<bot>: One way to help prevent your child from developing asthma is to make sure they get plenty of exercise. Encourage them to participate in sports and other activities that involve physical activity. Additionally, limit the amount of time spent indoors, especially during cold or dry air conditions. Make sure your child's home is free from dust and smoke, as these can trigger symptoms. Lastly, encourage good hygiene habits such as washing hands regularly and avoiding secondhand smoke.
