Activates the parasympathetic nervous system. Sucking on an ice cube will get rid of dry mouth and increase saliva production. “Sucking on an ice cube is therefore activating the parasympathetic nervous system to kick in, which can have a calming or distracting effect,” she says.
Since your vagus nerve is the main nerve that is in charge of relaxing your body after it's under stress, icing it may help with anxiety. According to research from 2008 , cold exposure causes a shift in your parasympathetic nervous system, which is controlled by your vagus nerve.
Causes of Pagophagia
Chewing on ice helps people with iron deficiency feel more alert and mentally sharp. Calcium deficiency. Having low levels of iron is the most common nutritional deficiency associated with pagophagia, but low calcium can also trigger the condition.
But, if you want to save yourself the discomfort, just put an ice pack on the center of your chest. Wrap it in a towel, put it right there, lie down for at least 15 minutes, and it is [chef's kiss] a game changer."
Although it's wise to be suspicious of social media health trends, vagus nerve icing is actually part of a real anti-anxiety technique that psychologists and therapists have used for some time now. Dunking your head in ice water could be an effective way to lower your heart rate and redirect blood flow.
“Cold exposure, like icing your chest, face or taking cold showers, will activate the cholinergic neurons of the vagal pathway, releasing the neurotransmitter acetylcholine which tells young lungs to breathe, and your body to chill out.”
Does Chewing Ice Hydrate You? Chewing ice -- and swallowing it -- will give you the same hydration benefits as water. But since ice cubes don't contain very much water, you're unlikely to eat enough ice in a day to stay hydrated.
Chewing Gum and Stress. People chew gum for a variety of reasons, including modulation of psychologic states, for example, to facilitate concentration, relieve stress, and reduce sleepiness. Many studies have examined the effects of gum chewing on stress.
Consuming a lot of ice can damage tooth enamel and cause cracks or chips in the teeth. This can lead to further problems, such as increased sensitivity to temperature and oral pain.
Oral fixations manifest themselves through eating, talking, smoking, alcoholism, thumb-sucking, and nail-biting. The constant chewing of gum, candy, ice, and toothpicks become habits.
Pagophagia (compulsive ice chewing) is a particular form of pica that is characterized by ingestion of ice, freezer frost, or iced drinks. It is usually associated with iron deficiency anemia or mental abnormalities like intellectual disabilities, autism, etc.
Other symptoms suggestive of vagus nerve degeneration. increase stress – Emotional stress: Anxiety, Depression and Panic Attacks: A neurologic and psychiatric like condition caused by cervical spine instability.
Exposure to cold .
Exposing your body to acute cold conditions , such as taking a cold shower or splashing cold water on your face, increases stimulation of the vagus nerve. While your body adjusts to the cold, sympathetic activity declines, while parasympathetic activity increases.
Hormones. We know cold water immersion increases production of mood-elevating hormones and neurotransmitters (beta-endorphins, noradrenaline and dopamine) that can improve symptoms of depression and anxiety by changing the chemistry in our body and brain.
Ice is made up of water, so it's hydrating, which is a plus. However, ice chewing cravings can point to issues such as iron-deficiency anemia or stress.

Three ice cubes equal about one-fourth cup of water.
Your exhale should be long and slow. This is key to stimulating the vagus nerve and reaching a state of relaxation. The vagus nerve is connected to your vocal cords and the muscles at the back of your throat. Singing, humming, chanting and gargling can activate these muscles and stimulate your vagus nerve.
This particular technique involves tapping different parts of the chest to stimulate the vagus nerve and balance our autonomic nervous system. There are a few YouTube videos that demonstrate how to perform vagus nerve tapping, but there is very little information regarding the science or evidence behind the technique.
“You can do things like yoga and deep breathing exercises. Those indirectly stimulate the vagus nerve by stimulating other organs the vagus nerve innervates,” says Howell. “Another interesting one is loud gargling with water or singing, both of which stimulate the vocal cords, which then stimulate the vagus nerve.
