Improve Memory with Exercise

Deep within our brain the hippocampus has an important role in controlling our long-term memory, emotions, and spatial navigation. In the first study of its kind, researchers in Australia and the UK examined the impact of aerobic exercise on the hippocampus in humans.

Brain scans from 737 participants were reviewed before and after an exercise program. Participants ranged from 24-76 years of age and included health people, those with mild Alzheimer’s, people with depression, and people with schizophrenia.

Exercise programs included aerobic exercise on a stationary bike, walking, or running on a treadmill 2-5 times per week for 3-24 months. 

While our brain typically shrinks about 5% per decade after the age of 40, researchers found a significant increase in the size of the left area of the hippocampus in study participants. Researchers believe physical exercise is one of the “proven” ways to maintain brain size and function as we get older.

With exercise the body produces brain-derived neurotrophic factor which appears to reduce the deterioration of the brain. Over time this may be why aerobic exercise prevents age-related mental decline.

Indirectly exercise can help you get better sleep, improve your mood, and reduce stress and anxiety; problems which can contribute to mental impairment.

Researches are optimistic regular aerobic exercise might reduce Alzheimer’s and dementia, although more research is needed to establish such benefits.
