"People don't get sick from temperature changes." But you were used to it from being raised in such a climate. Those who are not (or lived in air conditioned houses all the time) can get serious trouble adopting. Edit: I know people who like walking bare foot, but cannot really, because they had floor heating all the time as a child. So now they get sick really fast, if their feet gets a little bit cold. I had no floor heating and I can walk barefeet in the snow (for some time. And today I like floor heating in the bathroom). My point is, be conscious how you raise your kids and live yourself. Don't make it too comfortable .. Edit2: you can train it even in the shower: switch from cold to hot a couple of times, as intense as you can manage with conscious breathing. That helps me, if I don't overdo it.
