Ach, jesus, I'm not arguing for people to be more paranoid about normal activities.
But this thread was full of people saying there was no risk from overheating, people in hot countries are fine, yadda yadda. So what I'm saying that, while it's probably fine, it's also unfair to call it an old wive's tale, clearly. And from what I've read there IS a risk from overheating in the early stages, and different papers use different examples* of how this hyperthermia can take place. And that risk is small.
But I reckon knowledge is power. I'm not going to be reassured by people telling me it's irresponsible to read the actual research.
By the 'injunction' I should be clearer -- I meant the common advice we hear to avoid hot baths, saunas, etc etc. I don't read official NHS guidelines ever since they changed their advice on alcohol consumption based on absolutely fuck-all because, and I quote my doctor, 'lots of women don't understand what 'light drinking' is, so safest to say none'.
*That link I was trying to find out the distinction, if any, between them. Obviously, the difference between saunas, baths, jacuzzis, hot yoga etc depends on how you use all of them: fr'instance, I hate saunas and am out of them within minutes, whereas I like a two-hour v hot bath where I read a whole novel.
