Relationship between body composition, nap and night-time sleep in people aged 65 and over.

Sleep habits are strongly linked to health during whole life. However, nap habit is hardly ever considered despite it is strongly rooted in the Mediterranean lifestyle.

Otherwise, older people used to suffer from more somnolence and sleep disorders, therefore naps could be a symptom of disease instead of a healthy habit.
