You should use warm water when you're washing your hands.
- sublinear 16d agoWhy? I'm already upset enough about what the water heater water is doing to my skin and am about to go tankless under my bathroom sink! That's by far the more practical option anyway if we truly cared about the problem instead of fawning over engineer porn. The problem is solved. This is pointless engagement about temperature preference masquerading as something more interesting.
- mkmk 16d agoSolubility is a function of temperature.
- maxerickson 16d agoIt used to be public health recommendation (bathrooms in commercial buildings will often only have warm water, for example, because code required it). There's been studies demonstrating that soap is what matters.
- IAmBroom 16d agoThe comment after yours, about solubility, casts serious doubt on those studies. Physics isn't changed by a faucet.
- maxerickson 16d agoI mean, no it doesn't, first principles aren't worth more than actual outcomes.
- _ah 16d agoSoap and friction do the work. But people are generally willing to wash for a longer period of time if the water temperature is comfortable.
- autoexec 15d agoAnyone who has handwashed many dishes could tell you that cold water will work, but hot water works faster and with less effort. It's no different for your hands. For best results use hot water to wash your hands and cold water to rinse them then put some lotion on them if you worry about them drying out.
