13 hours sleep per day?
The average recommended sleep time for a 43-year-old woman is around 7-9 hours per night. However, individual sleep needs can vary, so it is important to listen to your body and adjust accordingly based on how you feel throughout the day.
An average of 8 hours sleep per night is a reasonable amount of sleep.
The average adult should be getting 7 to 8 hours sleep regularly for good health.
8 to 10
7-8 hours is optimum
I have read that the average person eats about 12 spiders per year in their sleep.
well a woman can have 12 periods a year so count that with how many years an average woman lives
7-9 hours
8-9 hours
An average on 7 to 8 hours a day.
if you mean how many hours you should sleep in a year it would be 3,650 hours of sleep for a regular year not a leap year
