Why do I feel alternately cold and hot all over my body?

Generally, feeling both cold and hot throughout the body may be caused by early signs of fever, perimenopausal syndrome, common cold, enteritis, lobar pneumonia, or other conditions. Patients can receive symptomatic treatment based on the specific underlying cause. Detailed analysis is as follows:

1. Early Signs of Fever

If a viral or bacterial infection occurs, it may lead to body fever. Before the onset of fever, some patients may experience alternating sensations of heat and chills. It is recommended that patients take medications such as ibuprofen granules or antiviral oral liquid, drink plenty of plain water, and promote metabolism to aid recovery.

2. Perimenopausal Syndrome

In women around the age of 50, this condition may be due to perimenopausal syndrome. During menopause, hormonal fluctuations can cause vasomotor symptoms, manifesting as sudden hot flashes followed by chills. Patients are advised to keep warm, engage in moderate physical exercise, maintain a healthy diet, and follow a regular sleep schedule.

3. Common Cold

If individuals do not pay attention to staying warm, their immune resistance may decrease, leading to a common cold. Symptoms of a cold often include runny nose, sore throat, cough, and fever. As fever worsens, patients may alternately feel cold and hot. It is recommended that patients follow medical advice and use medications such as ibuprofen sustained-release capsules or cold and fever tablets for treatment.

4. Enteritis

Enteritis is caused by infection or inflammation, which activates the immune system to fight the infection or respond to inflammation. Immune activity often leads to an increase in body temperature, causing fever. Enteritis is usually accompanied by diarrhea and vomiting, which may result in fluid loss and dehydration. Dehydration can affect the body's temperature regulation, making the patient feel cold. Patients may take medications such as lactase tablets or kushen capsules under a doctor’s guidance.

5. Lobar Pneumonia

Lobar pneumonia is primarily caused by Streptococcus pneumoniae and may lead to sudden high fever, chest pain, rust-colored sputum, and difficulty breathing. Therefore, patients with lobar pneumonia may experience alternating chills and fever. It is recommended that patients follow medical advice and use antibiotics such as amoxicillin or levofloxacin tablets for treatment.

In addition, neurological dysfunction may also cause alternating sensations of cold and heat throughout the body. If symptoms persist without improvement, patients should seek timely medical attention and avoid delaying treatment or self-medicating, which could lead to worsening of the condition.
