While you are asleep, your body and brain recover from the day and your immune system is strengthened. An adult needs between 6 and 9 hours’ sleep each night. If you feel rested when you get up - even if it is hard getting out of bed - then you have had enough sleep.
An occasional sleepless night causes no harm. You make up for it by sleeping more deeply the following night. Persistent insomnia, however, increases stress, reduces your ability to concentrate and, in the long-term, can cause both physical and mental health problems.
Common causes of insomnia are worry and stress - not exactly unknown among students.
Tips for good sleep
- Regular sleeping hours.
- Wind down for a few hours before bedtime (no studying!).
- Your bedroom should be dark, cool and quiet.
- Your bed should be associated with sleep, relaxation and sex – no studying in bed!
- Avoid drinks containing caffeine in the evenings.
- Exercise is good for sleep, but not just before bedtime.
- Do not go to bed if you feel wide awake and energetic.
- Alcohol can make you sleepy, but you sleep worse since your body has to work to process the alcohol.
