<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
It's been a string of hot days, hasn't it?<\/p>\n
Are you wearing an air-conditioned suit?<\/p>\n
Shorts are all the rage these days!<\/p>\n
<\/p>\n
I've been seeing them quite often in private construction projects for the past few years.<\/p>\n
It seems to be gradually gaining traction, as even major companies are surprisingly granting permits for public works projects.<\/p>\n
I was wondering if our work uniforms might be used as shorts, so I did some research.<\/p>\n
That turned out to be an unexpected result, lol.<\/p>\n
<\/p>\n
One of our employees was doing it, so I asked them about it, and they said, \u201cIt\u2019s nice and cool.\u201d Haha.<\/p>\n
It seems that whether or not it\u2019s cool depends on the following factors.<\/p>\n
Breathability (Airflow)<\/span><\/strong><\/p>\n Heat Dissipation (Radiation, Convection, Evaporation)<\/span><\/strong><\/p>\n Evaporation Efficiency of Sweat<\/span><\/strong><\/p>\n Preventing an Increase in Skin Surface Temperature<\/span><\/strong><\/p>\n Shorts plus leggings have a structure with \u201clittle air space between the skin and the fabric,\u201d whereas regular pants (work pants) have a structure with \u201cloose-fitting fabric and air space.\u201d<\/p>\n <\/p>\n They look stylish and cool, but since a larger air pocket actually keeps you cooler, pants seem to be a good way to prevent heatstroke.<\/p>\n Short spandex shorts may look cool, but it turns out that while the person wearing them may feel cool, the data actually shows they aren't...<\/p>\n It's the placebo effect, isn't it?<\/p>\n <\/p>\n Even if it doesn't work scientifically, it all comes down to the person's motivation, huh? lol<\/p>\n I think it's also important to create a work environment where people feel comfortable.<\/p>\n <\/p>\n See you later.<\/p>","protected":false},"excerpt":{"rendered":" Hello, everyone.

Experimental Data and Research<\/h2>\n
\n
\nAccording to a comparative experiment on the WBGT (heat index) of work clothes, breathability and the presence or absence of airflow inside the garment strongly influence the perceived temperature; it appears that even with the same material, \u201ctight-fitting spats are more prone to trapping heat.\u201d<\/li>\n
\nCompression tights, which are used in activities such as marathon running and soccer, are designed to \u201csupport muscles and reduce fatigue,\u201d but are considered less breathable than regular lightweight shorts (according to a paper published by the Japanese Society of Physical Education in the field of exercise physiology).<\/li>\n
\nFor air-conditioned clothing that draws in airflow, \u201cair circulation inside the pants is considered important,\u201d and loose-fitting pants are said to enhance the cooling effect. It has been pointed out that leggings may hinder the effectiveness of air-conditioned clothing.<\/li>\n<\/ul>\nPractical Conclusions for the Field<\/h2>\n
\n
\n\u2192 Although sweat evaporates at the surface, the tight fit of the spats causes heat to build up easily. This tight fit hinders heat dissipation, which is a disadvantage during long work sessions.
\n\u2192 While effective for sports (short duration, high intensity), it tends to feel hot during long hours of work on construction sites.<\/li>\n<\/ul>\n\n
\n\u2192 An \u201cair layer\u201d forms between the fabric and the legs, allowing for heat exchange with the outside air. The combination of the air layer and airflow makes it easier to dissipate heat, which is an advantage. Works perfectly with climate-controlled clothing.
\n\u2192 Since long pants allow airflow from windbreakers and air-conditioned clothing to circulate, they keep you cooler.<\/li>\n<\/ul>\n![\"Work](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2025\/08\/w_nok_ga3916_main-1.jpg\")
