Previous generations tended to blame winter illnesses on exposure to the cold. Now we know it’s typically the recirculated air in closed indoor spaces that spreads viruses and bacterial infections and aggravates allergies.
Active play is essential for children’s muscular development, and physical activity boosts the immune system. Time spent outdoors in the fresh air also helps children develop stronger autoimmune systems and resistance to allergies.
The American Academy of Pediatrics provides practical advice to parents on keeping kids safe in the cold weather. They stress the importance of dry, breathable layers of clothing, along with warm hats and mittens or gloves.
