Can you, I don't know, drink a bunch of water before you shower, pump up the blood volume a little? Maybe water now would help, too.
One of the things I've done in the past is to leave the bathroom door open - so the steam doesn't get so problematic. I haven't had to do it since last summer tho' - the heatwave we're in right now sorta snuck up on me. And I need to drink more water. I try to be hypervigilant about this, since my allergies are so bad I take a lot of decongestants, and I've had wooziness problems in Karate, and Swing Dance, and Kung Fu. But, these last couple weeks of the semester have been so hectic that I've been letting "nutrition" slip, and that seems to include drinking enough water, apparently.
Not least because I immediately flash to all the most-accidents-happen-in-the-bathroom stats and think of everything I could hit my head on if I did keel over in the shower.
Yes, this. Although, I think I worry more "what if someone found me like this?" than the head-hitty stuff (which is really stupid considering my record for face-plants - ah, but Vanity, she is a strong one)
