3.Try Breathable Sleepwear
What you wear to bed can affect your body temperature. Stick with lightweight sleepwear in natural fibers. This means cotton or even — believe it or not — lightweight wool. Research shows that wearing cooler fabrics could help you fall asleep faster and stay asleep. If you find you’re still too warm, sleep in only your underwear.
4.Change Your Light Bulbs
An incandescent light bulb gives off 90% of its energy as heat, not light. A compact fluorescent light (CFL) converts 85% of its energy to light, and a light-emitting diode (LED) light is even better, putting out 90% of the energy it uses as light. Switching to a more efficient bulb will make for a cooler room and lower your energy bills too. If you do use incandescents, turn them off well before bedtime for a cooler room.
