“…Some have considered subjects to investigate the body heat balance ( Büttner, 1934 ; Winslow et al., 1936 , 1939 ; Hardy and DuBois, 1938 ; Nelson et al., 1947 ; Nielsen and Pedersen, 1952 ; Colin and Houdas, 1967 ; Woodcock and Breckenridge, 1965 ; Mitchell et al., 1969 ; Clark et al., 1974 ; Clark and Toy, 1975 ; Galimide et al., 1979 ; Ishigaki et al., 1993 ; Ishii et al., 2000 ). Some have considered a thermal manikin ( Nielsen and Pedersen, 1952 ; Lee et al., 1991 ; Tanabe et al., 1994 ; deDear et al., 1997 ; Ichihara et al., 1997 ; Mochida et al., 1999 ; Kuwabara et al., 2001 ; Ozeki et al., 2002 ; Oguro et al., 2002a , 2002b ; Kurazumi et al., 2006 , 2008a , 2008b , 2013 , 2014 ; Watanabe et al., 2008 ; Luo et al., 2014 , 2015 ; Li and Ito, 2014 ; Yang et al., 2018 ; Yu et al., 2020 ).

“…Some research has involved the use of simple heat-emitting devices or assemblies to model the convective heat transfer coefficient of the human body (Stolwijk 1970;Rapp 1973;Mochida 1977aMochida , 1977bHorikoshi et al 1990aHorikoshi et al , 1990bLee et al 1990), while other researchers have used real subjects to investigate the heat balance of the human body (Bu¨ttner 1934;Winslow et al 1936Winslow et al , 1939Hardy and DuBois 1937;Nelson et al 1947;Nielsen and Pedersen 1952;Colin and Houdas 1967;Woodcock and Breckenridge 1965;Mitchell et al 1969;Clark et al 1974;Clark and Toy 1975;Galimide et al 1979;Ishigaki et al 1993;Choi et al 1996;Ishii et al 1998Ishii et al , 2000. Others have used thermal mannequins (Nielsen and Pedersen 1952;Lee et al 1991;Tanabe and Hasegawa 1993;Tanabe et al 1994;de Dear et al 1997;Ichihara et al 1997;Zeng et al 1998;Murakami et al 1999;Mochida et al 1999;Kuwabara et al 2001;Ozeki et al 2002;Oguro et al 2002aOguro et al , 2002b, and some have used to the mass and heat transport theories of naphthalene (Nishi and Gagge 1970;Neal 1975;Chan...…”

In order to clarify the heat transfer area involved in convective heat exchange for the human body, the total body surface area of six healthy subjects was measured, and the non-convective heat transfer area and floor and chair contact areas for the following nine common body positions were measured: standing, sitting on a chair, sitting in the seiza position, sitting cross-legged, sitting sideways, sitting with both knees erect, sitting with a leg out, and the lateral and supine positions. The main non-convective heat transfer areas were: the armpits (contact between the upper arm and trunk regions), contact between the two legs, contacts between the fingers and toes, and contact between the hands and the body surface. Also, when sitting on the floor with some degree of leg contact (sitting in the seiza position, cross-legged, or sideways), there was a large non-convective heat transfer area on the thighs and legs. Even when standing or sitting in a chair, about 6-8% of the body surface did not transfer heat by convection. The results showed that the effective thermal convective area factor for the naked whole body in the standing position was 0.942. While sitting in a chair this factor was 0.860, while sitting in a chair but excluding the chair contact area it was 0.918, when sitting in the seiza position 0.818, when sitting cross-legged 0.843, in the sideways sitting position 0.855, when sitting with both knees erect 0.887, in the leg-out sitting position 0.906, while in the lateral position it was 0.877 and the supine position 0.844. For all body positions, the effective thermal convective area factor was greater than the effective thermal radiation area factor, but smaller than the total body surface area.
