Article: It can be hard to fall asleep at night or to sleep late in the morning if you are not getting adequate physical exercise every day, which exhausts the body and helps you rest more thoroughly at night.  If you do not regularly exercise, ease into a regular routine of about 30 minutes of moderate activity a day. This can be as simple as a walk around your neighborhood. In addition to sleeping better, there are so many benefits to regular exercise, including better immunity, emotional health, and self-confidence. Going to bed and rising at the same time every night is actually the best way to feel rested, instead of relying on sleeping in to "catch up" on lost sleep throughout the week.  Instead of sleeping in on weekends, try going to bed thirty minutes to an hour earlier than your typical bedtime during the week. Then, on weekends, go to bed and rise at the same time as you do during the week. This will add in the needed extra sleep without compromising your sleep schedule. Most adults need between 7 and 9 hours of sleep a night to feel rested and productive; children and teenagers need significantly more (anywhere from 9 to 11 hours). The exact amount varies depending on your body's needs and how active you are throughout the day. Your body's natural circadian rhythm is strongly linked to light: you are naturally wired to be alert in the daytime and to sleep at night, so light contributes to wakefulness and dark contributes to sleepiness. You need to ensure that your daytime environment, whether it's an office or your home, is full of lots of natural light to keep your circadian rhythms in balance. Open up the blinds, take heavy draperies off the windows, and turn on your lamps or other lights in your home during the day. If you can't get a lot of lights in your indoor environment, be sure to spend a lot of time outdoors in natural light. One of the biggest contributing factors to poor sleep quality is high stress levels. Learning coping techniques to lower your stress level can help you sleep better at night, so that you'll feel more rested and won't need to sleep in.    Practice positive self-talk. Research has shown that having a good attitude can actually reduce stress levels. You can begin changing your attitude by saying positive things to yourself instead of negative things throughout the day. Instead of thinking about your faults and failings, think about your strong points. Instead of saying to yourself, "I'm bound to fail" or "I always mess up," tell yourself "I can do this," and "I can handle this."  Find a creative outlet like painting, sports, music, or cooking. Expressing yourself creatively can reduce your stress and help you find pleasure in life.   Learn to relax. There are many ways to relax throughout the day and before bed; try meditation, yoga, or tai chi to see what works for you.
