The rhythm of modern life forces us to devote less and less time to sleep. For many, a he althy 8 hours of sleep is already an illicit luxury. More and more people are sacrificing full-fledged recreation for the sake of career without suspecting what terrible consequences this has for their he alth.
American scientists from the Lawrence National Laboratory in Berkeley have conducted an extensive study of what parts of the brain are negatively affected by lack of sleep and what this leads to.
Memory Loss
Constant lack of sleep has a negative effect on memory because it disrupts the functions of the hippocampus. This part of the brain is responsible for the transition from short-term to long-term memory. So if you skimp on sleep, you risk starting to forget what you had for breakfast or where you were yesterday.
Outbursts of anger
Excessive irritability and outbursts of unmotivated aggression can also be caused by lack of sleep. Without normal rest, the functioning of the amygdala in the brain is disrupted. This leads to loss of concentration and excessive impulsiveness.
Motricity disorder
If everything falls out of your hands, it may be a consequence of lack of sleep, which has a bad effect on the inferior frontal gyrus. This part of the brain is responsible for psychomotor skills.
Blur
Have you noticed that after a sleepless night, everything around loses its outline and seems to be shrouded in fog. This is because without the necessary rest, the visual cortex of the brain begins to malfunction.

Hallucinations
Lack of sleep leads to hallucinations. A tired brain cannot filter the information that enters it from everywhere, it begins to make mistakes and show us things that are not really there.
False Memories
Except for hallucinations, we can confidently remember anything that was not actually there. False memories of the brain arise due to lack of sleep, when the work of the hippocampus is disrupted, as well as the parietal and prefrontal cortex of the brain
The drying up of the brain
Lack of sleep leads to brain drying, which initially manifests itself in lethargic behavior and apathy. The frontal, parietal and occipital parts of the brain especially suffer from this.
Speech disorders
Malfunctioning of the parietal parts of the brain leads to speech problems such as stuttering or short bridle. They can also be caused by lack of sleep.
Overeating
Lack of sleep can lead to uncontrollable food consumption. This occurs with damage to the frontal lobes and the amygdala of the brain. Remember this, because otherwise no diets will save you.
Making Risky Decisions
When a person is overtired due to lack of rest, he is capable of making risky, even absurd decisions. This is a consequence of the incorrect work of the prefrontal cortex and the insula in the brain, which are responsible for the manifestation of our emotions and the control over them.
Brain Damage
The worst thing is that chronic lack of sleep can even lead to irreversible brain damage. Disruption of the brain stem, which controls automatic functions such as breathing and heartbeat, is particularly dangerous. All signals from the spinal cord to the brain also pass through it.
As you have seen, systemic lack of sleep leads to a lot of different problems. That's why you should take care of your sleep, full rest is the key to good he alth.
