Is the water warmer than the weather?
First, people's skin has different perceptions of objects.
Why do we feel cold in water at 30 degrees? This is because under normal circumstances, our body temperature is about 37.6 degrees, and water at 30 degrees is not as high as our body temperature. Of course, we will feel cold in the water. But at the same time, why do we feel busy in the weather of 30 degrees? Because people's skin has different perceptions of objects, we are very sensitive to the outside temperature, and the weather of 30 degrees has made us feel hot and dry.
Second, the water at 30 degrees in winter feels cold.
Some people argue that water at 30 degrees is not cold. That's because you put 30 degrees of water in summer. We certainly don't feel cold when we touch water of more than 30 degrees in summer, but in winter, the same water will definitely feel cold. Touching water at 30 degrees in winter will definitely make you feel cold, because the temperature outside is really too low in winter. That's why our sense of touch sends out cold signals.
It feels hot at 30 degrees in winter.
Now many places may be below 10 degrees, and even some areas are below zero. If the weather changes directly to 30 degrees, it may return to the feeling of summer. In fact, don't say that 30 degrees is warmer in winter. Even in summer, the weather in summer will make us feel bored and hot. In fact, I think there are two main reasons. The first is the nature of the season, and the second is our perception of things in different periods.
