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.

Insomnia in Teens and How to Manage It

Insomnia in Teens and How to Manage It

Sleep is essential for growing teens, yet many struggle to get enough of it. From school stress to social media scrolling, teenagers today face multiple challenges that affect their sleep. One of the most common sleep disorders among adolescents is insomnia—the inability to fall asleep, stay asleep, or wake up feeling rested.

In this blog, we’ll break down the causes, effects, and simple strategies to handle insomnia in teens and how to manage it naturally.

 

What is Insomnia?

Insomnia is a sleep disorder that makes it hard to fall asleep, stay asleep, or get quality rest. Teens with insomnia often feel tired during the day, even if they’ve spent enough time in bed.

There are two main types:

  • Short-term insomnia: Lasts for a few days or weeks, often triggered by stress or changes in routine.
     

  • Chronic insomnia: Occurs at least three times a week for over three months.
     

 

Why Is Insomnia Common in Teens?

Teenagers go through many physical, emotional, and social changes. All these factors can disturb their sleep:

1. Hormonal Shifts

During puberty, the sleep hormone melatonin is released later at night. This shifts the body clock, making teens naturally want to sleep and wake up later.

2. Screen Time

Excessive use of phones, tablets, or laptops before bedtime exposes the brain to blue light, which delays melatonin release and interferes with sleep.

3. Academic Stress

Homework, exams, and performance pressure can cause anxiety and overthinking at night, preventing restful sleep.

4. Caffeine Intake

Energy drinks, tea, coffee, and cola consumed in the evening can make it difficult to fall asleep due to their stimulating effects.

5. Mental Health Issues

Anxiety, depression, and emotional distress are often linked with poor sleep in teens.

 

Signs of Insomnia in Teenagers

  • Difficulty falling asleep at night
     

  • Waking up multiple times during the night
     

  • Feeling tired or sleepy during the day
     

  • Irritability or mood swings
     

  • Trouble focusing in school
     

  • Frequent headaches or stomach issues
     

  • Increased use of stimulants (coffee, energy drinks)
     

 

How Insomnia Affects Teens

Sleep deprivation can harm a teen's physical and mental health. Here are a few ways it affects their well-being:

  • Poor concentration in school
     

  • Weakened immunity
     

  • Increased risk of depression and anxiety
     

  • Weight gain due to hormonal imbalance
     

  • Risky behaviors due to impaired judgment
     

Teens who consistently sleep less than 7–8 hours are more likely to face emotional and academic challenges.

 

Natural Ways to Manage Insomnia in Teens

Thankfully, insomnia doesn’t always need medication. Many teens can improve their sleep with simple lifestyle changes.

1. Set a Regular Sleep Schedule

Encourage going to bed and waking up at the same time every day—even on weekends. This helps reset the body’s internal clock.

2. Limit Screen Time Before Bed

Avoid phones, TVs, and tablets at least 1 hour before bedtime. Use “night mode” or blue light filters if screen use is necessary.

3. Practice Relaxation Techniques

Deep breathing, meditation, gentle yoga, or reading a book before bed can calm the mind and prepare the body for sleep.

4. Watch Food and Drink

Avoid heavy meals, sugar, or caffeine in the evening. A light snack like warm milk, bananas, or almonds can promote better sleep.

5. Get Daily Exercise

Physical activity during the day can improve sleep quality—but avoid intense workouts right before bedtime.

6. Create a Sleep-Friendly Environment

Keep the bedroom cool, dark, and quiet. Use blackout curtains, soft bedding, and remove distractions like phones or bright lights.

 

When to See a Doctor

If your teen’s insomnia lasts longer than 3 weeks or affects their daily life, school, or mood, it’s important to consult a doctor or sleep specialist. Underlying conditions like anxiety, ADHD, or depression might need professional care.

 

Lab Tests That May Help

If your teen complains of constant fatigue or disrupted sleep, you might consider lab tests to rule out medical reasons such as:

  • Thyroid Function Test (for hormonal imbalance)
     

  • Vitamin D & B12 Tests (deficiency can affect sleep)
     

  • Stress Hormone Panel (Cortisol)
     

  • Iron Levels (especially in girls)
     

These tests are available through diagnostic providers like Thyrocare on platforms like SecondMedic.

 

Helping Teens Build Healthy Sleep Habits

As a parent, here’s how you can support better sleep:

  • Encourage open conversations about school pressure or emotional issues.
     

  • Set boundaries for screen use, especially at night.
     

  • Make the home environment calm and supportive before bedtime.
     

  • Lead by example—follow healthy sleep habits yourself.
     

 

Quick Tips for Teens

  • Sleep 8–10 hours every night
     

  • Don’t study in bed
     

  • Use a sleep diary or app to track sleep patterns
     

  • Avoid naps longer than 30 minutes in the day
     

  • Try journaling to clear the mind before sleep
     

 

Conclusion

Teenage insomnia is more common than many people realize. Fortunately, with the right support, structure, and healthy routines, it can be managed without medication.

If your teen shows signs of poor sleep, don’t ignore it. Better sleep leads to better mood, focus, and health.

So, if you’re wondering how to support better sleep for your child, remember to understand insomnia in teens and how to manage it the natural way—with empathy, good habits, and expert care when needed.
