Stress can worsen hives by triggering the release of histamine, intensifying itching and inflammation. Cortisol, a stress hormone, may also weaken the immune system, exacerbating skin reactions. To manage this, practice stress-reduction techniques like meditation, yoga, or deep breathing. Consult a doctor for antihistamines or, in some cases, cephalexin capsules if a bacterial infection is suspected. Avoid known triggers, maintain a healthy diet, and stay hydrated. Regular exercise can also help reduce stress. If hives persist or worsen, seek medical advice promptly to address underlying causes and prevent complications.
