6 daily habits to slow aging, from a Harvard brain expert
Tanzi's SHIELD plan promotes six habits including sleep and exercise to reduce Alzheimer's risk; a study links 1,000 steps walked to delaying the disease by one year.
- Recently, Harvard brain expert Tanzi's SHIELD recommends six daily habits emphasizing sleep, stress management, social interaction, exercise, diet, and learning to guide brain health.
- Sleep clears brain toxins, Tanzi says, and deep sleep drains amyloid toxins linked to Alzheimer's disease while chronic stress raises cortisol, accelerating cognitive decline amid modern life factors.
- A Mass General study found that walking impacts Alzheimer's risk, and each 1,000 steps roughly delays onset by one year; Tanzi uses his office exercise bike 30 minutes every other day at 80 to 90 rpm.
- Challenging the brain with new activities builds synapses and a synaptic reserve that helps prevent cognitive decline, and Tanzi composes ambient jazz while studying documentaries, books, and podcasts.
- Recently Tanzi has focused on environmental exposures beyond diet, and his next book this year will explore 'killer P's' like plastics, pollution, periodontal bacteria and processed foods.
