Why do some people wake up during their sleep for 3 minutes then go back to sleep?

as humans in the old days humans naturally we woke up at about 2-5 am for about an hour then went to bed but as time went on its now know as we should sleep through the whole night but we do wake up at night every hour for about a minute but we don't know or rember this we also stop breathing for 10seconds before waking up you might be sleepwalking hope this has helped

Although, most of the sleep related problems are easy to treat. You need not worry a lot try some relaxing exercises before going to sleep. You may listen to some good music to that before going to bed your mind is relaxed.

These are slight disruptions that occur because we think upon various issues just before going to bed.

It probably happens more then that, you can get a sleep study. Usually its because your having problems breathing believe it or not. See your Primary Care giver.
