Many people over 55 know that herbal supplements can improve memory and increase energy. New research suggests that tutoring young students can have a similar benefit.

Researchers from the Washington University in St. Louis and Johns Hopkins University found that tutors in the Experience Corps program experienced significantly less depression than the control group and a smaller decline in overall physical health.

This suggests that the volunteerism could reduce age-related loss of health, according to the Washington University study.

An overwhelming number of tutors, more than 80 percent, also reported a larger network of friends, which is said to be a sign of good social health, according to the study.

Lester Strong, CEO of Experience Corps, says that “making a difference in the lives of students” keeps tutors “going – and healthy.”

Two-thirds of the least active participants also reported a sustained increase in activity levels, consistent with higher energy.

In addition to tutoring, those looking to increase energy and improve memory may consider rosemary and ginkgo biloba, herbal supplements that can lead to more vigor and increased memory.
