人体研究证实，坐在窗边办公，竟能改善糖尿病的血糖控制，促进脂肪“燃烧”

Core Viewpoint - The article emphasizes the significant health benefits of natural daylight exposure in office environments, particularly for managing type 2 diabetes, as supported by recent research findings [2][3]. Group 1: Research Findings - A study published in Cell Metabolism indicates that exposure to natural light during office hours improves glucose control and whole-body substrate metabolism in type 2 diabetes patients [2][3]. - The research involved 13 type 2 diabetes patients working in two different office environments: one with natural light and the other with artificial light, maintaining consistent dietary and activity conditions [6][8]. - Results showed that patients in natural light environments had 50.9% of their time with blood glucose levels in the normal range (4.4-7.2 mmol/L), compared to 43.3% in artificial light environments, equating to nearly 2 additional hours of normal blood glucose time daily [10]. Group 2: Metabolic Changes - Natural light exposure led to a significant increase in fat oxidation rates, indicating a shift in the body's energy source from carbohydrates to fats [12]. - The study also found that participants had higher evening melatonin levels in natural light, which is crucial for regulating the sleep-wake cycle and maintaining metabolic health [15]. Group 3: Molecular Insights - Multi-omics analysis revealed that beneficial metabolites like choline, glutamate, and threonine increased in natural light conditions, while harmful lipids such as cholesterol esters and ceramides decreased, aligning with improved glucose control [17]. Group 4: Practical Implications - The findings suggest that simple environmental adjustments, such as working near windows to increase natural light exposure, could provide significant clinical benefits for type 2 diabetes and obesity patients [19][21].
