LEDs help a lot. Partly because the waste less heat but also because IR spectrum is not present in LED light.

I have worked for Canal+ a long, long time ago and I have been on the set couple of times. When the studio was lit you felt hot even though there was air conditioning.

It is basically the same as meeting sunshine on a winter day with no air movement. The air is cold but the sunshine on your skin makes you feel much hotter than it really is.
