冬季生活小常识
1、门窗紧闭
冬季门窗紧闭，减少了空气对流，使室内温度上升；但也导致不洁的空气增多，空气中细菌、病毒、二氧化碳和尘粒大量增加，对呼吸道有不良影响，使人易患感冒、咳嗽、咽炎等疾病。
2、皮肤发痒用手抓
冬天因干燥感到皮肤发痒时，切不可用手抓搔，否则易抓破皮肤引起继发性感染。防治方法是多饮水，多吃新鲜蔬菜、水果，少吃酸辣等刺激性食物，少饮烈性酒。勤洗澡，勤换内衣。瘙痒严重者，可服用扑尔敏、非那根等药物，也可涂些炉甘石剂或肤轻松软膏。
3、蒙头睡觉
蒙头睡觉会使被子里的氧气越来越少，二氧化碳与不洁气体越来越多，醒后会感到昏昏沉沉，疲乏无力。
4、热水洗脸
在冬季冷空气的刺激下，面部汗腺、毛细血管呈收缩状态。而遇热水时会迅速扩张，待热量散发后，又恢复低温时的状态。毛细血管如此一张一缩，易使面部产生皱纹。
5、手脚冷冻用火烤
冬季手脚长期暴露在外，血管收缩、血流量减少。此时，若立即用火烘烤会使血管麻痹、失去收缩力，出现动脉淤血、毛细血管扩张、渗透性增强，局部性淤血。轻则形成冻疮，重则造成组织坏死。
6、舔嘴唇防干燥：
嘴唇干燥不舒服时，用舌头去舔，结果越舔越干，导致口唇皮肤粗糙变厚，嘴唇肿胀，形成“舌舔皮炎”。这是因为唾液中含有黏液蛋白、唾液淀粉酶和无机盐类物质，舔嘴唇时，犹如在嘴唇上抹了一层糨糊，水分蒸发后，这层糨糊发生干缩，感觉更干燥，直至造成嘴唇肿胀、破裂流血。
7、“全副武装”防冻疮：
入冬，穿得太厚以御寒，会削弱机体对寒冷的适应力，而且因限制了运动，末梢血液循环不够，反倒更容易长冻疮。正确的作法是，衣物适当，多进行运动，经常搓手、跺脚，用热水泡浴等。
An earthquake is a shaking of the ground caused by the sudden breaking and shifting of
large sections of Earth''s rocky outer shell.
rs2 powerleveling Earthquakes are
among the most powerful events on earth, and their results can be terrifying. A severe
earthquake may release energy 10,000 times as great as that of the first atomic bomb. Rock
movements during an earthquake can make rivers change their course.
yantai Earthquakes can trigger landslides that
cause great damage and loss of life. Large earthquakes beneath the ocean can create a
series of huge,

destructive waves called tsunamis (pronounced tsoo NAH meez) that flood coasts for many
miles.
Earthquakes almost never kill people directly. Instead, many deaths and injuries in
earthquakes result from falling objects and the collapse of buildings,
lineage2 adena bridges, and other
structures. Fire resulting from broken gas or power lines is another major danger during a
quake. Spills of hazardous chemicals are also a concern during an earthquake.
The force of an earthquake depends on how much rock breaks and how far it shifts.
Lineage2 powerleveling Powerful
earthquakes can shake firm ground violently for great distances. During minor earthquakes,
the vibration may be no greater than the vibration caused by a passing truck.
On average, a powerful earthquake occurs less than once every two years.

moderate earthquakes cause damage somewhere in the world each year.
yantai About 40,000 to 50,000 small earthquakes--
large enough to be felt but not damaging--occur annually.

8、戴口罩保护呼吸道：
鼻粘膜里有丰富的血管和海绵状血管网，血液循环旺盛，当冷空气经鼻腔吸入肺部时，一般已接近体温。若依赖戴口罩防寒，会使人体变得娇气，反而更易感冒。
9、喝烈性酒防寒：
酒精并不产生热量。饮酒后，由于外周血管广泛扩张，热量通过皮肤向外散发，会使人觉得很温暖。但机体不正常的散热会使热量大量丧失，暖和的感觉最终会被寒冷所代替。
