Soaking in sound waves: new study tests ultrasound baths for healthier aging

This study tests whether low-frequency ultrasound baths can improve muscle strength, thinking skills, and immune health in healthy adults aged 70 and older. Twenty participants will either receive ultrasound baths three times a week for 8 weeks or sit in a bath without ultrasound. The goal is to see if this simple spa-like treatment can support healthier aging.
