I use the ibuprofen/acetominophin trick sometimes. But I already had a doctor tell me it was OK for me, as well as giving me the appropriate dosage for my size. So I don’t “recommend” others do anything.
I use a pillow for my laptop, so it’s not on my lap. You can also buy special-built cooling pads for underneath the laptop. I find the pillow puts the laptop at the right height so I can read in my lazy-boy recliner with my elbows on the armrests. And I don’t get too hot. You do need a pillow small enough that it doesn’t block the fan if it’s on the bottom of your laptop.
Both of your comments are sensible, IMO.
I learned about the ibuprofen/acetominophin trick when I asked an RN why acetominophin was in the codiene+ painkillers, because my experience had been that acetominophin did little to nothing for pain. That was when she told me how to use them.
Dosage is absolutely to be prescribed by someone who knows what they are talking about relative to each individual.
Only a kid, IMO, would be using a laptop on bare thighs. In many online videos, I have noticed young people wearing shorts almost every month of the year in every situation. I suppose it is fashion.
I do think one can use the Thermacare heat wraps against bare skin. I have, with no ill effects. They work via oxidation and it is a very low level of heat. I also will move the back heat belts around every once in awhile to catch a different area.
