You have to optimize your sleep to improve your overall health.
Sleep in complete darkness, or as close to it as possible. Any light in the room can disrupt your internal clock and your pineal gland’s production of melatonin and serotonin. Even the tiniest glow from your clock radio could be interfering with your sleep. This will help decrease your risk of cancer. Close your bedroom door, and get rid of night-lights. Refrain from turning on any light at all during the night, even when getting up to go to the bathroom. Cover up your clock radio. Cover your windows – I recommend using blackout shades or drapes.
Keep the temperature in your bedroom no higher than 70 degrees. Many people keep their homes and particularly their upstairs bedrooms too warm. Studies show that the optimal room temperature for sleep is quite cool, between 60 to 68 degrees. Keeping your room cooler or hotter can lead to restless sleep. When you sleep, your body’s internal temperature drops to its lowest level, generally about four hours after you fall asleep. Scientists believe a cooler bedroom may, therefore, be most conducive to sleep, since it mimics your body’s natural temperature drop.
Move alarm clocks and other electrical devices away from your bed. If these devices must be used, keep them as far away from your bed as possible, preferably at least 3 feet. Remove the clock from view. It will only add to your worry when you stare at it all night… 2 a.m. …3 a.m. …4:30 a.m.
Avoid using loud alarm clocks. It is very stressful on your body to be suddenly jolted awake. If you are regularly getting enough sleep, an alarm may even be unnecessary. Try out a sun alarm clock, an alarm that combines the features of a traditional alarm clock (digital display, AM/FM radio, beeper, snooze button, etc.) with a special built-in light that gradually increases in intensity, simulating sunrise.
