Take a nice warm bath or shower in the evening. As well as relaxing you, afterwards your body will cool down, which helps you sleep better. Putting on lotion after will help your skin be moisturized and warm.
Reduce your light exposure an hour or two before going to bed. Bright light before bedtime can disrupt your body's internal clock. It's one of the primary clues to the body that it's either sleep time, or waking time.
If your home is brightly lit late at night, turn off lights you do not need.
Stop watching TV and using your tablet or phone at least two hours before bedtime too. It is recommended to install 'f.lux' onto your computer, which stops blue light from the screen damaging your sleep
Eliminate all sources of light in your bedroom. This includes windows, LED clocks, computer lights, cable boxes, and other devices with lights (unless they're very dim). You can cover them with heavy paper, cloth covers, masking tape, or just unplug them. Not only will you get a good night's sleep, you'll save electricity.
If light still disturbs you or wakes you in in the morning, wear an eye mask. Sometimes lavender eye "pillows" can be more relaxing.
Exercise regularly. If you have a sedentary job, a lack of physical exertion may contribute to reducing the quality of your sleep. The human body uses sleep to repair and recover. If there isn't much from which to recover, your body's sleep cycle could be disrupted.
Physical exertion (such as going for a run or a swim, or better yet, exercising regularly) can make for deeper and more restful sleep. To add more exercise to your day, take the stairs instead of the elevator, walk instead of catching the bus, and so forth.
Don't exercise less than 2 hours before bedtime. Exercise can greatly enhance and promote sleep. However, your body will be "revved up" some time after your workout. (The one possible exception may be gentle yoga).
If you happen you lack motivation for that i suggest checking out a project called lympo.io . You can get payed for working out isn't it awesome?
