Tips and tricks that help you keep your cool
    2017-June-27  08:53    Shenzhen Daily

A white cotton top and shorts is obviously the best thing to wear, right? Sort of.

Natural fabrics like linen and cotton absorb sweat and allow it to breathe. They’re much better than man-made fibers like polyester, which can trap the moisture against your skin, leaving you hot and uncomfortable.

But when it comes to color, things get a little more complicated.

White is good if you’re out in direct sunlight a lot — it will reflect the heat better than any other color. But if you’re spending time in the shade, black is a more effective color to wear as it radiates out heat into your environment, cooling you down.

Staying hydrated is key. According to the NHS, if you don’t drink lots of water and beverages like fruit juice, you can start to become unwell, with symptoms of headache and tiredness. It can lead to heat exhaustion and heatstroke, which in the worst cases can be fatal.

But what about hot drinks? Can they help cool you down?

Drinking hot drinks actually lowers your body temperature.

The thinking is, drinking a hot drink raises your body temperature, causing you to sweat. Sweating cools you down because as the moisture evaporates it takes away some of the heat of your body.

But sweating also means that you are losing liquid from your body, meaning you need to take on more to stay hydrated.

Do you keep the curtains closed to block out the sun? There is no precise answer.

If you have thick dark curtains, then keep them open, otherwise the fabric can keep the heat trapped in the room.

Lighter curtains can help reflect the sun’s rays back out of the room, so keep them closed.

Putting something reflective on the outside of the glass can bounce the heat away, keeping the room cool.

Do you leave the windows open to circulate the air?

You should always consider home security when it comes to leaving windows and doors open.

If the room you are in is actually cooler than the temperature outside then keep the windows closed, otherwise all you are doing is letting hot air in.

But if the room is warmer, then opening the windows will help cool your home down.

Words to Learn 相关词汇

【中暑】zhòngshǔ heatstroke a dangerous condition caused by the body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures

【流通】líutōng circulate cause to pass from place to place

白色棉质上衣搭配短裤显然是最佳着装,对吗?某种程度上是的。

亚麻、棉布等天然布料吸汗透气,比聚酯纤维等人造纤维要好得多,聚酯纤维会困住皮肤上的水分,让你感到闷热不适。

但说到颜色,情况更复杂一些。

如果直接在太阳下暴晒,那么白色是没错的。相比其他颜色,白色能更好反射热光。但是如果你身处阴凉处,那么黑色的效果会更好,因为它能把热量释放到环境中,为你降温。

保持水分非常关键。据英国国家医疗服务体系称,如果不摄入大量的水分或果汁等饮品,人们就会出现头痛、疲劳等不适症状。这可能导致热衰竭和中暑,最严重时可能危及生命。

那么热饮怎么样呢?它能让你凉快起来吗?喝热饮实际上会降低体温。

原理是:喝热饮让人体温升高,开始流汗。出汗能让你凉快,因为汗水蒸发会带走身体的部分热量。

但出汗也意味着体内水分流失,所以你需要喝更多来补充水分。

应该拉上窗帘,遮挡太阳吗?没有标准答案。

如果你家窗帘是深黑色的,那就把它拉开,否则窗帘会将热量关在房间里。

颜色较浅的窗帘有助于将太阳光反射出房间,所以请把它拉上。

在窗玻璃外面放一些反光的东西可以反射热量,让房间保持凉爽。

你开着窗让空气流通吗?

开窗或开门时,要时刻考虑家里的安全。

如果房间的温度比外面的温度低,那么就关上窗户,否则你只会把热空气放进来。

如果房间里更热,打开窗会让家更凉快些。(Chinadaily.com.cn)
