“Usually products that you put under your tongue are absorbed quicker because that area of your mouth is very viscous,” explained Dr. Breus, “as opposed to pill that you swallow that has to be broken down in your stomach, where you stomach acid will eat up half of it.” This gives it an edge over chewable tablets or gummies, which both have to be chewed and swallowed.
Even a hint of dim light—8 to 10 lux—has been shown to delay the release of nighttime melatonin in humans. The feeblest of bedside lamps pumps out twice as much: anywhere from 20 to 80 lux. A subtly lit living room, where most people reside in the hours before bed, will hum at around 200 lux. Despite being just 1 to 2 percent of the strength of daylight, this ambient level of incandescent home lighting can have 50 percent of the melatonin-suppressing influence within the brain.
Reading books on electronic devices before bedtime disrupts the body’s natural sleep rhythms, according to research published in the Proceedings of the National Academy of Sciences. In the study, 12 people read a book on an electronic device for 4 hours before bed, in a dimly lit room, for 5 consecutive nights. On another 5 nights, they read a real printed book on the same schedule. When using an electronic device, they were less drowsy, took longer to fall asleep, and were less alert in the morning. According to the researchers, use of electronic devices suppressed melatonin levels, making it more difficult to get a good night’s rest.

Try “belly breathing.” Controlled, deep breathing is simply a way to direct your mind away from thoughts that might keep you awake. If you find your mind racing as you lie down to go to sleep, place a hand on your belly and breathe in deeply through your nose — so deeply that can feel the air filling your abdomen. Hold it for a couple of seconds, and then breathe out through your mouth. Breathe mindfully like this for a few minutes, just trying to focus your attention on the rising and falling of your belly as you inhale and exhale. If your mind starts to wander, just bring it back to your breathing. The more often you practice this relaxation technique, the easier and more effective it will be.
