As people age, they experience a decrease in the amount of deep sleep they get each night. This is due to changes in brain wave activity and a decrease in the production of growth hormone, which plays a role in deep sleep. Studies have shown that individuals over the age of 60 spend roughly half as much time in deep sleep as they did when they were 20 years old.
