北京瘙痒| 这些比较意想不到的瘙痒的原因

很多的人都会有瘙痒的困扰，瘙痒的原因也有很多。

今天北京华科就为大家介绍一些比较意想不到的瘙痒的原因。

月圆

月圆之夜人会失控变成狼人只是个传说，但它却有可能让你心绪不宁、辗转难眠。瑞士一项研究发现，在月圆的前后4天，睡眠质量会变差，包括总体睡眠时间减少20分钟、深睡眠时间减少1/3、褪黑素生成减少而使人们更易感到疲劳。针对这个原因目前并没有特别好的解决方法，但至少你了解后就不会为月圆时轻微的睡眠问题感到焦虑。

缺乏运动

近期西北大学一项睡眠研究发现，运动的确可以提高睡眠质量，但这并非立竿见影。瘙痒症患者可以通过生活方式改变、坚持锻炼来改善睡眠，这通常需要2~4个月才能有明显的效果。也就是说，你不能早上刚运动完，就指望晚上能睡个好觉。根据美国疾控中心推荐，运动时间比较好能达到每天20分钟以上，或是一周累计运动时间达到两个半小时。

枕头太热

北京华科：躺在稍凉的枕头上有助于降低核心体温(即身体内部的温度，比体表温度略高)，更容易产生睡意。匹兹堡大学曾做过一项研究，给瘙痒症患者带上一个特殊的降温头套，他们平均在13分钟以内就能入眠，而睡眠正常的人平均需要16分钟入眠时间，并且89%的受试者都能睡一整晚好觉。研究人员推测，给大脑适度降温可以减慢新陈代谢并使内心更加安宁。睡觉前不妨把枕套适当冷却一下，你可能会睡得更好。

服用新药

很多药物都有导致瘙痒的副作用，包括降压药、抗抑郁药以及类固醇类药物。此外，服药时间对睡眠也有影响，例如某些高血压或心率失常患者需要服用受体阻断剂(如阿替诺尔、美托诺尔等)，通常医生都会建议把服药时间定在早上而不是睡觉前。因此，在开始服用新的药物前，一定要向医生问清楚比较好的的服药时间。

宠物上床

即使对宠物不过敏的人，当床单、枕套上沾上宠物皮屑或毛时，也可能觉得不舒服，这是因为它们可以导致鼻腔黏膜充血，从而更容易打鼾，使人难以入眠或睡不安稳。梅奥诊所曾做过一项关于睡眠障碍的调查，超过一半与宠物一起睡觉的人，表示宠物会扰乱他们的睡眠。如果你怀疑自己瘙痒可能和宠物相关的话，就比较好就不要让它们在卧室玩。

Death by Insomnia

Talk about insomnia on the Sleep Disorders Exchange

Is it really true? Can you die from sleeplessness?

If you happened to watch the National Geographic Channel last month, you might have caught sight of a special on Fatal Familial Insomnia (FFI) — a deadly form of insomnia that runs in some families.

Don’t panic. This condition is extremely rare, so rare that it has just been named and is currently under study around the world. It is only known to be in 40 families, affecting about 100 people worldwide. What we know about this disease is:

The disease is based on a protein abnormality, when a protein called a prion attacks the thalamus.

It’s genetically inherited and passed down through generations.

The first sign of FFI is sleeplessness, followed by continued insomnia with hallucinations and panic attacks, progressing to total insomnia and weight loss, which then progresses until the victim is so sleep deprived that his or her systems shut down until death occurs.

In one particular case (chronicled on the television program), a man developed the disease in his fifties after having slept pretty well throughout his life, which is common for this disease.

Then his troubles with sleep snowballed to the point where his body wouldn’t let him rest. He died within months.

Stories like this remind us that sleep remains a mystery still waiting to be fully understood. But the average person doesn’t carry the gene for FFI and will have a hard time (impossible, really) sleep depriving him or herself to death. Remember, there only 40 families known in the world that have FFI – and it is certainly heartbreaking for those families. But what this tragic illness shows us is the most severe effect sleep deprivation can have on the human body.

It is true that the research shows that consistently sleeping fewer than 6 hours a night increases your risk for a variety of diseases such as colon cancer, breast cancer, heart disease, obesity and diabetes (and perhaps getting run over by a bus because you can’t focus or pay attention). Lack of sleep can lead to poor health – but you are not going to be able to intentionally sleep deprive yourself to death.

According to The Guinness World Records, Randy Gardner set the record back in 1964 when as a 17-year-old he went 11 consecutive days (264 hours) without sleep. After staving off sleep for a few days with cold showers, playing basketball and listening to loud music (not to mention media reporters and games of pinball), he could no longer focus his eyes and had to give up TV. His speech slurred, and he fell into a silent stupor.

But he didn’t die soon after. And he did sleep more than usual for a few nights when he finally went to sleep.

We now believe that long sleepless stints like Randy’s can be dangerous. He appears to have paid back his sleep debt by getting extra sleep for a few nights. And remember, he was a teenager.

The moral of the story: You can go for a period of time without quality sleep, and experience the consequences. And you can recover if you allow your body to recoup those lost hours again. But regularly and consistently failing to get the sleep your body needs is just plain unhealthy, and will have long-term consequences on the quality of your health and your life.

And please don’t try to make into the Guinness World Records by breaking Gardner’s record. Guinness doesn’t keep records for voluntary sleep deprivation anymore – they decided it was too dangerous.
