Is it true that hot baths or showers are not good for anyone?
No, espcially not hot showers, they aren’t bad ofr you unless you are actually burnt by them. Your bf is probably thinking of advice given to blokes (apparently TRUE) that hot baths damage sperm. Sperm need a very specific temperature to be healthy, and this is below body temperature (36 degree C), hence they’re kept in sacks outside the body (ok, commonly called balls). Men who take too many hot baths are at risk of damaging sperm (temporarily, they make pllllenty more). Eggs on the other had, less fussy, quite happy at body temperature and no known to complain about hot baths. Dry skin is not a longterm health problem, and can be ameliorated by a little moisturises (it DOESN’T wrinkle you). Lots of younger women get very cold, especially extremities (fingers and toes) in the winter – it may be Raynauds Syndrome (google it), it is harmless and most people grow out of it with age. Keep your fingers warm and if you smoke then try and quit, or don’t do it outside in cold weather.
