Sleep

About Sleep

It is said that wake time is determined by practical matters. Even better would be to set ideal wake time based on our needs, and fit the day around it. Sleep is critical for health, and we should not mess up our sleep.

Exercise and sleep are a mutually-reinforcing positive loop. [1]. Without good sleep, people get less exercise (energy) due to fatigue.

10% of the adult population has insomnia. Best treatment is CBT, not drugs. A step-wise model is presented for making CBT accessible (scalable, due to time and expense required) -[2]. DIY is first, BSM (Behavioral Sleep Medicine) professional is top.

It is not known how the timing of exercise affects circadian rhythm, but it is known that nocturnal exercise inhibits onset of melatonin. [3]

Nocturnal Awakenings

• It appears natural that most people wake up many times. 9 on average - [4]
• Note that sleep time is NOT the time you go to be and wake up. It is that time minus the awake times. Thus, if you plan on the recommended 8 hours - you need to spend more than 8 hours in bed. It is 55 minutes more on a erage according to available data - [5]. THIS IS A BIG POINT TO HEED FOR ANYONE WANTING TO GET THE RIGHT AMOUNT OF SLEEP, OR IF THEY WONDER WHY THEY are tired if they 'go to sleep fr 8 hours'
• Remember that proper sleep, diet, and exercise are critical physical requirements of health

Training the Mind to Fall Asleep Rapidly

• Author says his insight came from a book, "Insomnia and Other Adult Sleep Problems

• How to train your brain subconsciously to fall asleep in 30 seconds [6]. (1) remove caffeine in training period (2) good diet; (3) exercise; (4) wake at same time, no lingering - which trains your brain it's all it gets, which incentives brain to fall asleep at the same time to adapt. It's the lingering that teaches the brain that it's ok not to wake up, so brain never trains itself to fall asleep immediately. (5) caffeine can be added back once brain is trained.
• Herbal stimulants - peppermint, cayenne, ginger, cinnamon - [7]

Assessment
