Exercise may be key to slowing age-related cognitive decline, research suggests

Norway: As we grow older, cognitive abilities begin to wane. We forget names and places, lose trains of thought, and become creatures of habit. But a key to overcoming these ageing-induced deficits may be exercise, according to new research.

“Exercise improves cardiovascular fitness, glucose metabolism, insulin sensitivity, blood pressure, lipid profiles, sleep, mood, and immune function,” said Atefe Tari, a researcher studying exercise and brain health at the Norwegian University of Science and Technology and St. Olav’s University Hospital.

The link between physical activity and brain health is drawing increasing attention as populations age worldwide. While memory lapses and slower processing are common with age, researchers say lifestyle factors like regular exercise could help maintain sharper thinking for longer.

Tari’s work adds to a growing body of evidence showing that the benefits of exercise extend well beyond the body. By supporting heart health, metabolism, and sleep, physical activity may create conditions that help the brain stay resilient.

Experts say more studies are underway to determine what types, durations, and intensities of exercise offer the most protection against cognitive decline.
