Though 7 hours of sleep is the recommended amount for most healthy adults, individual needs can vary significantly due to age, lifestyle and health. Consequently, some individuals may require closer to 9 hours or even less than the standard recommendation.

Different age groups have distinct sleep duration preferences and patterns. Newborns require up to 17 hours of sleep daily, whereas teenagers typically need 8-10 hours; meanwhile, as adults age, their desired sleep times tend to diminish gradually. As people enter adulthood, their preferred sleep times tend to decrease gradually. Older adults might experience a decline in their sleep efficiency, leading them to spend more time awake during nighttime or requiring naps throughout the day.

Impact of lifestyle factors

Lifestyle choices can significantly influence an individual's nightly sleep needs. Those who engage in regular physical activity may find themselves needing more rest due to increased energy expenditure and muscle recovery demands. Additionally, high-stress levels can lead to disrupted sleeping patterns or difficulty falling asleep at night—resulting in feeling tired despite getting sufficient rest. Furthermore, certain medications can affect both your ability to fall asleep and maintain quality slumber throughout the night.

To better understand your unique biological sleep requirements, consider tracking your personal habits using a journal or app like RISE (iOS | Android). To optimize your sleep, tracking personal habits and observing how you feel during the day are both key components for understanding your unique biological needs.
