Too much or too little sleep is harmful to health. A unique study conducted by American experts has revealed that not only insufficient but also excessive sleep can lead to serious health problems.
It has been proven through multiple studies in the past that inadequate sleep can be a cause of heart disease, stroke, neurological disorders, physical health issues, and diabetes.
Furthermore, not getting complete and peaceful sleep can also contribute to diseases like depression, but now the drawbacks of excessive sleep have also come to light.
According to research published in a medical journal, experts examined the mental health and sleep duration of around 40,000 individuals of middle age.
After examining the sleep duration records of all individuals and observing the changes in their brains and the medical complexities arising during the research, it was found that noticeable changes occur in the neural networks of the brain in the case of too little or too much sleep. Particularly, there are risky changes in certain parts of the brain that play a crucial role in nerve function, including memory.
According to experts, both sleeping less than 7 hours and more than 9 hours lead to changes in the brain that can result in diseases like stroke and dementia.
In both scenarios, changes occur in the brain that can lead to stroke and dementia, so humans should maintain a regular and appropriate sleep pattern.
Although the experts did not explicitly specify the duration of complete and standard sleep, it is evident from their research that individuals should aim for at least 7 hours of sleep.
The researchers did not clarify whether a person who sleeps less than 7 hours or more than 9 hours for a few weeks will experience changes in their brain leading to stroke and dementia or not.
