Your Sleep Habits’ Effect on Your Health
Posted by Vicki | Under Basic Nutritional Requirements
It may not be a nutrient, but your body needs proper sleep to make the best use of the nutrients you consume. As a matter of fact, mounting evidence shows that without at least 7 hours of sleep a night, you are putting yourself at risk for many illnesses in the long term.
Thousands of studies in just the last few years have accentuated the importance of sleep on our health. The reports are staggering, and yet we continue to cheat ourselves out of sleep without paying attention to the consequences.
Effects of Sleep Deprivation
There is significant evidence of the link between lack of sleep and obesity, cancer, heart disease, and diabetes to name a few. At a very minimum, sleep deficiency causes memory and cognitive impairment, decreased performance and alertness, and a weakened immune system. It disrupts crucial hormones and proteins that play a role in defense against disease. It disturbs every physiological function in the body.
With its affect on motor skills, driving with sleep deprivation has been compared to driving while drunk. The National Highway Traffic Safety Administration says that it causes over 100,000 accidents and 1500 deaths per year.
Memory impairment and alertness affects work performance. Fighting that feeling of sleepiness that gets in the way during the day can affect your ability to concentrate and succeed at typical problem solving and other workplace tasks.
The effects of sleep deficiency even accumulates over time. Chronic sleep disorders can result in endocrine dysfunction, gastrointestinal ailments, anxiety and sleep disorders (yes being cyclic), and mood disorders including depression.
The associated anxiety causes the sympathetic nervous system to remain active, suppressing the parasympathetic nervous system which is responsible for our nutrition absorption and immune system.
Sleep and Obesity
Links between lack of sleep and obesity have been studied at length. It has been shown that getting sufficient sleep (at least 7 hours and preferably 8 hors per night) have helped to reach and sustain desired weight loss.
Insufficient sleep affects levels of leptin and ghrelin, two hormones that regulate appetite and body fat. Leptin is produced by fat cells and signals the brain to cause the feeling of fullness. Ghrelin is produced in the stomach and signals hunger. In a Wisconsin Sleep Cohort Study found that participants who slept only five hours a night had lower leptin and higher ghrelin levels.
Other studies have found increased hunger for sweet, fatty and high carbohydrate foods after less sleep, which may be related to higher levels of a stress related hormone cortisol.
So What Health Benefits Does Sleep Provide?
Sleep is responsible for many functions that the body performs, and is beneficial to hormone release, cellular repair, muscle building. Everything from increased energy level and strength to better skin and muscle tone, and even better vision can result from getting enough sleep on a regular basis.
It is absolutely essential for the immune system to be properly functioning. It is the time when neurons are repaired, and brain cells are rejuvenated.
Many hormones are released during sleep, including growth hormone which is for adults restorative and used for muscle repair, while for children is necessary for growth to occur. It also reduces inflammation, and oxidative stress.
Digestion, detoxification, liver function are all key to good health such that even if you get the most nutrient rich foods, they are worthless without them. Sleep is required for these functions to be performed to your body’s best abilities.
What Causes Sleep Disorders?
Of course there are many causes of insomnia, including even toxicity and lack of nutrition.
Aging actually causes our bodies to produce less melatonin, the hormone which regulates sleep patterns. But exercise, good nutrition, and low light and noise near bedtime can encourage our bodies to produce more melatonin.
Good nutrition can in and of itself have amazing benefits on your sleep patterns (I have experienced this myself). Most causes are things that can be easily remedied, such as the following.
- Artificial light (or as in very northern hemispheres, sunlight) late in the evening will cause some people trouble falling asleep. Melatonin is a hormone that is produced by the body which helps with sleep, but it is released when darkness falls. This is why it is important to have a darkened room for sleeping, or wear an eye cover if that is not possible.
- Watching TV or working on the computer until late at night also may disrupt sleep patterns for this reason. Try and make it a habit to turn down lights and step away from the computer for at least an hour before trying to fall asleep.
- Loud music or volume on the radio or television are also disruptive to the production of sleep hormones such as melatonin and serotonin. Turn volumes down low as it gets closer to bedtime.
- Drinking coffee or caffeinated drinks too late in the day will disrupt sleep in some people, or for those who are particularly sensitive to caffein, any time.
- Eating high carbohydrate foods and sweets (this includes alcoholic drinks!) at night cause awakening when the sugars burn off.
- Deficiencies in vitamins, minerals, amino acids, and enzymes may also impair sleep. For example, deficiencies in calcium, magnesium, melatonin, folic acid, and B vitamins may disturb sleep patterns. Leg cramps during the night may be due to a shortage of calcium and magnesium, further disturbing sleep. Some excellent quality supplements are available at SISEL, where customers can receive rebates of up to $1000.
Sleep troubles may be a red flag for more serious disease, since it is known that so many vital functions are dependent on it. And since it may indicate nutritional deficiencies, there are multiple flags that should be going up when you are not getting quality sleep on a regular basis.
Improve Your Odds
Get regular exercise, or at the very least stay active both physically and mentally during the day. Physical activity can include housecleaning, yard work, walking, and just moving around. Yoga is great for relaxation, stretching, and reducing stress. This increases your ability to sleep well at night.
Meditation is a great relaxation technique, especially just prior to bedtime to reduce mental activity and quiet the mind. Focus on breath is the first step and can be key to falling asleep. Check out simple breath-work techniques for some ideas.
Do not eat high carbohydrate foods late in the evening. This will complicate your sleep.
