Improving sleep and other lifestyle factors keys to better brain health

Poor sleep is also connected to depression which can result in less physical activity and unhealthy eating habits. All these factors are interlinked and together may have an impact on dementia risk.

“Science shows that somewhere in the range of 40% of dementia cases worldwide could be delayed or even prevented with long-term lifestyle changes,” said Dr. Pruzin. These include increased physical activity, smoking cessation, staying socially engaged, quality sleep and diet. “You can give yourself the best chance at avoiding cognitive decline and dementia by addressing these lifestyle factors over decades. Unfortunately, there other factors that also matter that we don’t have control over like the genes we receive from our parents.”

Behaviors that promote better sleep are collectively known as sleep hygiene. Dr. Pruzin shared some suggestions for getting a better night’s sleep, along with ways to address other lifestyle factors. But don’t take them all on at once. Identify one area you most want to change and start there.

  • Sleep Hygiene
    • The bed is a place of rest and should only be used for sleep
    • Don’t watch television, use your cell phone or computer in bed
    • Go to sleep and wake up at about the same time every day
    • Limit caffeine and alcohol
    • Be sure you’re physically active during the day
  • Physical Activity
    • Exercise protects the brain
    • Exercise for 30 minutes or more at least five times a week
    • It doesn’t have to be intense exercise, walking is just fine
  • Diet
    • Learn more about the MIND diet. It combines food from the Mediterranean diet and the DASH diet (for blood pressure control) to focus on brain health.
      • Avoid processed foods and red meats
      • Focus on leafy greens, natural foods, nuts, berries, vegetables, olive oil, fish
  • Socialize with friends and family as much as possible
  • If you smoke, quit now.

“Over time, these changes will add up,” said Dr. Pruzin. “There is no magic bullet when it comes to lifestyle changes. It takes years to see results but, in the meantime, you’ll feel better about the changes you’re making now.”
