Here’s Why You Should Get More Sleep for a Healthier You

What is something we all want but most of us don’t get enough of? Sleep is definitely a popular answer to that question. Most of us crave sleep and look forward to a good night of rest. Unfortunately, a lot of us don’t get nearly enough sleep as we should. Getting enough sleep is an important factor in living a healthy lifestyle but it is usually the first thing people cut out of their lives when they are busy.

There is a saying, “I’ll sleep when I’m dead”. This is definitely bad advice and would never be recommended by a healthcare provider. There have been several studies done and articles written that all conclude that a lack of sleep will negatively affect your health in a variety of ways. Let’s dive into some recent research and articles on sleep.

Don’t Sleep With The Lights On

A small research study published in March 2022 suggests that sleeping with a moderate amount of light can have negative effects on cardiovascular health and metabolism. The study had 20 participants. On the first night of the study, they had all the participants sleep in a completely dark room. On the second night, they had half of the participants sleep in a room with 100 lux of overhead light. 100 lux of light is described as enough light to be able to see to get around the room but not enough light to read. The researchers conducted tests on the participants during sleep and after waking up. They concluded from their research that sleeping with light can interfere with metabolism and can increase the risk of chronic diseases. The people who slept with the light on had increased insulin resistance in the morning which puts them at an increased risk of many chronic diseases (Mason, et al. 2022).

A Lot of People Don’t Get Enough Sleep

A recent survey conducted in January 2022, found that only ⅓ of Americans report getting good quality sleep. The survey had over 3,000 participants. One of the main points that were highlighted was that emotional and mental health were important factors that contribute to the quality of sleep. 96% of the survey participants reported that with increased stress, their restlessness also increased. The researchers that conducted the survey suggest that nutrition, exercise, environment, and mental health are all factors that contribute to a person’s sleep quality (Dean, 2022).

Your Body Requires Sleep To Function

The National Institutes of Health did an article in May 2021 about why sleep is important to overall health. Dr. Marishka Brown was quoted saying, “Healthy sleep encompasses three major things, one is how much sleep you get. Another is sleep quality-that you get uninterrupted and refreshing sleep. The last is a consistent sleep schedule”.

Dr. Maiken Nedergaard says that sleep is important for the brain. During sleep, your brain is working by draining toxins. Per Dr. Nedergaard, “When we sleep, the brain totally changes function…it becomes almost like a kidney, removing waste from the system”.

Dr. Kenneth Wright Jr says that sleep is when your body repairs everything from your blood vessels to your immune system. Per Dr. Wright, “There are certain repair processes that occur in the body mostly, or most effectively, during sleep…If you don’t get enough sleep, those processes are going to be disturbed” (U.S. Department of Health and Human Services, 2021).

You Will Probably Gain Weight If You Aren’t Sleeping Enough

A 2022 study published in the Journal of American College of Cardiology studied the effects of having an inadequate amount of sleep on weight gain. Researchers found that a lack of sleep led to a 9% increase in abdominal fat (Covassin, et al. 2022).

Another similar study published in 2022, in the JAMA Internal Medicine Journal analyzed increased sleep and the effects on calories consumed. There were 80 participants that normally only slept 6.5 hours a night. They had a portion of the participants increase their sleep time to 8.5 hours a night for two weeks. The researchers found that the participants who got more sleep consumed 270 fewer calories daily. They concluded that getting enough sleep could help lose weight and prevent obesity (Tasali, et al. 2022).

Improving Your Sleep

As you can see from the research and articles we reviewed, sleep is important. Seriously, this is no joke, people need to start prioritizing their sleep. Instead of staying up late scrolling through tik-tok or watching Netflix, start making good sleep a priority. Some people have no issues falling and staying asleep while others struggle. If you have struggled with sleep there are several methods you can try to help. It isn’t a good idea to automatically jump directly to using sleep aid medications because your body can build a tolerance to these and you may need more as time goes on. A healthier option is to try lifestyle changes first.

First, be consistent with your sleep. Choose a bedtime and wake time to stick to. Try this out for at least a week and see what happens. Our bodies like schedules and consistency. Your body will get used to the schedule and will start to get used to going to bed and waking up at the same time every day.

Make your bedroom optimal for sleep. You want it dark while sleeping. Getting black-out curtains may be a good investment. Make sure the temperature in the bedroom is comfortable for you. If needed try a fan that will provide a soothing noise and cooler temperature. Bedding is also a good investment if you have trouble sleeping. Getting bedding that you like helps you relax.

Get rid of all electronic devices while you are sleeping. This includes TVs, phones, tablets, and computers. The light that these electronics give off will keep you awake and does not promote sleep.

During the day make sure to get some exercise. Getting physical activity is good for your health in several ways including improving sleep quality. Avoid large meals before bedtime. Having meals before bedtime could cause acid reflux and no one wants to go to bed feeling bloated. Avoid caffeine during the later day hours. Consuming caffeine late in the day can hinder good sleep habits.

Do something before bed to help you relax and wind down from your day. Try a bath, reading a book, or drawing to help clear your mind before laying down for the night.

If you try these methods and are still struggling with sleep, make an appointment to discuss your sleep difficulties with your healthcare provider. Start keeping a sleep journal to track how much sleep you are getting and to analyze any factors that may be affecting your sleep. Don’t give up on getting good sleep. It is important to your health and well-being to get good sleep.
