Understanding Brain Freeze and Its Effects

The video explores the phenomenon of brain freeze, also known as ice cream headaches. It discusses scientific research on the topic, explaining how rapid constriction and expansion of blood vessels in the mouth can trigger pain via the trigeminal nerve. Alternative theories suggest the brain increases blood flow to maintain temperature. The video also offers tips to prevent and alleviate brain freeze, such as pressing the tongue to the roof of the mouth or consuming cold items slowly.
