You're listening to Bulletproof Radio with Dave Asprey.

Today's cool fact of the day is that adapting to life in northern climates may have actually

been a real headache.

Researchers just discovered that there's a certain genetic variation in a cold-sensitive

protein that's way more common in people from northern Europe than it is in Asians or

Africans.

That variation is linked to migraine headaches, which you're way more likely to get if you

have northern European ancestors.

For instance, in Finland, 88% of people have that genetic variation and they have a much

higher risk for migraines, but if you're from Nigeria, only 5% of people have that.

We don't think it's a coincidence.

The new study authors just a thousand of years ago, this mutation made people who lived

in cold, dark places better able to handle them.

It's called TRPM8 for people who like to go Google that sort of thing.

What that means is, well, you might be more likely to get a migraine if you're from that

genetic history.

What you can do about migraines, well, that's probably a mitochondrial thing or a blood

flow thing and I'm not going to tell you how to solve that right now, but I can tell

you that eating less stuff that causes inflammation is probably a good start.
