My friends around me feel energetic after sleeping seven or eight hours a day, but I still feel tired even after sleeping ten hours. Is the required amount of sleep different for each person?

In general, the amount of sleep each person needs varies.

The required amount of sleep differs significantly across age groups. Generally, newborns and infants require more sleep to support their growth and development, while adults need relatively less sleep, with an average recommended sleep duration of 7–9 hours per night. As people age, sleep duration may further decrease, but sleep quality remains important for the health of older adults.

In addition, lifestyle habits, genetic factors, and environmental factors can also influence sleep needs. For example, individuals who frequently stay up late or have irregular sleep schedules may disrupt normal sleep rhythms, leading to reduced sleep quality and insufficient sleep duration. A good sleep environment and comfortable bedding products, on the other hand, can help improve sleep quality and thereby better meet an individual's sleep needs.

In daily life, it is recommended to arrange sleep time reasonably according to one's own circumstances to ensure adequate rest and recovery.
