Do infrared thermometers damage the pineal gland? Experts respond!


All the publications unearthed by AFP begin in the same way: they claim to warn about the dangers of infrared thermometers by reporting “the testimony of an Australian nurse”, “very telling”.

According to these “testimonies”, taking a temperature using an infrared thermometer endangers the pineal gland, located in the brain. These posts have been shared nearly 6,000 times on Facebook since the end of June.

This is false: the National Agency for the Safety of Medicines and Health Products (ANSM) details to AFP on July 23 that “the individual tested is in no way subjected to exposure to infrared radiation during the temperature measurement ”.

The thermometer actually captures infrared spectra emitted by the human body through a lens on a sensor. Depending on the wavelengths of the radiation received, it displays a higher or lower temperature.

Located too deep in the brain

Moreover, even if infrared rays were directed towards this gland, it is located too deep in the brain for them to reach it, according to Gabrielle Girardeau, researcher in neuroscience at the National Institute of Health and Medical Research. (Inserm) joined by AFP on July 22. “Light has a very low capacity to penetrate the barrier formed by the skull, even if infrared wavelengths penetrate more easily”, she explains.

“We would have to cross the cranium completely to reach this small gland which is located at the bottom of the brain”, abounds Mireille Rossel, teacher-researcher in neuroscience at the Ecole Pratique des Hautes Études (EPHE), in a telephone exchange with AFP July 23.

The pineal gland, or epiphysis, is a small gland of about 8 millimeters “which secretes melatonin, a hormone involved in circadian rhythms, that is to say the alternation of phases of sleep and wakefulness [jour-nuit]
», Explains Gabrielle Girardeau.

Maude Beaudoin-Gobert, doctor in neurosciences affiliated with the university Claude Benard Lyon 1, specifies to AFP on July 23 that these are the “cells of the retina [qui] detect light and transmit the information to a number of relays in the brain before reaching the pineal gland ”. This activates the secretion of melatonin during the night.

“I think the genesis of this belief in the effect of the thermometer on the pineal gland comes from the fact that in reptiles and birds this gland is indeed just under the skull and contains photosensitive cells (and therefore sensitive to sunlight. visible and infrared spectrum) ”, the researcher reckons. This is not the case for mammals.

Some of these infrared thermometers however use a laser pointer, a small light which is not composed of infrared radiation and which “serves to direct the thermometer towards the part of the body whose temperature one wishes to measure”, adds the ANSM. But its power “is low and warnings are present indicating not to look at the beam”.

The agency also specifies that it “has not received any report on problems related to the use of this type of thermometer” and that “there is no basis on the risks associated with their use”.

  1. Global elite fake news. You are a bunch of fucking liars saying it won’t affect the pineal gland. Do research people. Nurses have said using the wrist gives a good read. Folks please don’t accept everything you read as truth. Why would anyone want an infrared beam of radiation aiming right at your head (like a gun) to desensitize you? Always ask questions and research further before any government “authority” says they’re doing “what’s best for you.”

  2. Concordo plenamente, se tenho a opção de fazer a leitura no pulso porque fazê-lo direto em minha testa podendo até atingir minha visão, é pulso ou nada e deu.

    1. The IR thermometer is NOT sending infra red radiation , It is just receiving the radiation from the body and measuring it . Understand the difference !
      Someone was referring to spiritual mumbo jumbo of the pineal gland ! OMG !

  3. EXPERTS OVERLOOKED
    ARE WE TALKING ABOUT A HAND HELD MACHINE OR THE ANATOMY. LETS LOOK AT ETYMOLOGICAL MEANING OF THE WORD ANATOMY (AN MEANS SUN SOLOR ) AND ATOMS ARE STARS AND SUNS YES WE ARE WALKING AROUND WITH TINY STARS AND SUNS IN OUR BODIES THAT ARE ENCODED MATTER. AN ATOM EMITS ENERGY AND RECEIVES ENERGY AND IS HIGHLY SENSITIVE TO ANY FORM OF LIGHT. WE ARE BATHING IN AN OCEAN OF LIGHT. IT DOESN’T MATTER THE DISTANCE.VIBRATION AND TONE HAVE AN ENERGY SIGNATURE. SO GABRIELLE GIRARDEAU STOP PLAYING US LIKE WERE STUPID WE ARE A GOD BODY. LOOK AT ETYMOLOGY OF MEDICINE MEDI MEANS MEDIUM AND CINE MEANS TO KILL. BODY CAN CAPTURE LIGHT DOWN TO ITS CORE ATOMIC LEVEL. SO YES THAT INFRARED LIGHT CAN PENETRATE THE PINEAL GLAND. LIGHT TRAVELS 182 miles per second

  4. Sudinfo with AFP, I am on AO (Acronym OVERLOAD)! Please say what your acronyms stand for. The small extra effort on your part is a stalled eclipse on your reader’s parts leaving us in the dark when I think your original desire was to enlighten? You never did identify who, what or ? AFP is.

  5. N.SANKARANARAYANAN: Are you a specialist in the field of radiation and were you involved in the manufacturing or study of the long-term side effects of the use of these infrared thermometers?

    My child is going back to school and will have to do temp. checks everyday. How will this repeated use impact on my child?

    1. Infrared thermometers don’t emit anything. They are designed to read infrared radiation that our body emits. There is absolutely nothing to worry about when reading temperatures using thermal guns for anyone. Just make sure the laser pointer is not pointing directly towards eyes.

      1. THANK YOU for so patiently trying to make this clear to people who are so blinded by fears about what they don’t understand❣️
