简述心理应激引起的机体的变化。

答案

参考答案:

①当机体处于强烈的应激状态时,交感、肾上腺髓质系统的活动常有明显增强。在某些情况下,某些个体可出现副交感神经活动相对增强的情况,如心率减慢、心输出量和血压下降、血糖降低等,甚至导致休克等。②在心理应激状态下,下丘脑、腺垂体、肾上腺皮质轴活动增强,同时抑制葡萄糖的消耗,从而使血糖水平升高。有时盐皮质激素也增加,引起血容量增加。③心理神经免疫学的研究表明:大脑作为环境与免疫系统间的协调者,在调节机体对各种应激源的免疫防御中起重要作用。应激引起的交感、肾上腺系统兴奋可以伴有儿茶酚胺及阿片样物质的释放,作用于淋巴细胞受体。

Chinese New Year Celebration is the most important celebration of the year. Chinese people may celebrate the Chinese New Year in slightly different ways but their wishes are almost the same; they want their family members and friends to be healthy and lucky during next year.    

Chinese New Year Celebration usually lasts for 15 days. Celebratory activities include Chinese New Feast, firecrackers, giving lucky money to children, the New Year bell ringing and Chinese New Year Greetings. Most of Chinese people will stop the celebrating in their home on the 7th day of New Year because the national holiday usually ends around that day, however celebrations in public areas can last until the 15th day of New Year.

It is the money given to kids from their parents and grandparents as New Year gift. The money is believed to bring good luck, ward off monsters; hence the name "lucky money". Parents and grandparents first put money in small, especially-made red envelopes and give the red envelopes to their kids after the New Year's Feast or when they come to visit them on the New Year. They choose to put the money in red envelopes because Chinese people think red is a lucky color. They want to give their children both lucky money and lucky color.
