Thank you for your query on Healthcare Magic.
Inability to sweat is seen in skin problems like ectodermal dysplasia
in which there is absence or abnormalities of skin appendages like hair, sweat glands, and tooth.
It is a congenital problem in which the children are prone for heat pyrexia, fever
, and complications of heat exposure.
Child should be prevented heat exposure, should take plenty of oral fluids and water, and should take preventive measures while going out.
I advise you to consult the pediatrician
to manage the child problems and to know the preventive aspects.
Hope I have answered your query.
