Getting enough quality sleep is crucial for overall health, including preventing the progression of Alzheimer’s disease. A recent study found that not spending sufficient time in deep stages of sleep – slow-wave and rapid eye movement (REM) sleep – may hasten brain deterioration associated with Alzheimer’s.
Experts say adults should aim to spend 20-25% of their night in deep sleep and 50% in REM sleep. As we age, deeper stages of sleep decrease, making it harder to achieve sufficient rest. However, establishing good sleep habits can pay off: a February 2023 study found that good sleep added nearly five years to men’s life expectancy and almost two and a half years to women’s.
To improve sleep, experts recommend creating an optimal sleep environment, avoiding booze before bed, and setting up a relaxing bedtime routine. It’s also essential to go to bed at the same time each night and wake up at the same time each morning, even on weekends and holidays. Additionally, minimizing distractions and blue lights before bed can help.
By prioritizing sleep and establishing healthy habits, individuals can potentially slow the progression of Alzheimer’s disease. Experts stress that there is no single “magic” solution but rather a combination of lifestyle changes that can lead to better overall well-being.
