Why are there only high-temperature subsidies and no low-temperature subsidies?

In fact, there are both, but the high temperature is as hot as that in the north, so subsidies are more common. At present, low-temperature subsidies are only aimed at some people in some areas and are not universal. Why is there a high temperature subsidy? It is to ensure the normal operation of economic construction and enterprise production activities under the condition of hot summer and high temperature (above 35 degrees). June-August every year is an important measure for heatstroke prevention and cooling. When the temperature in the north and south is 38.5 degrees, it is still relatively uniform. For example, some outdoor workers can't cool down in summer, so the high-temperature subsidy is more popular, and it is also to prevent high-temperature workers from suffering from a lot of heatstroke. So, what about low-temperature subsidies? You can wear clothes when it is cold in the south, and the winter in the south is shorter. Generally, the temperature will recover in a few days after the cold wave, so there are few things that freeze people to death in the south. In the north, some countries have built very perfect heating measures, and outdoor workers in the north basically don't work in winter and don't need low-temperature subsidies. In addition to supporting protective measures, there are actually low-temperature subsidies for a very small number of people who need outdoor low-temperature work.
