What are the benefits of sleep?

Sleep plays a vital role in brain function, but effects have been reported throughout the body. Lack of sleep may seem like a trivial problem, but lack of it can have serious health consequences over time..

Sleep deprivation is associated with increased activity of the sympathetic nervous system (fighting or running). Although beneficial when exercising or trying to take the bus, constant activation puts your body under chronic stress. This can affect your metabolism and circadian rhythm and cause chronic systemic inflammation. Chronic inflammation is associated with diabetes and cardiovascular disease, arthritis, general body aches, depression and anxiety, gastrointestinal problems, weight gain, and frequent infections..

  • Afternoon nap helps the brain

The afternoon nap helps the brain

Many of the world's brightest minds or leaders who have changed history, including Albert Einstein and Winston Churchill, have slept in the afternoon as a regular part of their daily routine. Scientists have shown that a 30- to 90-minute nap during the day can have benefits for the brain compared to a night's sleep.

In fact, there is various research that has proven that an afternoon nap, or getting enough hours at night, helps to significantly reduce cortisol, the hormone responsible for stress.

When the brain feels stress, it initiates the release of epinephrine into the bloodstream. In turn, this triggers the release of cortisol to keep the body revitalized and alert. This is useful if you flee from a bear or any other threat, for example, but it can have negative consequences for your health if your body remains in this state constantly when, in reality, there is no danger, but a state of anxiety many times caused by day-to-day issues.
