Recent research shows that both too little and too much sleep affect the ageing process of various organs in the body. Scientists investigated the sleeping habits of over half a million people and found a clear link between sleep duration and the biological age of seventeen organ systems, such as the heart, lungs and immune system.
Research shows that less than six hours or more than eight hours of sleep per night accelerates the ageing process. According to the researchers, this effect occurs because the biological clocks of these organs become disrupted. A biological clock is a kind of internal timekeeper that regulates processes in the body and is linked to health and vitality.
The study also found that the optimal sleep duration for longevity is between 6.4 and 7.8 hours per night. This is also known as the ‘longevity window’, or the sleep window most conducive to a long and healthy life. By maintaining a healthy sleep routine within these limits, people may be able to slow down the ageing process in their bodies.
Sleep turns out to be such an important factor that we can adjust ourselves in our daily lives. Because good sleep supports the functioning of many organs, it also contributes to better physical and mental health as we age. For anyone consciously engaged in healthy ageing, paying attention to a good night's rest is therefore of great importance.
