There is no doubt that a good night's sleep is essential for our well-being. When we go through sleepless nights, we feel the impact on our body and mind, facing the challenges of the day with difficulty.
Now, a new study further highlights the importance of what is appropriate. He reveals that the sleep deprivationcan lead our brain to “eat” itself, causing significant damage.

A group of Italian neuroscientists led by Dr. Michele Bellesi, from the Polytechnic University of Marche, were responsible for the research, the results of which were published in Journal of Neurosciences.
The team set out to understand how the brain reacts when it is being deprived of adequate sleep. What happened was alarming: processes involved in self-destructive and abnormal behavior after a few hours of sleep deprivation.
And the most worrying news is that the resulting damage appears to be irreparable. Check out details about the study!
Our brain is an extremely complex system with countless functions and delicate connections. When we enter adeep sleep, a sort of “maintenance and cleaning team” takes over.
This team is responsible for eliminating old and worn elements, as well as repairing damage that may have occurred. Two crucial parts of it are microglial cells and astrocytes.
Microglial cells play a key role in removing damaged and nerve cells through a process called phagocytosis.
On the other hand, astrocytes coordinate synapse processes, which are essential for communication between specific cells.

When we don't get enough sleep, these necessary functions can be disrupted. As a result, microglial cells begin attacking brain cells instead of eliminating damaged ones.
The imbalance can cause irreparable damage to the brain and contribute to a series of mental health problems and cognitive problems.
The research led by Dr. Michele Bellesi and her team raise an additional concern about the effects of sleep deprivation on our brains.
It suggests that the destruction of useful brain material caused by this abnormal microglial activity in the absence of sleep is irreversible.
This means that even if we try to make up for lost hours of sleep later, damaged or destroyed cells cannot be recovered.
