This　paper　attempts　to　answer　the　question　whether　there　is　any　difference　in　indoor　environmental　perceptions　between　people　with　and　without　respiratory　allergy.　First,　an　online　survey　was　conducted　in　China　inquiring　respondents’　sensitivity　to　changes　in　environmental　factors　including　indoor　air　temperature,　indoor　relative　humidity,　indoor　air　freshness,　and　outdoor　air　pollution.　Totally,　1293　persons　from　30　provinces　of　China　participated　in　the　survey,　including　478　allergics　and　815　non-allergics.　From　this　investigation　over　70%　of　allergics　reported　themselves　to　be　more　sensitive　to　four　respective　environmental　factors　than　others,　which　was　statistically　higher　than　the　ratio　of　non-allergics.　Secondly,　published　studies　on　environmental　perceptions　of　allergics　were　reviewed.　Ten　studies　were　identified　and　their　findings　suggest　that　perception　difference　of　thermal　environment　between　allergics　and　non-allergics　may　occur　when　subjects　are　not　thermally　neutral　while　perception　difference　of　air　quality　remains　unclear.　Therefore　further　research　on　this　question　is　needed.　©　2020,　Springer　Nature　Singapore　Pte　Ltd.
