Ask for a nonsmoking room.
Remove feather pillows and ask for synthetic, nonallergenic pillows -- or bring your own plastic pillow cover from home.

Eat in smoke-free restaurants.
For food allergies, avoid the foods that cause your allergy symptoms by carefully reading ingredient labels and asking about the food preparation methods when dining out. Choose fresh foods rather than prepared or processed foods. If you have severe reactions, such as anaphylaxis, ask your doctor about an epinephrine injection kit that you can carry at all times. Ask how many kits you should have and where they should be kept.
