Is it dangerous to breathe hot air?

I use a television connected via HDMI on my laptop (because the screen is broken) as a monitor. To see it I have to partially close the laptop as shown in the picture.

The problem is that there are fans under the screen and the hot air goes straight into my face.

I breathe this hot air.

Dangerous?

Not dangerous, but can dry out the mucous membranes and be uncomfortable. I think it can also increase the likelihood of a cold

It's just as dangerous as walking outside the door in summer at 25 degrees and breathing the hot air

The air will be quite dry, so you are more likely to get thirsty and / or a dry throat.
If you are sensitive to drafts, you are more likely to get a sore throat.
But otherwise I don't see why that should be dangerous.

What do you do in summer at 35 °? To hold breath?

Nothing happens there - if necessary, you have to drink more because the mucous membranes become dry, but otherwise… What can be stupid is the draft, but it does not matter whether it is cool or warm.

An external keyboard may help so that you can put the laptop on the side.

Theoretically, it could be that your concentration drops a little because warm air contains less oxygen for the same volume.
