A new study suggests that napping may benefit your heart by helping to
reduce the damage to the heart and arteries from high blood pressure.
Researchers examined how an afternoon nap affected blood pressure in 400
men and women with high blood pressure. Those who napped saw on
average a 5% reduction in their systolic (top) number throughout the
day. For this particular study, participants napped at midday for one
hour. Most research on napping points to the benefit of shorter naps, 20
to 30 minutes, for reducing stress, increasing alertness and
productivity, and improving memory.
