What is the temperature? You can wear short sleeves.

The temperature varies from place to place, from season to season and from person to person, but generally speaking, when the temperature exceeds 20 degrees, you can consider wearing short sleeves. In addition, the factors to be considered include weather factors such as humidity and wind, and people's perception of comfort.

At the same time, we should also make choices according to our own physique. For example, people who are prone to colds and skin allergies should not wear short sleeves too early.
