Lack of sleep slows down brain function

Sleep plays an important role in human health, including performance and mental alertness. Experts recommend sleeping an average of eight hours a day to maintain health and performance. But what if you feel great after six or five hours of sleep? New research shows that lack of sleep can negatively impact your mental performance, even if you feel rested.

Scientists from Brigham Hospital in the USA conducted an experiment in which twelve volunteers slept differently over the course of a month. In the first week, the subjects were given the opportunity to sleep 10-12 hours a day, and in the next three weeks they slept 5-6 hours a day and simulated an inverted circadian rhythm, which is comparable to constant jet lag.

Participants in the experiment took a computer test in which they had to quickly notice visual objects. The study, published in the Journal of Vision, found that lack of sleep slows down the brain's response, even when a person feels rested. In addition, if wake time shifted toward nighttime, reaction times slowed even more.

This data is relevant for those who work night shifts, must be on duty, or frequently fly between time zones. But what can be done to combat the inevitable inhibition of mental response? A few tips can help combat insomnia:

1. Maintain a sleep-wake schedule and get enough sleep.

2. Avoid caffeine and alcohol before bed.

3. Create comfortable sleeping conditions: a quiet and dark room, a comfortable bed.

4. Relax before bed, such as taking a warm shower or reading a book.

5. Avoid prolonged use of technology before bed, as it may interfere with falling asleep.

Lack of sleep can lead to serious health and performance problems. Therefore, it is important to monitor your sleep and wakefulness to maintain good health and mental alertness.
