'Brain Freeze' Linked to Migraines and Genetics

Research suggests that 'brain freeze,' or ice cream headache, is not just temporary discomfort but is linked to migraines and genetic factors, prompting closer attention to one's headache history.

Scientific Explanation of 'Brain Freeze'

'Brain freeze' is scientifically referred to as a 'cold stimulus headache.' It occurs when extremely cold food or drinks rapidly cool the roof of the mouth or the back of the throat. This sudden temperature change causes blood vessels to quickly narrow and then expand again to restore normal blood flow. Experts explain that pain-sensitive fibers around these blood vessels connect to the trigeminal nerve, which carries pain signals from the face and forehead, resulting in discomfort felt in the forehead or head rather than inside the mouth.

Prevention and Health Connections

Preventing 'brain freeze' is relatively simple. Doctors advise people to slow down when consuming very cold foods and beverages, allowing the roof of the mouth time to warm up naturally between bites or sips. If a headache has already started, warming the roof of the mouth—such as by pressing the underside of the tongue against the palate—or switching to a warm drink can help ease the pain more quickly. Researchers have also found a strong link between 'brain freeze' and migraines, with one study indicating that 93% of migraine sufferers had experienced ice cream headaches, compared to only about one-third of people who did not suffer from migraines. This suggests a potential genetic link to a person's susceptibility to migraines.
