Hi doctors normally people say an adult should get continuous 7 hrs of sleep without any break to continue the next day work briskly asap. I go to bed by around 10.30 pm. My sleep gets disturbed around 4.45 and further on I am unable to continue sleeping. My mind wanders about the next days schedule or past .kindly help me out what should I do to get a break free sound sleep for 7 hrs. Thanks and regards sivaraj.
