Control Your Sleep Environment to Balance Your Circadian Rhythm

Choose a Gentle Chime Alarm Clock

View your sleeping environment and decide what you can control. Awakening can be triggered by external cues such as light and sound; hence the effectiveness of the alarm clock. These triggers can override the circadian rhythm.

Light: Your mind will respond to light and bring you out of sleep. Leave your curtains or blinds open to wake up with the sunrise. Close them if you need to sleep later. Adjust the positioning of your bed to catch the light at the right time—you may need to move your bed occasionally since the sun will strike your room at a slightly different angle as the seasons progress. If you are camping, locate your tent so that the sun will hit it unobstructed (make sure there are no trees, hills, etc. that will prevent the sun from hitting your tent early in the morning). Remember that the sun rises in the east; in the northern hemisphere a south-facing orientation will receive more sunlight, and in the southern hemisphere a north-facing orientation will get more, but unless you are trying to wake up when the sun is high in the sky, you will still want to face to the east to catch the sun when it rises. As stated earlier, the position of your bed will depend heavily on the time of the year, and the time you want to wake up. If you need to get up before the sun rises, putting the lights in your room on a timer can also help, as this may not seem as disruptive as an alarm clock. Or better yet, choose a gentle, soothing way to wake up like using a Zen Chime Alarm Clock. When the clock’s alarm is triggered, the acoustic chime bar is struck just once … 3-1/2 minutes later it strikes again … chime strikes become more frequent over 10 minutes … eventually striking every 5 seconds until shut off.

Sound: Noises (such as that pesky alarm) also bring you out of sleep. Identify what sounds regularly occur around where you sleep—and when they occur. Trains, automobiles, animals, and other people going about regular tasks can serve as waking cues. You can take advantage of this by noting what wakes you up and when. Consider leaving your window open to capture more sounds.
Temperature: Your sleeping body is very sensitive to temperature. If you turn your heat down at night and have a timer on your thermostat, you can set the heat to come back on about an hour before you want to wake up. Assuming you were at a comfortable sleeping temperature all night, this should prompt you to awaken. You can also use temperature in conjunction with light, since sunlight hitting your bed directly will warm you up. You may even be able to choose what blankets you use so that you will be comfortable throughout the night (your body temperature drops after midnight), but begin to get too hot as your body temperature naturally rises (regardless of external temperature), toward the end of your sleep cycle. If you want to take a brief nap outside on a hot day (when you are camping or backpacking, for instance), you can choose someplace to sleep where you will be in a shadow initially, but where you will eventually be in the sun.

Smell: If you drink coffee regularly, the easiest way to use smell as a trigger to awake is to put your coffee maker in your bedroom and set its timer for just before when you want to wake up. Smell is not generally a reliable way to wake up, though, so use this in combination with other methods.
Feeling: Drink a tall glass of water before going to bed. You will find that you wake up very promptly.and will occasionally have to wake up and use the bathroom, so you’ll be up at least 30 minutes before target time.
