Either .. I wish I had a hot tub.. I don't think I'd ever get out of it. My bathtub is only big enough for a 5 year old. I'm only 5'1" and its way to short fo me. I'm like my neighbor Danielle, I can't take humid days, and I can't stay in the shower too long.
Heating pads don't last too long, because the heat brings on a hot flash. Then I'm really miserable. But when it comes to heating pads I've been told the rule of thumb is 20 mins on 20 mins off.
Hugs..
