Napping can be done anywhere where it’s comfortable, be it a parked car, under your desk or a chair. For some, a quiet, dark place may be necessary but for others a subway or airplane seat works just as well. One tip: If you’re trying to stick to a short nap it may help to be partially upright. Studies have found that if you lie supine you’re more apt to fall into a deeper sleep.
Catch yourself dreaming during a short power nap? That’s a sign that you’re sleep deprived because you’re quickly slipping into rapid eye movement sleep, which is supposed to be the final stage of the roughly 90-minute sleep cycle.
Try getting more sleep at night but make sure you take the poll before that.
