As people age, achieving restful sleep becomes more difficult due to factors like stress, changes in sleep structure, and hormonal fluctuations, with 40% to 70% of those aged 65 and older experiencing chronic sleep problems. Sleep psychologist Shelby Harris highlighted that decreased sleep depth and increased prevalence of sleep disorders such as insomnia contribute to these challenges, while hormonal changes can lead to frequent nighttime awakenings. Addressing these issues through lifestyle changes and medical interventions can help improve sleep quality for older adults.
