeine and other foods

Eating or drinking certain things too close to bed can cause sleep problems. Foods high in caffeine like coffee and chocolate have been shown to disrupt sleep patterns and interfere with melatonin production. Drinking alcohol late at night also could lead to restless sleep because it can cause decreased REM sleep. Never use alcohol as a sleep aid.

If you can’t do without your morning coffee, that’s perfectly all right. Just make sure that it stays a morning cup. Avoid consuming coffee in the afternoon and eating large meals too close to bedtime. Don’t drink too much water before bed, either, if waking to go to the bathroom is a problem for you. If you must eat before bed, try having something to boost your melatonin, like a handful of almonds or a cup of tart cherry juice.

The bottom line

Along with diet and exercise, getting a good night’s sleep is one of the most important things you can do to maintain a healthy mind and body.

If you’ve tried all these tips and nothing works, check with your doctor to see if one of your medications or an underlying health problem may be to blame. Insomnia can sometimes be a symptom of a more serious issue.

Sleep is just one of many tools on your belt you can use to live your best life possible, so try to rest well every night!

We Need More Sleep

Maurice D. Williams, MS/2 March 2021/ All MFN blog/

We need more sleep because we were not designed to be awake each day for 24 hours. I know in today’s society, a lot of us try and are successful at staying awake for 24 hours.

However, I am sure it came with consequences right?

How much coffee or red bull did you have to drink to do it? How did you feel when you finally did get some sleep? I bet that the next morning when you woke up felt horrible, didn’t you?

In today’s blog, I want to highlight three reasons why we all need more sleep. I hope these three things are simple enough for us to put into practice NOW!

#1. Growth Hormone

There is a hormone that our bodies produce called growth hormone. Without it, we make it harder for us to get bigger muscles. Growth hormone also helps with getting rid of body fat and it helps our bones retain calcium. Wow, sounds like pretty important stuff right? Well, if we are not getting enough sleep in general, and enough quality sleep, then, our growth hormone can’t work like it should.

#2. Leptin

During good sleep, our bodies use something called leptin to control our hunger feelings. Well, this hormone can only do its job properly with a good night’s rest. Leptin helps to curb our appetites and gives us a satisfied feeling. However, if we are not getting 7-9 hours of sleep each night (ideal sleep time), then another hormone, ghrelin, will work for us. This is the hormone that gets released to let us know that we are hungry.

We want ghrelin to work for us when we are actually hungry, not because we did not get a good night’s rest. If you’ve awoken starving, it could have been from a lack of quality sleep!

#3. Exercise Suffers

Yep, all that hard work you’ve been putting into exercise becomes null and void without proper sleep. One of the great benefits of lifting weights is the increase in muscle size and as a result, better metabolism that leads to weight loss. Well, lack of sleep is an enemy to protein synthesis (how our bodies make muscle). If your muscles are not getting stronger and/or bigger, then, your metabolism is not working for you.

Also, inadequate sleep leads to your body having a harder time recovering from your workouts. If you cannot recover from your workouts, then you could potentially 1.) injure yourself and 2.) have less slow-wave sleep.

Conclusion

We need more sleep. There is no way around this, folks! Sleep really does our bodies well. I recommend we at least do the following to get more sleep:

Go to bed one hour earlier than you normally do.
Shut down all electronics one hour prior to going to bed.
Meditation
Drink something soothing like chamomile tea

Are Your Sleep Habits Damaging Your Liver?

Rhona Lewis/23 August 2019/ All MFN blog/

Before we talk about which sleep habits are damaging your liver, let’s get to know this organ. The liver performs more than 500 vital bodily functions. Here are a few:

Bile production. The liver produces bile, which helps break down the fat in food.
Glucose storage. It stores sugar called glucose, which gives you a quick energy boost when you need it.
Detoxification. It’s responsible for detoxifying your blood by removing harmful chemicals, such as hormones that have done their job, that are produced in your body.

The Liver’s Working Hours

Plenty is going on in our body when we’re sleeping, but the most important function is detoxification. This happens ideally between 11 pm to 3 am. During these hours, our liver becomes much larger as blood supplies from all over our body converge here.

Researchers monitoring phases of activity and rest in mice saw that the size of the liver gradually increases to about 40% more towards the end of the night and that it returns to its initial size during the day. When the normal circadian rhythm is reversed, this fluctuation disappears. As mammals, our liver works much the same way as the liver of mice. What happens to your liver, and by extension to you, if you can’t sleep during these hours? Can detoxification take place if you’re awake between 11 pm to 3 am? Here are three studies that seem to indicate that you’re heading for trouble if you don’t catch your shut-eye at the right time.

Sleep and Glucose

Studies show that losing a single night’s sleep may affect the liver’s ability to produce glucose and process insulin. This increases the risk of metabolic diseases such as hepatic steatosis (fatty liver) and type 2 diabetes.

