My most vivid sensual memory of childhood is how much I hated the cold. Getting out of bed in the cold winters of the 70s was hell. Our bedrooms weren't heated unless we were ill and there was linoleum or oil cloth or something on the floor - glossy laminate material - no rugs - and it felt like stepping out of bed into an ice rink. To immediate teeth chattering and great shivers.
I don't remember people having body odour though, except for the smell of groups of children at school after it had been raining. We didn't have baths daily always as children but it was certainly expected for adults and teens to have a daily strip wash and we had clean clothes, fresh underwear and (us children) socks daily - I remember thinking it was terrible to wear socks for two days in a row, on a very rare occasion when I had to. I would say with less heat around at home in the winter, people sweated less and their skin pores were more closed, so they probably didn't produce the amount of odour people do in centrally heated winter homes today. In summer my family did wash a lot more, you certainly kept an eye on how much you were sweating.
