According to researchers at the University of Zurich, a bad habit could have disastrous consequences on our health.

To take good care of your health, restful sleep is as essential as a good diet. Numerous studies have proven the virtues of a good night’s sleep, whatever our age. According to recent information from the Emma brand, more than 8 out of 10 French people have difficulty falling asleep. This can be explained in particular by the stress that many of them feel, but also sometimes by the poor quality of their bedding. Furthermore, a study showed the impact that a very bad habit would have on our body and our brain.

How many hours per night is recommended to sleep?

We often hear that an adult needs 8 hours of sleep per night. However, to recover, not everyone has the same needs and it depends on many parameters. Most of the time, the ideal amount of sleep for an adult ranges between 7 and 10 hours per night, although some people can get by with only 5 hours of sleep. There is also a age at which we sleep lessand it doesn’t get better with age.

What bad sleep habit has disastrous consequences on our health?

According to researchers at the University of Zurich, sleepless nights are a very bad habit that affects our body and brain more than we think, as reported Neon. They sought to know what its consequences are on the latter, and how it reacts in the event of loss of sleep. To carry out their study, they analyzed MRI data from 134 adults, aged 19 to 39, including 42 women and 92 men. This allowed them to measure “changes in the brain after different periods of no sleep and fed this data into a tool that uses machine learning to estimate brain age”.

As a result, they found that a night without sleep ages the brain of the person concerned by one to two years, compared to their actual age. According to researchers, this aging can be explained by the fact that loss of sleep “disrupts the circulation of cerebrospinal fluid, which helps cleanse the brain of toxins”. In other words, the brain has difficulty reorganizing itself and forming new connections between brain cells, and this can lead to cognitive problems. “In contrast, brain age was not significantly altered by acute (3 hours in bed for one night) or chronic (5 hours in bed for five consecutive nights) sleep restriction.”underline our colleagues.

According to scientists, the solution would then be simply to sleep. “Interestingly, after a night of restful sleep, brain age is no different from its initial value”they wrote in the study, specifying that “these changes are reversible by recovery sleep”. “Sleep is fundamental for humans to maintain normal physical and psychological functions”recall the researchers.

What is the impact of sleepless nights on health?

Sleepless nights can have a real impact on your health. Indeed, the consequences can be quite serious, ranging from the risk of developing metabolic and cardiovascular diseases to that of depression. In other words, this must remain very exceptional and certainly not become a habit.
