For educational purposes only
This guide is educational information about stress, burnout, and everyday wellbeing — it is not medical or mental-health advice, diagnosis, or treatment, and it is not a substitute for care from a qualified professional. The relaxation, breathing, and mindfulness practices here are general wellbeing techniques, not therapy or a cure for any condition. If stress, burnout, anxiety, or low mood feel persistent or overwhelming, please talk to a doctor or mental-health professional. Breathing and relaxation exercises are generally safe — stop if you feel light-headed or unwell. If you are in crisis or thinking of harming yourself, contact a professional or call or text 988 (US Suicide & Crisis Lifeline); in an emergency, call 911.
