<s>[INST] My 3-year old has excessive sweating during sleeping. This does not disturb her, she sleeps well. I am afraid she d catch a cold sleeping in all wet PJ s in a dump bed for 10 hours (keep changing her PJs and sheets all night). should I be worried? and what can I do to make her sweat less? [/INST] Hi, Any other symptoms like exercise intolerance (while playing/running)? Is she gaining weight normally? Excessive sweating present only during sleeping is unlikely related to any disease, especially if she does not have any other symptoms and is gaining weight normally. Try wearing loose and minimal clothes at night(preferably cotton), and if using air conditioner, make room temperature at 25-28 deg. Take care. Hope I have answered your question. Let me know if I can assist you further.  </s>
