Self-care is crucial for maintaining and improving mental health. It includes activities that nurture your physical, emotional, and psychological well-being — such as getting enough sleep, eating well, exercising, practicing mindfulness, and carving out time to relax or engage in hobbies. Self-care also means setting boundaries, saying no when necessary, and seeking social support when you need it. While self-care alone may not cure clinical mental health conditions, it provides a strong foundation that supports therapy or medication.
