Exposure to periods of high temperatures can pose a threat to your health. Learn about some of the most common problems.

  • Heat cramps: These muscle pains and spasms caused by heavy exertion are considered an early symptom that the body may be experiencing heatstroke due to the loss of salt and electrolytes.
  • Heat exhaustion: Due to the loss of body fluids from sweating, this generally occurs when doing intense exercise or when working in a hot and humid environment. Due to the loss of fluids and electrolytes and a compromised central nervous system, different symptoms may occur such as intense thirst, headaches, dizziness, fatigue, irritability, high blood pressure, tachycardia and hyperventilation.
  • Heatstroke: This occurs when the system that controls a person’s body temperature, producing sweat to cool the body, stops functioning. If not treated on time, this condition can cause brain damage.
  • Syncope (fainting): This symptom indicates that there is an insufficient flow of blood, oxygen or glucose to the brain. Patients describe syncope as a fainting sensation, blurry vision and having postural tremors. Its recovery time is fast. As soon as the person lies in a horizontal position, their system will return to normal.

Some tips to help prevent further damage from excessive exposure to heat include increasing your intake of liquids before becoming thirsty in order to stay well hydrated, and drinking oral rehydration solutions.
