Stay positive
Negative emotions can harm our bodies. And “serious, sustained stress or fear can alter biological systems in a way that, over time, adds up to ‘wear and tear’ and, eventually, illnesses such as heart disease, stroke, and diabetes,” says Sara Rimer in her article on the biology of emotion from the Harvard T. H. Chan School of Public Health. So to take care of your body, mind, and heart, try to stay positive even when life gets tough.
