让你看起来巨显老的5个习惯，很多人天天都在做，尤其第3个

Core Viewpoint - A recent study identifies five unhealthy habits that significantly accelerate facial aging, making individuals appear older than their peers. These habits include smoking, lack of exercise, neglecting sun protection, unhealthy diet, and poor sleep quality [1][2]. Summary by Categories Unhealthy Habits Leading to Aging - Smoking is identified as the primary culprit of accelerated facial aging, having the most significant impact among all lifestyle habits [2]. - Lack of physical activity increases the risk of facial aging, particularly in women [2]. - Neglecting sun protection can lead to an average facial aging increase of approximately 29% compared to those who practice sun protection, with women being more affected [2][3]. - An unhealthy diet, characterized by high salt and sugar intake and low fruit and vegetable consumption, can accelerate facial aging by about 20% [3]. - Poor sleep habits, including insufficient or excessive sleep, can make the face appear nearly 20% older [4]. Recommendations to Combat Aging - Quitting smoking and avoiding secondhand smoke is crucial, as smoking damages collagen and elastin in the skin, leading to premature aging [6]. - Establishing a regular exercise routine is recommended, with a target of 150 minutes of moderate-intensity activity per week, along with strength training to combat muscle loss [7]. - Daily sun protection is emphasized as a cost-effective anti-aging measure, including wearing protective clothing and using sunscreen with SPF30 or higher [8]. - Improving diet by cooking at home and incorporating a variety of colorful fruits and vegetables can enhance skin health and reduce aging [9]. - Maintaining good sleep hygiene is essential for skin repair, including creating a dark sleeping environment and minimizing electronic device usage before bed [10].
