Aging changes
Normal body temperature does not change significantly with aging. Temperature regulation, however, is more difficult.
Because of changes in the heart, the resting heart rate may become slightly slower. It takes longer for the pulse to speed up when exercising, and longer to slow back down after exercise. The maximum heart rate reached with exercise is lowered.
Blood vessels become less elastic. The average blood pressure increases from 120/70 mm Hg to about 150/90 mm Hg and may remain slightly high even if treated. The blood vessels also respond more slowly to a change in body position.
Although lung function decreases slightly, changes are usually only in the reserve function. The rate of breathing usually does not change.
