The sleep quality theory of aging suggests that age-related changes in sleep patterns and quality can contribute to the aging process. As we age, there is often a decline in the amount and quality of sleep, including decreased deep sleep and increased awakenings during the night. Poor sleep quality has been associated with various health problems, including cognitive decline, cardiovascular disease, and impaired immune function. Optimizing sleep habits, such as maintaining a consistent sleep schedule, creating a conducive sleep environment, and practicing good sleep hygiene, can help promote healthy sleep and potentially slow down the aging process.
