Are Your Sleep Habits Damaging Your Liver?

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

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.

Conclusion

As you may have realized throughout this article, sleep has the ability to have a bearing on many of the chemicals and processes that help your body to function. This is what makes sleep such an important function in all of our lives.

Sleep: An Essential Component to Maintaining Health

I have the answer to making you feel calmer, more energized, with no side effects, help with depression, lose weight, improve your for focus and productivity at work, regulate your hormones and boost your immune system. Sleep does all of this and more. 

Sufficient sleep is an essential to maintain health.

Getting enough sleep improves:

  • motivation
  • supports brain health
  • recovery of muscle strength
  • speed
  • muscle glycogen (stored energy in the muscles)
  • cortisol (stress) regulation
  • memory

Two thirds of adults in developed nations do not get enough sleep!

Less than six hours of sleep compromises the immune system and doubles cancer risk.

A tired brain isn’t able to communicate its needs properly, which can lead to imbalance and unhealthy habits.

Those who are sleep deprived also have a slower reaction time than to those who are rested. You can take all the vitamins and drink all the caffeine you want, sleep deprivation is sleep deprivation. Sleep enables the body to heal itself. Sleep actually is not passive, but studies show during some sleep phases, parts of the brain are more active then they are when you are awake.

The shorter your sleep, the shorter your life span. For athletes, insufficient sleep can be the reason for decreased performance and increased injury risk.

Adults should sleep 7 or more hours per night on a regular basis to promote optimal health. Less than five or six hours of sleep can negatively impact human performance, metabolic health, mental health, cardiovascular health, immune function, mortality, pain, general health. More than 8 hours a night can improve all of the above.

As you age, you sleep less and you spend less time in slow wave sleep. Amyloid beta is cleared from the brain during sleep and more slowly from the aging brain. Worsening amyloid deposition is seen in people with shorter sleep durations, or worsening sleep quality. Don’t count on recovery methods to contract little sleep and a poor diet. Sleep and nutrition are not recovery. Modifiable risk factor for Alzheimer’s disease is not enough sleep!

As you rest, your body and brain are preparing and rebuilding themselves. Growth hormones, which promotes cell reproduction and regeneration, is released into the bloodstream and the production of certain types of immune cells peaks. Sleep also helps to regulate hormones associated with weight gain. A study on sleep deprived men found that when they got less sleep, levels of gherkin (the hormone that increases appetite) rose. Lack of sleep can result in weight gain. Woman who sleep five hours a night were 15 percent more likely to be obese than those who slept seven hours. Being sleep deprived contributes to weight gain and makes weight loss difficult.

Good nutrition is amazing. Meditation is amazing. But nothing makes up for lack of sleep, nothing.

Sleep slows your heart rate and breathing and causes your blood pressure to drop. It also changes the frequency of your brainwaves. Delta waves (the slowest frequency brainwaves), which are linked to deep healing, only occur during the deep part of your sleep cycle. These are the same brainwaves experienced in a meditative state. Production of delta waves is associated with a drop in the production of the stress hormone cortisol. Lack of sleep have an aging impact on the brain and skin.

Some tips to create a sleep friendly bedroom:

  1. Black out curtains, the darker the room the better.
  2. Keep your bedroom decor simple and calm, clutter free, work papers out of sight.
  3. Blue walls perhaps or blue in your room.  Gentle blue tones are widely believed to have a calming effect.
  4. Keep a notepad by your bed so you don’t have to worry about staying awake because you don’t want to forget something, just write it down and go back to sleep.
  5. Pre sleep meditation and calming music.

Some tips for quality sleep:

  1. Institute a tech curfew. The light radiating from TV, phones, computers, iPads can disrupt the circadian rhythm. A study at Harvard University Medical School found particular frequencies of light disrupted the sleep inducing hormone melatonin. Turn off all devices at least an hour before bedtime. If you must read on your laptop or iPad before bed, download the blue light filter app. The more amount of screen time used, the less sleep. The circadian clock regulates our sleep; using technology near bed time interrupts the natural circadian rhythm clock and negatively impacts sleep. The top 25% of social media users were 2-3 times more likely to have disturbed sleep than those in the bottom 25%.
  2. Alcohol. You fall asleep more quickly, but the quality of sleep is poor, and REM sleep is decreased.
  3. Exercise regularly. Just not right before bed — that can have the opposite affect.
  4. 65 degrees is the optimum temperature for a good night sleep. If you are too hot, you are more likely to feel restless.
  5. Try herbal tea with chamomile and or valerian root.
  6. Imagine a tranquil natural scene, this visualization could make you relax. Studies at Oxford University showed that those who used this technique would fall asleep twenty minutes sooner than those who did not picture the tranquil scene. Avoid counting sheep — the study showed it took people longer to fall asleep!

Restful sleep is key ingredient to living a miraculous life. Real sleep!

“Lack of sleep is another way we block our power, creativity, and intuition.”
–Huffington Post President and Editor-in-Chief Arianna Huffington.

We often measure how productive we are based on how hard we work and how little sleep we get. This mentality is negatively affecting our health and overall well-being!
