According to a recent study, men aged 65+ with less deep sleep and more light sleep suffer from worse attention and processing speed. This can have an impact on the day-to-day activities (like driving) that rely on optimal attention and cognitive speed.

Researchers explain that deep sleep decreases as people age. The decreased deep sleep is related to worse cognition. That is why it is so important to pay attention to the quality of your sleep and to stimulate deep sleep to slow down brain aging.
