In spring and fall, pollen from trees, grasses, and weeds induces an immune response in us, causing us to experience cold-like symptoms.

Scientists and physicians studied allergic diseases less during this time than later, and therefore these diseases were relatively less recognized in society. After the 1810s, however, increasing numbers of scientists and physicians published their research data and ideas about the cause of hay fever and treatment protocols. They advocated for therapies based on what they thought the cause of hay fever was; some therapies included medications (antispasmodics, narcotics, expectorants, emetics), rest and isolation, bloodletting, and irrigating nasal passages with caustic substances.<\/p>\n<figure id=\"attachment_28789\" aria-describedby=\"caption-attachment-28789\" style=\"width: 300px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"28789\" data-permalink=\"https:\/\/circulatingnow.nlm.nih.gov\/2024\/04\/05\/hay-fever-the-nuisance-of-a-new-season\/101603307-cover\/\" data-orig-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?fit=769%2C1200&amp;ssl=1\" data-orig-size=\"769,1200\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"101603307-cover\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Hay-fever and Its Successful Treatment, 1899&lt;br \/&gt;\nNational Library of Medicine #101603307&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?fit=192%2C300&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?fit=656%2C1024&amp;ssl=1\" class=\"wp-image-28789\" title=\"Cover of the Second Edition\" src=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?resize=300%2C468&#038;ssl=1\" alt=\"The cloth cover of a hardback book with the title and a botanical illustration of a flowering plant.\" width=\"300\" height=\"468\" srcset=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?resize=656%2C1024&amp;ssl=1 656w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?resize=192%2C300&amp;ssl=1 192w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?resize=768%2C1198&amp;ssl=1 768w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101603307-cover.jpg?w=769&amp;ssl=1 769w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-28789\" class=\"wp-caption-text\"><em>Hay-fever and Its Successful Treatment<\/em>, 1899<br \/><a href=\"http:\/\/resource.nlm.nih.gov\/101603303\">National Library of Medicine #101603307<\/a><\/figcaption><\/figure>\n<p>In the book <i><a href=\"http:\/\/resource.nlm.nih.gov\/64530770R\">Better than Gold; or Light Out of Darkness<\/a>,<\/i> Dr. E.

Many people\u2014even people of science\u2014believed that only the well off and educated suffered from seasonal allergies. Physicians observed that most of their allergy patients were wealthy and white. Without accounting for the lack of access to healthcare that the poor and people of color faced, they concluded that the moneyed were biologically more prone to hay fever.<\/p>\n<figure id=\"attachment_28797\" aria-describedby=\"caption-attachment-28797\" style=\"width: 236px\" class=\"wp-caption alignright\"><a href=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101224468-1.jpg?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"28797\" data-permalink=\"https:\/\/circulatingnow.nlm.nih.gov\/2024\/04\/05\/hay-fever-the-nuisance-of-a-new-season\/the-white-mountain-village-of-bethlehem-as-a-resort-for-health-a\/\" data-orig-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101224468-1.jpg?fit=707%2C1200&amp;ssl=1\" data-orig-size=\"707,1200\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;The White-Mountain village of Bethlehem as a resort for health a&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"The White-Mountain village of Bethlehem as a resort for health a\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;wffewfefwefw&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101224468-1.jpg?fit=177%2C300&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101224468-1.jpg?fit=603%2C1024&amp;ssl=1\" class=\"wp-image-28797\" src=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101224468-1.jpg?resize=236%2C400&#038;ssl=1\" alt=\"A book title page\" width=\"236\" height=\"400\" srcset=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101224468-1.jpg?resize=603%2C1024&amp;ssl=1 603w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101224468-1.jpg?resize=177%2C300&amp;ssl=1 177w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/101224468-1.jpg?w=707&amp;ssl=1 707w\" sizes=\"auto, (max-width: 236px) 100vw, 236px\" \/><\/a><figcaption id=\"caption-attachment-28797\" class=\"wp-caption-text\">A pamphlet about Bethlehem, a &#8220;health city&#8221; in White Mountain, NH, 1880 <br \/><a href=\"http:\/\/resource.nlm.nih.gov\/101224468\"><em>National Library of Medicine #101224468<\/em><\/a><\/figcaption><\/figure>\n<p>Every spring and fall, rich people with stuffy noses and watery eyes would seek refuge in the mountains or by the shore.\u00a0 A hay fever vacation industry developed for the leisure class, concentrated in areas far away from both the urban masses and the tuberculosis patients at the <a href=\"https:\/\/circulatingnow.nlm.nih.gov\/2022\/02\/24\/patient-pamphlet-for-piedmont-tb-sanatorium-va-1940\/\">sanitoriums<\/a> in the countryside.

