Chills or shivering are caused by the rapid alternation of muscle contractions and relaxation, as the body's way of trying to warm itself in cold conditions. Chills are often associated with a fever, but it is not always a fever that is the cause of the chills, as it can be caused by many other causes. Let's get to know it together.
Causes of chills
Chills without fever can be caused by:
exposure to cold
It is normal to get chills in a cold place or if the air conditioning is too cold. The chills often go away when you feel warm. But if you constantly shiver when exposed to extreme cold, it may indicate that you may have some complications, such as hypothermia or frostbite.
Other symptoms of these conditions include:
- numbness in the extremities.
- Changes in skin color.
- slurred speech.
- severe drowsiness.
Side effects of some medications
Chills may be caused by taking certain medications or supplements. So be sure to consult your doctor first before taking any medication or supplement.
The reaction of the body to intense physical activity
Running a marathon or extreme sports that require extreme physical exertion may cause changes in basal body temperature, leading to chills, particularly:
- At high temperatures: as a result of heat stress and drought.
- In cold temperatures: due to hypothermia and dehydration.
Other symptoms you may experience include:
- Muscle spasm.
- dizziness.
- Tired.
- nausea.
You can avoid this by staying hydrated, wearing the right clothes for exercise, and exercising in the right place and for the right amount of time.
One of the causes of chills: Hypothyroidism
Thyroid hormones affect the regulation of metabolic rate, so patients with hypothyroidism often experience chills. Other accompanying symptoms include:
- Facial swelling.
- overweight.
- Dry skin, nails, and hair.
- Muscle weakness, pain, or stiffness.
- Depression.
- memory problems.
- constipation.
- Hypoglycemia.
Its common symptoms include:
- feeling shivering.

One of the causes of chills: is an emotional reaction
Chills can occur if you experience a very intense or emotional site, due to feelings of fear, anxiety, or surprise. This reaction is caused by neurobiological mechanisms that lead to the release of dopamine.
Chills or shivering are caused by the rapid alternation between muscle contractions and relaxation. Chills are often associated with a fever, but it is not always a fever that is the cause of the chills, as it can be caused by many other causes.
