Two Simple Tests for Adrenal Fatigue

Hey guys, Dr. Berg here. In this short video we’re going to show you
two different simple home tests that you can do for adrenal fatigue. All you need is a flashlight. Number one, the holding your breath test. Now one good indication of adrenal fatigue
is the ability to hold your breath for long periods of time. If you can’t, you probably have an adrenal
issue, because the oxygen in your lungs is connected to the adrenals, and so if you have
really good adrenals you can hold your breath for like a minute or longer. There’s a guy who came to my office who is
80 years old. He had the best adrenals I’ve ever seen in
my life. He can heal real fast and I have a machine
that measures the adrenals and he had a perfect score. I asked him, “What did he do his whole life?” Well, he took first place in the Olympics
when he was like 20 years old for water polo, and he was able to hold his breath for at
least three to four minutes, so he can actually hold his breath now for three minutes underneath
the water, so his adrenals are really tough. You have adrenal case, they’re huffing and
puffing. Up stairs, they run out of air real quick. They cannot hold their breath. That’s the first test. Number two is the iris test. Now what is the iris? The iris is kind of like the aperture of the
eye. Now what is an aperture? Aperture is just a opening in the camera that
allows the light to go in at a certain level, so this is the same thing. If there’s a real bright light, the iris contracts
and constricts the amount of light going into the eye because it might be too harmful. If it’s dark out it actually is very, very
open. It controls the light. If I’m going to shine a light into the eye
like this, this thing normally should contract. Now what’s controlling that is something called
the autonomic nervous system or the sympathetic nervous system. What is that? That’s part of the nervous system that is
intimately involved with flight or fight and the adrenal. The adrenals control that. Other parts of the body control it, but the
adrenal gland is also involved, so if there’s a weakness with the adrenal and you shine
a light into the eye, what’ll happen, it’ll contract, it’ll constrict, but it will not
maintain that constriction, so it might kind of hold it for about five seconds or ten seconds
and it starts going … It actually fluctuates. It kind of comes open and close because it
cannot hold that constriction. If you can hold that constriction and keep
this thing constricted for at least a minute, then your adrenals are good, so it’s a real
simple test. In this next part I’ll show you exactly how
to do a little demo of how to do it. Okay guys, the first thing we’re going to
do is we’re going to shine a light into the eye, and if you see the little black part
in the center, that’s the pupil. That’s the hole right into the eye, and then
the other part, which is kind of the colored part, that’s called the iris. That’s contracting, constricting, and relaxing. When that contracts it makes the pupil, the
little center part, get smaller or larger, depending on what’s happening. When you shine light in there, normally the
iris, the outer part, is supposed to contract and hold that position for at least one to
two minutes. If that contraction cannot occur, that means
the adrenal glands are weak, and you’ll start seeing the pupil get bigger and small like
a wave, like it will not be able to maintain the very tight contraction. You just do this in the mirror. Look into the mirror, shine the light into
the eye. The small little pupil should get smaller
and maintain that smallness by keeping the light held steady. If it starts to get weak and start to open
up, which a lot of times it will within about, I don’t know, 10-15 seconds, then we know
the adrenals are weak because the entire nervous system that controls that is weak. Okay guys, so now that you have a way to figure
out your adrenals then the question is what do you do about it? There’s a great little kit that I have to
help the adrenal glands. I put the link below. Check it out if you want some help. Thanks for watching.

    Is adernal fatigue cause heart palpitation

  2. Brad Patten Posted on November 7, 2018 at 9:46 am

    Too bad adrenal fatigue isn't supported by peer reviewed scientific papers. It is supported by the vitamin industry.

  3. Masteraster Posted on November 15, 2018 at 4:56 am

    what a load of crap

  4. TheFly212 Posted on November 17, 2018 at 5:05 am

    Hey Doc, got a question. My left ear is hit and red, all day everyday. My Primary Care physician said I have Roscacea. I've been on the meds but my ear still gets real hit and red. Only my left ear. Sometimes my left upper cheek will get hot and red. But my left ear is always hot.

