夏季生活常识中的五个误区
夏季生活常识中的五个误区
1.天越热,衣服穿的越少
研究表明,赤膊只能在皮肤温度高于环境温度时,增加皮肤的辐射、传导散热,而盛夏酷暑之日,气温一般都接近或超过37℃,皮肤不但不能散热,反而会从外界环境中吸收热量,因而打赤膊会感觉更热。另外,夏天喝啤酒能解暑是不可否认的,但是,多喝照样能使人感觉口干咽燥、全身发热。因为啤酒含有酒精,喝得过多,不仅达不到解暑的目的,反而会降低人的思维能力和工作效率,甚至会造成工作中的差错事故。
2.夏季晨练越早越好
研究表明,夏季空气污染物在早晨6点前最不易扩散,此时常是污染的高峰期。人们普遍喜欢在草坪、树林、花丛等有绿色植物生长的地方进行晨练,而日出之前,因为没有光合作用,绿色植物附近非但没有多少新鲜的氧气,相反倒积存了大量的二氧化碳,这对人体健康显然是不利的。所以夏季晨练的时间不宜早于6点。
3.空调应保持恒温或准恒温状态
医疗气象学家通过试验发现,不断调节居室温度,可以使人的生理体温调节机制不断地处于“紧张状态”,从而逐渐适应温度的急剧变化,提高人的自我保护能力,不至于经常感冒或患其他居室病症。因此,刚开始利用空调进行这种调节时,整个居室的温度变化幅度应控制在3℃至5℃;半个月后,幅度可逐渐提高到6℃至10℃。温度变化也不要太突然,而是要平稳地提高或降低(每次调节以1℃至2℃为宜)。
4.太阳镜颜色越深越能保护眼睛
如果镜片颜色过深,会严重影响能见度,眼睛因看东西吃力而容易受到损伤,不能起到保护眼睛的作用。专家建议,夏季选择太阳镜的标准是:镜片应能穿过15%~30%的可见光线,以灰色和绿色为最佳,这样,不但可抵御紫外线,而且视物清晰度最佳,外界物体颜色变化也最小。
5.夏季“冲凉”最舒服
炎炎夏日,人们外出活动时会吸收大量的热量,人体肌肤的毛孔都处于“张开”的状态,而立即“冲凉”会使全身毛孔迅速闭合,使得热量不能散发而滞留体内,从而易引起高热症;同时,“冲凉”之时,因脑部毛细血管迅速收缩,也容易引起供血不足,使人头晕目眩,重者还可能引起休克。因此,夏季外出回家,应先让自己出出汗,待身上的热散发过后,再采取一些清凉措施。

No young man believes he shall ever die. It was a saying of my brother’s, and a fine one. There is a feeling of Eternity in youth, cat supplies which makes us amend for everything. To be young is to be as one of the Immortal Gods. One half of time indeed is flown-the other half remains in store for us with all its countless treasures; for there is no line drawn, and we see no limit to our hopes and wishes. dog apparel We make the coming age our own -- The vast, the unbounded prospect lies before us
Death. old age. are words without a meaning. dog bags that pass by us like the idea air which we regard not. Others may have undergone, or may still be liable to them-we "bear a charmed life”, which laughs to scorn all such sickly fancies. As in setting out on delightful journey, dog beds we strain our eager gaze forward- Bidding the lovely scenes at distance hail!-and see no end to the landscape, new objects presenting themselves as we advance; so, in the commencement of life, we set no bounds to our inclinations. nor to the unrestricted opportunities of gratifying them. we have as yet found no obstacle, no disposition to flag; dog bowls and it seems that we can go on so forever.
We look round in a new world, full of life, and motion, and ceaseless progress; and feel in ourselves all the vigor and spirit to keep pace with it, and do not foresee from any present symptoms how we shall be left behind in the natural course of things, decline into old age, and drop into the grave. It is the simplicity, and as it were abstractedness of our feelings in youth, that (so to speak) identifies us with nature, and (our experience being slight and our passions strong) deludes us into a belief of being immortal like it. Our short-lives connection with existence we fondly flatter ourselves, dog carriers is an indissoluble and lasting union-a honeymoon that knows neither coldness, jar, nor separation. As infants smile and sleep, we are rocked in the cradle of our wayward fancies, and lulled into security by the roar of the universe around us.
we quaff the cup of life with eager haste without draining it, dog clothes instead of which it only overflows the more objects press around us, filling the mind with their magnitude and with the strong of desires that wait upon them, dog clothing so that we have no room for the thoughts of death.
