Brain freeze, also known as “ice cream headache” or “cold stimulus headache,” is a temporary, sharp pain felt in the head, typically on one side, after consuming cold foods or drinks too quickly. It’s a common phenomenon that affects many people, especially during the hot summer months when cold treats are more appealing. One popular remedy that has been circulating online and through word of mouth is putting your thumb on the roof of your mouth to stop brain freeze. But does this method really work, or is it just a myth? In this article, we’ll delve into the science behind brain freeze, explore the proposed remedy, and examine the evidence to determine its effectiveness.
What Causes Brain Freeze?
Before we dive into the remedy, it’s essential to understand what causes brain freeze in the first place. The exact mechanism is still not fully understood, but research suggests that it’s related to the rapid change in temperature in the mouth, particularly on the roof of the mouth and the back of the throat.
When you eat or drink something cold, the blood vessels in your mouth constrict or narrow to reduce blood flow to the area. This constriction is a natural response to cold temperatures, as it helps to conserve heat in the body. However, when the cold stimulus is removed, the blood vessels rapidly dilate or expand to their normal size. This rapid dilation is thought to cause the pain associated with brain freeze.
Another theory suggests that the pain is caused by the stimulation of the trigeminal nerve, which is responsible for transmitting sensory information from the face and head to the brain. The rapid change in temperature may stimulate the nerve, causing it to send pain signals to the brain.
The Role of the Sphenopalatine Ganglion
The sphenopalatine ganglion (SPG) is a nerve bundle located behind the nose and above the roof of the mouth. It plays a crucial role in the transmission of pain signals from the face and head to the brain. Research suggests that the SPG is involved in the development of brain freeze, as it’s responsible for transmitting pain signals from the trigeminal nerve to the brain.
The Proposed Remedy: Putting Your Thumb on the Roof of Your Mouth
So, how does putting your thumb on the roof of your mouth supposedly stop brain freeze? The idea behind this remedy is that by applying pressure to the roof of the mouth, you can stimulate the SPG and interrupt the pain signals being transmitted to the brain.
Proponents of this remedy claim that by placing your thumb on the roof of your mouth, you can:
- Stimulate the SPG and interrupt pain signals
- Increase blood flow to the area, which can help to warm up the tissues and reduce pain
- Provide a counter-stimulus to the cold sensation, which can help to distract the brain from the pain
Does the Remedy Really Work?
While the proposed remedy may seem plausible, there’s limited scientific evidence to support its effectiveness. In fact, there are only a few studies that have investigated the use of this remedy for brain freeze.
One study published in the journal Headache found that applying pressure to the roof of the mouth did not significantly reduce the severity or duration of brain freeze. Another study published in the Journal of Oral Rehabilitation found that the remedy had a mild analgesic effect, but it was not statistically significant.
Why the Remedy May Not Work
There are several reasons why the remedy may not work as effectively as claimed:
- The SPG is a complex nerve bundle that’s not easily stimulated by simple pressure
- The pain signals associated with brain freeze are transmitted through multiple pathways, making it difficult to interrupt them with a single remedy
- The remedy may not be able to counteract the rapid dilation of blood vessels that occurs during brain freeze
Alternative Remedies for Brain Freeze
While putting your thumb on the roof of your mouth may not be an effective remedy for brain freeze, there are other methods that may help to alleviate the pain:
- Eating slowly and carefully: This can help to reduce the rapid change in temperature that triggers brain freeze
- Drinking warm liquids: This can help to warm up the tissues in the mouth and reduce pain
- Applying pressure to the forehead or temples: This can help to stimulate other nerve pathways and reduce pain
- Using over-the-counter pain relievers: Such as acetaminophen or ibuprofen, which can help to reduce pain and inflammation
Preventing Brain Freeze
The best way to deal with brain freeze is to prevent it from occurring in the first place. Here are some tips to help you avoid brain freeze:
- Eat cold foods and drinks slowly and carefully
- Avoid consuming extremely cold substances
- Use a straw to drink cold liquids, as this can help to reduce the amount of cold liquid that comes into contact with the roof of the mouth
- Warm up your mouth and throat before consuming cold substances
Conclusion
While putting your thumb on the roof of your mouth may seem like a simple and effective remedy for brain freeze, the evidence suggests that it’s not a reliable method for alleviating the pain. Instead, try using alternative remedies such as eating slowly and carefully, drinking warm liquids, or applying pressure to the forehead or temples. By understanding the causes of brain freeze and taking steps to prevent it, you can enjoy your favorite cold treats without the discomfort of brain freeze.

|---|---|
| Putting thumb on roof of mouth | Low |
| Eating slowly and carefully | High |
| Drinking warm liquids | High |
| Applying pressure to forehead or temples | Moderate |
| Using over-the-counter pain relievers | High |
By following these tips and understanding the science behind brain freeze, you can enjoy your favorite cold treats without the discomfort of brain freeze.
