UnknownPositive thinking promotes mental and physical health, which also tends to improve one’s external appearance. Negative thinking increases cortisol levels, a stress hormone, and unmanaged stress may produce complications such as poor dietary and lifestyle choices, disrupted sleep, and other negative consequences. Some skin conditions are also triggered by stress including acne, eczema, and psoriasis. A positive frame of mind will decrease stress, stabilize the mind, help prevent illness by strengthening the immune system and promote healthy food and lifestyle choices, which all positively impact the outer appearance. Positive thinking also lifts the mood and encourages smiling, laughter and other pleasant expressions that are attractive.
