Heat illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion.It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke. [1]
Paroxysmal nocturnal dyspnea or paroxysmal nocturnal dyspnoea (PND) is an attack of severe shortness of breath and coughing that generally occurs at night. [1] It usually awakens the person from sleep, and may be quite frightening. [ 2 ]
Heat exhaustion is a heat-related illness characterized by the body's inability to effectively cool itself, typically occurring in high ambient temperatures or during intense physical exertion. In heat exhaustion, core body temperature ranges from 37 °C to 40 °C (98.6 °F to 104 °F).
Essentially, dehydration may lead to hyperthermia because overheating can alter your body’s normal temperature. (See more about your body's response to heat and what happens when you sweat here.) 5.
This takes a toll over time, so that despite feeling like you are getting adequate rest, you are still chronically tired. 5. Trouble sleeping — Despite the fatigue, you may be suffering from ...
As can be seen, hyperthermia can be considered an increase above the thermoregulatory set-point. Hypothermia: Characterized in the center: Normal body temperature is shown in green, while hypothermic temperature is shown in blue. As can be seen, hypothermia can be conceptualized as a decrease below the thermoregulatory set-point.
Onset of symptoms: Here, you start experiencing the first signs of a cold, such as a sore throat, sneezing, and mild fatigue. This stage marks the body’s initial immune response to the infection.
Heat stroke is a clinical diagnosis, based on signs and symptoms. It is diagnosed based on an elevated core body temperature (usually above 40 degrees Celsius), a history of heat exposure or physical exertion, and neurologic dysfunction. [ 5 ]
