>>11924678there are lot of folk tales that ebd up as being just folk tales
these people, ignorrant most of the times- follow anecdote after anecdote from their paremts and surroundings unaware they are based in falible pattern recognition instead of genuine fact
walking barefoot doesn't manifest rhinovirus in your respiratory trackt, however persisten cooling of the extremities causes the adverse imunodefocient reaction I talked about... however it demands entire exposition of the extremities- merely walking barefoot on room temperature tiling is impossible to cause you any ill effect aside from accidentally stepping on a sharp object
same with wet hair and going outside, it's cooling from evaporation of water that gives the imunodeficient response... however if water saturation in air is 100% then no water can evaporate/the same amount that evaporated condenses- setting the system at a net zero with no loss of temperature to the surrounding outside of simple conductivity- and given how water has a high heat capacity it xould keep you warmer for longer in this particular situation
