Understanding Hypothermia
Hypothermia occurs when the body’s internal thermostat, known as the hypothalamus, fails to regulate body temperature effectively, resulting in dangerously low body temperatures. Medical professionals typically diagnose hypothermia when a person’s temperature falls below 95°F or 35°C. Several factors can contribute to the onset of hypothermia, including exposure to freezing temperatures outdoors, residing in a poorly heated environment, or submersion in cold water, such as accidentally falling into a frozen pond. The progressive cooling of the body triggers a cascade of physiological responses, causing symptoms such as shivering, slurred speech, shallow breathing, a weak pulse, confusion, drowsiness, memory loss, and impaired coordination.
Understanding Fever
Fever is a natural response by the body, indicating an underlying problem such as a viral or bacterial infection or illness. It is important to note that fevers typically subside on their own. However, there are various factors that can trigger a fever, including certain medications like antibiotics and blood pressure medications. Additionally, medical conditions such as heat exhaustion, arthritis, heart attack, hyperthyroidism, and arthritis can also lead to a fever.
During a fever, the hypothalamus, which is responsible for regulating body temperature, does not adjust the temperature. Instead, the immune system raises the internal temperature in an effort to combat and eliminate foreign substances. Generally, a temperature of 100.4°F (38°C) (101°F if taken rectally) is considered indicative of a fever.
If a fever persists for more than a day or worsens, it is advisable to seek medical attention from a doctor.
