From a lazy search, the measures are to trigger a reaction, but not intense enough send you to hospital. Fasted state (first thing in morning) can enhance absorption and avoid interference with food. (hot) showers cause vasodilation and exercise causes increased heart rate, both which increase allergen absorption enough trigger adverse reaction. If you have taken it for a year, your doctor may probably not worry about a too-intense reaction.
