Can a 6-month-old baby use air conditioning in summer?

Whether a six-month-old baby can be exposed to air conditioning during summer should be determined based on the infant's health condition. If the baby is in good spirits and shows no signs of physical discomfort, using air conditioning is generally acceptable. However, if the baby has illnesses such as colds or pediatric bronchopneumonia, air conditioning should typically be avoided.

If a six-month-old baby does not show symptoms of illness—such as coughing, runny nose, or fever—and maintains normal energy levels and feeding habits, it is usually safe to use air conditioning. During hot summer months, high temperatures can pose risks to infants because their body temperature regulation centers are not yet fully developed and their sweat glands are underdeveloped, making them prone to heat rash or heatstroke.

If a six-month-old baby has a cold caused by viral infections such as respiratory syncytial virus or rhinovirus, or bacterial infections such as Haemophilus influenzae or Streptococcus pneumoniae, or develops pediatric bronchopneumonia due to weakened immune defenses from pathogens like Streptococcus pneumoniae or Mycoplasma pneumoniae—accompanied by symptoms such as coughing, fever, and nasal congestion—air conditioning should generally be avoided. Cold exposure or poor air circulation may easily aggravate the condition.
