Ireland already has the fourth highest incidence of asthma in the world and allergies are rising fast. Alarmingly things may be getting worse: recently the World Health Organisation has found that as many as third of Irish children now have asthma.
Condensation is the formation of liquid water from air when the temperature of the air reaches its dew point. This is most lightly to occur during winter months when the walls are cold and the internal air is warm especially in locations where the relative humidity of the internal air is high. Bathrooms and kitchens are common locations where this occurs, but also bedrooms in the early hours of the morning.
