chronic stress ruins your health
The human body was not designed to be under consistent, long-term stress. If you feel daily stress and worry, your physiology actually behaves as if your life is in danger. That behaviour causes many body systems to underfunction; digestion, reproduction, immunity, detoxification, thyroid, etc. That's why chronic stress is the root cause of so many 'modern' illnesses, and puts you at risk for many diseases down the line.
You can't necessarily avoid stress, but controlling how your body responds to stress is critical if you want to achive real, lasting wellness.
You may achieve this with lifestyle modifications, supplements, nutrition, acupuncture, and specially selected herbs called Adaptogens.
