Unwelcome noise or light, an uncomfortable or worn-out mattress and foundation, or a room that's too warm or too cool can prevent you from getting the sleep you need. There's no reason to settle for anything less than perfect sleep. Be sure your mattress and foundation meet your needs for both comfort and support. If you sleep with a partner, your mattress should also allow you both enough space to move easily.
Light is one of the body's most powerful time cues.
The rising sun can wake up the brain long before the alarm goes off. Sudden, loud noises from inside or outside the home can disrupt sleep. Steady, low sounds, such as the whir of a fan or air conditioner, are soothing because they help block out distracting noises. A room that's too warm or too cool can disrupt comfortable sleep.
