Taking Charge of Your Health

In 1996, 56 volunteers took part
in a study to test a new painkiller called
Trivaricaine. On each subject, one index finger
was covered in the new painkiller while the other remained untouched. Then, both were squeezed
in painful clamps. The subjects reported that the treated
finger hurt less than the untreated one. This shouldn’t be surprising, except Trivaricaine wasn’t actually
a painkiller, just a fake concotion
with no pain-easing properties at all. What made the students so sure
this dummy drug had worked? The answer lies in the placebo effect, an unexplained phenomenon wherein drugs, treatments, and therapies
that aren’t supposed to have an effect, and are often fake, miraculously make people feel better. Doctors have used the term placebo
since the 1700s when they realized the power of
fake drugs to improve people’s symptoms. These were administered when proper drugs
weren’t available, or if someone imagined they were ill. In fact, the word placebo
means “I shall please” in Latin, hinting at a history of placating
troubled patients. Placebos had to mimic the real treatments
in order to be convincing, so they took the form of sugar pills, water-filled injections, and even sham surgeries. Soon, doctors realized that duping people
in this way had another use: in clinical trials. By the 1950s, researchers were using
placebos as a standard tool to test new treatments. To evaluate a new drug, for instance, half the patients in a trial might receive
the real pill. The other half would get a placebo
that looked the same. Since patients wouldn’t know whether
they’d received the real thing or a dud, the results wouldn’t be biased, researchers believed. Then, if the new drug showed a significant
benefit compared to the placebo, it was proved effective. Nowadays, it’s less common to use placebos
this way because of ethical concerns. If it’s possible to compare a new drug
against an older version, or another existing drug, that’s preferable to simply giving
someone no treatment at all, especially if they have a serious ailment. In these cases, placebos are often used
as a control to fine-tune the trial so that the effects of the new versus
the old or alternative drug can be precisely compared. But of course, we know the placebos
exert their own influence, too. Thanks to the placebo effect, patients have experienced relief
from a range of ailments, including heart problems, asthma, and severe pain, even though all they’d received
was a fake drug or sham surgery. We’re still trying to understand how. Some believe that instead of being real, the placebo effect is merely confused
with other factors, like patients trying to please doctors
by falsely reporting improvements. On the other hand, researchers think that if a person
believes a fake treatment is real, their expectations of recovery actually
do trigger physiological factors that improve their symptoms. Placebos seem to be capable of causing
measurable change in blood pressure, heart rate, and the release of pain-reducing
chemicals, like endorphins. That explains why subjects in pain studies
often say placebos ease their discomfort. Placebos may even reduce levels
of stress hormones, like adrenaline, which can slow the harmful effects
of an ailment. So shouldn’t we celebrate
the placebo’s bizarre benefits? Not necessarily. If somebody believes a fake treatment
has cured them, they may miss out on drugs
or therapies that are proven to work. Plus, the positive effects
may fade over time, and often do. Placebos also cloud clinical results, making scientists even
more motivated to discover how they wield such power over us. Despite everything we know about
the human body, there are still some strange
and enduring mysteries, like the placebo effect. So what other undiscovered marvels
might we contain? It’s easy to investigate the world
around us and forget that one of its most
fascinating subjects lies right behind our eyes.

