Hi, my son is 4.8yrs old. He started going to school which had AC in the classrooms. Once he stepped into the school bus around 4:15 pm after school, it will be very hot outside and also in the bus (may be). So his body becomes heat very often due to heat outside. Could anyone suggest any home remedies to reduce heat as he didn’t consume enough water also. Please help me. He became very inactive today which making me feel very bad about it.
