是什么原因导致失眠呢?失眠吃什么比较好呢?

现在的生活压力比较大，很多的人会出现失眠的症状，失眠对于健康产生一定的影响，其实对于睡眠质量差，在饮食方面是可以促进睡眠的。

那么，是什么原因导致失眠呢?失眠吃什么比较好呢?下面就来讲讲失眠的原因有哪些吧。

失眠的原因有哪些

行为因素

不良的生活习惯，如睡前饮茶、饮咖啡、吸烟等，经常日夜倒班工作，以及长期夜间作业，流动性工作如出差等，都可以使睡眠规律改变而引发失眠。此外，生活无规律，入睡无定时，过度娱乐，以及跨时区的时差反应等，均可以引起体内生物钟节奏的变化而出现失眠。另外，饮食过饥过饱、疲劳兴奋等，也可引起失眠。

年龄因素

失眠与年龄密切相关，年龄越大越容易失眠，老年人入睡时间往往较长，加上夜尿多，睡眠浅，易醒等原因，因此老年人失眠的发生率比年轻人要高得多。

疾病因素

任何躯体的不适均可导致失眠，失眠与很多疾病有关，或者说有不少疾病会引起失眠。失眠往往是一种表象，其背后常常隐藏着其他疾病。如神经衰弱、精神分裂症、情感性疾病、绝经期综合征、甲状腺功能亢进、肺源性心脏病、过敏性疾病、中枢神经系统疾病、高血压病、膀胱炎、女性生殖系统疾病、冠心病、营养不良、糖尿病等。

精神因素

精神因素是引起失眠的主要原因。生活和工作中的各种不愉快事件导致焦虑、忧愁、过度兴奋、愤怒，持续的精神创伤导致的悲伤、恐惧等，均可引起失眠或者加重失眠。多数失眠者因为工作压力大，过于疲惫和思虑过多而阻碍良好的睡眠，患者因过分关注自身失眠问题而不能正常的睡眠，有时即使睡着了也是多梦易醒，出现恶性循环。

环境因素

是引发失眠的比较常见原因之一，居住环境噪杂、住房拥挤、卧具不舒适、空气污染或者突然改变睡眠的环境，噪声、强光的刺激，气温的过冷或者过热，以及蚊虫的侵扰都会影响睡眠而出现失眠。

药物和嗜酒因素

药物是引起失眠的另一祸首，有些失眠纯粹是由药物引起的，即药源性失眠。能引起失眠的药物常见的有平喘药、安定药、利尿药、强心药、降压药、对胃有刺激的药，以及中枢兴奋药等。另外，长期服用安眠药，一旦戒断会有戒断症状。偶尔饮酒可能有帮助睡眠的作用，但若长期饮酒，就像吃安眠药一样上瘾，久而久之将影响正常睡眠。医生建议用药一定要注意其副作用，治疗失眠可以用中药调理，像安神补脑液、安舒汤等。

就睡着了。

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.
