There are two kinds of people in this world: those who believe in naps and those who don’t. Group A celebrates a minor victory today, as a new study has shown that short, midday naps not only improve alertness, but they also contribute positively to heart health. Researchers observed that an hour-long sleep at noon contributed to a significant decrease in systolic blood pressure, lowering it on average about five percent throughout the rest of the day. Naps also helped lower blood pressure during nighttime as well as the size of the heart’s left atrium and amount of arterial damage. Perhaps one day we’ll consider a noontime siesta as important as having lunch. Do you nap in the middle of the day? If so, what kinds of benefits do you feel? Share your thoughts in the comments.
