The main thing is to not get in the bath while you are running it. You tend to have it alot hotter if you are in the bath with the taps running as your body temp adjusts.
my problem i end up so tiered and exhausted physically maybe to relaxed would be better said that i almost pass out i have trouble getting out of bath, i have to call hubbie and sit down for the next 30 mins with cold drink. i always bath with the bathroom door open too.
