Many people have trouble sleeping. Insomnia makes us feel tired and exhausted. In addition, scientific studies show that sleepless nights cause changes in the structure of the human brain.

A study published in the Journal of Neuroscience suggests that a lack of sleep can cause the brain to age faster. Just one sleepless night has been proven to cause brain aging for up to two years in some people.

During the study, the experts examined the MRI results of 134 healthy people. Their ages ranged from 19 to 39. At the same time, they were all placed in different sleep conditions: complete denial of sleep for one day, three hours of sleep each night, and five hours of sleep in five nights. There was also a control group whose participants slept eight hours a day.

It turns out that in people who are completely sleepless during the day, the brain ages by one to two years. But these changes are still reversible with restorative sleep. In the rest of the groups, the participants’ brain age did not change significantly.
