Stress can have various negative effects on skin health. When a person is stressed, their body releases cortisol, a hormone that can lead to increased oil production in the skin, potentially causing acne breakouts. Stress can also impair the skin's ability to repair itself, leading to slower wound healing and a weakened skin barrier, which can result in increased sensitivity and irritation. Additionally, stress can contribute to the worsening of skin conditions such as eczema, psoriasis, and rosacea. Practicing stress-reducing activities like exercise, meditation, and proper skincare routines can help minimize the impact of stress on skin health.
