Daytime sleep prevents brain shrinkage

A daytime nap helps a person maintain a keen mind. To prevent brain atrophy: The brain shrinks by 0.2 to 0.5% per year from age 35, and much faster after age 60.

This can lead to age-related changes in the mind, memory impairment, and even cognitive impairment and even dementia. A recent study found that people who sleep during the day have a larger brain volume, which reduces the risk of a large brain loss over time.

The study, carried out on 35,080 residents, was not limited to the analysis of the frequency of daily sleep reported by participants.
This metric can be misleading, because people can sleep not only because of desire, but also because of disorders such as high blood pressure.
Or heart problems that cause drowsiness and affect the rate of brain tissue contraction.

Instead of questioning, researchers focused on the lifelong genetic predisposition of people to regular daytime sleep. This allowed more precise determination of whether the process of sleep itself affects the brain. Dr. Victoria, senior author of the study from University College, noted, "Our findings show that for some people, short daytime sleep can be part of a prevention strategy to avoid dementia.
Which helps to keep the brain healthy with age. I hope that studies like this, demonstrating the health benefits of short sleep, will help reduce the stigma still attached to adult daytime sleep."

Hygiene

Healthy sleep is essential for all people and especially for people with a risk factor for cardiovascular disease.

Day sleep:

Hiding the daytime sleep can vary: some people may take a nap for ten minutes and wake up refreshed, whereas others may require up to two hours to fully rest. To begin the discussion, take the average of 20-30 minutes of daytime sleep.

Many people think that spending time sleeping during the day is inappropriate, even if it is short, for only 10 to 15 minutes. They do not go to bed every day, but only when they are very tired, fearing insomnia at night. Others, on the other hand, can sleep for 20 to 30 minutes in a short daytime period throughout their adult lives, while sleeping well at night.

Sleeping during the day: protecting the brain

Studies show that during daytime sleep, production and circulation of cerebrospinal fluid, known as CSF, increases. This creates a kind of "cushion" of moisture around the brain and spinal cord. During 20-30 minutes of sleep, CSF actively removes toxic metabolic products from the brain.

Thus, a short daytime sleep of 20-30 minutes fulfills the cleansing function and literally "brainwashes". Importantly, among the excreted substances is amyloid protein, which can form plaques in Alzheimer disease.
