Exercise mitigates the effects of stress - and stress, we know, shortens telomeres. In fact, early studies indicate that stress reduction techniques like meditation help people maintain the length of their telomeres.
Interpretation
Exercise and stress reduction can positively impact our cellular health.
This quote emphasizes the correlation between exercise, stress, and telomere length, highlighting the importance of physical activity and stress management for maintaining cellular health. Elizabeth Blackburn points out that not only does exercise help alleviate stress, but techniques such as meditation may also play a crucial role in preserving telomeres, which are vital for cellular aging and overall health.
In practice
In a motivational speech about health and wellness, one could quote Blackburn to emphasize the benefits of exercise.
Cancer cells have had so many other things go wrong with them, genetic, non-genetic changes, that those cells, one of the things they then get selected for is that they have lots of telomerase because now the telomeres in those cells get maintained.
We and other groups are seeing clear statistical links between telomere shortness and risk for a variety of diseases that are becoming very common, such as cardiovascular disease, diabetes and certain cancers.
Checking your telomere length is a bit like weighing yourself: you get this single number which depends on a lot of factors. Telomere length gives a sense of your underlying health.
We think there are lifestyle factors that boost telomerase naturally.
For me, arguably the story of telomeres and telomerase began thousands of years ago, in the cornfields of the Maya highlands of Central America.
If we think of our chromosomes - they carry our genetic material - as being like shoelaces, I work on the plastic tips at the end that protect them.
But the real secret to lifelong good health is actually the opposite: Let your body take care of you.
Physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity.
People with HIV are still stigmatized. The infection rates are going up. People are dying. The political response is appalling. The sadness of it, the waste.
It's not that diabetes, heart disease, and obesity runs in your family...It's that no one runs in you family!
If we are going to change our diets, we first have to relearn the art of eating, which is a question of psychology as much as nutrition. We have to find a way to want to eat what's good for us.
The poorest parts of the world are by and large the places in which one can best view the worst of medicine and not because doctors in these countries have different ideas about what constitutes modern medicine. It's the system and its limitations that are to blame.
