I usually use a fan or an aircon to help me overcome the situation. Also, I try to wear cottony and soft sleeveless clothes to make it more fresh. And also try to have some refresehments like a cold water, cold fresh fruit juices, ice cream or anything that is cold. Shower or swimming is also a best option.
My freezer is full with ice cream too
In times of home office I can just walk around in shorts which is awesome. Personally I keep all windows closed and lower all blinds. It's just to hot to go outside with 35 degrees, I wish i could move in the basement during summer.
I have the same thing and alos, ice cream also lightens the mood.
