How exercise can help you live longer

There are many reasons to get in shape. Weight loss is a prime motivator, as is reversing a negative health effect, such as high cholesterol or increased diabetes risk. Routine exercise also can improve life expectancy.

WebMD says exercise keeps the body and brain healthy. That’s why exercise should be an important component of daily life no matter one’s age.

Research published in the journal Immune Aging found that how people age is 75 percent lifestyle and only 25 percent genetics, which underscores the importance of the lifestyle choices people make.

Cardiorespiratory fitness

Many health experts say that cardiorespiratory fitness may be just as valuable a metric to determine overall health as blood pressure and lipid levels. People with a high aerobic capacity can deliver oxygen to tissues and cells efficiently to fuel exercise, according to data published in 2014 in the journal Aging & Disease. In a study involving 11,335 women, researchers compared V02 max, also known as aerobic capacity, in women with mortality data. Women who were fit from a cardiovascular perspective had a lower death rate from all causes, irrespective of the women’s weight.

Exercise has direct stress-busting benefits that can promote longevity. The Mayo Clinic says physical activity can increase the production of endorphins, which are the body’s feel-good neurotransmitters. In addition, exercise can imitate the effects of stress, helping the body adjust its flight or fight response accordingly, and help them cope with mildly stressful situations. While engaged in exercise, people may forget about their problems as they are focused on the activity at hand.
