Second, we capped melatonin supplements’ per-pill dosage of melatonin at 1.5 mg. While any average melatonin supplement likely contains up to 10 mg of melatonin, Dr. Michael Breus (a clinical psychologist who runs the website thesleepdoctor.com) says that’s far too much for the average person. “The data suggests that the average adult needs between 0.5 and 1.5 mg,” he says.
If your bedroom is boiling hot — or even slightly warm — do what you can to cool it down. "Warmness may make you feel sleepy, but is not conducive to deep sleep," Logie says. "Our body starts to naturally cool later in the day and keeping your room cooler can help speed up this process that's involved with you falling asleep quickly and getting that deeper sleep."
Factors that influence your sleep-wake needs include medical conditions, medications, stress, sleep environment, and what you eat and drink. Perhaps the greatest influence is the exposure to light. Specialized cells in the retinas of your eyes process light and tell the brain whether it is day or night and can advance or delay our sleep-wake cycle. Exposure to light can make it difficult to fall asleep and return to sleep when awakened.
Your bed plays one of the biggest roles in determining how long and how well you sleep. Your mattress and pillow have to be up to snuff for you to slumber well. Your bed and your body naturally change over time (they’re both aging!), so if your mattress is seven years or older, it’s probably time to replace it. Older mattresses do not provide the support you need for restful sleep and need to be replaced. Making this one improvement can unlock nights of blissful sleep. Your pillows should also be replaced regularly once a year to make sure you are getting proper support for your neck and spine.
