A hug is a physical gesture where one person wraps their arms around another person, typically as a sign of affection, comfort, or support. Hugs can vary in duration and intensity, ranging from a brief embrace to a longer, more heartfelt hold. They are often exchanged during moments of joy, sadness, or celebration, serving as a way to connect emotionally. Research suggests that hugs can have positive effects on mental and physical health. They may reduce stress, lower blood pressure, and release oxytocin, a hormone associated with bonding and trust. Hugs are common in many cultures and can strengthen relationships between friends, family, and romantic partners.