    Could this be adrenal issue?

  5. Cristina Cervi Fitness Posted on November 17, 2018 at 3:41 pm

    very interesting

  6. craft Cooke Posted on November 17, 2018 at 10:14 pm

    If you buy the book the medical medium by Anthony William it gives you loads of information and what to do I have just now bought the book very interesting indeed

  7. NationalSi Posted on November 18, 2018 at 7:59 pm

    What is the adrenals? Couldve explained that to us first,I dont know what you mean.

  8. rob dog Posted on November 19, 2018 at 6:46 am

    From other vids I've watched this ' doctor ' only responds when you show interest in parting with money 💰

  9. Blessed Bayers Posted on December 9, 2018 at 3:06 am

    Hey Dr. Berg, I can't get to a Sauna (busy mother of eight here) but I am wondering if sweating in a hot bath with some Epson salts could be a good way to detox.
    I have overcame adrenal fatigue before and I have great faith I will again! I'm so thankful for God's wisdom! God bless you!

  10. Magdalena Luchter Posted on December 10, 2018 at 5:16 pm

    The adrenal kit is not there anymore …

  11. Lauretta Posted on December 11, 2018 at 1:23 am

    When I began having severe adrenal fatigue, my iris was doing that even without the torch in my eyes. It just did that in daylight. Doctors didn’t understand it and thought it was my imagination. Doctors need to be more educated! Also I could never get a deep breath of air or hold my breath either.. amazing knowledge Dr Berg

  12. Anthony J. Posted on December 13, 2018 at 3:01 pm

    Confused people in the comments: the girl in the video does NOT have adrenal fatigue. Her pupils remaines contracted.

    I have very bad adrenals. With the test, my pupils stay dilated, and I mean very dilated no matter how much light I shine in them, they almost take up the whole iris.
    I can't open my eyes outside because light hurts me, and my stupid iris won't contract.
    Also, I can never sleep more than 3h to 4h a night, IF I even sleep at all.

  13. Sapience Success Posted on December 15, 2018 at 12:32 pm

    Wonderful! Thanks – really helpful!

  14. A E Posted on December 20, 2018 at 2:40 pm

    The Pupil….not the Iris contracts…..

  15. Linda Burchell Posted on December 26, 2018 at 10:28 am

    Make sure your not low in vit d or magnesium. Take a mulri w/rda with no iron. Thompson's no iron daily multi is a good one from vitacost online.

  16. AnnaRose LaRue Posted on December 31, 2018 at 3:09 pm

    Okay guys. Dr. Berg made an error here, bless his heart. He DID mean the pupil contracts, NOT the iris. Think of the iris like a colored flower – blue, green, brown, etc. Think of the pupil as the little black guy in the center who can't stand still depending on the amount of light. When you flash him he contracts (yikes!), but at night he enlarges to be able to let in more light to see (like a cat). Check out your cat if you have one.

  17. aj aj Posted on January 3, 2019 at 3:13 pm

    Your accent is so good sir😍

  18. aj aj Posted on January 3, 2019 at 3:16 pm

    I can hold breath for 1min 16sec😁

  19. Chris Posted on January 11, 2019 at 2:21 am

    I was at the drugstore and used their machine to measure my blood pressure. It gave me a printout, which I took home to my brother-in-law, who works in the hospital lab. He saw my numbers of 98 over 60 (if I can recall correctly) and immediately asked me if I felt ok? I laughed and asked him the same question. I've always been low. I have a lower than 'normal' body temperature too…so, I guess my fever would be another person's normal. Anyway, I wear sunglasses, but, my eye doctor said, it's typical for a blue-eyed person to be light sensitive. No doctor has ever had an issue with my blood-pressure… except a 'newbie' who worked under my regular doctor. I warned her that my numbers are low… she rushed out of the room after taking my blood pressure. My doc came in and saw it was me and said, 'ya. she's fine.' lol
    I tend to literally jump out of bed, after sleeping, as if there's a fire. This has made me fall to the floor, on my butt, and sometimes I hit my head against the wall or door, too. I've learned to just sit on the edge of the bed for a minute… to let the blood get to my head, I guess. Dizziness truly sucks. It slows me down… you know… to put out the fire I was rushing to. lol
    Thanks so much for explaining this. I held my breath for 1 minute and 17 seconds and could have gone longer. So, ya..I'm fine. I'll outlive everyone. Both my grandmothers were in their 90s when they decided to stop holding their breath. Thanks again.

