As we get older, changes to our sleep patterns occur. In fact, a normal part of the aging process is different sleep. People often report that they have trouble falling asleep and staying asleep as they age. Every night, people achieve sleep, by experiencing periods of light and deep sleep. For the most part, during sleep, our bodies remain still as our minds and body functions race to repair and reset themselves. Some of us even dream, vividly experiencing feelings and sensations all while laying perfectly still.
The trouble with achieving deep sleep
As we age, older people spend more time in the lighter stages of sleep rather than in deep sleep. People often report that they were able to fall asleep but then woke up and could not return to sleep. Our bodies need deep sleep to perform functions on just about every organ, tissue, and system. Individuals suffering from chronic illnesses, like high blood pressure and cancer, need sleep to heal and get batter. Instead, older people report that the next day after poor sleep quality their mood and ability to perform active tasks is affected by fatigue.
