Uncontrollable shivering often signals your body's response to cold, fever, or stress. Common triggers include infections raising body temperature or emotional surges like anxiety releasing adrenaline. Seek medical help promptly if it persists with other symptoms like fever or weakness.
Common Causes
Fever from illness causes muscles to contract rapidly to generate heat, leading to rigors or chills. Low blood sugar, dehydration, or extreme exertion can disrupt temperature regulation and provoke shaking. Emotional factors such as fear, anxiety, or psychogenic disorders trigger adrenaline-fueled tremors that may stop with distraction.
When to Worry
Shivering without fever might stem from hypothermia, anemia, thyroid issues, or conditions like sepsis. Post-exercise cooling or medication side effects, including post-anesthesia, are other culprits. Persistent episodes warrant a doctor's evaluation to rule out underlying issues.
Next Steps
Warm up gradually if cold-related, hydrate well, and monitor for fever or confusion. Avoid self-diagnosis; consult a healthcare professional for personalized advice, especially if uncontrollable.
