In modern times, it has become common to go to bed late, but chronic poor sleep can negatively affect brain function and memory ability. Some studies point to a link between sleep disorders and the development of forgetfulness. Medical professionals agree that quality sleep contributes to maintaining brain health. Specialists have explained how many hours of sleep the brain needs and what consequences sleep deprivation entails.
Dr. Sanjay Manchanda, head of the sleep medicine department at Sar Gangaram Hospital, shared information with Aajtak.in. He noted that there is a two-way relationship between sleep and forgetfulness, such as Alzheimer's disease. This means that prolonged sleep disruption can cause changes in the brain that potentially increase the risk of developing Alzheimer's. At the same time, early signs of Alzheimer's disease itself can also worsen a person's sleep quality.
During sleep, the brain actively engages in the process of removing accumulated unnecessary substances. If a person constantly sleeps little or their sleep is interrupted, this brain cleansing process occurs inefficiently. As a result, the production of a certain protein begins to decrease in the brain. Dr. Manchanda emphasized that it is critically important not just to lie in bed, but to achieve deep sleep.
According to Dr. Manchanda, seven to eight hours of sleep are required for optimal brain function and memory strengthening. If a person only sleeps four or five hours, it affects brain function. Although larger studies are still needed to determine whether treating sleep disorders can prevent Alzheimer's, it remains clear that chronic sleep deprivation cannot be ignored.
People who sleep only four or five hours daily put their brain at risk. This can increase the probability of developing Alzheimer's, although it does not guarantee inevitable illness. Nevertheless, if you notice that your sleep is insufficient or you cannot sleep properly, you should consult a doctor.
