What can exacerbate asthma symptoms in children?

Cold weather can exacerbate asthma symptoms in children due to a number of factors. When temperatures drop, the air can become dry and cold, which may irritate the airways. This reaction can lead to bronchoconstriction—where the muscles around the airways tighten—making it harder for a child to breathe. Cold air can also cause increased mucus production and swelling in the airways, further intensifying asthma symptoms.

In addition, many children may exercise outdoors during cold weather, which can also trigger asthma attacks as the cold air is inhaled deeply into the lungs. Therefore, it is crucial for parents and caregivers to be aware of the potential for cold weather to worsen asthma symptoms and to take appropriate precautions, such as ensuring children wear masks or scarves over their mouths when playing outside in low temperatures.