  20. Wayne Varrelman Posted on January 12, 2019 at 10:09 am

    Bad tests for adrenal fatigue. Most thyroid or adrenal glands can be controlled by diet. But if your really concerned go to and endocrinologist.

  21. A- Shotter Posted on January 18, 2019 at 5:31 am

    0:01:34 while completely still(0:02:10 only once motionless) Adrenal fatigue?

  22. Lilith Rose Posted on January 18, 2019 at 9:38 pm

    You’re so smart. Love it 😍

  23. avi gold Posted on January 21, 2019 at 12:54 am

    well I have severe asthma and your holding your breath test is not going to work for me

  24. Andrew Posted on February 4, 2019 at 2:52 pm

    For the pupil test, I don't even need to shine a light into them, they are still for a little bit and then all over the place. Is this adrenal fatigue as well?

  25. Jezza Lenko Posted on February 5, 2019 at 12:20 pm

    Nothing like a bit of self-diagnosing…. 😕

  26. Michelle My Belle Posted on February 9, 2019 at 4:23 am

    So the test some law enforcement officers use to check for DUI could be adrenal fatigue. Interesting. I wonder if the 3 people who never did drugs in their lives, who failed that test and were arrested actually have adrenal fatigue? Man, I should have been an attorney instead of….

  27. Annette Fowler Posted on February 14, 2019 at 6:24 am


  28. Kathleen Walsh Posted on February 17, 2019 at 7:57 am

    I can hold my breath for 45 seconds but my pupils fluctuate immediately

  29. coriander zvx Posted on March 2, 2019 at 6:26 am

    wow i have never been able to hold my breath long , since childhood. makes sense , i think my adrnals have been burnt out since age 13. lots of trauma/illness/anxiety. just timed myself…35 seconds until it felt impossible

  30. Akshay pillai Posted on March 3, 2019 at 8:27 am

    I can hold breath for 2 mins 18 sec straight without any panic…

  31. Jordan Beveridge Posted on March 7, 2019 at 2:45 pm

    There is no scientific evidence that adrenal fatigue exists at all and this should not be confused with an actual medical condition

  32. LEZLIE WIAZOWSKA Posted on March 13, 2019 at 9:15 am

    The food is not food anymore. It does not even smell most of the time the way fresh fruit and vegetables should. I am so tired of being in a counterfeit system of everything.

  33. Abilio Arruda Posted on March 14, 2019 at 2:18 am

    Is one hour good??

  34. Kateri Tekawidthá Posted on March 17, 2019 at 4:11 pm

    For human ppl, with very little money here you go.
    Use B5 500mgs  and C -1000 mgs do this 3-5 times a day,also use gelatin broths with egg and if you can blend some cottage cheese in a blender and add a little yogurt or kefir and MSM if  you have this,make sure you are using digestive enzymes as well and no breads pastas rice corn cereals breads –ALL kinds including the genetically engineered gluten  free and no barley oat buckwheat quinoa  or millet or any other type of pseudo grain,alot of this is toxic there is no organic
    avoid anything with silica
    To all of our health and survival.✊😎❤🌏⚚⚛
    Love💛 & Light☄

  35. Sylvain Riendeau Posted on March 28, 2019 at 5:06 pm

    Thank you.

  36. Guy Austin Posted on March 29, 2019 at 7:16 pm

    everyone here is crazy

  37. Awilda Garcia Posted on March 29, 2019 at 10:21 pm

    Hi, I've had a kidney transplant for more than 15 years and need to keep taking prednisone for the kidney. Having this many years of this steroid, how can I successfully do keto?

