How did i get brain freeze by just being cold?
You can have a brain freeze by just being in a small environment.
- You are warmed up. Let's say you were running outside in the cold.
- You heat up gradually
- You inhale cold air through you mouth. If u are tiered, most likely you exhale it through your mouth.
- This acts like a cold cream in a hot day. The top of your mouth is HOT but it is subjected in cold air.
- This triggers the the nerve above your mouth signaling the brain that its COLD.
- Blood vessels then get bigger to warm it up and you get the headache.
How to get rid of it in such situation:
- INHALE from MOUTH, but EXHALE from NOSE --- exhalation = to warm air(CO2 and H2O vapor)
- By doing this you eliminate the cold feeling--- you make the circumstances balanced.
