Is your daily nap doing more harm than good?

Naps can be healthy for adults who need to catch up on sleep or work odd hours, but they can also make it more difficult to sleep at night and be a sign of a sleep disorder. Naps should be short and limited to the early afternoon to prevent them from interfering with nighttime sleep. People who have the urge to nap daily should consider whether they need to improve their nighttime sleep habits.
