This makes no sense from a thermodynamic standpoint. The flow doesn’t increase due to cold. If anything the blood vessel becomes constricted due to the drop in temperature and the flow of blood staying the same (heart keeps a pumpin) increases the pressure against the vessel wall which then pushes against the surrounding area.
It also explains both the thumb against the roof (someone else noted) which cuts off the flow thus limiting the pressure buildup further up the chain - and the 2nd way I know of which is to place a cold item on your forehead which constricts an adjacent area limiting the impact to the first.
cold increases flow...right

"The brain is one of the relatively important organs in the body, and it needs to be working all the time," study researcher Jorge Serrador, of Harvard Medical School, said in a statement. Did they study liberals to confirm this?

Hot tea works much better for me when I start getting migraine-y.

I accidentally used a photo with a Getty Images copyright, which is verboten on FR. I asked the mod to delete the post which he or she did. Don’t need to cause legal issues for JimRob.

And all this time I thought the pain from brain freeze was the cold stimulating the maxillary branch of the trigeminal nerve, thus causing a neuralgia... hmmm, learned something today

I’ve had some who suffered from migraines say hands in the water helped prevent / ameliorate their migraines.

They were studying cause not effect. And migraines, not sinus headaches.

An old time remedy used to prevent or moderate migraines is putting your hands in warm water to divert the blood flow to your hands.
Hadn't heard that one before...I'll have to try that next time I have a migraine. I have meds that work decently enough minimizing a migraine once it's started.
Back in the Navy, the doc told me to pound down a pot of coffee once one started...that seemed to work...sometimes. Only problem with that was when it didn't work, I would be wide awake through the whole migraine hell. Of course I could never sleep through a migraine anyway.

“sinus headache and brain freeze have the same effect on a person?”
Hadn't thought of this but I have had brain freeze and sinus headaches for years. I can control brain freeze by not instigating it with extreme cold but the sinus headache rolls on it's own and I can't predict it.
I do know that caffeine helps with sinus headaches.
So does throwing up (maybe that takes the pressure off of the thing they mentioned). And, yes, I have hurt enough to provoke vomiting.
Caffeine (with pressure on system) works, too.

“It is not news that increased blood flow to the brain causes migraines. An old time remedy used to prevent or moderate migraines is putting your hands in warm water to divert the blood flow to your hands.”
Had never heard of this; good to know it now so I don't have to vomit to take the pressure off.
Thanks!

Although the study may sound silly to you, it has indeed contributed to our knowledge base about how the brain works.
Having been a life long sufferer of migraines, I appreciate any advance towards finding their cause and a treatment to prevent them. While it’s been long known that migraines are caused by vascular activity, it’s still not known what causes that. Only time and more studies are going to figure it out.
And, BTW, as is often the case, research into one subject can lead to insights into something completely outside the scope of the study. This may be one of those examples.
