Causes
Medical Advisory
Talk to your doctor about all new, changing, persistent, and returning symptoms as some medical conditions and medications can cause anxiety-like symptoms.
Anxiety Cold Flashes are common anxiety symptoms. Some common causes include:
1. Anxiety-Activated Stress Response
Anxious behavior, such as worry, activates the stress response, often referred to as the fight or flight response. The stress response causes many body-wide changes that prepare the body for immediate emergency action – to fight or flee.[1][2]
Visit our “Stress Response” article for more information about the many physical, psychological, and emotional changes it causes.
Many of the stress response changes can cause a sudden cold flash sensation. For example, the stress response:
Shunts blood away from the skin to parts of the body more vital for survival.
To prepare the body for emergency action, the stress response shunts blood to parts of the body vital to survival, such as the brain, arms, legs, and vital organs, and away from parts less vital for survival, such as the stomach, digestive system, and skin. It accomplishes this by constricting blood vessels in certain parts of the body and dilating them in others.
This shunting action, especially away from the skin, can cause a “cold flash.”
When blood is moved away from the skin, we can feel cold because areas with less blood feel cold. Blood is what keeps the body warm, which is why humans are often referred to as being “warm-blooded.”
The body, being intricately and well designed, is not without resources to deal with this change.
For example, when blood flow is reduced to the skin, the body produces "goose bumps" to raise the hairs on the skin. Raised hairs on the skin provide a form of insulation by creating a thin layer of static air that keeps colder air at a distance.
Consequently, this action compensates heat loss by keeping the skin warm while blood flow is reduced.
Consequently, we can have a “cold flash” and “goosebumps” when anxious.
Tightens the body’s muscles.
The stress response also tightens muscles, making the body more resilient to damage.
Tight muscles can restrict blood flow, including to the skin, causing a cold flash.
Changes internal body temperature.
As mentioned, stress responses constrict blood vessels. Constricted blood vessels reduce blood flow to the skin, where blood is cooled. Less blood to the skin can raise the body’s internal temperature.[3][4]
A rise in body temperature can make a person have a cold flash despite increasing body temperature.
Increases heart rate, respiration, and perspiration.
Increasing perspiration can cool the body, making a person feel cold while a stress response is active.
Increases sensory perception
Increased sensory perception can increase a person’s awareness of bodily sensations, including those associated with shunting blood, tight muscles, and increased perspiration.
Stress hormones affect other hormones.
The stress response secretes stress hormones into the bloodstream, which bring about the stress response’s many actions. Stress hormones can affect other hormone levels. Fluctuating hormone levels can cause sudden cold flashes.
Any combination of the above can cause sudden cold flashes while the stress response and its changes are active.
Many anxious people have cold flashes due to an active stress response.
2. Hyperstimulation
Frequently activating the stress response, such as from overly anxious behavior, can leave the body in a state of semi-stress-response-readiness, which we call “stress-response hyperstimulation” since stress hormones are powerful stimulants.
Hyperstimulation is also often referred to as “hyperarousal,” “HPA axis dysfunction,” or “nervous system dysregulation.”[5][6][7]
Visit our “Hyperstimulation” article for more information about the many ways hyperstimulation can affect the body and how we feel.
Hyperstimulation can cause the changes of an active stress response even though a stress response hasn’t been activated.
Hyperstimulation is a common cause of intermittent cold flashes.
Furthermore, hyperstimulation can cause the nervous system to act erratically,[5][6][7] which can also cause sudden cold flashes.
Sudden cold flashes on or in the body are common for an active stress response or hyperstimulation.
Other Factors
Other factors can create stress and cause anxiety-like symptoms, as well as aggravate existing anxiety symptoms, including:
- Medication
- Recreational drugs
- Stimulants
- Sleep deprivation
- Fatigue
- Hyper and hypoventilation
- Low blood sugar
- Nutritional deficiencies
- Dehydration
- Hormone changes
- Pain

How to get rid of cold flashes anxiety symptoms?
When sudden cold flashes are caused or aggravated by other factors, addressing those factors can reduce and eliminate this common anxiety symptom.
When this symptom is caused by an anxiety-triggered stress response, calming yourself will end the active stress response and its changes. Cold flashes will subside as your body recovers from the active stress response.
Keep in mind that it can take up to 20 minutes or more for the body to recover from a major stress response. But this is normal and shouldn’t be a cause for concern.
When this symptom is caused by hyperstimulation, eliminating hyperstimulation will end this anxiety symptom.
You can reduce and eliminate hyperstimulation by:
- Containing anxious behavior.
- Reducing stress.
- Regular deep relaxation.
- Relaxed diaphragmatic breathing.
- Regular light to moderate exercise.
- Getting regular good sleep.
- Eating a healthy diet of whole and natural foods.
- Avoiding stimulants.
- Passively-accepting your symptoms until they subside.
- Being patient as your body recovers.
Visit our “60 Natural Ways To Reduce Stress” article for more ways to reduce stress.
Recovery Support members can view chapters 5, 6, 7, 14 and more for more detailed information about recovering from hyperstimulation and anxiety disorder.
As the body recovers from hyperstimulation, it stops sending symptoms of hyperstimulation, including sudden cold flashes.
However, eliminating hyperstimulation can take much longer than most people think, causing symptoms to linger longer than expected.
As long as the body is hyperstimulated, even slightly, it can present symptoms of any type, number, intensity, duration, frequency, and at any time, including this one.
Even so, since sudden cold flashes are common symptoms of stress (acute and chronic), including anxiety-caused stress, they are harmless and needn't be a cause for concern. They will subside when unhealthy stress has been eliminated and the body has had sufficient time to recover and stabilize. Therefore, there is no reason to worry about this common anxiety and hyperstimulation-caused symptom.
Since worrying and becoming upset about anxiety symptoms stress the body, these behaviors can interfere with and stall recovery.
Passively accepting your symptoms – allowing them to persist without reacting to, resisting, worrying about, or fighting them – while doing your recovery work will cause their cessation in time.
Acceptance, practice, and patience are key to recovery.
Recovery Support
The Recovery Support area of our website contains thousands of pages of important self-help information to help individuals overcome anxiety disorder, hyperstimulation, and symptoms.
Due to the vast amount of information, including a private Discussion Forum, many of our Recovery Support members consider it their online recovery support group.
Therapy
Unidentified and unaddressed underlying factors cause issues with anxiety. As such, they are the primary reason why anxiety symptoms persist.
Addressing your underlying factors (Level Two recovery) is most important if you want lasting success.
Addressing Level Two recovery can help you:
- Contain anxious behavior.
- Become unafraid of anxiety symptoms and the strong feelings of anxiety.
- End anxiety symptoms.
- Successfully address the underlying factors that so often cause issues with anxiety.
- End what can feel like out-of-control worry.
All our recommended anxiety therapists have had anxiety disorder and overcame it. Their personal experience with anxiety disorder and their Master's Degree and above professional training give them insight other therapists don't have.
If you want to achieve lasting success over anxiety disorder, any one of our recommended therapists would be a good choice.
Working with an experienced anxiety disorder therapist is the most effective way to treat anxiety disorder, especially if you have persistent symptoms and difficulty containing anxious behavior, such as worry.[8][9][10]
In many cases, working with an experienced therapist is the only way to overcome stubborn anxiety.