  38. Rajshree Shah Posted on March 31, 2019 at 5:44 am

    Can you please make a video on hypothroidism? Diet and supplements. Thanks

  39. MizzBee13 Posted on April 4, 2019 at 9:27 pm

    Well, if you have asthma then most likely you also cant hold your breath!

  40. Four Horsemen Posted on April 9, 2019 at 3:46 am

    I had Adrenal Fatigue for 7 years. I failed both these tests constantly until yesterday. My adrenals are finally healed!!!! Unfortunately I had to quit my job and rest and I'm afraid not many people have that luxury so I feel very sad for people who suffer from this condition and are forced to keep on going. Get Dr Berg's kit and cut out gluten, meditate, do yoga, go on retreats, eat healthy and change jobs, do what you need to do but adrenal fatigue is hell on earth.

  41. Rachel Rachel Posted on April 10, 2019 at 5:39 pm

    I failed both test miserably😔

  42. G A Posted on April 11, 2019 at 10:27 am

    Thanks Dr.Berg you make my life happy 🌻

  43. laura dobric Posted on April 14, 2019 at 6:34 pm

    Where is dr. Berg ,s office?

  44. Benjamin Payzant Posted on April 17, 2019 at 9:16 am

    I was able to hold my breath for 2 minutes so I guess I just need to consume more and healthier food.

  45. Andreina Gil Ramirez Posted on April 19, 2019 at 4:44 pm

    This is so fake. Pulmonary capacity has nothing to do with adrenals, so is pupillary/consensual reflect. You don’t give any biological explanation to its relation. And adrenal fatigue is not a scientifically demonstrated condition. Please stop fake science.

  46. trebelclef Posted on April 30, 2019 at 11:44 am

    A machine that measures the adrenals? Hum, a test using ACTH is the only measure that assesses adrenal cortisol output. 24 hour urine only measures that day.

  47. Natalie Richmond Posted on April 30, 2019 at 9:19 pm

    so i held my breath for 59 seconds! gonna try the second test..i did cortisol tests and the lvl was high so my doctor suggested an Xray of

    pituitary gland..? i never did it though. i am stressed and i can never have a moment of silence as my mind always brings up something .

  48. 1Deceived 2ManyTimes Posted on May 2, 2019 at 4:39 pm

    Wow! My pupil contracted and retracted in waves under my phone torch

  49. Elvis Edge RR Woodward Posted on May 3, 2019 at 9:24 pm

    Adrenal fatigue tests

  50. IdolEyes84 Posted on May 6, 2019 at 3:09 pm

    When I put my phone's torch light up to my eyes, my iris' do the same as the demonstration. They go small, and then get a little bit bigger and small again just like hers. Is that a GOOD sign? Does that mean I don't have any adrenal fatigue problems?

  51. Karin Brown Barrios Posted on May 7, 2019 at 3:18 am

    If I can't afford the kit will the adrenal supplement only help?

  52. Oleg Kruk Posted on May 10, 2019 at 12:33 pm

    This test needs to be done i dark room ?

  53. Terrence Deosarran Posted on May 10, 2019 at 5:20 pm

    Thanks again Dr.Berg

  54. Lulu Labelle Posted on May 11, 2019 at 7:30 pm

    I've never failed an adrenal fatigue test. Wish that counted at school 😁 but seriously, do you think it's possible for someone to recover after about 3 decades of AF?

  55. Chan Valentine Posted on May 12, 2019 at 5:03 am

    Well my adrenals are shot to hell…good thing I'm seeing and endocrinologist.

  56. EpicMeme Productions Posted on May 17, 2019 at 6:02 am

    Thank you very much Doctor Berg
    Going to try this tomorrow since I'm in bed already. Thank you!!