People with seasonal allergies are encouraged to limit their exposure to pollen by remaining indoors when the pollen count is high, wearing a mask when doing yard work, keeping car windows closed, and more. Initially, the guidance only advised people to steer clear of outdoor dangers, but during the post-World War II housing boom, messaging expanded to promote creating an allergen-free home environment.<\/p>\n<p>La Comite\u0301 contre la tuberculose et les maladies respiratoires Martinique (The Committee Against Tuberculosis and Respiratory Maladies Martinique) published this pair of public health posters (below). One highlights activities that may improve asthma and allergies, including getting fresh air, breastfeeding newborns with asthma, playing sports, and getting sunlight on your bedding (presumably, to kill dust mites). The other poster points out common household respiratory irritants that one might remove to breathe easy at home, like cigarette smoke and down feathers.<\/p>\n<figure id=\"attachment_28786\" aria-describedby=\"caption-attachment-28786\" style=\"width: 840px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"28786\" data-permalink=\"https:\/\/circulatingnow.nlm.nih.gov\/2024\/04\/05\/hay-fever-the-nuisance-of-a-new-season\/martiniquais-hayfever\/\" data-orig-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?fit=1600%2C1074&amp;ssl=1\" data-orig-size=\"1600,1074\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"Martiniquais-hayfever\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?fit=300%2C201&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?fit=840%2C564&amp;ssl=1\" class=\"wp-image-28786 size-large\" src=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?resize=840%2C564&#038;ssl=1\" alt=\"Two public health posters side-by-side, pointing out common allergens and things that can improve allergies\" width=\"840\" height=\"564\" srcset=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?resize=1024%2C687&amp;ssl=1 1024w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?resize=300%2C201&amp;ssl=1 300w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?resize=768%2C516&amp;ssl=1 768w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?resize=1536%2C1031&amp;ssl=1 1536w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?resize=1200%2C806&amp;ssl=1 1200w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?resize=840%2C564&amp;ssl=1 840w, https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2024\/04\/Martiniquais-hayfever.jpg?w=1600&amp;ssl=1 1600w\" sizes=\"auto, (max-width: 840px) 100vw, 840px\" \/><\/a><figcaption id=\"caption-attachment-28786\" class=\"wp-caption-text\"><i>Pour lutter contre l&#8217;asthme et les allergies<\/i> poster and <i>Facteurs favorisant l&#8217;asthme et les allergies<\/i> poster, c. 1990<br \/><a href=\"http:\/\/resource.nlm.nih.gov\/101438553\"><em>National Library of Medicine #101438553<\/em><\/a> and <a href=\" http:\/\/resource.nlm.nih.gov\/101438548\"><em>National Library of Medicine #101438548<\/em><\/a><\/figcaption><\/figure>\n<p>The two posters below have slightly stronger messaging. <a href=\"http:\/\/resource.nlm.nih.gov\/101449650\">Allergies, the Facts<\/a>, sponsored jointly in 1991 by the Pharmacy Planning Service, the Allergy Council of America, and the American Academy of Allergy and Immunology, gave directives for avoiding allergens and provided a phone number for questions.
