Don't vary them by more than two hours. This may be difficult on weekends, with the temptation to sleep in, but try to stick with it. Large variations in sleep schedules can have the same effects as getting less than normal amounts of sleep.1
Your bedtime relaxing routine will help you to separate your sleep time from your daily activities that may cause you excitement, stress and anxiety.
Be sure to do these relaxing things away from bright light, and don’t do stimulating activities like homework right before bed. This can be difficult for college students to do, but try to have some downtime between studying and going to bed.
This can be difficult for students living in residence halls, but here are a few suggestions that may help:
If you try to go to bed when you’re not sleepy, you may associate your bed with feeling frustrated about not being able to fall asleep.
If you can’t fall asleep after about 15 minutes, get up and go into another room. If you are in a residence hall, get out of bed and do something non-sleep related, but that is relaxing. Return to bed only after you feel sleepy.
This may be difficult to do with only limited furniture, but try not to use your bed for doing homework or other activities that can cause you anxiety.
This will strengthen the association between your bed and sleep.
Eating or drinking too much before bed can make you feel uncomfortable as you are settling down into bed.
Try to avoid heavy meals right before bed and be cautious of spicy foods, as they can cause heartburn, which may prevent you from sleeping.
Be sure not to exercise just before bedtime, as this can actually make it harder to sleep.
Try to finish your workout at least three hours before you go to bed.
This means it causes your body to be more alert. Caffeine (found in coffee, tea, soda and chocolate) can stay in the body for an average of three to five hours.
Even if you don’t think caffeine affects you, it is likely to hinder your sleep quality. Avoiding caffeine within six to eight hours before bed can improve sleep quality.
Although many people use alcohol as a sleep aid, it actually decreases sleep quality by increasing night time awakenings. This leads to a night of lighter sleep that is less restful.
Nicotine is a stimulant, which can make it difficult to fall asleep. When smokers go to sleep, withdrawal symptoms can also cause poor sleep. Nicotine can also cause problems waking up in the morning and cause nightmares. If you are a smoker, try not to smoke within two hours of bedtime.
It is OK to take a short nap after lunch, but don’t nap longer than an hour, and never later than 2:00 or 3:00 p.m.
