Not surprisingly, then, long-term stress has been linked to anxiety, depression, digestive problems, memory loss, insomnia, hypertension, heart disease, strokes, cancer, ulcers, rheumatoid arthritis, colds, flu, aging acceleration, allergies, body pain, chronic fatigue, infertility, impotence, asthma, hormonal issues, skin rashes, hair loss, muscle spasms, and diabetes, to name just a few conditions (all of which, by the way, are the result of epigenetic changes). No organism in nature is designed to withstand the effects of long-term stress.
