自然光可能有助于糖尿病患者控制血糖
人体细胞和组织遵循昼夜节律,即 24 小时的代谢活动周期,这种周期调节了诸如血糖水平等生理机制。过去研究表明,夜间暴露在人造光下会扰乱这些节律,导致血糖水平升高,而多在户外晒太阳,似乎能增强身体对有助于控制血糖水平激素的反应。 研究人员招募了 13 名平均年龄为 70 岁的 2 型糖尿病患者,让他们在一个房间里待了 4.5 天。期间参与者们继续服用他们惯常的糖尿病药物,仅在每天上午 8-17 点通过大窗户接触自然光。对照实验只有人造光。结果表明,在自然光照的一周里,参与者血糖水平保持在健康范围内的时间占 50%。而在人工光照实验中,这一比例仅为 43%。研究人员认为需要进一步的研究去验证。 via Solidot

室内日光浴会加速皮肤老化
根据发表在《Science Advances》期刊上的一项研究,室内日光浴或使用人造紫外线晒黑皮肤,会加速皮肤细胞突变,可能会增加未来癌症的风险。研究人员发现,30 多岁和 40 多岁的日光浴者皮肤上的细胞突变数量比 70 多岁和 80 多岁的普通人群还要多。换句话说,从基因层面看,日光浴者的皮肤似乎老了几十岁。根据美国癌症协会的数据,皮肤癌是美国最常见的癌症,其中最致命的是黑色素瘤。每年约有 11,000 名美国人死于黑色素瘤,主要原因是暴露于紫外线辐射。紫外线辐射天然存在于阳光中,也存在于日光浴床等人工光源中。随着日光浴床使用量的增加,黑色素瘤的发病率随之上升,尤其对年轻女性造成了不成比例的影响,她们是日光浴的主要客户。许多国家已禁止使用日光浴床,世界卫生组织也将其列为一级致癌物,与烟草烟雾和石棉同属一类。 via Solidot
