When is the sun usually not warm in spring?

Generally speaking, it is not warm at 4-5 pm.

Sunbathing in spring is usually carried out from 9: 00 am to 1 1 pm and from 15 pm to 17 pm, which avoids the strongest time of the sun, because too strong sunlight can easily cause discomfort.

Spring, the first of the four seasons, refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. Spring represents warmth and growth. In spring, the qi of yin and yang begins to change, and everything germinates and grows with the rise of yang. As far as solar terms are concerned, spring in China begins in the beginning of spring (February 2-5) and ends in the long summer (May 5-7). In Europe and America, spring begins at the vernal equinox in China and ends at the summer solstice. In Ireland, February to April is designated as spring.
