According to Daily Mail, after a poll of 2000 people by a mattress manufacturer, 4 out of 5 say having sex before bed time does NOT make for a peaceful rest! To get the best night's sleep, turn your thermostat down, have the room totally dark, sleep on your right side and don't cuddle with your partner and expect a sound sleep. Spooning is fine to start, but you'll sleep better once you separate. And don't sleep naked! The comfort of pajamas makes for a more restful night.
