Introduction to Low Body Temperature

Having a body temperature that is lower than normal isn't always a cause for concern; however, if it persists, it may indicate underlying health issues. Conditions such as hypothermia, nervous system disorders, and certain medications can lead to this situation. It's crucial to monitor the timing when measuring temperature and to take immediate action if symptoms like shivering appear. In children, cold skin can also be a warning sign.

Potential Causes of Low Body Temperature

A slight drop in body temperature isn't always alarming, as it can sometimes result from factors like fat loss or dry skin. Various elements, including age, gender, and the time of day, can influence body temperature. However, a significantly low temperature can be indicative of specific health issues. Let's explore these conditions, their symptoms, and preventive measures.


Hypothermia

Body temperature reflects the balance between heat produced and heat lost. Prolonged exposure to cold environments can lead to excessive heat loss, increasing the risk of hypothermia. Infants and the elderly are particularly vulnerable, as their bodies struggle to regulate temperature effectively. If someone experiences a dangerously low body temperature, consider the following actions:

Immediate Actions for Hypothermia

  • Move the person to a warmer environment immediately.
  • If clothing is wet, change it right away.
  • Wrap them in two or three blankets.
  • Provide warm beverages.
  • Avoid direct heat, such as hot baths.


Nervous System Disorders

The hypothalamus in the brain is responsible for regulating body temperature. When there are issues within the nervous system, it can disrupt the body's ability to respond to temperature changes. This can lead to a drop in body temperature. Disorders affecting the nervous system include:


Conditions Affecting the Nervous System

  • Stroke
  • Spinal cord injuries
  • Parkinson's disease
  • Multiple sclerosis


Impact of Certain Medications

Some medications used to treat depression, bipolar disorder, and schizophrenia can have side effects that lower body temperature.


Proper Temperature Measurement

If you're concerned about low body temperature, keep these tips in mind when measuring it:


Guidelines for Accurate Measurement

  • Avoid measuring temperature within an hour after exercising or taking a hot shower.
  • Do not measure temperature within 30 minutes of smoking.
  • Wait 30 minutes after consuming hot or cold beverages before taking a measurement.


When to Seek Immediate Help

  • Shivering
  • Confusion or slurred speech
  • Slow breathing
  • Weak pulse
  • Decreased concentration
  • Unconsciousness
  • In children, if the skin appears red and cold
