Block out noise
Or better yet, eliminate it. Even if you fall back to sleep after noise wakes you, the quality of your sleep can be compromised. Turn off radios, televisions or stereos in the bedroom (and other rooms as well). If you can't control the noise, try earplugs. Design your bedroom to be a peaceful sanctuary in your home. Separate your work from the bedroom area so your body knows the bedroom is a place to rest - not work.
