寒冷天气对人体有什么影响？

After just 30 minutes at 10 degrees Celsius, blood flow to your brain can drop by about 20%.

人体处于10摄氏度的气温环境下30分钟后，流向大脑的血流会减少约20%。

This makes doing problem-solving tasks like studying or working much harder.

这会使人们对需要动脑筋解决问题的任务感到十分困难，如学习或工作。

Your blood pressure and heart rate will also rise, increasing the risk of a heart attack or stroke.

你的血压和心率也会上升，随之增加心脏病发作或中风的风险。

Your body will keep a steady temperature, but it's working harder and burning more energy.

你的身体会自动调节并保持稳定的体温，但与此同时需要加倍运转，消耗更多的能量。

Cold air also makes it easier for viruses to survive outside the body, and easier to catch.
