Sleep

It’s getting more and more obvious how important role sleep has in our lives. Sleep enjoys renewed attention from scientists and medical practitioners, and unlike with nutrition there is little disagreement about what constitutes good sleep and what are its benefits.

Sleep has many functions – from …. Through restoring hormonal balance, to storing new and connecting new and old information. It is a neurologically and metabolically active state, and it’s important that you will not disrupt it with “sleeping” pills which just sedate higher parts of your brain.

Lack of sleep, or bad sleep, has many negative consequences. To use words of Matthew Walker, PhD, “Routinely sleeping less than six or seven hours a night demolishes your immune system, more than doubling your risk of cancer. Insufficient sleep is a key lifestyle factor determining whether or not
you will develop Alzheimer’s disease. Inadequate sleep—even moderate reductions for just one week—disrupts blood sugar levels so profoundly that you would be classified as pre-diabetic. Short sleeping increases the likelihood of your coronary arteries becoming blocked and brittle, setting you
on a path toward cardiovascular disease, stroke, and congestive heart failure.” …reference on this book!

Sleep deprived kid will have most of the symptoms of ADHD. If this is not scary enough, bad sleep quality both contributes to and is reinforced by all major psychic conditions – depression, anxiety, and even suicidality.

Sleep has effect on our higher cognitive functions – and lack of it causes us to make poor decisions, be less kind to others, and even alters our morality (sleep deprived people cheat more often).

Quality of sleep is defined by 3 important factors
– Distribution of sleep phases
– Total duration of sleep
– Timing of sleep
