This is one of the most important things to consider. Good beds don't always mean "soft," so get one that provides good support to your back and make sure you are comfortable sleeping on it. Be sure to use a pillow that is comfortable and supportive for your sleeping style. Having the right pillow will ensure that you wake up feeling refreshed and pain-free. If you are comfortable, you will be more likely to sleep longer. Keep your bedroom properly ventilated so you get plenty of fresh air. Set the temperature of your room appropriately, not too warm or too cold. Typically this will be between 65 and 72 degrees Fahrenheit, but you should adjust the temperature so that you feel comfortable. Setting the temperature just slightly cooler than comfortable -- so that you're fine, but still need covers -- will help you sleep. If your room is stuffy, try cracking the window a bit before bed time. In addition to providing extra airflow and controlling room temperature, a fan produces a low, consistent level of background noise. This can help eliminate auditory stimuli that keep you from falling and staying asleep. Keep in mind that for some, a fan might not be helpful. If it doesn’t work for you, then don’t use one. Try to keep your room dark at all times. Your brain is stimulated by light signal, so keeping a dark room helps you get to sleep faster. You can help with this by installing blackout blinds or curtains  This applies even to small lights, like those on your T.V., a digital clock or D.V.D. player. The absence of light eliminates the presence stimuli that can alter or affect your sleeping patterns. If there is some reason you cannot, or do not wish to, install blinds or curtains, you can invest in a sleep mask to help simulate darkness. Check if your room is free from mosquitoes and other pests. Also, if you have pets in your home, make sure they can’t access your bed or enter your room to avoid disturbances while sleeping. There is evidence that it is easier to sleep in a fresh, clean, or nice smelling space. Try spraying your room with a mild room spray to lighten up your mood and the ambience in your bedroom. If you choose to use scented candles, be sure to put them out before falling asleep to avoid fires in the home.
Use a good, high quality mattress. Ensure your head is well supported. Ensure proper ventilation and temperature. Keep a fan running. Keep your room dark. Eliminate pests and disturbances. Use scented candles and sprays.
