AI Overview

Sleep quality changes with age, and older adults often experience poor sleep quality and continuity. This can be due to a number of factors, including: 

• Hormonal changes
• The body produces less growth hormone and melatonin as people age, which can lead to less deep sleep and more fragmented sleep. 
•  
• Circadian rhythms
• The circadian system and sleep homeostasis become less robust with age. 
•  
• Brain changes
• The blood-brain barrier loosens up a little at night, allowing the brain to get rid of some of the chemicals and waste that accumulate during the day. 
•  
• Other medical conditions
• Anxiety, discomfort, or pain from chronic illnesses can contribute to sleep problems. 
•  
• Environmental factors
• Air pollution can also contribute to accelerated biological aging, and sleep quality can modify the effects of air pollution on aging.
