'Tis the season to eat, drink and be merry, but make sure you don't sniffle and sneeze your way through the holidays. Seasonal triggers, including that beautiful three-metre-high Christmas tree, can bring on allergies or allergy-like symptoms.
Take action: Have as much ventilation as possible in the rooms where you keep the tree, candles, incense or potpourri; if you put your tree in a container of water, change the water frequently; watch out for foods that may have "hidden" ingredients - wheat, eggs, milk, soy, fish or shellfish, legumes and nuts from trees, could pose a danger to guests who have allergies.
