How can I feel comfortable when I go to work on a hot day?

It depends on the specific work. If you are an office, you'd better try not to turn on the surrounding electrical appliances, and then open the window for ventilation. If it is hot, you can turn on the air conditioner and drink some green tea and mung bean soup. If you work outdoors, it is best to prepare for heatstroke prevention. There is no specific way to eat watermelon for heatstroke prevention and cooling after sorbet.