  57. Dass e Posted on May 18, 2019 at 10:41 pm

    Learned nothing on how to correct the issue. Something about a kit but I've no idea what he's talking about

  58. M Morrok Posted on May 25, 2019 at 10:54 pm

    You're legendary educational.
    Even though I may not have certain issues I just enjoy learning from Ü, Dr Berg.
    My curiosity is insatiable.

  59. M C Posted on June 4, 2019 at 1:02 pm

    Where is the link on how to fix adrenal!?

  60. jewqueen E Posted on June 13, 2019 at 9:31 am

    Very important breating

  61. Mary M Posted on June 13, 2019 at 7:37 pm

    How r they not blinking for so long

  62. Sarah J.K. Posted on June 15, 2019 at 12:49 am

    A lighter iris color would've made that little demo way more useful because you'd be able to see it well enough on camera before using the flashlight

  63. Apache helicopter Posted on June 16, 2019 at 12:16 am

    Omg.. I have adrenal fatigue but didn't know these two things.. I'm not a smoker and I'm really active (albeit overweight), always been unable to hold my breath.. Then let's talk about my eyes, I'm photosensitive to the point I cry no matter the sun level if I have my eyes unprotected.. Did the test and lordy.. My pupil would just shoot in and out..

  64. zjunegirl Posted on June 18, 2019 at 7:22 pm

    13 seconds it all for me 😆😆

  65. 7Suave Posted on June 20, 2019 at 2:55 am

    Very nice eyebrow

  66. Earthbound One Posted on June 21, 2019 at 5:23 pm

    My pupils are different sizes, but they react to light properly. I've had this issue for years. Sometimes it worries me but my optometrist and doctors don't seem bothered by it at all. I cant help but think I have a neurological problem but my doctor refuses to let me see a neurologist. Every time I visit her it's a complete waste of time, she disregards all my concerns as anxiety and has never done any testing aside from blood tests. There is no way anxiety is causing my pupils to be different sizes than each other.

  67. Mashed Illustration Posted on June 22, 2019 at 10:30 pm

    My iris do that ever since I was a wee lad and I’ve been fatigued for years, guess I should check my adrenal

  68. immortal9922 Posted on June 24, 2019 at 10:12 pm

    Finally a brown eye
    It's always either black or white

  69. Dr. Anna Koltai Posted on June 27, 2019 at 3:10 pm

    When it comes to holding one's breath, what about the size & development of the lungs & cardiovascular fitness? Hellooooo! The adrenal glands have nothing to do with this function.

  70. Spencer Steele Posted on June 28, 2019 at 3:56 pm

    Adrenal fatigue is just a symptom of something else going on in your body UNLESS you have addison or cushings.

  71. Kelly Swenson Posted on July 2, 2019 at 9:32 am

    Can I say, thank you so much for these videos!

  72. Tracey Mallard Fashion and Wigs Channel! Posted on July 2, 2019 at 8:43 pm

    I don’t remember ever being able to hold my breath for long periods of time.

  73. Happy Blue Posted on July 7, 2019 at 1:16 am

    EMF and DEW (directed energy weapons) also impact the adrenals by affecting pregnenolone and DHEA. No one is talking about the effects of Wi-Fi and the cell tower emissions. More people are sick because of this stuff than because of diet.

    If you have Wi-Fi in your house, make sure you have the type of modem where you can turn off Wi-Fi when you're not using it. Don't leave it on all the time.

  74. Jay Tee Posted on July 7, 2019 at 9:11 am

    Wow, I held my breath for 1:07. Wasn't expecting that, since I'm 60 and don't exercise much. In fact, my legs usually ache climbing a flight of stairs, and he has said in another video that it's a sign of adrenal fatigue.
    Haven't tried the iris test yet.

  75. Milos Posted on July 7, 2019 at 12:50 pm

    Asking same question again 😃
    Is soda water or mineral water bad for adrenal glance or kidneys?

