How sleep affects our brain!

by SmartBrainTips

“I’m tired, I need some sleep,” is a sentence most people often say. How many vacations we actually need to function normally is a question to which a new study from Belgium might answer.

According to the study, two key factors influence sleep and rest to keep our brain functioning normally.

Researchers have divided sleep and dreaming time into two clocks, one is an internal clock that has a time frame (day and night), while the other is an hourglass and refers to time without sleep. The study explains the principle of the hourglass as pressure on the body, because the longer the body is without rest, the greater the pressure.

The study analyzed data for 33 young people who volunteered to stay awake for 42 hours and to check their mental and physical function at that interval. Also, brain scans were performed during tests to see the brain activity on the chart.

The data showed that the longer the sleep-free period, the worse the test results. Also, brain scans revealed the interaction of two basic biological processes in the central biological rhythm – the first that stimulates the brain to stay awake by day, and inactive at night, and the second, which puts pressure to sleep after too much so-called waking time.

According to the study, if you are awake from 7am to 7am the next day (24 hours), you are more likely to stay up for a few more hours because of a time clock that tells you that the day is not for bedtime. However, after a few hours, an internal “hourglass” will cause pressure to rest on the body.

The primary determinant of sleep is different for each person and is not related to how much you are awake and how much you sleep, but it is a biological rhythm for how much rest and sleep you need.

These findings have shown how two different things affect different parts of the brain, which can be important for scientists to understand how sleep promotes brain function and how sleep loss interferes with it.

There are more negative effects of lack of sleep in addition to brain function itself. People with too little sleep have a higher risk of chronic diseases, as well as diabetes and heart disease. However, realistically, almost no one stays awake for 42 hours or more and is not viewed as a regular thing. There are certain jobs that involve a third shift, and this is not a novelty, and such people most often suffer from insomnia, which is linked to the factor of exposure to artificial light.

Generally speaking, both this and all previous studies on the subject show a pattern: both humans and animals have an internal biological clock that tells them that it is a night for sleep and a day for activity. However, today’s way of life causes the biological clock to shift to a later sleep period, which causes insomnia.

Why are we sleeping?

Despite spending a quarter of our lives sleeping, the real reason behind this habit is still unknown. We know that sleep is crucial to our survival: prolonged periods without sleep can lead to hallucinations or even death.


Scientists say that people younger than 65 need 7 to 9 hours of sleep a day, while seniors 65 or older need 7 to 8 hours of sleep. However, the best indicator of how much sleep you need is the organism itself. Paying attention to the signals that your body sends during the day is a true indicator of your drowsiness and desire to rest.

For the average person, the message is quite simple and it reads: you sleep and rest more because that is how the brain works better.
