[For Seniors] Trivia Quiz & Fun Facts on Hay Fever: Learn Preventive Measures and Symptoms You Should Know (11–20)
Which of the following foods are considered good for preventing hay fever?
- chocolate
- yogurt
- French fries
See the answer
yogurt
Fermented foods like yogurt are believed to improve gut health and help prevent or alleviate hay fever by balancing the immune system. Eating them together with foods such as honey or bananas, which contain oligosaccharides that serve as food for lactic acid bacteria, can help increase those beneficial bacteria.
It’s spring, when lots of pollen is in the air, and the amount depends on the weather during a certain period of the previous year. Which period of the previous year is it?
- the spring of the previous year
- the summer of the previous year
- the winter of the year before last
See the answer
the summer of the previous year
Whether large amounts of pollen are dispersed is greatly influenced by the previous summer’s weather, especially temperature and hours of sunshine. If summer temperatures reach 30°C or higher and there are many hot, sunny days, many flower buds that produce pollen will develop, making it easier for large quantities of pollen to be released the following spring. Conversely, in summers when the maximum temperature is around 25°C, the trees focus more on extending their branches than on producing flowers, so the amount of pollen dispersed the following spring tends to be lower.
Which of the following methods will further enhance the effectiveness of using a mask to protect against pollen?
- Layer gauze on the inside of the mask
- Keep using the same mask
- Wet the outside of the mask
See the answer
Layer gauze on the inside of the mask
By layering gauze on the inside of your mask, you can further prevent the intrusion of fine pollen particles. Continuing to use the same mask is counterproductive, and wetting the outside reduces breathability, so you can’t expect it to be effective. Pollen-specific masks are also sold commercially, so why not give them a try?
Among Japanese people, approximately how many have hay fever (what is the ratio)?
- About one in two
- About one in three
- About 1 in 5 people
See the answer
About one in two
According to a recent survey by the Journal of the Oto-Rhino-Laryngological Society of Japan, 42.5% of Japanese people—roughly one in two—are said to have hay fever. Pollen from Japanese cedar and cypress is a major cause, and the number of patients has been increasing year by year.
During a typical day, at what time are pollen levels highest?
- Early morning (6:00–8:00)
- Around lunchtime (11:00–13:00)
- Evening (5:00–7:00 PM)
See the answer
Around lunchtime (11:00–13:00)
Pollen starts to disperse in the morning and reaches its peak as daytime temperatures rise. It is said to be most abundant around midday, especially between 11:00 and 13:00. After that, levels temporarily subside in the afternoon, but they can increase again around sunset in the early evening. This is because temperature changes in the evening cause pollen in the upper air to descend and pollen that has settled on the ground to become airborne again.
