why shivering without fever

Shivering, also known as involuntary muscle contractions or tremors, is the body's way of generating heat to maintain a stable core temperature. Shivering typically occurs when the body is exposed to cold temperatures, but it can also happen in response to other stimuli, such as fear, anxiety, or excitement.

While shivering is commonly associated with fever, it can also occur without an elevated body temperature. Some common causes of shivering without fever include:

Cold exposure: The most common cause of shivering without fever is exposure to cold temperatures. When the body senses a drop in temperature, it triggers shivering to generate heat and warm the body.

Anxiety and stress: Anxiety and stress can cause the body to release adrenaline and other stress hormones, which can cause muscle tension and shivering.

Hypoglycemia: Low blood sugar levels can cause shivering, as the body attempts to generate heat to compensate for the lack of energy.

Dehydration: Dehydration can cause shivering, as the body attempts to generate heat and maintain its core temperature.

Medications: Some medications, such as antidepressants and antipsychotics, can cause shivering as a side effect.

In summary, shivering can occur without fever due to a variety of reasons, including cold exposure, anxiety and stress, low blood sugar levels, dehydration, and medications. If you are experiencing shivering without an obvious cause, it is recommended to consult with a medical professional to determine the underlying cause and receive appropriate treatment.
