Why Sleep Needs Change with Age
As we age, our sleep architecture changes. Children and teenagers need more sleep because their bodies and brains are still developing. Growth hormone is primarily released during deep sleep, making adequate rest crucial for physical development.
Adults typically need 7-9 hours, though this varies by individual. Some people function well on 7 hours, while others need 9 to feel their best. The key is consistency and quality.
Seniors often experience changes in sleep patterns, including earlier bedtimes, more nighttime awakenings, and less deep sleep. While the need for sleep doesn't decrease significantly, the ability to get consolidated sleep may change.