Learn about eating foods in the right combination for your body to properly digest. Eating the wrong variety of foods at dinner will have your body working all night to digest, rather than rest. For example, eat meat with vegetables, not sweet fruits, as they will be digested first, causing the meat to sit and get putrid for hours longer as your body struggles to produce the enzymes and acid levels necessary for its digestion. (I have another post coming on this later on).
Nutritional Supplements for Sleep Aid
Take calcium and magnesium supplements at night. At least 1200 mg of calcium and 300 mg of magnesium at bedtime may provide a sedative effect (do not take these in the morning for that reason!).
B vitamins have a sedative effect. If you take 25 mg of B12, 50 to 100 mg of B5 and B6, this may help prevent insomnia.
Melatonin (3 mcg) can be taken to aid in falling asleep, and has no effect on morning awakening. It also provides an anti-oxidant benefit.
Serotonin is a sleep instigator produced by our bodies from the amino-acid tryptophan. 5-hydroxytryptophan (5-HTP) is a more effective form of tryptophan which has been shown through double blind studies to reduce the time falling asleep as well as the number of awakenings. To increase the sedative effect, be sure that you have adequate levels of B-vitamins, niacin, and magnesium, which are used in its conversion to serotonin. Take 100 to 300 mg with fruit juice (for the carbohydrates) 30-40 min before bedtime.
Test Your Sleep Deprivation
If you think you’ve had enough sleep, maybe you’d like to test your reflexes? Here is a quick little Sheep Dash test for you to try!
Sleep Well, Live Well!









This was a really informative article. I know when I haven’t slept enough, I have to eat to compensate. Your body has to get energy somehow.
Guess I should get to bed soon!
This is a great post! I think sleep is one of the most under-emphasized aspects of health in American society and many modern societies. A lot of people live on a myth that you can gain an hour of useful time in your day by giving up an hour of sleep…but it’s an illusion…your productivity suffers and you almost always lose more than you gain, especially in the long-run.
I have two things to add!
One, sleep and creativity are also linked:
http://www.nytimes.com/2008/09/28/technology/28proto.html
http://en.wikipedia.org/wiki/Sleep_and_creativity
This is especially important for people in careers or positions where their productivity hinges on creativity. Sometimes, a creative solution to a problem could save you hours of work. People who are constantly behind on sleep may be working harder than they need to because they miss out on these creative ways to work more efficiently.
A second one, being a “tea” person, one could ask, how does tea influence sleep? One study found interesting results:
http://www.springerlink.com/content/eebcgnlcg9cgjwvl/
The study found that typical tea use, compared to typical coffee use, had roughly comparable positive effects on alertness as coffee…but tea was less likely to disrupt sleep, possibly because of its lower caffeine content.
This post inspired me to write my own article about tea and sleep:
http://ratetea.net/topic/tea-and-sleep/9/
It’s just a beginning…but I’m hoping it can grow over time. =) Thanks for the inspiration!
Sleep is the time when body engages in auto healing, repair and maintenance.
I enjoyed reading your work! GREAT post! I looked around for this… but I found you!
Anyway, would you mind if I threw up a backlink from my site to your site?
This is a really good read for me, Must admit that you are one of the best bloggers I ever saw.Thanks for posting this informative article.
Fantastic information in your blogpost, I watched a report on tv yesterday about this same thing and since I am getting married next month and the timing could not have been better! thanks for the info!
[...] relaxing effect. One study found that tea improves alertness equally well as coffee, but with less disruption of sleep, due to its lower caffeine levels. There is also some evidence that tea may have other benefits for [...]
Great post Vicki! We all know we need adequate sleep, but thanks for outlining the specific reasons why! I am one of those people who can’t function properly without 8 hours. Sometimes it’s inconvenient, but perhaps for the best–being forced to get the right amount of sleep contributes to a healthy mind and body!
Thank u
May u elaborate more on this:
For example, eat meat with vegetables, not sweet fruits, as they will be digested first, causing the meat to sit and get putrid for hours longer as your body struggles to produce the enzymes and acid levels necessary for its digestion. (I have another post coming on this later on).
I did not understand it well.
Thanks a million for ur amazing effort
Another Stellar article Vicki. The more I read here and take action on what I learn, the healthier I get, or at least get on the road to a healthier body. Thank you for the link to this article. I am a good sleeper 8-9 hours, yet by cutting down on coffee, I am changing my habits and going to bed earlier and getting up earlier and a bit sleepy as I get used to less caffeine and nicotine in my daily routine.
Thanks for the article. Sleep deprivation is one of the most overlooked causes of chronic disease.
Excellent information! Although I hate sleeping, I do not have any problem falling into a sound sleep quickly. The hard part is just making myself get into bed.
Great post Vicki! The link between sleep and obesity is very interesting. My appetite is always higher after poor sleep… Back to bed for me
Thanks Carole! You’ll be glad once you’ve created the habit of making sleep a priority, it has done wonders for me in so many ways!
Count yourself lucky! I’ve never been so good at falling asleep, you are surely blessed! I’ve come to realize it’s important to turn down lights and loud volumes as evening comes on, and staying at the computer or in front of a TV until late can also trick the brain into producing less melatonin, necessary for good sleep!
You and me both Liam, and it’s typically not the healthy foods I crave after little sleep, but the comfort foods, high carb, empty calories, just looking for that sugar high, which of course only leaves me less energetic after it’s over!
I stumbled across this on tonight ( a rather sleepless one ). I believe that not only is this very informative it holds such truth. Thanks a lot for sharing. #aspiringhealthguru