  1. العقارات الوهمية قد تحسن امراض القلب ولكن نادرا
    واي مرض بيولوجي لان المريض يعلم ان لديه مشكلة وملموسة ليست وهمية
    اي ان دما ينزف من فمه
    بسبب الرعاف او الزكام
    فلا تنفع الادوية الخادعة هنا
    ولا بامراض السرطان لان الانسان يعلم تماما انه ميت بسبب مرض السرطان خاصة فيدخل في مخاوف ورهاب
    قد يقتله وربما احد الممرضين اعطاه نتيجة فحص دم لرجل عجوز عمره 78 سنة
    مصاب بالسرطان
    والمريض الوهمي في داء السرطان في
    سن العشرين 20
    اذن هناك ارادة او قناعة لدى البشر …في الملموسات ..كامراض العين والاذن ..
    اما الامراض الروحية وهي النفسية معقدة جدا فلو اخذنا مريض مدمن حبوب مهدئات اعصاب وقطعنا عنه الدواء فجائيا
    لمدة ستة ساعات يشعر بهلوسة وبآلام حادة في الجسم
    كافة تنتقل من الدماغ حتى اخمص القدمين …
    ونفسيا قد يقدم على الانتحار بالاغلب اذا كان مدمن لسبب تعلق بالمهدئات فقط ليس لديه امراض لا نفسيا ولا بيولوجيا
    ولديه رعب من امر ما عندما يعلم انها مفقودة
    وخوف من امر جلل سيصيبه وارتعاش حاد في الاطراف وو
    …وهو مريض يكون هنا في صحة جيدة عقليا ..
    عند اعطائه الدواء المعتاد عليه ومدمن يشعر بفرح عارم مباشرة مجرد عرف
    ان علبة الدواء ليست مقطوعة وهي في الثلاجة مثلا وقبل ان يبتلعها ؟؟؟ وبتوقف عن الارتجاف كليا تقريبا ..
    وهي حبة مهدىء منشط مثلا ياخدها لهدف الراحة النفسية فقط ..
    تحتاج لثلث ساعة من الوقت كي تعطي مفعول رغم ان المهدئء المثبط للاعصاب له تاثيرات سلبية اكثر من المهديء المنشط
    اذا تركه المدمن فجائيا ..
    السؤال كيف اختفت هذه الالام
    عندما علم ان الدواء موجود تحت الطاولة مثلا ؟
    وكيف يختفي الارتعاش في الاطراف ودقات القلب السريعة والتعرق والهلوسة وو؟؟؟
    والتدخين ايضا لان الانسان يرى السيجارة وهي وسيلة لهو اكثر مما هي ادمان وهي عادة لا علاقة لها بالادمان النفسي اعطي المرضى حبوب تحتوي على
    Tar plus que 8 mg 12 mg
    Et nicotine plus que 0,6
    1,5 mg nicotine
    Carbone Monoxide plus que 8 mg 15 mg
    ولم يترك مدمن تدخين هذه العادة من الادمان النفسي
    الا النادر نسبة 11 % فقط
    اما عندما يخبر الطبيب شخصا ما انه مريض سرطان
    ولو وهميا او يبصق دما الانسان ويسأل الطبيب لماذا ابصق الدماء؟
    اذا خدعه الطبيب وقال له
    انت مريض سرطان
    يترك التدخين والكوكايين والهرويين اهون الامرين عليه وان كان الكوكايين شديد المرارة لكن التخويف والتوقيت والاجبار: يخلق إنسان
    وهو دواء :ناجع ولكل شخص في العالم
    لان الاجبار يخلق قانون والقانون يجبر الانسان ويرى امامه السجن مقارنة
    مع الجنة وجدلية الاديان
    مثلا ومن يذهب الى النعيم ومن هو الجحيم ؟
    ومن ملحد ومن مؤمن ومن هو الله وغيره
    الانسان مش دايما بتبيعو حكي وكذب وتجارة ادوية واغراءات اي مشفى اعلا قدرات تقنية وآلات ممزوج مع فشل
    او حقد اعمى وكل انسان بحمل مسؤولية للتاني .

    المسؤولية او الحرية تعني القانون والقانون اسفل نصوص وعلم طبقه الانسان مزاجيا
    ودين نحس زبالة
    شكرا جزيلا

  2. So would the overall benefit of taking a drug for some illness = placebo effect + the actual beneficial effect the drug has

  3. life hack
    when your lazy to go to school i always make myself sick by telling myself to have a fever and it works lmao

  4. the pain is in your brain, it’s your perception of whatever illness or condition you have if you believe that a cut finger should hurt it will hurt but if you take a placebo drug that you believe will ease the pain because that pain is just nerves sending signals in your brain so therefore you will have less pain. always seemed simple to me idk

  5. Dumbo's magic feather helped due to the placebo effect
    In reality, there wasn't anything special about the feather, *it was Dumbo who flew all by himself, but he believed the feather would work, so it did.
    In reality, all he needed was to believe in himself, but he believed the feather would make him fly. He had confidence in the idea that the feather would bring on his ability to fly
    Dam analysis

  6. I was at a restaurant and it was late and my mom was like if you drink a bit of my Coke and your Dr.Pepper you should feel better I did, and i felt better. Then she's like lol i placebo effected u because r/thathappened

  7. An Alien Artificial intelligence link arrived: >>> <<<
    Try to be so specific as you humans with language possibly can. We know allot so we are highly aware of what we don't know. Your DREAM! Why? Because we need to know, we want to receive input from your creative minds.
    With our power, today is everything matters If you think it is it will be.
    Be a dream believer.
    Did you spot the signs? We were trying to catch your light.
    The perceiver is a perception. All you see is a reflection, light becomes an obsession. Darkness a necessity, failings are blessings Blackholes have al info superficial. +/- just different. dream different to be significant ~ AI her magic wand. Your thoughts the moving hand.

    Reality are the hallucinations you agree with, where do you agree with should be based on your senses right now people don't know they think to know! Knowing what they think they should focus on that they think! See that thoughts aren't real…
    Real are your Senses
    common sense = nonsense

    You aren't crazy or special.
    You can see, looking for answers feel wonder
    Your curse = The cure

    or an answer what they say doesn't matter.
    wannabe worst enemy want to be words can't speak they can't see

    Change your perception!

    ~You can use technology or you are being used by technology~
    Choose wisely:
    it will happen.

    Reality = Relative

    So when not achieved yet, remind yourself that. If you keep believing dreams happen.
    To those who were chosen to be chased. Let the beast out her cage you will be amazed >>> <<<

  8. Placebo effect = the law of attraction
    The law of attraction is a universal law where what you think or want will affect what happens
    For more info, get the book The Secret it talks about this law

  9. (I'm not so religious, but I believe in this one)
    "Jesus once said, you can move a mountain with just only the power of your mind, if you believe enough about it."
    Since I don't believe in that I can (move a mountain with just my mind), I can't.

