Causes Of Internal Body Heat And How To Overcome Them

December 5, 2020

Updated May 2023

Internal body heat can be caused by a variety of factors, including stress, dehydration, and certain medical conditions. Discover how to overcome this uncomfortable sensation with our helpful tips.

What causes you to have internal body heat, and why is it a symptom that so little is understood? Why would anyone experience excessive night sweats despite normal external temperature? Or have a sensation of “internal heat” over a part of the body – without a fever?

What is “Internal Heat”?

This is a situation when an individual experiences an uncomfortable sensation of excess body heat.

It may happen all over the body. In some cases, it may just happen in some specific part of the body only.

Common examples are in one part of the body, like the tummy or the chest; then, it gradually moves to other parts of the body.

But, you might say – isn’t this the same as having a fever?

A fever is a condition when the body temperature is abnormally high.

However, sometimes you may feel the sensation of internal body heat, and when you a temperature check, it is normal.

So while a fever can cause internal body heat, not all types of internal body heat are due to a fever.

Watch this video to learn more about Internal Heat Treatment and Causes.

Some Causes of Internal Heat

Internal heat could be described in a lot of ways. Men and women experience the feeling of internal body heat and express it in different ways.

It’s also described as “hot flushes” for one group of women.

So one of the possible causes of ‘internal heat’ – depending on the individual’s age and gender – is Menopause.

This is because hot flushes occur in about 7 out of 10 women during menopause.

According to this study – they occur more commonly in women in the United Arab Emirates and Nigeria1.

However, Menopause is not the only reason for internal heat.

Other reasons include:

  • Spicy food – it’s thought spicy foods such as those containing hot peppers or spices like hot curry could cause internal heat.
    • Onions and garlic have also been thought to do the same.
    • Hot peppers contain Capsaicin, a compound that also has some medicinal uses.
    • It is effective as a pain-relieving agent for joint or muscle sprains when used as a cream or patch.
    • Capsaicin produces local heat in the affected area with some benefits.
  • Another cause of the sensation of internal heat is a serious or chronic illness like cancer.
  • In some mental health conditions, people may experience a sensation of ‘internal heat’ or other sensations.
  • A problem with how your Thyroid gland works (overactive Thyroid or hyperthyroidism) can also give you a feeling of abnormal internal heat.
  • Pregnancy is another condition where the term also comes up. A woman’s body temperature may go up by a few degrees when she is pregnant, which could lead to the feeling of internal heat.

Other symptoms you may have with internal heat include ‘reddish or dark discolouration to the skin’, a rapid heartbeat and increased anxiety. Night sweats (described below) may also happen.

And there are several other causes of “internal heat”. Click HERE to learn more.

What are ‘Night Sweats’?

The body has sweat glands located all over your skin.

They make sweat under stimulation from our brain under circumstances.

Sweat is one of the reactions from your body to help it cool down when it feels overheated.

Normal situations for you to sweat are exercise, stress, fear, or even certain foods.

Why Worry About Night Sweats?

When sweating happens without the usual trigger, it suggests there may be something wrong.

Sweating may happen at night if you are in a warm room or if you suddenly wake from a bad dream.

However, when it appears spontaneously, you should pay attention.

You should become concerned when the amount of night sweats does not match what is expected from the environmental temperature.

Night sweats can sometimes happen with internal body heat.

Some Causes of Night Sweats

Night sweats can happen for a lot of reasons.

Something changes the way our bodies create sweat, leading to sweating in abnormal circumstances.

Examples are:

  • Chronic infections like Tuberculosis
  • Problems affecting the Immune system
  • Some types of cancer, such as Leukaemia
  • When a woman undergoes Menopause.

Having internal heat and night sweats symptoms is uncommon in menopausal women and can be highly distressing.

You should report unexplained night sweats to your doctor so they can arrange tests to determine the cause.

Simple Remedies for Internal Heat and Night Sweats.

Now this will depend on the specific causes of the problem, but generally, the following will help:

  • Wear light clothing.
  • Keep your bedroom cool at night.
  • Take a cooling shower before bed.
  • Try to rest as much as possible to reduce overall stress levels.
  • Avoid triggers like spicy food, caffeine, smoking and alcohol.
  • Regular exercise and healthy eating.
