  2. I always believe in moderation. Too much of anything is bad for you, even if we aren't sure there's anything particularily wrong with that thing. Regardless if excessive phone usage causes cancer or not, being on your phone 24/7 doesn't sound particularily healthy either.

  3. Okay now go the next mile and talk about 5G, with even shorter wavelengths. There’s already links to cancer…so many thats cities are blocking this info from getting out. Foodforthought

  4. If radio and microwaves are harmful, then visible light should be much more so as it is at a higher energy level.

  5. Instructions on using a X-Ray unclear, my friend is a rotisserie chicken and i have been charged with murder.

  6. So, MSM just cherry picking and using faulty, inconclusive data to create a headline just to manipulate us as usual. Typical.

  7. I've been fast and loose with my password protocol for 20 years now, and never had any issue with identity theft… maybe I'm lucky, or maybe the simple precautions of limiting my device access, running ad block and no-script on my browsers has been enough. honestly since windows implemented UAC in windows 7 (never had vista) I haven't had a compromised system. Even administrating an intranet for a company, my hardware firewall (sonicwall whatever the version) and limiting some user permissions stopped all garbage coming into my system. I walked into the position and every single computer was compromised with dozens or HUNDREDS of malware instances; after cleaning the boxes out and implementing those simple solutions, I never had a security issue come up.

  8. I would like to know about the methodology of those "safety limits", as in how did they come up with them, and how are they enforced?

    If you are exposed to just one EMF-emitting device, it probably won't hurt you.

    Disclaimer – unscientific scaremongering part below.

    What concerns me is the cumulative effect. Nowadays we are exposed to far more than just a cell phone in a pocket. EVERYBODY is using cellphones. There are many more towers to improve coverage, and networks from multiple companies. Every business uses wifi, and larger businesses/schools use LOTS of it. There are also TV/radio towers, satellites, and of course devices with electric motors (depending on your occupation, exposure to the latter can be heavy).

    It's a real soup. I'd like to see a study compare the effects of living near dozens of cell phones and cell phone/other towers, plus wifi and large electric motors, against living in the middle of nowhere where the only artificial EMF exposure is from satellites and long-range radio.

  9. Second video I've watched from this channel… was going to subscribe until seeing this vid. While it is true that first person reporting of personal experience can be suspect… so too can be entire studies funded and run by supposedly or otherwise reputable institutions–such as universities. This is plainly exemplified by the history of tobacco marketing and use… an issue over which the tobacco industry exercised great will and influence to pervert reporting of the truth of the dangers of tobacco use. No mention of this is made at all in this video while first person accounts are put into question. This reveals a bias which places this video into the realm of PR. Shame to those involved in this video's creation… shame to those working on this channel.

  10. Visible light has higher frequency than Microwaves so do you have eye or brain cancer from not blinking enough? Exactly, also with infrared, do you feel like your mutating when you stand in the sun? No. People are stupid (Not u Kurz ur great)

  11. Absolutely it does. With 5G you're going to see brain cancer skyrocket around the world. I never carry a phone except when absolutely necessary and keep it off as much as possible.

  12. Honestly, modern technology saves lives every day. Even though there are negative effects, nobody can deny that there are positive effects as well.

  13. Am I the only one bothered by the EM radiation being represented by colors that are opposite to the spectrum?
    At 1:03 they show microwave as a pink-ish colour, and get redder as the wavelength decreases. This is completely backwards to how the spectrum operates.
    I get that you can't see most of the spectrum (and there is certainly an artistic design decision here), but some level of scientific accuracy is appreciated.

  14. The placebo effect and nocebo effect are extremely powerful. Even if you know your getting a sugar it will still work against pain. Because its not that you think its a pain pill, but that you trust the person giving you the pill that it will work.

  15. What about wireless headphones? Is it safe to use bluetooth devices in close proximity to your brain for several hours a day?

  16. Out of all the name you can pick for this channel you pick "KURZGESAGT"!! Watching your content is the other things but remembering the name it's a daily task.

  17. 5:10 Knowing how people loves conspiracy theories and freak out about the silliest thing, why even do they say anything?

  18. I have used a computer with only minimal breaks for quite an extended period of time, it has all my hobbies and is my source of work. If I have not gotten anything from my lifestyle yet, I doubt I will be getting anything soon.

  19. but you have to be aware of the thermal effect of high power EM radiation…(RF Hazard)
    your body may get damaged if you stay too close and too long to any antenna which is transmitting RF at high power,(ex: radar, HF antenna…etc) just like microwave oven.

  20. Television/Facebook/Twitter and a lot of MSM thing propagated through these radiowaves are WHAT makes you sick and feel not well. So yes you feel better inconsciously when you close that thing.

    However as an electronician I must bring my advice: with the 4G and 5G reaching higher and higher frequencies, multiplications of antennas, we are clearly headed to a huge health issue. And knowing the business behind this, it's not gonna end well.
    Instead of liberating the VHF/UHF bands for mobile comms – which are harmless, the idea of having a 10GHz antenna at 10Kw and a 10GHz transmitter at the same 10Kw but that will radiate on hundreds of meters instead of kilometres. So, You don't want this, and as a tech loving pone, I must condone the malpractice of this industry and the standards.

  21. Thank you so much for makeing this video because I have been woried every night that my phone is gonna give me a brain tumor. -❤❤

  22. bad information in this video. It is evident that Radio and Smartphone antenna have effect on tumor, cancer and leukemia increasing risk of disease. Can see Radio Vaticano effect (power related to transmission on all world induce +20% leukemia effect on people near Radio Antenna). The problem is do by hight frequency and electromagnetic field power, for this UE limitating elettrosmog with law (but not so restrictive). Smartphone have a single low power. Smartphone antenna serve thousand of smartphone at same time inside an area, for this have extended power to work with all thousand smartphone. Not confund Antenna effect with smartphone effect!

  23. Kurzgesagt, have you seen the studies on the impact 5g has on birds and wildlife ?
    Electro smog may not be harmful for humans, but for wildlife it’s an other story

  24. "Radio waves may not hurt us, but people trying to take advantage of our data certainly will."
    ~Kurgesagt 2019

  25. My phone suddenly became a mini robot with legs and arms and he's all day trying to cut my leg with his fists, we became good friends

  26. I get a headache when i stand next to a microwave that isnt shielded properly… to test your microwave.. put your mobile phone inside, shut the door and then ring it.. if it rings.. your microwave is leaking👌🏻👌🏻

  27. You know I watch your videos all the time I just wish there was more of them but I know how long it takes you to make you to make them
