Shivering is a natural bodily response to cold temperature, but when it persists, it can be a sign of an underlying health condition.

Shivering is the body’s way of generating heat by contracting muscles rapidly, which elevates the metabolism rate and produces heat. However, when shivering occurs frequently and for extended periods, it can be an indication of a more profound issue.

This article outlines seven possible health causes of shivering that you should be aware of.

1. Hypothyroidism

The thyroid gland produces hormones that help regulate metabolism and body heat. Hypothyroidism is a condition in which the thyroid gland doesn’t produce enough hormones, which results in a decrease in metabolism and body temperature.

One result of this is feeling cold and shivering all the time. Weight gain, fatigue, and hair loss can also occur as a result of hypothyroidism.

2. Anemia

Anemia is a condition in which there are not enough red blood cells in the body to carry oxygen. When the body can’t get enough oxygen, it can’t produce enough heat, which leads to shivering.

Anemia can be caused by a variety of factors, including a deficiency in iron, vitamin B12, or folic acid.

3. Parkinson’s disease

Parkinson’s disease is a neurological disorder that affects the central nervous system. One of the symptoms of Parkinson’s disease is tremors or shaking. This shaking can occur at rest or during movement, and it can make the body feel cold.

Shivering is one of the symptoms of Parkinson’s disease, which can affect the quality of life of people living with the disease.

4. Raynaud’s disease

Raynaud’s disease is a condition in which the blood vessels in the fingers and toes narrow, leading to reduced blood flow. This narrowing can cause the area to turn white or blue and feel cold to the touch.

Shivering can be a result of reduced blood flow and low body temperature. Although the cause of Raynaud’s disease is unknown, it is thought to be related to the body’s response to cold temperatures or stress.

5. Anxiety

Although anxiety is not a direct cause of shivering, it can cause stress that results in shivering. Anxiety can cause the body to release stress hormones that affect the body’s temperature regulation system.

Anxiety can also increase the body’s metabolism, which can result in shivering. In some cases, anxiety can cause panic attacks, which can lead to shivering.

6. Infection

Infection can cause shivering, as the body’s immune system tries to fight off viruses and bacteria. The shivering may be accompanied by a fever, which is another sign of an infection.

The shivering may come and go, or it may persist, depending on the severity of the infection.

7. Dehydration

Dehydration occurs when you lose more fluid than you take in, leading to a decrease in blood volume. When the body is dehydrated, it may try to conserve heat by shivering. Other symptoms of dehydration include thirst, dry mouth, and dark urine.

In extreme cases, dehydration can lead to confusion, dizziness, and even fainting.

Conclusion

Shivering can be a sign of underlying health issues, and it’s essential to pay attention to its onset and frequency.

If you experience shivering frequently or if the shivering is accompanied by other symptoms, it’s essential to speak with a healthcare provider for diagnosis and treatment. Taking steps to address the underlying condition can help minimize the shivering and restore overall health.
