What if I have the Chills but no Fever? – 5 Reasons for the Condition

Having “the chills” describes the sensation of feeling cold. You feel it racking through your body, touching your bones with the cold. Have you ever experienced that feeling? Most of us know chills from developing a fever; as the pyrogen levels build in the body and reset the body’s temperature set point, it takes us time to catch up to that new setting, resulting in the onset of chills. However, we can experience chills without the presence of a fever. Here are the top reasons people experience chills but do not have a fever.

What if I have the Chills but no Fever? – 5 Reasons for the Condition

#1 Undiagnosed Hypothyroidism

Hypothyroidism is one of the most undiagnosed diseases in modern society. This health condition occurs when the thyroid doesn’t produce enough T3 and T4 hormones that regulate our metabolism and, in turn, body temperature. Individuals with hypothyroidism often feel the cold more than healthy people.

Symptoms of Hyperthyroidism

Symptoms of hypothyroidism include the following:

Weight gain
Tiredness
Puffy face
Constipation
Joint and muscle pain
Dry skin and thinning hair
A drop in sweat production
Heavy or irregular menstrual periods
Fertility problems
Slowed heart rate
Depression
Enlarged thyroid

Speak to your doctor for a diagnosis if you experience any of the symptoms of hypothyroidism.

#2 Prolonged Cold Exposure

One of the leading causes of chills with no fever comes from over-exposure to cold temperatures. If you’re wearing wet clothes and standing in the wind, this will often result in chills.

If you’re outside in very cold weather without enough layers to keep you warm, you’ll start to feel chills. This is just like if you were to spend too much time bathing in cold water.

Hypothermia Risk

If you experience prolonged exposure to the cold, you risk the onset of hypothermia. This condition occurs when the body’s core temperature drops below 36.1 C (97 F) to 37.2 C (99 F). Hypothermia makes you feel tired, confused, and clumsy. Eventually, your organs start shutting down, and hypothermia can become a potentially life-threatening condition – seek medical attention immediately.

Hypothermia comes in four stages:

HT I: Mild Hypothermia, 95-89.6 F. Shivering is apparent.
HT II: Moderate Hypothermia, 89.6-82.4 F.
HT III: Severe Hypothermia, 82.4-75.2 F.
HT IV: Near Death. 75.2-59 F.
HT V: Death.

#3 Exercising in the Cold

Physical activity in cold weather without the right clothing is another cause of the chills with no fever. You might notice you feel cold after your body temperature cools when you finish exercising.

Intensive exercise in cold weather can disrupt your normal ability to maintain your body temperature, resulting in rapid cooling and the onset of chills. It’s best to get out of the cold immediately, especially if it’s windy, and change your clothes.

#4 Iron-Deficiency Anemia

Anemia is a medical condition describing a lack of iron in the blood. Iron builds new red blood cells and feeds oxygen to RBCs.

Common symptoms of iron deficiency anemia include chills in mild weather, looking pale, or waking up tired.

People develop iron deficiency anemia due to age, a poor diet, medication use, or chronic illness. Women are more at risk of developing anemia than men. Doctors use a blood test to confirm a diagnosis of iron-deficiency anemia.

Anemia Treatment

Doctors will recommend patients suffering from anemia eat foods rich in iron. They may even suggest an iron supplement to increase iron levels in the blood. In rare cases, the patient may require a blood transfusion.

#5 Malaria Infection

The final reason you might feel chills is due to a parasitic infection with malaria. Malaria has been responsible for killing more human beings throughout history than all causes of mortality combined.

If you recently traveled to a malaria area, this parasitic infection may be the cause of your chills.

Malaria Symptoms

Malaria typically comes in three stages.

In the cold stage, the person experiences the onset of chills.
In the hot stage, the person develops a fever.
The sweating stage.

If you notice these symptoms and recently traveled to a malaria hotspot, consult your doctor immediately. Some strains of the infection can be life-threatening.
