How much sleep do we need?
Many people are not aware that the amount of sleep we need for normal health varies with our age. Also, adults differ from person to person; for some, 4 hours a night is ample; for others, 10 hours is not enough. The average sleep for a 50-year-old is 7 hours a day.
What is a sleep problem?
There is a problem when lack of sleep or too much sleep interferes with your activities during the day. The most common cause is insomnia, which can be associated with anxiety or depression. There are other problems that can interfere with sleep, including problems of your bed mate. These problems include restless legs, sleep apnoea (brief periods of not breathing) and snoring.
