It is common for people to have difficulty sleeping at times. There are many things you can try to improve your sleep quality. First, make sure that the environment in which you sleep is comfortable. Try using a mattress that supports your body and keep the temperature cool. You may also want to consider using white noise or light therapy to help you relax. Additionally, exercise regularly during the day and avoid caffeine late in the day. Finally, talk to your doctor if you're still having difficulty sleeping after trying these methods.
