Sleep is one of the great mysteries of life. Like gravity or the quantum field, we still don't understand exactly why we sleep—although we are learning more about it every day.
We do know, however, that good sleep is one of the cornerstones of health.
Six to eight hours per night seems to be the optimal amount of sleep for most adults, and too much or too little can have adverse effects on your health.
Sleep deprivation is such a chronic condition these days that you might not even realize you suffer from it. Science has now established that a sleep deficit can have serious, far reaching effects on your health.
For example, interrupted or impaired sleep can:
- Dramatically weaken your immune system
- Accelerate tumor growth—tumors grow two to three times faster in laboratory animals with severe sleep dysfunctions
- Cause a pre-diabetic state, making you feel hungry even if you've already eaten, which can wreak havoc on your weight
- Seriously impair your memory; even a single night of poor sleep—meaning sleeping only 4 to 6 hours—can impact your ability to think clearly the next day
- Impair your performance on physical or mental tasks, and decrease your problem solving ability
When your circadian rhythms are disrupted, your body produces less melatonin (a hormone AND an antioxidant) and has less ability to fight cancer, since melatonin helps suppress free radicals that can lead to cancer. This is why tumors grow faster when you sleep poorly.
Impaired sleep can also increase stress-related disorders, including:
- Heart disease
- Stomach ulcers
- Mood disorders like depression
Sleep deprivation prematurely ages you by interfering with your growth hormone production, normally released by your pituitary gland during deep sleep (and during certain types of exercise, such as Peak Fitness Technique). Growth hormone helps you look and feel younger.
One study has even shown that people with chronic insomnia have a three times greater risk of dying from any cause.
Lost sleep is lost forever, and persistent lack of sleep has a cumulative effect when it comes to disrupting your health. Poor sleep can make your life miserable, as most of you probably know.
The good news is, there are many natural techniques you can learn to restore your "sleep health."
Whether you have difficulty falling asleep, waking up too often, or feeling inadequately rested when you wake up in the morning—or maybe you simply want to improve the quality of your sleep—you are bound to find some relief from my tips and tricks below.
