A concussion is a mild traumatic brain injury resulting from a jolt or blow to the head, or a hit to the body that causes the head to move rapidly. This sudden movement can cause the brain to move inside the skull, potentially stretching or damaging brain cells and chemical changes. This article clarifies whether feeling cold is a typical sign of a concussion and provides general information about these common head injuries.
Recognizing Common Concussion Indicators
Concussions can manifest through a variety of symptoms affecting different aspects of a person’s well-being. Physical indicators often include headaches, dizziness, nausea, and sensitivity to light or sound. Some individuals may also experience balance problems or blurred vision following a head injury.
Cognitive changes include difficulty concentrating, memory problems, or feeling mentally foggy. Individuals may struggle with processing information or appear confused in their thoughts or speech.
Emotional shifts can include irritability, sadness, anxiety, or increased emotional sensitivity. Sleep disturbances may involve sleeping more or less than usual, or difficulty falling asleep.
The Link Between Concussions and Feeling Cold
Feeling cold is not a common symptom of a concussion. However, a head injury can sometimes lead to physiological responses that cause an individual to feel cold. This sensation often stems from temporary dysregulation within the body’s autonomic nervous system.
The autonomic nervous system controls involuntary bodily functions, including temperature regulation, heart rate, and blood pressure. A concussion can disrupt the hypothalamus, a brain region that acts as the body’s thermostat. This disruption can temporarily impair the body’s ability to maintain a stable core temperature, leading to sensations of coldness or chills.
The body’s general response to trauma can also include a state of physiological shock. This can involve the sympathetic nervous system activating, leading to peripheral vasoconstriction, where blood vessels near the skin surface narrow. This reduces blood flow to the extremities, contributing to a feeling of coldness or clamminess.
Feeling cold could also indicate other serious injuries alongside head trauma. Conditions like internal bleeding, spinal injury, or hypothermia can cause cold sensations and warrant immediate medical attention. Environmental factors, such as a cold environment, can also exacerbate feelings of coldness. While not a direct concussion symptom, experiencing coldness after a head injury should prompt further evaluation.
When to Consult a Medical Professional
Seeking medical attention is important after any suspected concussion, as symptoms vary widely. A professional diagnosis ensures appropriate management and helps prevent potential complications. Even with mild symptoms, a medical evaluation provides clarity and guidance on recovery.
Certain “red flag” symptoms following a head injury require immediate medical care. These include:
- Loss of consciousness
- A worsening headache
- Repeated vomiting
- Increasing confusion
- Seizures
- Weakness or numbness in any part of the body
- Difficulty waking up
