One of the difficulties I have with severe COPD is becoming very short of breath when taking a shower and toweling off due to both the humid air and the activity of drying off with a towel.
I went on-line and ordered a heavy terrycloth long robe with a hood. Now when I complete my shower I slip on the robe and have a seat on the toilet and essentially dry off gently with the robe. It is much easier than briskly drying with a towel. I hang the robe on the back of the bathroom door to dry and launder it as needed.
I find it an easier way to dry off even if I wear my oxygen while showering. If you have such problems you might want to give this a try.