Sleep and Liver Fat

As many as 1 in 4 Americans are estimated to have excess liver fat. This can lead to inflammation and damage that could eventually cause liver failure. Fat production in the liver is affected by the circadian rhythm. So says a mouse study conducted at the University of Pennsylvania. The study showed that liver cells change with the time of day and these changes influence gene expression. When mice are asleep and fasting, the genes involved in fat production are active and help prevent the liver from producing fat. Watch out if you’re disrupting your daily cycle with rotating shift work or night flights. This can increase the risk of diseases like obesity and diabetes.

Sleep and Liver Cancer

Researchers have also associated sleep disruption with increased risk of liver cancer. The American Cancer Society reports that 700,000 people worldwide are diagnosed with liver cancer each year. If you’re overweight, you run more of a risk for liver cancer. The same applies if you suffer from chronic sleep disruption. Scientists exposed mice to disrupted light and dark cycles for nearly 2 years. These cycles disrupted the normal sleep cycles of the mice. As a result, the mice developed a range of conditions, including skin disorders, neurodegeneration, and cancer.

Keep Your Liver Healthy For a Good Night

We’ve established that adequate sleep at the right times can keep your liver healthy. Sadly, if you already have liver damage, you’ll probably have trouble sleeping. Liver damage (cirrhosis) can be caused by harmful alcohol consumption, viral hepatitis B and C, metabolic disorders, and non-alcoholic fatty liver disease. Most patients with liver damage have a harder time falling asleep and staying asleep. Their sleep is of poor quality, and in addition to sleeping less, they feel sleepy during the day. We don’t really understand why liver patients struggle with insomnia, but the hormone cortisol probably plays a part in things.

As well as getting to sleep on time, there’s one more thing that you can do to help your liver function: keep calm and relaxed so that your cortisol levels don’t rise. When you wake up in the morning, you usually feel energized. That’s thanks to the stress hormone cortisol that was secreted into your body before you woke up. Stress will elevate the cortisol levels in your blood. Your liver will have a harder time deactivating this hormone. The longer the hormone stays in your system, the harder it’ll be for you to fall asleep.

The Health Benefits of Better Sleep

Sarah Cummings/29 March 2019/ All MFN blog/

The more that time goes on, the more evidence there is that sleep is our friend – possibly one of the best! Do you find that drifting off into sound slumber among today’s full-on society is something that is slightly out of reach for you in your life?

If you’re nodding your head as you read this, and you want to find out how sleep can have a positive impact on your life, then you’ve come to the right place.

Over the course of this article, we’re going to elaborate on the health benefits of sleep and how it can make a difference in your life!

Heart Health

Did you know that the chances of suffering a heart attack or stroke are higher in the early morning hours? [1] It’s thought that this is because of the way sleep interacts with our blood vessels.

If you are experiencing a lack of sleep, then you are considered among those who are more likely to be associated with issues surrounding blood pressure and cholesterol. These are defined as high-risk factors for both stroke and heart disease.

You’ll benefit from a healthier heart if sleep between seven and nine hours every evening, as recommended by health professionals.

Body Repairs

Sleep is your body’s time to be at its most relaxed. This is also the period in which the body busies itself repairing any damage developed from a range of factors, including stress.

When you’re asleep, notably deeper stages of sleep, [2] your body works to repair muscle, organs, and other cells. Chemicals that operate to strengthen your immune system begin to circulate in your blood.

Your body’s cells are able to produce more protein, and these protein molecules are at the root of the repairs your body needs to overcome daily stressors.

Less Stress

When you don’t receive adequate amounts of sleep, your body moves into a state of stress. This means that your body’s functions are put into ‘high alert mode’, with the effects of this ranging from high blood pressure to the increased production of stress-related hormones.

Avoiding high blood pressure is important, because high blood pressure can increase your heart attack and stroke risk. What’s more, when we factor in stress hormones and how they make it harder to fall asleep, it soon becomes clear that sleep is vital to stay for health.

More Energy

High-quality rest gives will make you feel energized and more alert the following day. You’ll be more active and use up the energy you’ve rewarded yourself with, which subsequently opens the door for a good night’s sleep that evening, too.

This knock-on effect creates a healthy cycle that is hard to not enjoy, especially when you are waking up feeling refreshed and ‘full of beans’ to accomplish whatever lies ahead each day.

Enhanced Memory

During sleep, as your body is resting and repairing itself, your brain is hard at work processing the things you have learned that day.

It’s like a filing process, whereby your brain is sorting all the things in their rightful place, creating connections between events, memories and feelings, for example.

The ability to move into a deep sleep is absolutely essential for your brain to form links and memories, and the better quality of sleep you experience, the better your memory will become.

Weight Loss

Some experts believe people who sleep under seven hours each evening, are more likely to be classified as overweight or obese. Researchers believe that this is due to the balance of bodily hormones that affect the appetite of sleep-deprived individuals. [3]

The body’s hormones leptin and ghrelin are both responsible for the regulation of your appetite, and when sleep isn’t at a suitable level, these hormones become disrupted.

The result of the disruption with these hormones is that you will eat more than necessary, and when you eat more than you need to, losing weight – and even maintaining it – becomes a difficult task.
