Thyroid disorders, including hypothyroidism and hyperthyroidism, have become common due to genetic predisposition and external factors like stress. Stress increases cortisol and adrenaline levels, affecting thyroid function. Managing stress involves deep breathing exercises, meditation, regular exercise, healthy food, sufficient sleep, living in the present, maintaining work-life balance, and seeking professional help. Chronic stress has been shown to affect the thyroid gland in some studies.
