Myth: Alcohol warms you up

For example, if you ask a study participant ‘Does alcohol warm you up?’ the answer may very well be yes. But that’s not what’s really happening in your body. Alcohol causes your blood vessels to dilate, moving warm blood closer to the skin and making you feel warm. But in reality this causes you to actually lose body heat faster.” —Matthew Amsden, expert in research protocol and analysis and CEO of ProofPilot.

Humans and the world we live in are complex, so it’s very unlikely that one particular behavior causes cancer. It’s likely a complex combination of genetics, environment, and behaviors. In addition, follow-up studies haven’t been able to corroborate a link.” —Amsden. Read about some more things that you think cause cancer but don’t.