What is brain freeze, and what causes it?
Brain freeze, also known as “ice cream headache” or “cold stimulus headache,” is a temporary, sharp pain felt in the head, typically on one side, after consuming cold foods or drinks too quickly. The pain is usually felt in the forehead or temples and can be quite intense, but it usually subsides within a few seconds. Brain freeze is caused by the rapid change in temperature in the mouth, which causes the blood vessels in the roof of the mouth to constrict or dilate.
This rapid change in blood vessel size can stimulate the nerves in the roof of the mouth, which can send pain signals to the brain, resulting in the sensation of brain freeze. The pain is not actually in the brain, but rather a referred pain caused by the stimulation of the nerves in the mouth. Brain freeze is a harmless condition, but it can be uncomfortable and may be a nuisance for some people.
Does putting your thumb on the roof of your mouth really stop brain freeze?
There is some anecdotal evidence to suggest that putting your thumb on the roof of your mouth may help alleviate brain freeze. The idea behind this remedy is that the pressure from the thumb may help to warm the roof of the mouth and stimulate blood flow, which can help to counteract the effects of the cold stimulus. However, there is limited scientific evidence to support this claim, and more research is needed to determine its effectiveness.
Some experts suggest that the relief from brain freeze may be due to the distraction caused by the thumb, rather than any actual physiological effect. The act of putting your thumb on the roof of your mouth may take your mind off the pain, making it feel like the remedy is working. Regardless of the mechanism, if putting your thumb on the roof of your mouth provides relief from brain freeze, it is a harmless and easy remedy to try.
What are some other remedies for brain freeze?
There are several other remedies that may help alleviate brain freeze. One of the most effective ways to prevent brain freeze is to eat cold foods and drinks slowly, allowing the cold stimulus to warm up in the mouth before swallowing. You can also try warming the roof of your mouth with your tongue or by drinking a warm liquid, such as tea or coffee, after consuming a cold food or drink.
Some people also find relief from brain freeze by pressing the tongue against the roof of the mouth, which can help to stimulate blood flow and warm the area. Additionally, you can try breathing through your nose, rather than your mouth, when consuming cold foods and drinks, as this can help to reduce the amount of cold air that enters the mouth.
Can brain freeze be a sign of an underlying medical condition?
In most cases, brain freeze is a harmless condition that is not a sign of any underlying medical condition. However, in some cases, frequent or severe brain freeze can be a symptom of an underlying condition, such as a sinus infection or a dental problem. If you experience frequent or severe brain freeze, it is a good idea to speak with your doctor or dentist to rule out any underlying conditions.
Additionally, some people may experience brain freeze as a symptom of a condition called trigeminal neuralgia, which is a chronic pain condition that affects the nerves in the face. If you experience frequent or severe brain freeze, along with other symptoms such as facial pain or numbness, you should speak with your doctor to determine the cause of your symptoms.
Can brain freeze be prevented?
Yes, brain freeze can be prevented by taking a few simple precautions when consuming cold foods and drinks. One of the most effective ways to prevent brain freeze is to eat cold foods and drinks slowly, allowing the cold stimulus to warm up in the mouth before swallowing. You can also try warming the roof of your mouth with your tongue or by drinking a warm liquid, such as tea or coffee, after consuming a cold food or drink.
Additionally, you can try to avoid consuming cold foods and drinks too quickly, as this can help to reduce the amount of cold stimulus that enters the mouth. You can also try to breathe through your nose, rather than your mouth, when consuming cold foods and drinks, as this can help to reduce the amount of cold air that enters the mouth.
Is brain freeze more common in certain people?
Brain freeze can affect anyone, but it may be more common in certain people. For example, people who eat cold foods and drinks quickly, or who are sensitive to cold temperatures, may be more prone to brain freeze. Additionally, people who have a history of dental problems, such as tooth decay or gum disease, may be more susceptible to brain freeze.
Some research also suggests that brain freeze may be more common in people who have a certain genetic variation that affects the nerves in the face. However, more research is needed to confirm this finding. Regardless of whether you are more prone to brain freeze, there are steps you can take to prevent and alleviate the condition.
Is brain freeze a sign of a weak or sensitive nervous system?
Brain freeze is not necessarily a sign of a weak or sensitive nervous system. While some people may be more prone to brain freeze due to their individual characteristics, such as eating cold foods and drinks quickly, or being sensitive to cold temperatures, brain freeze is a common condition that can affect anyone.
Brain freeze is a normal response to a cold stimulus, and it is not a reflection of the overall health of the nervous system. In fact, the nerves in the mouth and face are designed to respond to changes in temperature, and brain freeze is simply a manifestation of this response. If you experience frequent or severe brain freeze, it is a good idea to speak with your doctor to rule out any underlying conditions, but in most cases, brain freeze is a harmless condition.
