随着冬季的来临，万物凋零，许多人开始感受到情绪低落。近日，两位国外心理学专家撰文指出，冬季对人体的影响远不止于此。当人体切换到“冬季模式”时，多个器官都将面临考验。
首先，冬季寒冷的气候会影响人体的生理机能。为了保持体温，人体会自我调整，进入一种“节能模式”。这一模式会使人体血液循环减缓，代谢率降低，从而导致身体各器官的功能受到影响。
其次，冬季阳光稀少，导致人们接触到的自然光减少。这会影响人体的生物钟，导致情绪波动，容易感到疲劳和情绪低落。这种现象被称为季节性情感障碍（SAD），影响了很多人。
为了顺利度过寒冬，专家建议我们尽量保持规律的作息时间，充足的睡眠，以及适当的户外活动。这些举措有助于人体保持健康，减轻冬季带来的不适。

As winter approaches, countless people begin to feel down and depressed. Recently, two foreign psychology experts have pointed out that the impact of winter on the human body is far greater than expected. When the human body switches to “winter mode,” multiple organs are put to the test.
Firstly, the cold weather in winter affects the physiological functions of the human body. In order to maintain body temperature, the body naturally adjusts to enter a “energy-saving mode.” This mode slows down blood circulation, reduces metabolic rate, and affects the function of various organs.
Secondly, the lack of sunlight in winter leads to a decrease in natural light exposure. This disrupts the human circadian rhythm and causes mood swings, fatigue, and depression. This phenomenon is known as seasonal affective disorder (SAD), which affects many people.
To successfully navigate the cold winter months, experts recommend maintaining a regular lifestyle, getting enough sleep, and engaging in appropriate outdoor activities. These measures can help the human body stay healthy and alleviate the discomfort brought on by winter.
