Why Does Sleep Age with Us?
A 80-year-old man has been afraid of nightfall for the past 8 years. For many years, he has experienced only 2 to 3 hours of confused sleep each night, accompanied by frequent nightmares. Due to poor rest, he has long suffered from dizziness, fatigue, loss of appetite, and emotional instability, now showing symptoms of elderly depression. Despite continuous use of sedatives and hypnotics, results remain unsatisfactory.
Research shows that most people aged 70 to 80 spend only 5% to 7% of their total sleep time in deep sleep, while young adults around age 30 spend 20% to 25%. Elderly people mostly experience light sleep, which reflects bodily aging in sleep patterns. We need not overly worry or stress about this, as excessive anxiety may worsen insomnia.
The causes of sleep aging in the elderly are multifactorial, commonly seen in introverted, lonely, inactive, and unthinking individuals. Secondarily, it is associated with increased nocturnal urination and snoring. Therefore, to delay and reduce sleep aging, one must consistently engage in activities within one’s physical capacity; avoid stimulating activities before bedtime, appropriately reduce fluid intake, take a warm bath, or soak feet. Relying on medication for sleep is not a sustainable solution.
