If you have trouble falling asleep, it is recommended that you start a regular sleeping schedule which includes waking up and falling asleep around the same time every day. Regular exercise during the day and avoiding caffeine, nicotine, and alcohol may also aid in regulating your sleeping schedule. Once you are prepared to sleep, you can try sleeping in a cool, quiet room with minimal artificial light. You can also partake in activities that will help you relax. For example, meditating, reading a book, or setting up a white noise machine may help you wind down and reduce stress.
