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.

Do Late-Night Meals Cause Weight Gain

Do Late-Night Meals Cause Weight Gain? Let’s Uncover the Truth

Many of us have a habit of snacking late at night or even having a full meal right before bed. Whether it’s a busy schedule, late-night cravings, or watching movies with snacks, eating late has become quite common. But the big question is—do late-night meals cause weight gain?

Let’s explore what science says, how your body responds to late meals, and tips to manage your eating habits for better health and weight control.

 

Why We Eat Late at Night

In today’s fast-paced life, late-night eating often happens because of:

  • Long working hours or night shifts
     

  • Skipping meals during the day
     

  • Emotional eating or stress
     

  • Social gatherings or weekend habits
     

While occasional late-night eating may not harm you, making it a routine could have consequences—especially if the food choices aren’t healthy.

 

How Your Body Works While You Sleep

Your body doesn’t shut down at night—it continues working. However, the metabolism slows down because your body prepares for rest, not digestion. Late-night meals, especially heavy or sugary ones, are digested more slowly.

During sleep, your energy demand is low, so the extra calories consumed at night are more likely to be stored as fat rather than burned for energy.

 

Late-Night Eating and Weight Gain: What's the Link?

Several studies show that when you eat is just as important as what you eat. Here’s why eating late may contribute to weight gain:

Calorie Surplus

Late-night meals usually come after you've already eaten enough during the day. So, you’re adding more calories than your body needs—leading to weight gain.

Poor Food Choices

People tend to eat unhealthy foods at night—like chips, ice cream, sugary drinks, or fast food. These high-calorie items with little nutrition easily lead to fat storage.

Hormonal Imbalance

Late eating can affect hormones like insulin, leptin, and ghrelin, which regulate hunger and fat storage. Disrupted hormonal patterns can make you feel hungrier the next day and crave more junk food.

Disrupted Sleep

Heavy meals before bed can cause bloating, acidity, or indigestion—leading to poor sleep. Poor sleep affects metabolism, increases hunger hormones, and makes weight gain more likely.

 

Common Myths About Late-Night Eating

Let’s bust a few myths:

Myth: Eating after 8 PM always causes weight gain.
Fact: It depends on how much and what you eat. A light snack at 9 PM is very different from a greasy burger at midnight.

Myth: Your body stores everything as fat at night.
Fact: If your total daily calories are under control and your food choices are healthy, you won’t automatically gain weight.

 

When Late-Night Meals Might Be Okay

Late-night eating isn’t always harmful—especially if:

  • You’ve had a long gap between meals
     

  • You're genuinely hungry (not just bored)
     

  • You choose a light and balanced snack like:
     

    • A handful of almonds
       

    • Greek yogurt
       

    • A banana or boiled egg
       

    • Warm turmeric milk
       

These foods are low in calories and promote better sleep.

 

Best Time to Eat Dinner

Nutrition experts recommend having your last major meal 2 to 3 hours before bedtime. For example, if you sleep at 10:30 PM, aim to finish dinner by 7:30–8:00 PM.

This gives your body enough time to digest food before you lie down, preventing bloating, heartburn, and excess fat storage.

 

Tips to Avoid Late-Night Overeating

Here’s how to manage your night-time hunger:

1. Eat Balanced Meals During the Day

Don’t skip breakfast or lunch. When you eat regularly, you’re less likely to feel hungry late at night.

2. Hydrate Properly

Thirst is often mistaken for hunger. Drink water before reaching for a snack.

3. Plan Your Dinner Time

Set a regular time for dinner. Make it a light, protein-rich meal with veggies.

4. Don’t Eat Out of Boredom

Keep yourself busy. Sometimes a walk, a warm shower, or reading helps more than food.

5. Sleep on Time

Late sleepers are more likely to snack. A fixed sleep schedule helps control hunger hormones.

 

Healthy Late-Night Snack Ideas

If you truly need something to eat before bed, try:

  • Low-fat yogurt
     

  • Whole-grain crackers with peanut butter
     

  • A small fruit like apple or kiwi
     

  • Herbal teas like chamomile or tulsi
     

Avoid spicy, fried, or sugary foods—they’ll disrupt sleep and digestion.

 

What You Can Do for Weight Control

If you're struggling with weight or digestion, consider a weight management test panel. Thyrocare (via SecondMedic) offers:

  • Thyroid test – to rule out hormonal causes
     

  • Vitamin & lipid profile – for metabolic insight
     

  • Fasting glucose & HbA1c – for sugar levels
     

These tests help identify if late-night eating is affecting your metabolism or sugar levels.

 

Conclusion

So, do late-night meals cause weight gain? The answer depends on what, how much, and how often you eat late at night. Eating a heavy or high-calorie meal before bed regularly can absolutely lead to weight gain over time.

The key is to eat mindfully, stick to healthy choices, and maintain a consistent eating and sleeping schedule. Occasional late-night snacks won’t hurt—but turning them into a habit will.

To protect your health and manage weight, be aware of what you eat, and when you eat—because yes, do late-night meals cause weight gain? Absolutely, if you're not careful.
