The Connection Between Daytime Sleep and Increased Risk of Dementia

New Delhi, April 17 (IANS) Compensating for lack of sleep during the daytime may not be as effective as previously thought, warned Dr. Sudhir Kumar, a neurologist based in Hyderabad. According to Dr. Sudhir, daytime sleep is not in sync with the body’s natural clock and can increase the risk of dementia and other psychiatric disorders.

Dr. Sudhir, from Indraprastha Apollo Hospitals, highlighted in a post on that daytime sleep is lighter and does not fulfill the body’s sleep requirements. He explained, “This fact is supported by numerous studies of night shift workers, who are predisposed to stress, obesity, cognitive deficits, and an elevated risk of neurodegenerative diseases.”

The neurologist pointed out that the glymphatic system, responsible for clearing the brain of protein waste products, is most active during sleep. Therefore, when there is a lack of sleep, the glymphatic system may fail, increasing the risk of dementia. Dr. Sudhir stated, “Glymphatic failure is the common pathway of dementia, leading to the accumulation of abnormal proteins in the brain.”

Factors such as poor sleep quality, age, sedentary lifestyle, cardiovascular diseases, obesity, sleep apnoea, circadian misalignment, substance abuse, and depression can also suppress or result in the failure of the glymphatic system. Dr. Sudhir emphasized, “Good sleepers tend to live longer, weigh less, have a reduced incidence of psychiatric disorders, and maintain cognitive function for longer periods.”

In conclusion, Dr. Sudhir advised that consistently sleeping well at night can lead to better cognitive function and decrease the risk of dementia and psychiatric disorders. It is essential to prioritize quality sleep to maintain overall brain health and reduce the risk of neurodegenerative diseases.
