There are two big categories of sleep: REM and non-REM with all stages within these categories being important for obtaining quality sleep and feeling rested the next day. The recommended amount of sleep for adults is 7-9 hours a night. Sleep is not something that can be "made-up" as sleep lost will stay gone and you should start again the next night. Sleep is important for retaining information meaning sleep before studying is just as important as sleeping after studying. Research shows that sleep deprivation can lead to the following:
- Weakened immune system
- Increased risk of physical illnesses including heart disease and diabetes
- Irritability
- Difficulty concentrating and impaired attention
- Increased risk of mental health concerns
- Impaired memory
- Higher risk of accidents
