Physical health is crucial for everyone, yet various factors often lead to impairments in our physical well-being in daily life. Many individuals have experienced shivering throughout their bodies, which can be attributed to various reasons such as hypoglycemia due to excessive hunger, illnesses like colds, excessive tension or anxiety, and so on.

Causes of Body Shivering

1. Hypoglycemia

When the blood sugar level falls below the normal range, the body may involuntarily shiver, accompanied by symptoms such as dizziness, sweating, headache, and rapid heartbeat. These are manifestations of hypoglycemia, which are commonly observed in diabetic patients who inject insulin. Injecting too much insulin can rapidly lower blood sugar levels or trigger hypoglycemia. Other factors that can cause hypoglycemia include irregular eating habits, excessive alcohol consumption, excessive exercise, and insufficient carbohydrate intake. Eating foods that can quickly raise blood sugar levels can help avoid further deterioration.

2. Respiratory Infection

After the respiratory tract is infected by viruses or bacteria, it can cause bronchial swelling, which may also trigger bouts of shivering accompanied by coughing, chest pain, and other respiratory issues.

3. Body Fluid Loss

Severe fluid loss or dehydration is primarily manifested by shivering and trembling. This is the body's attempt to maintain a normal body temperature and makes the body more sensitive to changes in the external environmental temperature. This condition is more common in individuals after long-distance running (such as marathon races) as their bodies are severely dehydrated. Other possible symptoms include headaches, muscle spasms, dark-colored urine, and nausea.

4. Anemia

Some people may suddenly feel a chill in hot weather, accompanied by involuntary shivering and feelings of weakness or fatigue. This can be due to anemia caused by iron deficiency, medically known as low hemoglobin. Hemoglobin contains iron and is a special protein that transports oxygen within red blood cells. Individuals with low iron levels often experience frequent shivering and cold hands and feet.

5. Food Poisoning

Sometimes, the body may suddenly shiver without showing signs of fever, which can also be attributed to food poisoning. Some patients with food-borne illnesses may experience alternating hot and cold symptoms, while others may not experience significant changes in body temperature. In addition to involuntary shivering, symptoms such as diarrhea, vomiting, and abdominal pain may also occur.

6. Medication

Some prescription medications can have side effects, especially when taken in large doses, which can lead to involuntary shivering.

7. Urinary Tract Infection

Urinary tract infection is an inflammatory response caused by bacterial invasion of the urinary tract, which can manifest as painful urination, bacterial urine or purulent urine, and sudden chills during urination. If the infection spreads to the kidneys, patients may also experience fever and involuntary shivering.

8. Parasitic Infection

Parasitic infections such as toxoplasmosis are common, but they may not manifest any symptoms in individuals with a healthy immune system. However, in individuals with weakened immune systems, they may experience fatigue, muscle pain, gland swelling, fever, and chills.

9. Mental Illness

Apart from physical conditions, individuals may also experience involuntary shivering due to emotional issues such as anxiety and unexplained fears, even without fever. Other symptoms may include dry mouth, nervousness, and reduced body temperature.

Solutions for Body Shivering

1. Body Fluid Loss: Replace lost fluids by drinking small amounts of water slowly and consume electrolyte solutions to maintain electrolyte balance in the blood.

2. Anemia: Treat iron-deficiency anemia by supplementing with iron. Take these supplements during meals and combine them with vitamin C to enhance absorption.

3. Food Poisoning: In most cases, symptoms of food poisoning improve within a few days. However, repeated diarrhea can lead to significant fluid and electrolyte loss. To avoid this, it is essential to replenish electrolyte solutions promptly. If symptoms persist or worsen, seek medical attention immediately.

4. Medication Overdose: If shivering occurs after taking medication, consult a doctor to determine if dosage adjustments are necessary. If the symptoms persist, discuss switching medications with your doctor.

5. Mental Stress: Methods like meditation or relaxing yoga can effectively relieve anxiety.
