Hay fever is not a true fever, meaning it does not cause a core body temperature in the fever over 37.5–38.3 °C (99.5–100.9 °F). Cause [ edit ] Allergic rhinitis triggered by the pollens of specific seasonal plants is commonly known as "hay fever", because it is most prevalent during haying season.
Hay Fever is a comic play written by Noël Coward in 1924 and first produced in 1925 with Marie Tempest as the first Judith Bliss. A cross between high farce and a comedy of manners, the play is set in an English country house in the 1920s, and deals with the four eccentric members of the Bliss family and their outlandish behaviour when they each invite a guest to spend the weekend.

Hay fever, also called allergic rhinitis, causes cold-like signs and symptoms, such as a runny nose, itchy eyes, congestion, sneezing and sinus pressure. But unlike a cold, hay fever isn't caused by a virus. Hay fever is caused by an allergic response to outdoor or indoor allergens, such as pollen, dust mites, or tiny flecks of skin and saliva shed by cats, dogs, and other animals with fur or feathers (pet dander).Besides making you miserable, hay fever can affect your performance at work or...
Hay fever signs and symptoms can include: 1. Runny nose and nasal congestion 2. Watery, itchy, red eyes (allergic conjunctivitis) 3. Sneezing 4. Cough 5. Itchy nose, roof of mouth or throat 6. Swollen, blue-colored skin under the eyes (allergic shiners) 7. Postnasal drip 8. Fatigue
When you have hay fever, your immune system identifies a harmless airborne substance as harmful. Your immune system then produces antibodies to this harmless substance. The next time you come in contact with the substance, these antibodies signal your immune system to release chemicals such as histamine into your bloodstream, which cause a reaction that leads to the signs and symptoms of hay fever.
The following can increase your risk of developing hay fever: 1. Having other allergies or asthma 2. Having atopic dermatitis (eczema) 3. Having a blood relative (such as a parent or sibling) with allergies or asthma 4. Living or working in an environment that constantly exposes you to allergens — such as animal dander or dust mites 5. Having a mother who smoked during your first year of life
Problems that may be associated with hay fever include: 1. Reduced quality of life. Hay fever can interfere with your enjoyment of activities and cause you to be less productive. For many people, hay fever symptoms lead to absences from work or school. 2. Poor sleep. Hay fever symptoms can keep you awake or make it hard to stay asleep, which can lead to fatigue and a general feeling of being unwell (malaise). 3. Worsening asthma. Hay fever can worsen signs and symptoms of asthma, such as coug...
There's no way to avoid getting hay fever. If you have hay fever, the best thing to do is to lessen your exposure to the allergens that cause your symptoms. Take allergy medications before you're exposed to allergens, as directed by your doctor.

Hay fever in Japan is most commonly caused by pollen from Cryptomeria japonica and Japanese cypress, two native Japanese tree species.
Hay fever was relatively uncommon in Japan until the early 1960s. Shortly after World War II, reforestation policies resulted in large forests of cryptomeria and Japanese cypress trees, which were an important resource for the construction industry. As these trees matured, they started to produce large amounts of pollen. Peak production of pollen occurs in trees of 30 years and older. As the Japanese economy developed in the 1970s and 1980s, cheaper imported building materials decreased the dema
Cryptomeria pollen dispersal starts when average daily temperatures reach 10 degrees Celsius, partly depending on wind and terrain. Like the cherry blossom season, the pollen season moves from south to north across Japan, and from lower to higher elevations as spring progresses. For western and eastern Japan this means the hay fever season starts between end of January and mid-February. The cryptomeria pollen season peaks in the second half of March - first half of April in these areas, then dec
Japanese media track and report on the developing pollen season in ways similar to the prediction and tracking of the cherry blossom season. The Japan Weather Association and Weathernews Japan particularly collect and provide detailed information on pollen counts in locations across Japan. Besides daily or even hourly information during the pollen season, JWA provides a long term forecast in the fall of the expected severity of the coming season. The amount of flowering and pollen production dep
A sizable industry has developed in Japan around services and products that help people deal with hay fever, including protective wear such as coats with smooth surfaces, masks, and glasses; medication and remedies; household goods such as air-conditioner filters and fine window screens; and even "hay fever relief vacations" to low-pollen areas such as Okinawa and Hokkaido. Some people in Japan use medical laser therapy to desensitize the parts of their nose that are sensitive to pollen.
As the impact of the allergy season on the population has mounted, the Japanese government has increasingly focused attention on the issue. In 1990, the Ministry of Agriculture started a series of annual Hay Fever Conferences to coordinate among government institutions involved. The Liberal Democratic Party submitted a motion on Anti Allergy and Hay Fever Measures in 1995, greatly influenced by increasing lobbying. The government budget for addressing pollen allergies has greatly increased since
