Hey there! Welcome to Life Noggin! Oh there's a fog rolling in! Wait a minute! That's not fog!
大家好，欢迎来到大脑洞开的生命奇想！奥，这里有雾滚滚而来！等一下，这不是雾！
People have been using cannabis as a sleep aid for decades, mainly due to the feeling of relaxation and calm it's commonly associated with.
人们使用大麻作为安眠药已经有几十年了。这主要跟大麻带来的放松和冷静的感觉有关。
And many believe that it can even help with sleep disorders. Studies evaluating the effect of cannabis on sleep go back to the 70's,
而且很多人认为大麻可以帮助改善睡眠障碍。评估大麻对睡眠影响的研究可以追溯到70年代，
but, because marijuana use has been illegal in the United States since the 30s, research in this field has been largely restricted,
但是，由于自30年代以来，大麻在美国一直是非法的，所以这一领域的研究在很大程度上受到了限制，
and we are still lacking verifiable evidence of its effects on health.
我们仍然缺少它对健康影响的可证实证据。
But scientists have been studying its main chemical components for the treatment of many medical issues,
但是科学家一直在研究大麻的主要化学成分对很多医疗问题的功用。
like the nausea caused by cancer treatments, seizures in children, pain and different sleep disorders.
比如由癌症治疗导致的恶心，儿童的癫痫，疼痛和不同的睡眠障碍。
Before we get into how it affects your sleep, we should probably talk about how it all works.
在我们探究它是如何影响你的睡眠之前，我们应该谈论这一切是怎么运作的。
What we call weed, pot, or marijuana is actually a mixture of the dried flowers of the Cannabis sativa plant.
我们所说的烟草、大麻实际上是大麻属植物的干花的混合物。
It can be smoked, vaped, brewed in teas, made into foods, or concentrated into resins and oils.
它可以做成烟、电子烟、泡在茶里、做成食物，或者浓缩成树脂和油。
No matter how you take it, the chemicals in the plant will make their way into your bloodstream, travel throughout your body, and end up in your brain.
不管你怎么服用，这种植物中的化学物质都会进入你的血液，在你的身体里传播，最后进入你的大脑。
How fast you feel the effects and how strong they are depends on the method of ingestion.
你感觉效果有多快，效果有多强，取决于摄入的方式。
And your experiences can range from relaxation and euphoria, to anxiety, fear and panic depending on how much you take and the potency of the drug's active chemicals.
你的经历可以是放松和欣快，也可以是焦虑、恐惧和恐慌，这取决于你服用的剂量和药物活性化学物质的效力。
Some who have taken large doses have even experienced a temporary psychosis, including hallucinations and delusions.
一些服用大剂量药物的人甚至经历过短暂的精神病，包括幻觉和妄想。
So it's really, really important to be careful with how much you're taking and how.
所以非常非常重要的一点是要注意你服用了多少，怎么服用。
And cannabis use has been associated with harmful side effects on brain development and the lungs.
此外，吸食大麻还会对大脑发育和肺部产生有害的副作用。
The main chemical in cannabis is delta-9-tetrahydrocannabinol - but you can call it THC.
大麻中的主要化学物质是德尔塔-9-四氢大麻酚，但你可以叫它THC。
THC is a psychoactive chemical, which means that it can alter your mind.
THC是一种精神活性化学物质，这意味着它可以改变你的想法。
It does this by attaching to neurons in your brain and activating them.
它通过连接到你大脑中的神经元并激活它们来做到这一点。
This disrupts normal mental and physical functions, causing the sensations typically associated a "high".
这会破坏正常的精神和心理功能，引起的感觉通常与“兴奋”有关。
Cannabis also contains another chemical that is not psychoactive, called cannabidiol, or CBD.
大麻还含有另一种不具有精神活性的化学物质大麻二酚，简称CBD。
Older studies looking at the effect of the whole cannabis plant on sleep had mixed findings, with some indicating that it can help you fall asleep faster and stay asleep,
以前的研究着眼于大麻对睡眠的影响，结果有好有坏，有些研究表明它能帮你睡眠更快，睡的更久。
and others showing it can decrease REM sleep, - which is thought to be involved with storing memories, learning, and regulating your mood.
其他的研究则证明它使快速眼动期减少，快速眼动期被认为和记忆储存、学习、调节情绪有关。
More recent studies focus on these major chemicals in cannabis, THC and CBD.
更多最近的研究专注于大麻的主要化学成分德尔塔-9-四氢大麻酚和大麻二酚。
They found that THC may only have a short-term benefit, with continuous use causing a habit or dependency, as withdrawal from the drug can cause difficulties sleeping.
他们发现大麻二酚只有短期的益处，持续使用会导致习惯或依赖，停药会导致睡眠困难。
Studies also found that THC caused daytime sleepiness and bad moods, increased the time to fall asleep,
研究还发现THC会导致白天嗜睡和心情不好，增加入睡时间，
and reduced the body's circadian rhythm - which is needed to regulate your sleep/wake cycle.
损害身体的昼夜节律——这是调节你的睡眠/觉醒周期所必需的。
However, medicines made from it could help with certain sleep disorders like nightmares associated with post-traumatic stress disorder and obstructive sleep apnea.
然而，由它制成的药物可以帮助治疗某些睡眠障碍，比如与创伤后应激障碍和阻塞性睡眠呼吸暂停有关的噩梦。
It's clear that more research needs to be done before any definitive conclusions can be made.
很明显，在得出任何明确的结论之前，还需要做更多的研究。
But, until then, it may be better to stick to natural sleep methods like avoiding caffeine, exercising, and keeping a regular sleep schedule.
但是，在那之前，坚持自然的睡眠方法可能会更好，比如避免咖啡因、锻炼和保持有规律的睡眠时间。
So is there another drug you want me to talk about next? Any sleep-related questions you have for me?
接下来还有什么药你想让我讨论吗？你有什么关于睡眠的问题要问我吗？
Let me know in the common section below. Curious to know what happens when you go to sleep drunk? Check out this video!
请在下面的公共部分告诉我。想知道喝醉酒睡觉时会发生什么吗？请看看这个视频!
In general, it's not a good idea to use alcohol as a sleep aid since it's thought to ultimately lead to restless nights.
总之，把喝酒作为帮助睡眠的方式并不是一个好主意，因为这种方式最终会导致失眠。
One study found that clinical investigations seem to support a relationship between sleep disturbance and alcohol use.
一项研究发现，临床研究似乎支持睡眠障碍和酒精使用之间的关系。
As always my name is Blocko, this has been Life Noggin, don't forget to keep on thinking!
我是宝高，这里是脑洞大开的生命奇想。思考不要停！
