Too much or too little sleep may make your body age faster
Both too little and too much sleep may be linked to faster aging throughout the body. Researchers analyzing 23 biological aging clocks found the lowest aging levels among people sleeping about 6.4 to 7.8 hours per day. Short or long sleep was also associated with numerous conditions affecting the brain, heart, lungs, metabolism, and digestive system.
A recent study examining biological aging across the human body has found that both insufficient and excessive sleep can accelerate aging in various organs, including the brain, heart, lungs, and immune system. The research, led by Junhao Wen of Columbia University Vagelos College of Physicians and Surgeons, suggests that sleep plays a crucial role in maintaining organ health within a coordinated brain-body network.
Using aging clocks, which rely on machine learning and biological information, the researchers discovered a U-shaped pattern in aging, with the lowest levels of aging observed among individuals who slept between 6.4 and 7.8 hours daily. Short sleep was linked to conditions such as depression, anxiety, obesity, type 2 diabetes, hypertension, ischemic heart disease, and heart arrhythmias, while long sleep was associated with chronic obstructive pulmonary disease, asthma, and several digestive disorders.
The findings highlight the importance of sleep in overall health and suggest that personalized sleep management could be a potential therapeutic approach.
