Why Older People Wake Up So Early

Key Points:

• Aging naturally shifts our sleep patterns, causing older adults to feel tired earlier in the evening and wake up earlier due to changes in brain responsiveness and time cue processing.
• Vision changes with age, particularly cataracts, reduce light stimulation to the brain, leading to earlier melatonin release and earlier bedtimes; cataract surgery may improve sleep quality by restoring light cues.
• Experts recommend increasing exposure to bright light in the late evening—such as outdoor walks, bright screens, or artificial lighting—to delay melatonin production and help maintain later sleep times.
• Avoiding alcohol before bed and engaging in regular exercise, along with morning sunlight exposure, can improve sleep quality and help regulate the circadian rhythm.
• While some sleep changes with aging are inevitable, adopting healthy habits can mitigate their impact and promote better rest.
