【TIME】What to Wear When It’s Really Hot Outside

dissipate

意味　〈熱など〉を逃がす .

“We human beings really need to balance heat and moisture to feel good,” Song says. “That’s why in different seasons we wear different things. The clothing mediates how much heat dissipates into the environment.”

年中汗っかきで衣替えしない（冬コートの有無くらい）んだけどだめかしら。

assume

意味　〈人が〉（証拠はないが）〈事〉を本当だと思う

And, contrary to what you might assume, wearing as little clothing as possible isn’t always the best strategy. Garments that provide some coverage prevent the sun from beating down directly on your bare skin, says Margaret Frey, a professor of fiber science and apparel design at Cornell University. “We can look for inspiration from traditional dress from very warm climates,” Frey says. “In a lot of them, they are wearing things that actually cover most of the body but are not tight-fitting.” People from desert climates, for example, often wear full-body robes.

長袖の方が陽射しの暑さは防げるね。だから半袖服持ってない、一年中長袖。

synthetic

意味　[化] 合成の.

If you’re going to be exercising or sweating heavily, however, Song says you may want to go for a synthetic, moisture-wicking fabric. Natural fibers like cotton and linen absorb sweat, whereas engineered textiles “dry fast and transport your moisture to the outside,” he says.

綿や麻の方がポリエステルより着心地いいけど、汗じみが目立つのよね。

identical

意味　〈別の物· 事· 人が〉 まったく同じの, そっくりそのままの, あらゆる点で一致する ; 一致している, 同じである

There’s a reason white clothing is popular in the summer. Garments in dark colors like black, navy, and forest green absorb more of the sun’s UV radiation than light-colored clothes. Researchers in Japan have run experiments in which multiple polo shirts—identical except for their colors—are left outside on sunny days. The dark shirts get significantly hotter than the light shirts even after a relatively short time outside, they report. For that reason, Song, McMahon, and Frey all recommend light-colored clothing during the summer.

susceptible

意味　＜…の＞ 影響を受けやすい＜to＞

And there is a tradeoff to wearing light clothing, Frey adds. Light-colored clothes aren’t as effective at protecting your skin from the sun as dark clothes are, meaning you may be more susceptible to sunburns and skin damage if you’re decked out in gauzy white cotton. Compensate by wearing plenty of sunscreen—and by washing your clothes regularly, since many commercial detergents include brightening agents that may also boost UV protection, Frey says.