  76. Tim L Posted on July 9, 2019 at 1:43 pm

    How does this relate with being out of shape/not exercising regularly? You can get winded going up stairs for those reasons too…

  77. Ms. Keysha Wineglass Posted on July 11, 2019 at 8:00 pm

    OMG! I just did these tests and my adrenals are shot just as I thought! I told my endo my adrenal glands were acting up and he didn't want to test me for any dysfunction. Wait until I see him again! 😤

  78. Matt Klinger Posted on July 11, 2019 at 8:45 pm

    Held my breath for a minute and a half. Guess I'm good?

  79. Laura Davenport Posted on July 13, 2019 at 12:25 am

    Don’t you mean the pupil instead of the iris? The iris is the colored part of the eye

  80. Patricia P Posted on July 13, 2019 at 7:55 pm

    I'm spot on with this…scary!

  81. Angie Gracie Posted on July 13, 2019 at 11:28 pm

    Nice little test. My pupil pulsates like a heartbeat. Why hasn’t my dr ever done this test on me???!!! SMH

  82. Lori Posted on July 14, 2019 at 2:36 pm

    Serious question please answer. Can lithotripsy for kidney stones damage the adrenal and cause symptoms? I really think that’s what happened to me.

  83. John M Posted on July 15, 2019 at 3:41 pm

    Tip: don't do lsd (or atropine eye drops for that matter) prior conducting this test.

  84. Troy D Arsewhooper Posted on July 16, 2019 at 5:06 am

    How do I find a doctor who actually believes adrenal fatigue is real because I've had symptoms for a while and this really just further confirmed it. I had a prescription for propranolol that helped for a bit, but convincing the doctor something is wrong is quite difficult.

  85. Dakoder II Posted on July 17, 2019 at 12:03 am

    So the police can give you a DUI for adrenal fatigue. That's comforting to know that

  86. Veni Vidi Amavi Posted on July 17, 2019 at 7:13 am

    wow that first test, I did not know the lungs were connected to the adrenals in that way! cool and helpful video, thank you sir!!

  87. Mike Hundt Posted on July 18, 2019 at 4:22 am

    Dr Berg , my provider says I should have Power ade zero sugar , it has Sucrose , can you say something to this , because I drink this alot during the day. And I bought your Keto book ,&interminent fasting , but I think I'm slipping with this keto plan.. Mike Thankyou

  88. Austin B Posted on July 21, 2019 at 8:16 am

    The channel should be called dr mansplain

  89. Tex Herrell Posted on July 22, 2019 at 4:13 am

    If you do the light in the eye thing, make sure you don't use a LED. Please. The damage they cause the eyes can not be repaired and it is cummulative. Same as radiation from all the waves we are all being attacked with. Nope. They weren't kidding about the 90% reduction folks. Not even a little bit.

  90. John Grygus Posted on July 28, 2019 at 10:50 am

    Just made 1 minute holding my breath . Yeah!

  91. nicolii100 Posted on July 29, 2019 at 12:01 pm

    Well just watching this video I already know I've got adrenal fatigue.

  92. Taluta Posted on August 3, 2019 at 6:19 pm

    I cannot hold my breath for two seconds …

  93. Carmela Camba Posted on August 13, 2019 at 2:04 am

    I could hold my breath for a minute, guess i'm good?

    I hope Dr.Berg and Dr.Fung establish some clinics abroad.

  94. Deana C Posted on August 26, 2019 at 12:13 am

    Anyone ever tried dr bergs adrenal fatigue support? Or any of his products?

  95. Lena Haris Posted on September 24, 2019 at 2:23 am

    Im so happy i watched this video. Just barely made it to a minute. Its hard to test my eye i will redo. Thank you

  96. Madison Daily Posted on September 26, 2019 at 9:13 pm

    I can't even sit still for 3 minutes let alone hold my breath for that long.

  97. Jasmine Hannig Posted on October 8, 2019 at 8:39 pm

    I just did the eye test and it did exactly what he said (big small, big small non-stop) yikes

  98. C Posted on October 14, 2019 at 3:39 am

    i was on a swim team as a kid so I can hold my breath for a long time
