Can someone tell me whether this is scientifically right or wrong. Someone in an ME facebook group was saying that if she applies cold to her head (like wet hair or an ice pack) for a certain amount of time, her cognition improves. She attributes that to the cold reducing brain inflammation. Is that scientifically plausible?
And if so, would that mean that hot weather would result in increased brain inflammation?
