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.

Top 5 Lab Tests You Can Book from Home in India

Healthcare in India has become more convenient with the rise of at-home lab test bookings. Instead of traveling to diagnostic centers, many people now prefer the comfort of home sample collection. This shift not only saves time but also minimizes exposure to infections in crowded waiting rooms.

Whether it's for preventive health checkups or managing chronic conditions, booking lab tests from home is now easier than ever. Here are the top 5 lab tests you can book from home in India and why they matter.

1. Complete Blood Count (CBC)

The Complete Blood Count test is one of the most commonly recommended blood tests by doctors. It gives a snapshot of your overall health by measuring various components of your blood, including:

Red blood cells (RBCs)
White blood cells (WBCs)
Hemoglobin
Hematocrit
Platelets

This test helps detect conditions such as anemia, infections, inflammation, and even certain cancers. If you're feeling weak, experiencing frequent infections, or suffering from fatigue, a CBC test can offer early clues. Most labs, including Thyrocare, offer CBC as part of their health packages for easy home collection.

2. Lipid Profile Test

A lipid profile checks the levels of cholesterol and triglycerides in your blood. These fats are crucial indicators of heart health. The test measures:

Total cholesterol
LDL (bad cholesterol)
HDL (good cholesterol)
Triglycerides
VLDL and other ratios

High cholesterol often comes without any symptoms but increases your risk for heart attacks, strokes, and blockages. A lipid profile test from home helps monitor these levels and assess cardiovascular risk early on. Regular screening is essential if you have a family history of heart disease, lead a sedentary lifestyle, or consume high-fat foods.

3. Thyroid Function Test (T3, T4, TSH)

Thyroid disorders are increasingly common, especially among women. An underactive or overactive thyroid can lead to fatigue, weight gain, mood changes, or irregular periods. A thyroid panel tests the following hormones:

T3 (Triiodothyronine)
T4 (Thyroxine)
TSH (Thyroid Stimulating Hormone)

These levels indicate how well your thyroid gland is functioning. Early diagnosis can prevent complications and help maintain energy levels and metabolic balance. Booking this test from home allows you to manage symptoms discreetly and conveniently.

4. Liver Function Test (LFT)

The liver is responsible for filtering toxins, metabolizing drugs, and aiding digestion. When it’s not working properly, it may not show immediate symptoms. That’s where an LFT comes in. It checks for:

ALT and AST (liver enzymes)
Bilirubin
Albumin and total protein
Alkaline phosphatase

An abnormal result could indicate liver damage, infections like hepatitis, or alcohol-related issues. Whether you’re on medication or consume alcohol frequently, a liver function test is essential. Home sample collection makes it easier to get tested without delay or discomfort.

5. HbA1c (Glycated Hemoglobin) Test

For people with diabetes or those at risk of developing it, the HbA1c test is crucial. It measures average blood sugar levels over the past 2 to 3 months, unlike a regular blood sugar test that only gives current readings.

An HbA1c level:

Below 5.7% is considered normal
Between 5.7% and 6.4% suggests prediabetes
6.5% or higher indicates diabetes

This test is important for long-term diabetes management. With at-home testing, patients can monitor their glucose trends more regularly and adjust their treatment plans as needed.

Why Home Testing is the Future of Diagnostics

Booking lab tests from home is not just about convenience. It’s about proactive health management. The COVID-19 pandemic showed us the importance of staying indoors when unwell, and home diagnostics made that possible. These services offer:

Certified technicians for safe sample collection
Digital reports with fast turnaround times
Affordable health checkup packages
Transparent process with easy tracking

Thyrocare and platforms like SecondMedic have played a key role in expanding access to reliable at-home testing across India.

Who Should Book Lab Tests from Home?

Busy professionals who don’t have time for clinic visits
Elderly patients who need regular testing
Women managing pregnancy or hormonal imbalances
Diabetics and heart patients needing frequent checkups
Anyone prioritizing hygiene, safety, and convenience

These services are also ideal for rural and semi-urban areas where healthcare infrastructure may be limited.

Final Thoughts

Modern healthcare is all about accessibility and early detection. Whether you're checking cholesterol levels, managing thyroid conditions, or tracking diabetes, at-home lab tests make it easier than ever. All it takes is a few clicks and a short appointment with a trained sample collector.

You don’t need to delay health monitoring anymore. With trusted providers like Thyrocare offering safe and certified diagnostics, your health check can start at home.

If you’re wondering which tests are essential, start with these top 5 lab tests you can book from home in India and stay a step ahead in your health journey.
