Stress Affects Rosacea

Stress can activate a condition called rosacea, which causes red veins on the cheeks or around the nose. These are sometimes accompanied by a hot or burning sensation. "Stress triggers blood vessels to dilate - and in rosacea where the blood vessels are already overly large, this can cause an attack," explains dermatologist Dr Mervyn Patterson.
Apart from reducing stress - which goes for all the conditions here - avoiding alcohol and spicy foods, which also dilate blood vessels, can help reduce rosacea.
