There are some people who must go to sleep very early in the evening and as a result wake up around 3 am in the morning. People with these hours have Advanced sleep phase syndrome. It is most common with elderly people or either women who are going through post-menopause.

Treatments for Advanced sleep phase syndrome:

- therapy
- herbal supplements
- exercise
- lifestyle change
- medications
- stimulants

Depending on how severe the case is the treatment will vary. People who have Advanced sleep phase syndrome might be lacking in a vitamin or need extra herbal supplements to help treat it. Other times it just requires a change with diet or staying off soft drinks with sugar in it. Some people who can not change their patterns with this syndrome often find ways to work around it with going to therapy lessons and taking jobs that might be late night shifts.
