According to the National Institute of Neurological Disorders and Stroke, getting quality sleep – and getting enough of it – is as critical as healthy food and clean water. Sleeping helpsmaintainefficient pathways in your brain,preservescommunication lines between nerve cells (neurons), and removestoxins in your brain that build up while awake. Getting enough deep sleep, or REM, helps to fight a person’s risk of developing brain-related diseases.

According to a study by theNIH, an estimated 50 to 70 million Americans suffer from chronic sleep disorders. The Mayo Clinicsuggestsseveral techniques people can try that may help them improve their sleep and,in turn, their brain health. Several of these include:

  • Pay attention to what you eat and drink –Try not to go to bed right after eating,butdon’tgo to bed starving either. Also, try to avoid caffeine, alcohol,andnicotine right before you go to bed as their effects often take hours to wear off.

  • Stick to a sleep schedule –Work on going to sleep at the same time every day. Consistency in anything isvery importantfor favorable long-termresultsand the same goes for getting adequate sleep. 

  • Create a room conducive to quality sleep –It isgenerally suggestedthat a dark, cool, and quiet room is the most beneficial condition for high-quality sleep. Turn off the lights and bright screens like a television or computer to help you reach REMsleep.

  • Avoid too much daytime napping –Napping isvery healthyand, in most societieswhere people live longerand arehealthier, napping is common.

Anthropological studies have discovered that casual exercisegreatly benefitsthose whose lifestyle is conducive to regular movements throughout the day, every day.

Blue Zone co-founder, Dan Buettner, was asked what physical activity is best for healthy longevity. His answer was, “The one you enjoy most,” because then you will do it often.If you like jogging, get out and jog. If you like walking, swimming,orbiking, get out and do it. Youdon’thave to go overboard, but three to four days a week can bevery beneficialfor your brain health.
