What can cause severe chills?
Severe chills, also known as cold shivers, are a common symptom that can be caused by a variety of factors. Understanding the potential causes of these intense shivers can help individuals recognize when they may need medical attention. In this article, we will explore some of the most common causes of severe chills and what they might indicate.
1. Infections and Illnesses
One of the most common causes of severe chills is an infection or illness. The body’s immune system responds to infections by producing a fever, which can trigger chills as the body tries to raise its temperature to fight off the infection. This can be seen in various infections, including:

In some cases, severe chills may be a sign of a more serious infection, such as sepsis, which is a life-threatening condition that requires immediate medical attention.
2. Fever
Fever itself can cause severe chills. When the body’s temperature rises, it can trigger shivering as a way to generate heat and maintain the elevated temperature. Fever can be caused by various factors, including infections, inflammatory diseases, and certain medications.
3. Autoimmune Disorders
Autoimmune disorders, such as lupus or rheumatoid arthritis, can cause the immune system to attack healthy tissues, leading to inflammation and fever. This can result in severe chills as the body tries to combat the inflammation and maintain a higher temperature.
4. Hypoglycemia
Hypoglycemia, or low blood sugar, can cause severe chills, along with other symptoms such as dizziness, confusion, and sweating. This occurs when the body’s cells are not receiving enough glucose to function properly, leading to a cascade of physiological responses that can trigger chills.
5. Medications and Toxins
Certain medications and toxins can also cause severe chills. For example, certain antibiotics, chemotherapy drugs, and illegal drugs such as cocaine can trigger chills as a side effect.
6. Environmental Factors
Exposure to extreme cold temperatures can cause the body to shiver as a means of generating heat. While this is a normal response, prolonged exposure to cold can lead to severe chills and potentially hypothermia.
In conclusion, severe chills can be caused by a variety of factors, ranging from infections and illnesses to environmental conditions. Recognizing the potential causes of these intense shivers can help individuals seek appropriate medical attention when necessary. If severe chills are accompanied by other concerning symptoms, such as a high fever, difficulty breathing, or confusion, it is important to seek immediate medical care.
