There may be ways to prevent insomnia from occurring or at least reduce severity and duration of symptoms:
- Counselling - people experiencing a stressful situation which is the underlying cause of the primary insomnia, may need to get a referral to a counsellor or psychologist who can help to work through the issues
- Keep blood glucose levels steady - lower than normal blood glucose levels can make a person feel very anxious and unable to get to sleep or even stay asleep. Ensure to eat enough food during the day and if necessary, have a small snack an hour or two before bed, to keep blood glucose levels maintained throughout sleep
- Reduce intake of stimulants - there are many well-known stimulants which increase risk of insomnia (caffeine, nicotine, alcohol, recreational drugs). In order to prevent secondary insomnia from these causes, it is vital to reduce intake or completely avoid them
- Regular exercise - it is important to engage in regular exercise every day, as it helps to improve mood, releases the "feel good" endorphins, exhausts energy and this may reduce incidence of insomnia symptoms from any type of insomnia
- Regulate sleep patterns - while it can be difficult, it is important to try to regulate sleep patters, to reset the internal body clock (and circadian rhythms) back to normal by going to bed and waking up at the same time each day. This can greatly help to improve insomnia, but only if done on a regular basis
