[For General Readers] Little-Known Trivia and Fun Facts about Hay Fever (11–20)
Hay fever symptoms can sometimes improve with sunbathing.
Sunbathing, which is strongly associated with refreshing your mood, is said to help suppress hay fever symptoms.
Sun exposure generates vitamin D, which acts on the immune system to reduce symptoms.
Since maintaining a balanced immune system is considered essential for managing allergies, make sure to get some sunlight to help keep your immunity in good shape.
Sunlight alone won’t fully control symptoms, so it’s also recommended to maintain a regular, healthy lifestyle.
The pollen that causes hay fever is in the air all year round.
When it comes to hay fever, many people strongly associate it with spring and the pollen from Japanese cedar and cypress.
However, pollen that causes hay fever is in the air year-round, and depending on your allergic reactions, you might suffer throughout the entire year.
Cedar and cypress peak from February to April; in early summer, grasses release pollen, and in autumn, ragweed does—on top of that, alder, mugwort, and others fill in the gaps, making for a dismal situation.
It may be important to get tested to find out which pollens you react to and to know which seasons you should pay particular attention to.
Eating too much meat can make allergy symptoms more likely.
Many people like beef and pork.
However, it’s said that they may actually worsen hay fever.
Let me explain the mechanism step by step.
First, when you eat foods that are high in protein, your digestive enzyme secretion can struggle to keep up.
As a result, your body treats the undigested components as foreign substances and activates the immune system to deal with them.
This makes you more prone to allergic reactions to things like pollen.
By the way, dairy products, which are also high in protein, may likewise worsen hay fever.
In buildings like offices and apartment complexes, the middle floors tend to have more pollen.
Because pollen floating in the air is invisible, understanding how it becomes airborne can help you take preventive measures.
It’s said that in high-rise buildings and tower apartments, pollen tends to concentrate on the middle floors.
In addition to pollen falling from the sky, pollen that has settled on the ground can be stirred up again, and these two streams collide and linger around the mid-levels.
Let’s make solid predictions about pollen movement based on the day’s conditions and stay mindful of measures that vary by location.
There is little cedar pollen in Okinawa and Hokkaido.
People across a wide range of regions and age groups suffer from hay fever, and those who struggle with it often dream of ways to escape.
One option for escaping hay fever within Japan is to head to Okinawa or Hokkaido.
This isn’t just a rumor—there’s a clear reason: cedar and cypress trees are extremely scarce in Hokkaido and Okinawa, which means there’s far less pollen in the air.
During the season when hay fever gets severe, why not consider traveling to areas with fewer cedar and cypress trees and make a trip of it? However, be aware that Hokkaido does have other pollen sources, such as birch and alder, which can also cause allergic reactions.
