There are many factors that can affect a sleeping problem from stress to an interrupted routine.
Stress is one of the biggest causes since it affects your minds ability to switch off at night.
Often you may be tossing and turning, unable to dose off to sleep because you're under pressure.
It's important to tackle the cause of the stress head on in order to then address the problems you're having sleeping.
Another cause of might be an interrupted sleeping routine.
It's important to go to bed at the same time every day, and also to wake up at the same time every day to form a routine.
It's this routine that your body quickly adapts to making it easier to sleep.
It's very difficult when you can't form a routine such as when working shifts get in the way.
At these times it's important to always aim for 8 hours uninterrupted sleep where possible.
If you are working unsociable shift hours try working out a way of either altering your body clock into a routine, or finding another job with normal hours.
Another very common cause of sleeping problems can be not enough exercise during the day.
If you're not physically active enough during the day then your body may be agitated at night.
Not allowing your body to 'let off steam' and naturally becoming active can lead to restlessness.
A brisk 20 minute walk every day - enough to get you out of breath - will work wonders on your sleeping habits.
