I have no data on this.

So many people put their laptop right on their stomach while using it.

When I measure the energy coming off of my laptop, the different types of electrical energy, it’s somewhat high. I almost always put it on a pillow before putting it on my stomach. I know many devices are FCC approved, but I don’t know if the FCC takes hours of use on a stomach into account.

Have researchers ruled out this as a possible cause of the increased rate of colorectal cancers?

(Also is the flouride in my water making me see conspiracies that don’t really exist?)

I’ve just been wondering about this recently and there are so many smart people on lemmy I figured someone here would have a smart opinion on this. I know the prevailing theory is colorectal cancers are possibly due to more ultra-processed foods, but has anyone thought about laptops? Is this illogical as a possible cause? It may be that the energy levels aren’t high enough to be a cause or that the colon is too far away from a laptop on a stomach to impact anything.

    Ah, there’s the key part that keeps confusing people: “Energy” when they are thinking of “Power.”

    Energy is a property of a thing. Power is the amount of energy (property of thing) transported over time.

    It’s impossible to list all the energies you interact with from a laptop, but here’s a few:

    1. Various photons from the screen. A photon’s energy is based on its wavelength. A higher energy photon has shorter wavelengths.
    2. The mass of the keyboard is an energy equivalent. A property of the laptop.
    3. The photons transmitted by Wifi, Bluetooth, or other radio sources - these are actually all a lower energy than the ones from a screen.

    Power just means more of those flowing. An infinite number of Wifi photons can hit Carbon, Hydrogen, and Oxygen (most commonly in DNA) and they will never knock an electron off. Same with the photos from your screen. That doesn’t mean there will be no effect.

    Wi-Fi photons in the 2.4Ghz range do transfer energy into water molecules and increase their total kinetic energy (since they can’t “gain mass” this means velocity). Increased Kinect energy really means increased heat. Enough heat, leads to burns.
