Hey Fever
Precautions when going out when pollen is scattered
(1) Pollen information
Pollen will fall to the ground when it rains, so the amount of scattering will be less on rainy days, but pollen will be scattered from afar when it stops raining. The pollen on the ground is also rolled up, so please consider that the scattered pollen will double.
・Morning and evening
In general, pollen tends to be dispersed more in the morning and evening, which is the time when commuting to work or school. It is thought that as the temperature rises with time from sunrise, the pollen tends to float to the level of the eyes and nose, and as the temperature drops towards the evening, the pollen that was in the sky descends (topography and buildings). , There are differences depending on the region, and the amount of scattering may increase around 13:00 to 15:00 when the temperature rises the most in a day).
(3) Clothes that prevent pollen from
sticking to your body Pollen tends to stick to your whole body, so wear a hat on your hair, wear glasses or a mask on your eyes and nose, and wear a muffler or scarf on your neck to prevent pollen from sticking to your body. Choose well-fitting outerwear.
(4) When returning home,
brush pollen in front of the entrance so as not to bring pollen into the house, change clothes immediately, and wash off the exposed face.
Nose and eye care for hay fever
(1) Nose care
It effectively removes pollen and dust that has entered the nose. However, since tap water contains chlorine and other substances, it can damage the mucous membrane of the nose, so please use a commercially available physiological saline solution with a composition similar to that of body fluids.
・Protection of the nasal mucous membrane
Repeatedly blowing your nose will cause your nose to become rough, so if it gets rough, apply white petrolatum, etc. Blowing your nose with moisturizing tissue is also helpful.
・Indoor humidification
If there is inflammation in the nasal cavity, the function of the mucous membranes will decrease, so please humidify the room and supplement the moisture. Masks are useful when the air is dry.
・Mask
Masks are expected to reduce nasal symptoms by reducing the amount of pollen inhaled to about one-third to one-sixth when there is a lot of pollen scattering. It is also expected that people who do not have hay fever will be less likely to develop hay fever again by reducing the amount of pollen they inhale. However, if the wind is strong, even if you are wearing a mask, more pollen will enter your nose. Even if you wear a mask, you will not be completely protected, so overconfidence is prohibited.

It is effective to wash away foreign substances such as pollen and dust. However, the surface of the eyes is protected by tears, and washing the eyes with tap water may damage the cells and wash away the tears, so please use commercially available artificial tears.
Avoiding Eye Fatigue
Watching TV or working on a computer for a long time puts a strain on your eyes and causes dry eyes and physical and mental health problems such as dizziness, headaches, and sleep disorders. It invites VDT syndrome (visual display terminal syndrome) that appears. Keep the distance from your eyes to the screen (monitor) about 50 cm, and after 1 hour of continuous viewing, take a break of about 15 minutes and stretch your body. Also, if your eyes are inflamed, that alone puts a strain on your eyes, so refrain from wearing contact lenses and wear glasses to consciously rest your eyes. It's not limited to the eyes, but please try to live a regular life and have enough sleep and a well-balanced diet.
About initial treatment
Hay fever generally becomes less effective as symptoms worsen, so it is recommended to start using drugs to suppress symptoms while the symptoms are mild. Initial therapy is started about two weeks before the predicted date of pollen dispersal, or when symptoms of hay fever appear even a little. By using the medicine early, it becomes easier to control the symptoms even when the amount of pollen dispersal increases, and you can spend the season with the symptoms suppressed.
About treatment
Treatment for hay fever is the same as treatment for allergic rhinitis, and there are three types of treatment: drug therapy, allergen immunotherapy, and surgical therapy. It is also important to create an environment that avoids pollen allergens that cause symptoms. Neurotransmitter dopamine gaba. Neurotransmitter glutamate. Neurotransmitters
Drug therapy includes oral antihistamines that suppress runny noses, nasal steroids that suppress nasal inflammation, and leukotriene receptor antagonists that improve nasal congestion. Antihistamines have side effects such as drowsiness, but in recent years there are some drugs that do not cause drowsiness.
For eye symptoms, mediator release inhibitors for various chemical mediators produced by exposure to pollen and antihistamine eye drops are used. If the pollen count increases and the symptoms worsen, steroid eye drops may be used for allergic eye inflammation. When using steroid eye drops, regular examinations by an ophthalmologist are necessary to check for side effects such as increased intraocular pressure.
Allergen immunotherapy, also called desensitization therapy, is a treatment that weakens the body's allergic response by administering the causative allergen. There are injection formulations and sublingual formulations (sublingual tablets). In Japan, cedar pollen and mites are covered by insurance for sublingual tablets. Treatment is necessary for several years and requires patience, but immunotherapy is recommended for patients who cannot continue treatment due to side effects of drug therapy, or for patients whose symptoms cannot be controlled with drug therapy alone. is taken into account.
Surgical therapy includes lower turbinate mucosa ablation, in which the nasal mucosa is coagulated with a laser. This treatment is considered when symptoms cannot be controlled with drug therapy.
About severity
The severity of hay fever is diagnosed by the number of times you blow your nose, the number of times you sneeze, and the number of times you breathe through your mouth for stuffy nose. Since a runny nose and sneezing are closely related, they are classified as "runny nose/sneezing type", "nasal congestion type" when nasal congestion is stronger than other symptoms, and "full type" when all three symptoms are equally strong.
Hay fever is not life-threatening even if it is severe, but oral allergy syndrome, which is a combination of hay fever and food allergy, is rare, but an anaphylactic reaction, which causes symptoms to appear throughout the body, may occur. is required.
About symptoms
The symptoms of hay fever are three main symptoms: runny nose, repeated sneezing, and stuffy nose. Itching and foreign body sensations also occur in the eyes, and symptoms tend to worsen in proportion to the amount of pollen scattered. Nasal symptoms make it difficult to breathe, which can have a major impact on your studies, work, and housework, such as decreased concentration and difficulty sleeping. In addition, some people with hay fever may experience itching, numbness, swelling, etc. on their lips, tongue, mouth, and throat within a few minutes after eating fruits and raw vegetables. This is called oral allergy syndrome and occurs because the allergens in pollen are similar to the allergens in fruits and vegetables.
