Inducing urticarial wheals using light sources of pertinent wavelengths can help make the definitive diagnosis of PU. The action spectra (AS) in Japanese patients with PU commonly fall within the ultraviolet radiation A and visible light range. Herein, to the best of our knowledge, we present the first case of PU caused by 633\u2010nm wavelength within the visible light spectrum. Our patient worked as a \u201chot yoga\u201d instructor, where light\u2010emitting diodes (LEDs) on the ceiling were used to irradiate the entire room with 633\u2010nm wavelength of light for \u201clight treatment.\u201d She reported itching and wheals on the face and neck during her \u201chot yoga\u201d sessions. \u201cHot yoga\u201d has recently gained popularity globally. The \u201clight treatment\u201d is based on the theory that 633\u2010nm wavelength light within the visible light spectrum reportedly prevents the skin from aging. We induced wheals with erythema by irradiating her skin using a 633\u2010nm LED at a dose of 0.008\u00a0J\/cm<jats:sup>2<\/jats:sup>\/s for 1\u00a0h. Her condition was diagnosed as PU caused by exposure to 633\u00a0nm. Light. Her symptoms have not recurred since she has avoided being exposed to the 633\u2010nm wavelength of LED light.<\/jats:p>","DOI":"10.1111\/phpp.12757","type":"journal-article","created":{"date-parts":[[2021,12,9]],"date-time":"2021-12-09T15:59:39Z","timestamp":1639065579000},"page":"395-396","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Photo urticaria caused by exposure to LED emitting 633\u2010nm wavelength during hot yoga exercise"],"prefix":"10.1111","volume":"38","author":[{"given":"Anna","family":"Takeuchi","sequence":"first","affiliation":[{"name":"Division of Dermatology Department of Internal Related Kobe University Graduate School of Medicine  Kobe Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Fukumoto","sequence":"additional","affiliation":[{"name":"Division of Dermatology Department of Internal Related Kobe University Graduate School of Medicine  Kobe Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chikako","family":"Nishigori","sequence":"additional","affiliation":[{"name":"Division of Dermatology Department of Internal Related Kobe University Graduate School of Medicine  Kobe Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"key":"e_1_2_3_2_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2133.2000.03238.x"},{"key":"e_1_2_3_3_1","first-page":"1250","article-title":"Solar urticaria","volume":"13","author":"Goetze S","year":"2015","journal-title":"J Dtsch Dermatol Ges"},{"key":"e_1_2_3_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/ajd.12975"},{"key":"e_1_2_3_5_1","doi-asserted-by":"publisher","DOI":"10.3892\/ijmm.2014.2030"},{"key":"e_1_2_3_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/14764170500370059"}],"container-title":["Photodermatology, Photoimmunology &amp; Photomedicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/phpp.12757","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/phpp.12757","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/phpp.12757","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,23]],"date-time":"2023-08-23T18:39:45Z","timestamp":1692815985000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/phpp.12757"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,12,15]]},"references-count":5,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2022,7]]}},"alternative-id":["10.1111\/phpp.12757"],"URL":"https:\/\/doi.org\/10.1111\/phpp.12757","archive":["Portico"],"relation":{},"ISSN":["0905-4383","1600-0781"],"issn-type":[{"value":"0905-4383","type":"print"},{"value":"1600-0781","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,12,15]]},"assertion":[{"value":"2021-08-30","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-12-07","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-12-15","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
