Do fit people age slower?

Yes, fit people generally age slower both internally and externally. Regular exercise reduces inflammation throughout the body, which is a major driver of aging. Physical activity maintains muscle mass and bone density, preventing age-related decline. Fit people have better cardiovascular health, which improves circulation and oxygen delivery to all tissues, including skin. Exercise increases production of growth factors that support cell regeneration. It also helps maintain telomere length, which is linked to cellular aging. Fit individuals typically have lower stress levels and better sleep quality. Their skin often looks healthier due to improved circulation. However, excessive exercise without proper recovery can accelerate aging, so balance is important. Regular moderate exercise combined with strength training provides optimal antiaging benefits.
