Remove Distractions

• Often, people have trouble sleeping because they reserve the bedroom for everything but sleep. Your bedroom is not: an office, movie theater or any other activity that may keep you up late or cause you stress. If you are having trouble sleeping, keep your computer out of your room. Removing the television (or at least leaving it off for a while) may help.
  
  

Keep It Cool

• Our body temperatures tend to raise while we sleep, which may indicate the need to keep your bedroom thermostat lower than the rest of your home. Anything above 75 degrees F is considered too hot, and may be disruptive to sleep.
  
  

Once Upon a Mattress

• Evaluate the mattress, pillows and blankets for comfort. If your mattress is full of lumps and bumps, it may be time for a replacement. If it's not thick enough, consider purchasing a relatively inexpensive mattress pad.
  
  Is your pillow comfortable? If it's lumpy, overly hard or has lost its stuffing, it may be time to replace. Surprisingly, studies show that feather pillows may actually contain fewer allergens than synthetic pillows.
  
  

Keep Noise to a Minimum

• Even if you live where frequent noises from cars, trains or other noise-inducing properties, consider purchasing a white noise machine to block out external noise. Looking for a cheaper option? Consider an oscillating fan or earplugs.
  
  

Turn Out the Lights

• Darkness can serve as an indicator to the body that it is time to sleep. If your room lets a large amount of light in, consider purchasing room-darkening curtains. Another option is to wear a sleep mask at night to create a soothing, dark atmosphere.
