If you are used to going to bed at midnight, you will certainly have trouble suddenly going to bed at 8 o’clock. Instead, try going to sleep at 11 o’clock, then 10 o’clock, and so on. It can take days or weeks to change your body’s natural rhythm. It’s  important to begin adjusting your body a couple weeks before school starts. Give your body and mind plenty of time to adjust. Don’t start trying to adjust your sleep schedule two nights before school starts. You didn’t become a night owl overnight, so don’t expect to become a morning person overnight either! It takes time to reset your internal clock, so start a couple of weeks before the first day of school. Different age groups have different sleep requirements. Children from 6 to 13 should be getting 9-11 hours of sleep nightly, while teenagers ages 14-17 need about 8-10 hours. Younger adults age 18-25 are recommended to receive about 7-9 hours. Exercising regularly is a great way to expend energy and ensure you sleep soundly at night. It can also help you fall asleep more quickly. Studies have shown that people who exercise at least 150 minutes a week also feel more alert and energized during their waking hours. Exercising late at night can energize you right before you need to be in bed. Try to work out in the mornings or early afternoons, and relax with more calming hobbies in the evening, such as reading. Not only can caffeine make it harder for you to fall asleep, but it can also make your sleep disruptive and uneasy. By avoiding caffeine completely, you can get the deep, restorative sleep that will set you up for a successful day. If you don’t want to cut out caffeine  completely, at least try to avoid it up to six hours before bedtime. This means everything- phones, tablets, televisions, etc. These devices shine light into your eyes, which has been scientifically proven to promote wakefulness. Just as the sunset signals the end of the day, your electronics should go lights out too. A dark bedroom tells your brain that it is time to sleep. There are also free apps on smartphones that can provide white noise- just make sure the bright screen is off! Your brain craves stimulation, and it can be hard to turn that desire off at night. A white noise machine provides that stimulation, in a gentle and calming way. It also masks any bothersome noises from outside your bedroom that can keep you awake. You can play around with different white noise options such as thunderstorm, campfire, rain forest, and more. It is not easy to sleep if you are tossing and turning in a hot bedroom. As your body temperature lowers, your brain is told that it’s time to sleep. The best temperature for snoozing is anywhere from 60 to 68 degrees Fahrenheit.  If you aren’t in control of the thermostat, a ceiling fan or a portable fan can do the trick. A fan can also provide calming white noise.
