That's why Chinese kids are always sick. I see kids for whole Summers with running noses and coughing.
The sweat lowers the core temperature and thus makes you prone to getting sick.
It's maybe cultural, but it's retarded. I actually once got fired for refusing to let my students put on 5 layers of clothes in hot May weather.
I had to sign a contract appendix to protect the kids and keep them healthy, but when retarded superstitious believes come into play, the brain switches off, and contracts are voided. Protecting from getting sick sure, but not if means dressing less....lol
Good thing is we had parent that were in the military and one hobby athlete, who disagreed with the dumb-clothing layer retardation.
I have no empathy for the dumb parents but I feel bad for the kids.
When people come to us and our kid, and give us a speech, I usually tell them, that my kid is able to be active while their kids are lying there like a vegetable, unable to move in the heat.
I tell them why we do this, they pretend to care, I tell them this way they won't get sick that often, are happier and more responsive, they sweat less and thus keep hydrated much better, as you can see by the skin of the kid.
They usually nod, think I am crazy and leave laughing, at how stupid and silly we are, and strafe of to the next hospital to buy Chinese [useless] flu medz for 600RMB.
Ah,.... we foreign devils,....aren't we a funny bunch...lol
