11 Important Causes of Shivering and Tips for Treating It

Do you know the reasons for shivering the body? When it is cold, the muscles of the body begin to contract and expand to produce heat. This causes the whole body or part of it to start shaking. Shivering can occur even on hot days, when the breeze is cool, or even when sitting in the shade.

Vibration is an involuntary and uncontrolled movement in the body. Hiccups and sneezing are other examples of involuntary body movements. In this article, we want to introduce you to the causes of chills and effective home remedies for them.

Reasons to shiver

You may think shivering occurs when you are in icy places. But this is not the only reason for this complication. Shivering can occur for a variety of reasons, which we will mention below.

Cold exposure

You may shiver if you are in cold places, such as the beach or pool, or outside on a cold day. You may also get this condition if your clothes get wet and damp. Shivering does not just happen when you are out and about.

You may shiver if the air conditioner is too cold or not warm enough when you are at home. As the human body ages, it becomes difficult to regulate temperature. This is true even in the elderly who are healthy. Diseases such as diabetes and heart disease make this problem worse.

As soon as you keep your body warm, your shivering will gradually go away. However, when you are exposed to extreme cold, and your body is continually shaking, you may experience complications such as a general drop in body temperature (frostbite) and frostbite, both of which are potentially dangerous. Other symptoms of these two conditions include:

  • numb
  • Skin discoloration
  • Stuttering (incomprehensible speech)
  • Severe drowsiness and boredom
  • Tingling and burning, especially in the fingers, toes, nose, and corners

If you think you may have a general fever or frostbite, you should seek medical attention immediately.


Aside from feeling cold, the most common cause of chills is fever, which doctors define as temperatures above 100 degrees Fahrenheit. Fever usually results from an infection, but inflammation or allergic reactions can also cause a rise in body temperature. Symptoms of the flu may accompany a fever, but in other cases, it has no other symptoms.

Drinking plenty of fluids and taking nonsteroidal anti-inflammatory drugs can help lower your body temperature. If the fever is accompanied by other symptoms such as neck cramps, rapid heartbeat, and shallow breathing, you should see a doctor within 24 hours. If no other symptoms occur, seeing a doctor is only necessary if the fever lasts for more than three days.

Side effects of medications

Shivering may occur as a result of taking certain medications. You may also experience chills if you take inappropriate doses of over-the-counter medications, herbal supplements, or over-the-counter medications.

Always check the side effects of the medications you are taking. Tell your doctor if you think you have chills because of the medications you are taking. Depending on the severity of the chills, you may need medical attention.

Intense physical activity

Two marathons or other sports requiring strenuous physical activity may cause body temperature changes, leading to chills. This reaction can occur in any climate but is more likely to occur when the temperature is too cold or too hot.

In scorching weather, overheating and dehydration cause this reaction, and in freezing weather, lower body temperature and dehydration cause this reaction. Other symptoms you may experience in both situations include:

  • Skewering body hair
  • Muscle cramps
  • Confusion
  • Weakness and fatigue
  • Nausea and vomiting

If you do not want to shiver when exercising, hydrate your body, and wear appropriate clothing. Do not exercise during the hottest or coldest hours of the day. Also, reduce the amount of time you spend doing strenuous physical activity.

 It is enough to hydrate the body and try to return the body temperature to normal. However, in some cases, you may need an intravenous injection for treatment.

Hypothyroidism (inactive thyroid)

Hypothyroidism is a condition in which the thyroid gland does not produce enough of a hormone responsible for regulating the body’s metabolism or promoting overall health. These conditions increase the body’s sensitivity to cold and consequently shivering. Other symptoms that can occur with hypothyroidism include:

  • Puffy face
  • Unreasonable overweight
  • Dry skin, nails, and hair
  • Weakness, pain, or muscle cramps
  • Memory impairment
  • Constipation

Hypothyroidism can be diagnosed through a blood test. This complication is treatable, and usually, to treat it, the patient must take medication daily. (Useful Foods For Those With Hypothyroidism Function)


Hypoglycemia occurs when blood sugar levels are abnormally low. This complication in people with diabetes may be a sign of the need to change medication and diet. However, it can also occur in non-diabetics.

In the case of hypoglycemia, immediate treatment is needed to return the blood sugar level to normal. One of the signs of hypoglycemia is a feeling of tremor and muscle weakness, which may be similar to the symptoms of chills. Other symptoms of low blood sugar include:

  • Sweating
  • Temperament and early suffering
  • heartbeat
  • Tingling around the mouth
  • Confusion
  • Attacks
  • Blurred vision


Malnutrition occurs when the body becomes deficient in nutrients. Malnutrition can occur due to inadequate access to nutritious food, or conditions that affect the body’s ability to absorb nutrients or eating disorders like anorexia.

An imbalance in nutrient intake causes the body not to function correctly. Other symptoms of malnutrition include:

  • Feeling tired or exhausted
  • Weakness
  • Difficulty concentrating
  • Pale skin
  • Skin rash
  • heartbeat
  • Feeling dizzy and dizzy or fainting
  • Murmuring and numbness of the joints and limbs
  • In women, irregular periods, heavy menstruation (heavy periods) or infertility

See a doctor if you think you may be malnourished. Malnutrition is a dangerous and challenging situation, and if left untreated, it can lead to several complications.

Intense emotional reactions

Shivering occurs when you have deep, intense emotional reactions to a situation. Feelings of fear and anxiety may be among the emotions that may lead to chills.

Shivering can also occur due to inspiring positive experiences, such as listening to music or inspiring speech. This situation is sometimes called excitement. Such emotional reactions may be due to the nervous system’s mechanisms that release dopamine (a neurotransmitter).

Blood infection (bloody stench)

Infectious poisoning is a severe reaction of the body to infection and often occurs in connection with infections of the lungs, skin, intestines, or urinary tract. One of the symptoms of blood infection is chills.

Other symptoms include confusion, sweating or sweating, pain, increased heart rate, and shortness of breath. A blood infection is an emergency condition, and people need immediate antibiotic treatment in the hospital.


Involuntary vibration and vibration of the body can be caused by a brain’s neurological disease called tremor. The disease, which affects about 10 million people in the United States, causes tremors in the arm, leg, body, or voice. Major tremors can be caused by Parkinson’s disease symptoms, a disorder that affects the brain’s part and progresses gradually.

Shivering after anesthesia

Shivering can occur after a person regains consciousness after general anesthesia. The body temperature may drop during surgery, which causes the person to shiver after regaining consciousness.

Anesthesia can also affect the body’s ability to regulate temperature, making it difficult for the body to warm up quickly after surgery. Doctors usually check a person’s body temperature after regaining consciousness and, if necessary, use blankets and heaters to relieve chills.

Home remedies for chills

Shivering is usually temporary and may occur due to some medical condition. If you are concerned about this, tell your doctor about any other symptoms you may have. If shivering occurs due to fever, hypoglycemia, or the experience of strong emotions, it can be treated by treating the underlying cause. You can also do the following to treat chills at home:

  • Relieve fever by drinking plenty of fluids and taking nonsteroidal anti-inflammatory drugs
  • Return blood sugar levels to normal by eating foods that help maintain blood sugar.
  • Drink lemon and hot water
  • Use extra blankets
  • Sit in a secluded place and breathe slowly to restore calm

Shivering can be more severe in the elderly or people with underlying diseases because they are less able to regulate their body temperature; So they may feel colder. Keeping warm in cold weather is essential for maintaining good health. Fever causes the heart rate to rise and breathe faster, which can be severe and dangerous in people with heart or lung problems.