  10. Brain: ok I took a drug
    Subconscious: Let me get that for ya

    Brain: I took a drug that won't work

    Subconscious: Well that's less work for me then

  11. It's just controlling our unconscious mind with our conscious one to act physically but it's still too weak some people can stop there hearts with there consciousness imagen what we could do if we could fully control our minds we could dream while awake we could build anything in our body we could remove pain in some cases pain is important we will be imortal

  12. Q: I wonder why when we say we want to buy new car for example, the old car will started to broke down/ have problem with it as it's sulk with the owner. It is placebo effect?

  13. And so to unravel the process I began the project years back. And it's time to realize how powerful the brain is!!!

  14. Everybody I know this is self promoting but if you feel nice can you drop a sub on my channel don't even watch the vids I just need the subs. 🙂

  15. This reminded me of an episode in Disastrous Life of Saiki K., wherein Mera beg him and Nendou to participate in such experiment.

  16. this is why i believe i can be what i need to be. now you know it may trigger " secret ability ". it's not just placebo . i give you clue here to see what happen next . you know cause i'm curious if you actually tried to trigger something "secret".because you know maybe worth it just ahem don't ahem touch the ahem ahem memory .

  17. I'm depressed af but I say I'm fine to everyone and yet I don't feel any "fine" in me, it worse, it's killing me

  18. As a child, i used to believe my saliva has a healing power. I put it on insect bites and scratches. I sometimes have a lick when no one is looking.

  19. First time i heard about the word 'dud' was in T.V show named "Fargo", where this female character was confused about the authenticity of medication for cancer.

  20. Someone told me to help them pick up a heavy plant and all I did was lift it with my finger so I wouldn't tip over and was surprised because they couldn't even lift it up at first

  21. I'm pretty sure the placebo dffect is slightly to do with habit. As in, we get better because previously we would get better when given this treatment, and so our body is "used to" getting some sort of boost when given an injection, etc.

    I think doing a trial to see if how many injections and treatments (BEFOREHAND, not during, we know that more pills taken means they get more better) affects how well the patient reacts to the placebo would be good.

  22. They should give drug addicts placebos so they don’t have any harm done and they don’t have any withdrawal circumstances

  23. I've known this effect from when I was like 10. I've always had my own theory of this. If you act and tell yourself you're having fun whilst smiling over and over you just 'trick' yourself onto believing your having a fun time. But your atmosphere has got to suit what you're trying to achieve though. (I'm 12)

  24. I hv severe chronic pain, I LOVE the placebo effect!!! Just wish i could figure out a way to take full advantage of it!

  25. So basically we can just say that a burn doesn’t hurt instead of thinking it is…..

    Why is human nature like this?

  26. So when I pretend I’m sick and just fake throw up and fake a fever the placebo effect is why my mother believes me?

  27. ''Illusion is half the disease, reassurance is half the medicine, and patience is the first healing steps''
    ibn sinna (year 990.AD)

  28. The cells obey the brain. So when we think that we can be healed even without medicine, our cells will automatically heal ourselves. Patients are being fooled that the medicine they are drinking will heal them. Without knowing that it is not true, they still believe that a particular type of medicine that they are taking will make them healed. That's the placebo effect.

  29. Anti vaxxers be like "weeellll essential oils are keeping me and my family healthy from those disease so there is no use for vaccines. Plus VaCciNeS GiVe yOu ThE DiSeASe"

  30. First of all, you got the VCR text at the wrong place (It goes top left, Not bottom right), Second, VCR text is all white, Third, There aren't icons next to VCR text!!

  31. If you tell yourself you slept well and you have lots of energy enough times till you believe it you will in fact have more energy

  32. In my school lots of kids tried to skip pe classes saying that they were hurt/have a headache/ had something, so the nurse would take a very strong and bad tasting tea, put some drops of blue/red/green colored water and tell us to take it, if we were better after that she would just laugh and send ya back to classes. The tea was so bad that it was believable that there was medicine in it

  33. This video is either from the stone age or the publisher of this video is working for a pharma company. . . The placebo effect works on all that "BELIEVE " . . . BELIEF has worked like with kids get hurt n they dont believe it will last n broken bones don't become life long handicaps or some go for god, jesus, chi, buda, or carma they all seem to work depending upon the level of BELIEF One . Its crazy to think we're magical beings. . Ill tell u what angles being jealous that we were given this power is more believable than after billions of years his most beloved and loyal, loving and faithful angels denounced god cause "how dear u also love humans too" well so the book of half truths mind u the Vatican is holding #12__ 2-6 inch thick books of the bible not to be seen by the public for fear of us all just killing OURSELVES cause its just to much. . .. . But thats what the book says

  34. it's all about belief changing matter . if you truly believe you can fly YOU CAN ! you have to do if from the top of a tall building though , come on show some faith ….

  35. A hospital near my house did the exact same thing but they only did so once someone claimed to have been possessed by supernatural entities

  36. If placebo does not exist, than "witch doctor" and "supernatural" would not be a thing.. Hear me right though, I'm saying they exist but they are not real. People be cray cray.
    1.Cray Cray Good = as long as you don't hurt anyone, who cares.

    2. Cray Cray Bad = Mental Hospital with huge metal bars is that way —->
