How much sleep do you need? A neuroscientist crunches the numbers

How much sleep is enough? You might have heard that eight hours of slumber a night is the optimal amount for every person, but in reality, how much sleep you need varies throughout your lifetime. Your age, health, daily activity levels and even your work can each impact how many hours of sleep you need.

While your age is a good indicator of how much sleep you need, take your personal circumstances into consideration too.
