Are You Cold, Then Hot? These 4 Conditions May Affect Body Temperature

22nd August 2015

When your body is exposed to low temperatures for several hours, it loses heat faster than it can produce it. So your body temperature may drop to dangerous levels.

This leads to a condition called hypothermia. Which appears when the temperature drops below 95 degrees F, or 35 degrees C. Hypothermia manifests through excessive shivering, weak pulse, slowed breathing and speech. It also includes excessive fatigue, stumbling, and clumsiness. It can be fatal if the body temperature remains low for several hours.

Although hypothermia occurs only in extreme situations. It’s not uncommon for one to experience frequent variations in body temperature. Being too cold, then too hot, and again too cold may state that something is not working well inside the organism.

Minor changes in body temperature are normal

In a healthy adult, the body temperature varies between 97.7 and 99.5 F, or 36.5 and 37.5 C. This value is called normothermia. It may vary by about 0.9 F (0.5 C) during the day. Also, it can be a little lower in the morning and higher in the afternoon and evening. The lowest value of one’s body temperature is usually registered during the second half of the sleep cycle. When the metabolic function slows down to allow the body to recover and recharge its energy reservoirs.

Body temperature varies with the season. Values are higher after a training session and physical activities, especially if you use Hypervibe whole-body vibration. In the same manner, eating and drinking increase body temperature. As the body burns those calories and produces energy and heat. But, fasting decreases body temperature. So people who are on a diet that restricts calorie intake may have lower body temperature values.

The temperature of the human body decreases with age. It is sensitive to changes in hormone levels, being higher after ovulation. Sleeping in a cold room decreases body temperature, and wearing more clothing raises these values. All these variations are normal and are not a sign of disease. There are, yet, certain conditions that may also lead to changes in body temperature. So it’s time to take a look at some threatening causes of unstable body temperature.



If you feel cold, then you’re hot without adjusting the room temperature, it may be due to a thyroid problem. The thyroid handles regulating the metabolism, heart rate, and body temperature. It’s an endocrine gland located above the collarbone.

When this gland produces too much thyroid hormone, your temperature increases. So, when the production of T3 and T4 decreases, your body temperature drops as well. These two hormones control the way your body uses its energy. Low levels of thyroid hormones lead to slow metabolism. That also includes symptoms like fatigue and weakness, depression, constipation, increased sensitivity to cold, brittle nails and hair, and heavier menstrual flow in women.

Left untreated, hypothyroidism can lead to puffiness in the face, hands, and feet, obesity, thickened skin, decreased sense of taste and smell, fertility problems, joint pain, and even heart disease. It’s so important to check your thyroid hormone levels. If you experience hot flashes, night sweats and you’re very sensitive to cold temperatures.


Adrenal fatigue is a common cause of hypothyroidism. Exhausting your adrenal glands affects the production of thyroid hormones. These two glands are located on top of your kidneys. They produce hormones like cortisol which regulates metabolism. And also dictates how your body reacts to stress, and adrenaline. Which is also involved in stress management.

Tired adrenals can’t manage the stress and energy requirements. They force the organism to conserve some of its energy. The lower energy output reduces the workload of the body. This is useful for your body but leads to low thyroid function. Thus to low body temperature.

Adrenal exhaust manifests through high levels of fatigue. And difficulty getting up in the morning, even after a restful sleep. Inability to handle stress leads to increased emotional and physical stress cravings for salty foods. Other ways high energy levels in the evening, due to spikes in cortisol levels in the late afternoon. As well as immunity problems and frequent inflammation.

Other potential symptoms of adrenal fatigue are allergies and respiratory problems. Other includes:

  • dry skin;
  • dark circles under the eyes;
  • joint pain;
  • frequent urination;
  • extreme tiredness after exercise;
  • dizziness;
  • loss of muscle tone;
  • low blood sugar levels and hypotension;
  • lower back pain;
  • numbness in fingers;
  • poor circulation;
  • low sex drive and weight gain.



It is well known that people affected by type 1 diabetes tend to have lower body temperatures. Those suffering from type 2 diabetes also tend to have fluctuations in core body temperature. What happens when the levels of blood sugar aren’t controlled. And when the body doesn’t produce or doesn’t use insulin the core temperature varies. This hormone is involved in the metabolic process that results in energy and heat production.

It isn’t yet clear why this happens. Scientists have discovered that there is a direct link. A link between insulin and core body temperature. The hormone being part of the organism’s internal “thermostat”.

In a healthy individual, the body increases its production of insulin when the core temperature needs to increase. Scientists have found that injecting this hormone into a certain area of the brain can cause the core body temperature to rise. Accelerating metabolism and activated brown adipose tissue. Brown fat prompts the body to burn white fat and produce energy and heat. So all these mechanisms work together in increasing the metabolic rate and core body temperature.


Also referred to as blood poisoning. Septicemia occurs when a bacterial infection affects the circulatory system. The infection can progress and can lead to sepsis. A life-threatening complication that manifests through inflammation blood clots. Impaired delivery of oxygen to tissues organ failure and in some cases death.

Septicemia can occur as a result of urinary tract infections lung infections or abdominal infections. The initial symptoms including chills and increased body temperature, increased heart rate and fast respiration.

As the condition progresses, red dots may appear on the skin. And the patient may experience confusion. The urine volume decreases and one may experience shock as a result of inadequate blood flow. Septicemia is a rare but very serious condition that can become life-threatening if treatment is delayed.

All these potential causes of altered body temperature can lead to severe complications, so if you experience the mentioned symptoms, make sure to schedule an appointment with your doctor.

    So when your body goes from hot 2 cold doesn’t always been that u have the flu.I myself do have type 2 diabetes militis.I have hi & lo blood spikes.Ii Really dont wish 2 die from either of the 2.So im thinkin n order 2 find out if i have anything like this Septicemia.The test would have 2 b sum sort of Thyroid test rite.Now this hot & cold feelings i was getting this mornin only lasted about a 1/2 an hr.Years ago.I guess about oh im not sure.So im gonna guess at r around 2002.I woke up with hot & cold flashes.But by the x i got dressed 4 work.Everything was fine.So its 2018 now.Like i said it only lasted 1/2 an hr.Same as the 1’st 1.And!

    I have the issue for bout 2 years. My feet are cold more than usual and I get real hot. I’ve been wondering about diabetes myself. Thank you for the information. Sometimes I have numbness in my first two fingers. Let me know if you have more information and suggestions as to what I should do.
