Many people have heard the general recommendation that adults should get 7 to 9 hours of sleep each night. While this guideline is a helpful starting point, sleep needs are not exactly the same for everyone.
The amount of sleep you need depends on many factors, including your age, activity level, health status, stress levels, work demands, and daily habits. Someone training for a marathon may need more sleep than someone with a sedentary lifestyle. A new parent may struggle with sleep quantity due to nighttime awakenings, while a person recovering from illness may require additional rest.
Sleep recommendations are not one-size-fits-all. Understanding how lifestyle affects sleep needs can help you determine what amount of rest allows you to feel and function at your best.
