[[File:Goose_bumps.jpg|Goose bumps|thumb]] '''Cold chill''', often referred to simply as a '''chill''', is a sensation of coldness accompanied by shivering or trembling. It can occur in the absence of actual cold temperatures, often as a response to illness or fever. Chills are a common symptom of the body's reaction to various conditions, including infections such as the [[flu]] or [[pneumonia]], and can also be triggered by emotional reactions.

==Causes==
Chills are primarily caused by rapid muscle contraction and relaxation, known as shivering, which generates heat when the body is cold. However, chills without fever can be caused by a number of factors:
* [[Infection]]: The body's response to infection can cause an increase in body temperature and a feeling of coldness as the body tries to manage its temperature regulation.
* [[Exposure to cold]]: Actual exposure to cold environments can lead to chills as the body attempts to preserve heat.
* [[Psychological factors]]: Emotional stress or anxiety can trigger physical responses in the body, including chills.
* [[Hypoglycemia]]: Low blood sugar can trigger a cold sweat and chills among other symptoms.
* [[Hypothyroidism]]: An underactive thyroid can lead to feeling cold and experiencing chills.

==Symptoms==
Chills are often accompanied by other symptoms depending on the underlying cause. When related to an infection, chills may precede or accompany a fever. Other symptoms might include:
* [[Fever]]
* [[Sweating]]
* [[Headache]]
* [[Muscle aches]]
* [[Fatigue]]

==Treatment==
Treatment for chills depends on the underlying cause. If chills are due to exposure to cold, moving to a warmer environment and wearing warm clothing can help. When caused by an infection, treating the infection itself is necessary, which may involve the use of [[antibiotics]] or other medications. In cases where chills are a symptom of another condition, such as hypothyroidism, managing that condition will help alleviate the chills.

==Prevention==
Preventing chills involves addressing the underlying causes:
* Avoiding prolonged exposure to cold temperatures and dressing warmly can prevent chills caused by the cold.
* Regular hand washing and maintaining a healthy immune system can help prevent infections that may cause chills.
* Managing stress and anxiety can reduce the occurrence of chills related to psychological factors.
