Prolonged sleep may accelerate ageing. How many hours are ideal for seniors

Sleep is one of the most important factors in maintaining good health in later life, being essential for the body's regeneration, memory consolidation, and the elimination of accumulated toxins. However, sleep medicine specialists warn that more sleep does not always mean greater health benefits.

Recent research suggests that excessive sleep may have a negative impact on the ageing process, accelerating certain degenerative processes at a cellular level. For older adults, finding the right balance between adequate rest and avoiding prolonged sleep becomes crucial to maintaining a healthy life.

Specialists recommend that older adults aim for between 7–8 hours of sleep per night, avoiding both insomnia and regularly sleeping for more than 9 hours. Sleep quality appears to be just as important as quantity, particularly for seniors who are experiencing natural changes in their sleep cycles.

For older adults who spend too many hours in bed, the risks can include increased inflammation, a weakened immune system, and accelerated cellular ageing. Prolonged sleep may also contribute to cardiovascular problems and a decline in cognitive function.

Geriatric physicians recommend that seniors monitor their sleep patterns and consult specialists if they notice significant changes in the duration or quality of their nightly rest, in order to maximise the benefits of recovery without exceeding the optimal threshold.
