1- Stressing Out
These days, researchers are sounding the alarm about just how destructive constant stress is to our bodies: It increases the risk of heart disease, high blood pressure and other chronic illnesses. What’s more, stress can actually age us on the cellular level. Harvard Medical School reports that chronic stress seems to shorten telomeres, the structures inside each of our cells that house DNA. Telomeres start out long and get shorter; when they get too short, a cell eventually dies. Not only is this the literal process of aging, people with shorter telomeres are at risk of serious diseases like heart problems and cancer.
