Avoid the snooze button - When you decide to sleep for just a few more minutes, your brain slips back into a state of deep sleep which makes you feel even more tired when the alarm goes off again.

Habits -

So it's best to set your alarm for the exact time that you need to get up. If you start to create a habit of always waking up at the same time, then it will get easier.

Tip 2 - As difficult as it may seem to go to bed early, try to enforce a strict bed time at the same time every night, so that your body can get used to this.

Tip 3 - Another tip has to do with the weekends. As much as you may want a lie-in on the weekends, remember that this will put your body out of sync with the routine you create for yourself during the week, meaning that it will struggle to adjust back to that come Monday morning.

Leisure time - The same thing happens when you go out late at night and drinking: your body clock is pushed out of routine.

Habits -

If you spend all night out during the weekend, then you will find it hard to get back to your routine and feel more tired when you hit the daily grind again.

Tip 4 - Before going to sleep make sure you disconnect from all electronic devices. Watching a screen for a long time will make it harder to fall asleep, and you'll wake up feeling tired.

Tip 5 - As difficult as it can be, try to be strict with the time you wake up, especially during the winter.

Winter - During winter the body usually suffers from two key things: a lack of vitamin D and changes to the time daylight appears, so it's worth keeping a strict waking and bedtime to help with this.

Activities - To finish off with, two simple tips. Firstly, avoid doing physical exercise close to bedtime, as this wakes your body up and makes it harder to get to sleep.

Medical check up -
