ICE-CREAM HEADACHES
- Ice cream headaches are brief, stabbing headaches that can happen when you eat, drink or inhale something cold.
- Biting into an ice cream cone is a common trigger, but eating or drinking other frosty items, such as ice pops and slushy frozen drinks, can have the same “brain-freeze” effect.
- Officially known as cold stimulus headaches, they can also occur when you suddenly expose your unprotected head to cold temperatures, such as by diving into cold water.
- No one is quite sure what causes the actual pain, but it is thought that a combination of direct stimulation of temperature-sensitive nerves plus the cold’s effects on blood vessels running along the roof of the mouth.
- The good news: Most ice cream headaches are gone as quickly as they develop.
Symptoms
Symptoms of an ice cream headache include:
- Sharp, stabbing pain in the forehead
- Pain that peaks about 20 to 60 seconds after it begins and goes away in about the same time
- Pain that rarely lasts longer than five minutes
Causes
- It’s not just ice cream; any cold stimulus can cause the nerve pain that results in the sensation of a brain freeze.
- Brain freeze is caused by:
- Cooling of the capillaries of the sinuses by a cold stimulus, which results in vasoconstriction (a narrowing of the blood vessels).
- A quick rewarming by a warm stimulus such as the air, which results in vasodilation (a widening of the blood vessels).
- These rapid changes near the sensitive nerves in the palate create the sensation of brain freeze.
- The proximity of very sensitive nerves and the extreme stimuli changes are what cause the nerves to react.
Cure
- The sensation is not serious but can be very unpleasant. Brain freeze treatments include:
- drinking some warm water
- pushing the tongue to the roof of the mouth, which helps warm the area
- covering the mouth and nose with the hands and breathing rapidly to increase the flow of warm air to the palate
- A preventative cure is reducing the cold stimuli on the palate, which means avoiding large amounts of cold food or drink at once.
Risk factors
- Ice cream headaches can affect anyone.
- You might be more susceptible to ice cream headaches or have more-severe ice cream headaches if you’re prone to migraines.
Prevention
- The best way to avoid getting ice cream headaches is to avoid the cold food or drinks or exposure to cold that causes them.
