Sleep Disorders Among Older Adults: What Science Says

Sleep disturbances become increasingly common as people age, with changes to the body's circadian rhythm playing a central role in this shift. Medical professionals attribute these changes to natural alterations in hormone production, particularly melatonin, which regulates sleep-wake cycles.

Beyond biological factors, chronic health conditions frequently interfere with sleep quality in older adults. Conditions such as arthritis, diabetes, cardiovascular disease, and respiratory disorders can cause discomfort or breathing difficulties that prevent restful sleep. Additionally, medications commonly prescribed to manage these conditions may carry side effects that further disrupt sleep patterns.

Lifestyle factors compound these challenges. Irregular sleep schedules, reduced physical activity, caffeine consumption, and increased screen time before bedtime all contribute to sleep problems in ageing populations. Sleep apnoea, a condition where breathing temporarily stops during sleep, also becomes more prevalent with age.

Medical practitioners recommend several evidence-based approaches to improve sleep quality. Maintaining consistent sleep and wake times, creating a dark and cool sleeping environment, limiting daytime napping, and engaging in regular physical activity during daylight hours can significantly enhance sleep. Consulting healthcare providers about medication timing and exploring relaxation techniques such as meditation may also prove beneficial for older adults struggling with sleep disturbances.
