Heat rash can develop on your children’s skin when they are in hot, humid weather and when they are engaging in intense physical activity. This can affect older children as well as babies.
A heat rash often occurs when your child’s skin is not able to breathe. This may cause excessive sweating that can block pores, causing redness, irritation and itchiness.
To help cool your child’s heat rash, get them out of the heat, cool them off and remove any restrictive clothing. Do not use creams or lotions as these may further block pores.
Heat rashes normally clear up in a few days and do not do any lasting damage to skin. However, if your child has a heat rash and a fever, or if the rash is not going away, you should take your child to see a doctor.
