Coldness Symptoms

Coldness is the condition of being at a low temperature. Normal body temperature is around 98.6 F (37 C), and the human body has various mechanisms in place that regulate this body temperature and prevent the body from becoming too cold or too hot.

There are various environmental situations that challenge the body's regulatory mechanisms against cold – for example, wintertime or even an excessively air-conditioned room. Feeling cold in such situations is a normal response that, most times, the body can easily resolve. However, there are some situations in which your body is unable to mount a response and bring your body temperature back to normal. When your body begins to lose heat faster than it can produce it, you will begin to feel symptoms of coldness that do not easily resolve. If your body temperature falls below 95 F (35 C) this is a condition known as hypothermia.

Depending on how long your body remains at this low temperature, in addition to a generalized sensation of coldness, you may also experience:

Hypothermia can be extremely dangerous. At very low temperatures, your organs cannot work properly, and if left untreated hypothermia can lead to complete heart and respiratory failure and ultimately death.

Call 911 immediately if you notice any symptoms, especially excessive shivering. Once you develop symptoms of confusion and fatigue, you may find it difficult to think clearly and get the appropriate care.

Coldness Causes Overview

Most causes of coldness are related to environmental triggers such as exposure to cold weather or water, but there are many medical conditions that either disrupt the body's natural mechanisms or put the body at risk for losing heat when exposed to cold situations.

Environmental causes

  • Cold weather or water: Cold weather is an obvious cause, but many people often underestimate how such conditions can affect the body. Water that can cause such coldness symptoms does not necessarily need to feel extremely cold; any water that is less than normal body temperature can cause rapid heat loss. Most people cannot willingly stand such temperatures for prolonged periods of time and will quickly get out of the water. But for those who fall off of a boat or find themselves stranded in a large body of water, quick escape is often not an option.
  • Inappropriate attire: Wearing clothes that aren't warm enough for weather or water conditions can easily cause coldness symptoms. Conversely, being unable to remove wet clothes promptly and change into warm clothes can cause coldness and its associated symptoms as well.
  • Inappropriate living conditions: Houses that are improperly heated, especially during wintertime, can cause these coldness symptoms in at risk populations such as infants and the elderly.

Systemic symptoms

  • Central: The brain is the central control center for body temperature. Central causes of coldness result from dysregulation in these brain processes. For example, disorders of the hypothalamus can cause coldness because the body cannot mount proper responses.

  • Metabolic: The body relies on metabolic processes to maintain proper body temperature. Disruption in process that make synthesize important metabolic hormones such as insulin and thyroid hormone can cause coldness symptoms.

  • Fat synthesis: Fat is necessary to maintain the heat your body creates. Any condition that significantly decreases your body fat can lead to feelings of coldness because your body has no means of maintaining the heat it creates.

Top 4 Coldness Causes

  1. 1.Diabetic Hypoglycemia

    Hypoglycemia (severely low blood sugar) can occur in Type 1 (more common) and Type 2 Diabetes. It is usually caused by poorly timed use of blood-sugar-controlling medication.

    Severely low blood sugar is extremely dangerous. You need to go to the ER immediately, where blood tests to assess your blood sugar will be done quickly and stabilized immediately if found to be low.

    Top Symptoms:
    fatigue, irritability, anxiety, racing heart beat, dizziness
    Symptoms that always occur with diabetic hypoglycemia:
    being severely ill
    Hospital emergency room
  2. 2.Hypothyroidism

    Hypothyroidism occurs when the thyroid, a butterfly-shaped organ inside the neck, no longer produces adequate levels of hormones. Thyroid hormones are essential for many bodily functions including breathing, heart rate, and metabolism.

    You should visit your primary care physician. Hypothyroidism is a complex condition that is usually treated with hormone replacement therapy.

    Top Symptoms:
    fatigue, depressed mood, difficulty concentrating, weight gain, muscle aches

  3. 3.Mild Hypothermia

    Hypothermia is defined as a body core temperature lower than 95 degrees Fahrenheit or 35 degrees Celcius.

    It is imperative to prevent further heat being lost. If possible, move the person indoors or somewhere warm immediately. Remove wet clothes and wrap the person in warm blankets or clothes.

    Top Symptoms:
    coldness, fatigue, pale skin, turning blue or purple from coldness
    Hospital emergency room
  4. 4.Moderate to Severe Hypothermia

    With prolonged exposure to freezing cold, the body can lose the ability to maintain a safe core temperature. If this continues for long enough, you can become confused or even lose consciousness

    Call an ambulance immediately. Get to a warm place. You should be lying down with very little movement. Remove any wet clothing, if possible, and cover up with heavy blankets or jackets.

    Top Symptoms:
    coldness, pale skin, slow heartrate (under 60bpm), alertness level change
    Symptoms that never occur with moderate to severe hypothermia:

Coldness Treatments and Relief

There are many preventative methods you can utilize to prevent low body temperature.

Developed by the Mayo Clinic, the acronym COLD– cover, overexertion, layers, dry – is an excellent way to remember the different methods you can use to protect yourself and family from this potentially life-threatening condition

  • Cover: Wear a hat or other protective clothing to prevent body heat from escaping the head, face and neck. Use mittens instead of gloves to cover your hands.
  • Overexertion: In cold weather, avoid activities like running or jumping that cause sweating. The combination of wet clothing and cold weather can cause your body to lose heat more quickly.
  • Layers: Wear loose-fitting, lightweight clothing in layers. Outer clothing made of tightly woven, water-repellent material is best for wind protection. For inner layers, choose materials such as wool, silk or polypropylene – these materials hold body heat better than cotton does.
  • Dry: Get out of wet clothing as soon as possible and try to stay as dry as possible. Pay special attention to your hands and feet, as these body parts can easily get wet again.

Unfortunately, there is no acronym for cold-water situations, but the reasoning remains the same. Stay as warm as possible and minimize heat loss. Wear life jackets, do not remove clothing, huddle with others, and try to move as little as possible – i.e. do not attempt to swim to safety unless you are close to land, or you will expend unnecessary energy and body heat.

However, if you do experience such symptoms, call 911 immediately.

While waiting for medical attention:

  • Move from the cold
  • Cover yourself or the affected person with blankets
  • Remove wet clothing
  • Drink warm beverages that are non-caffeinated and nonalcoholic

But do NOT apply direct heat. Methods such as heating pads or hot water can damage the skin or, more importantly, cause irregular heart rhythms that can cause the heart to stop.

Medical treatment for coldness caused by environmental factors includes rewarming processes:

  • Passive: Passive methods for rewarming include strategies such as blankets and warm fluids.
  • Blood: More aggressive methods include warm IV fluids and hemodialysis – a process that can be used to allow warm blood to be re-circulated in the body.
  • Airway: Warmed oxygen via mask or nasal tube can warm the airways and help raise body temperature.

Medical treatment for more systemic causes of coldness includes:

  • Hormone replacement: Hormones are key players in the regulation of body temperature. If your cold symptoms are due to hormone imbalance your doctor will prescribe the appropriate hormone(s) to get your body back on track.
