Besides doing tasks such as showering or brushing your teeth, try to create a routine that also includes ways to help you get ready for the next day so that you have less to do in the morning. Try to stick to the same routine each night so that it becomes a habit. Your bedtime routine could include taking a shower, picking out your clothes for the next day, packing your lunch, and reading before falling asleep. Eating the wrong foods can give you an upset stomach or can just make it difficult for your mind to turn off and for your body to fall into a restful sleep. Eat healthy foods such as fruits, vegetables, proteins, or nuts.  Avoid drinking alcoholic or caffeinated beverages before bed. Drinks like coffee will keep you awake or prevent you from falling into a deep sleep. Eating a meal right before sleeping doesn't allow your stomach to properly digest the food, so try to eat at least 2 hours before going to bed. This means you should set your alarm so that you get the correct amount of sleep. Getting enough sleep each night will make a huge difference for how productive you are during the day, and you can’t expect to wake up early when you’re going to bed super late. For example, if your alarm needs to go off at 7 AM, start trying to go to sleep by 11 PM. The light from screens is much worse for your eyes than other types, and it will slow down your ability to fall asleep. Try to finish watching TV, using your computer, or texting at least 1 hour before it's time to sleep. It's a good idea to start a rule of no watching TV or using computers in bed. If you're a light sleeper and tend to wake up easily throughout the night, try using a noise machine or turning on a fan to create soft background noise. You can also download an app on your phone that plays white noise. If you're too hot or too cold, you're going to have trouble sleeping and won't get a good night's rest. The ideal sleeping temperature is around 65–68 °F (18–20 °C), depending on personal preferences.

Summary:
Establish a bedtime routine. Eat a healthy meal several hours before sleeping. Aim for getting 7-9 hours of sleep each night. Turn off screens at least 1 hour before bed. Play white noise to help you sleep. Set the temperature to create a good sleeping environment.
