Is sleeping a lot anti-aging? Separating fact from oversleeping risks

According to the Division of Sleep Medicine at Harvard Medical School, major restorative functions like tissue repair, muscle growth, and protein synthesis occur almost exclusively during sleep. This critical process leads many to wonder: is sleeping a lot anti-aging, or is there a point of diminishing returns? The answer lies in finding the optimal duration and quality of sleep for your body's needs.

At what age does the liver stop repairing itself? The surprising truth

Despite the notion that organ function inevitably declines with age, a surprising scientific finding revealed the human liver's cells are, on average, less than three years old, even in seniors. This constant renewal means the question, "At what age does the liver stop repairing itself?", is based on a misconception about this incredibly resilient organ.

Does sleeping in the cold help with aging? Exploring the link between temperature and longevity

Research in model organisms, such as the nematode *C. elegans*, has shown that a lowered body temperature can significantly extend lifespan. This raises the question: **Does sleeping in the cold help with aging** in humans? The answer involves several intriguing biological processes, including cellular cleaning and hormone production, though the effects are complex and require balance.

Does not eating slow down aging? The science behind caloric restriction

In a landmark 2023 study published in *Nature Aging*, participants who practiced long-term calorie reduction showed a 2–3% slowing of their biological aging pace, a finding that adds substantial weight to decades of animal research. This suggests that strategically reducing food intake—a concept behind the question "Does not eating slow down aging?"—may indeed influence the aging process at a cellular and epigenetic level. However, it is a complex topic that involves more than simply going hungry, engaging cellular repair processes, and modulating gene expression.

Why does your body take longer to bounce back after 40?

By age 40, people may lose up to 8% of their muscle mass per decade, a decline that can accelerate with age. This muscle loss, known as sarcopenia, is just one piece of the puzzle explaining why your body takes longer to bounce back after 40, impacting everything from exercise recovery to healing from injuries.

Do people who fast regularly live longer? Unpacking the science of longevity

While animal studies have consistently shown that regular fasting can extend lifespan and improve healthspan, the human connection is more complex. This prompts a critical question for anyone focused on senior health: do people who fast regularly live longer? The answer involves a deeper look into the promising cellular benefits and ongoing human research.
