As people age, their sleep needs typically change, often requiring less rest. Infants need around 14-17 hours, while adults usually require 7-9 hours. Older adults may find they necessitate less sleep, but they often experience more fragmented sleep patterns. The aging process also influences the sleep cycle, potentially leading to difficulties in attaining deep sleep stages. Changes in lifestyle, health conditions, and medications further impact sleep quality and duration. Understanding these shifts is crucial for optimizing sleep hygiene and combating potential sleep disorders in the aging population.
