Colds and flu don’t just spread through contact many respiratory viruses also travel through the air in tiny droplets released when we breathe, talk, cough or sneeze.
Indoors, these airborne particles can linger for longer, especially when windows are closed and air is recirculated. This can increase the chance of viruses spreading within homes, schools and shared spaces.
Symptoms often spread more easily during colder months and at night, when ventilation is reduced and people spend longer periods together indoors.
Improving indoor air circulation and reducing the build up of airborne particles can support a healthier home environment particularly in bedrooms and family spaces.
