Naturally lengthening telomeres in humans is still a subject of ongoing research, and there are no proven methods to directly lengthen telomeres outside of experimental environments. However, some studies suggest that healthy lifestyle habits, such as regular physical activity, maintaining a balanced diet high in antioxidants, managing stress, and ensuring adequate sleep, may help reduce the rate at which telomeres shorten. These habits may help maintain telomere length over time and protect against excessive telomere loss.
