Getting an extra couple of minutes of sleep in the morning by hitting the snooze button seems like a good idea but doctors are saying, 'Don’t use the snooze.'  Some people hit the snooze button 3 or 4 times in the morning giving them and ‘extra’ 15 or 20 minutes of sleep, or so they think.  Sleep expert Dr. Neil Stanley explains like this; ‘If you hit the snooze button you may go back into a deep sleep and you’re not supposed to wake up from a deep sleep, you’re supposed to pass to the lighter preparation stage first, then you open your eyes. So snoozing creates a huge shock to the body and it makes you feel awful’.

The best thing to do is set your alarm clock 15 or 20 minutes later instead of using the snooze button, and get up when the alarm rings. The body likes rhythm so going to bed and getting up at the same time every day, creating a regular bed time, is best. If your body tells you you’re tired, don’t fight it because it could lead to bad sleeping habits.

If you use the snooze trying setting it only one time and work down from there.
