Your Ultimate Guide To Understanding Normal Body Temperature: Causes, Symptoms, And Prevention

Body temperature is a vital sign that indicates the body's ability to produce and dissipate heat. A normal body temperature for a healthy adult is around 98.6°F (37°C), but it can vary slightly depending on factors such as time of day, activity level, and individual differences. In this guide, we will discuss the causes, symptoms, and prevention of abnormal body temperature.

Causes of abnormal body temperature:

Fever: The most common cause of abnormal body temperature is a fever, which is a sign of an infection or inflammation in the body. A fever is defined as a body temperature above 100.4°F (38°C).
Hypothermia: A low body temperature, known as hypothermia, can occur in cold environments or due to certain medical conditions. A body temperature below 95°F (35°C) is considered hypothermia.
Hyperthyroidism: An overactive thyroid gland can cause the body to produce too much heat, leading to a high body temperature.
Medications: Certain medications, such as antipsychotics and antidepressants, can affect body temperature regulation.
Trauma: Serious injury or surgery can cause the body to produce too much heat as a response to the trauma.

Symptoms of abnormal body temperature:

Fever: Symptoms of a fever can include sweating, chills, headache, muscle aches, and fatigue.
Hypothermia: Symptoms of hypothermia include shivering, numbness, confusion, and slow breathing.
Hyperthyroidism: Symptoms of hyperthyroidism include weight loss, rapid heartbeat, and sweating.

Prevention of abnormal body temperature:

Fever: The best way to prevent a fever is to practice good hygiene, such as washing your hands frequently, and avoiding close contact with people who are sick.
Hypothermia: To prevent hypothermia, it is important to dress warmly in cold weather, and avoid staying out in the cold for prolonged periods of time.
Hyperthyroidism: To prevent hyperthyroidism, it is important to manage any underlying medical conditions that can cause an overactive thyroid gland.
Medications: If you are taking medications that can affect body temperature regulation, it is important to follow your doctor's instructions and monitor your body temperature regularly.
Trauma: To prevent abnormal body temperature due to trauma, it is important to take steps to prevent injuries and accidents.

In conclusion, abnormal body temperature can be caused by fever, hypothermia, hyperthyroidism, medications, and trauma. It is important to be aware of the symptoms and take the necessary steps to prevent abnormal body temperature. If you have a fever or other symptoms of abnormal body temperature, it is important to seek medical attention.

CRP Test Meaning and When to Do It

If you’ve recently had blood work or your doctor suspects an infection or inflammation, they may have recommended a CRP test. But what is it? Why is it important? And when exactly should you get it done?

Let’s simplify the medical jargon and walk you through the CRP test meaning and when to do it, especially in the Indian healthcare context.

What Is a CRP Test?

CRP stands for C-reactive protein. It is a substance produced by your liver in response to inflammation in the body.

The CRP test is a blood test that measures the amount of C-reactive protein in your blood. High levels of CRP usually mean there’s inflammation in your body, which could be due to an infection, injury, or a chronic disease like arthritis.

High CRP = Inflammation Alert

This test doesn’t tell you what’s causing the inflammation—it simply tells you that something is wrong, and further testing might be needed.

What Does the CRP Test Detect?

While CRP is a general marker, it is helpful in detecting:

Bacterial or viral infections
Autoimmune disorders like rheumatoid arthritis or lupus
Inflammatory bowel diseases
COVID-19 severity
Heart disease risk (especially with high-sensitivity CRP or hs-CRP)

When Should You Do a CRP Test?

You should get a CRP test done when:

You have fever or chills that won’t go away
You’re showing signs of infection like cough, swelling, or pain
Your doctor is monitoring an autoimmune disease
You’re recovering from surgery or injury
Your doctor is checking inflammation due to chronic disease
You are showing COVID-like symptoms (to assess severity)

Normal CRP Levels:

CRP Level	Interpretation
Below 1 mg/L	Low risk of inflammation
1–3 mg/L	Moderate risk
Above 3 mg/L	High inflammation or infection present
Above 10 mg/L	May indicate serious infection or disease

Note: For heart disease risk, a high-sensitivity CRP (hs-CRP) test is used.

Is Fasting Required for the CRP Test?

No, fasting is not required. You can take the CRP test at any time of day, unless it is being done with other tests that require fasting (like blood sugar or cholesterol).

Eat more fruits, vegetables, and whole grains
Cut down on sugar and processed food
Include omega-3 rich foods like flaxseed and fish
Exercise regularly
Manage stress and sleep better
Quit smoking and limit alcohol

5 Most Asked Questions About the CRP Test

1. What is the CRP test used for?

CRP tests are used to check for inflammation due to infections, autoimmune diseases, and to monitor treatment effectiveness.

2. What causes a high CRP level?

Infections, chronic inflammation, surgery, injuries, and lifestyle diseases like diabetes and heart disease.

3. Is a CRP test painful?

No. It’s a simple blood test and usually takes just a few minutes.

4. How long does it take to get CRP test results?

Most labs deliver CRP results within 24 to 48 hours.

5. Can CRP levels return to normal?

Yes, with proper treatment and lifestyle changes, CRP levels can go back to the normal range.
