Why?

[Caran]

Why do people have a bath before going to bed? I think you need a bath or shower in the morning. What do you think?

baths are relaxing, and that helps some people sleep

If you get yourself clean at night you shouldn't need to do it again in the morning.

I wash at night and shower in the morning. I don't find baths at all relaxing. I wouldn't feel at all fresh and clean for the day if I didn't have a morning shower and I don't think I am sweaty and smelly when I go to bed!!

Maybe people theses days dont have time in the morning, as everybody seems to be in a rush to get to work, school run etc.

It depends what I have got planned for the day. When I was at work, I showered before going to work and maybe again when i got home (some people's homes were definitely not sanitary!)
Now I am retired, if my day is going to be spent in clean pursuits, I may well shower first thing but if I am planning to do DIY or garden or work around the house then I will shower at the end of the day.
