What happens to the body when the heat is too hot?

The weather events of our country are increasingly unusual, heat waves are occurring on a large scale with the next year's temperature higher than the previous year. In this condition, we need to equip knowledge about heat-related diseases and preventions.

1. Heat-related diseases

Exposure for long periods of time and under extreme heat can cause heat-related conditions, such as heat exhaustion, heat cramps, and thermal shock (heat stroke). When our body works to cool itself in the harsh and prolonged heat, more blood flows to the surface of the skin and so the amount of blood pumped to the brain, muscles, and other bodies becomes less. This affects both health and the brain, and in some cases, this brings danger.

By reducing the time of exposure in high temperature environments and using other precautions, most heat-related symptoms can be prevented. People who work in high and humid temperatures – such as factories, bakery ovens, construction site throughout the summer – are most at risk. However, even the long-term heat of the afternoon at the beach brings problems if the warning signs are not given enough attention.

When treated quickly, most people fully recover from heat-insed diseases. However, thermal shock can lead to death if not properly controlled.

2. Causes of heat-in-disease

Heat-in-the-case pathology can happen to anyone. Chronic alcoholics, the elderly, children, obese people, and those with weak resistance are often at greater risk, including those who are taking certain medications such as antihistamines, antipychial drugs and tablets. High humidity also increases the risk of heat conditions because it affects sweating, the way the body cools itself. The causes of heat diseases can be divided into 2 main bodies:

  • Exhaustion due to exercising in the heat or heat stroke.
  • Inactived exertion but still suffered from heat shock.

Cases of heat exhaustion, heat cramps, thermal shock all occur when the body cannot effectively cool itself. But each case has small differences.

Heat exhaustion occurs when the body loses a large amount of water and salt through sweating and especially through hard work or practice. The loss of these necessary fluids disturbs the 3dular system that interferes with brain functions. Patients with heart, lung, kidney problems or who are on a Sodium diet may be particularly susceptible to heat exhaustion.

As well as heat exhaustion, heat cramps also occur when the body loses large amounts of fluids and salts. But heat cramps also occur with the loss of other nutrients such as Potassium and Magnesium, especially occurring during the exertion.

Thermal shock, which is the most serious heat pathology, occurs when the body tolerates exposure in long and intense heat and loses its ability to cool itself. In intense and prolonged hot temperatures, a normal part of the brain will harmonize the body temperature, and therefore the body will cool down. People with conditions that cause a decrease in the body's ability to regulate sweat – such as sclerosis or cystic fibroids may be at greater risk of heat shock.

3. Treatments for heat diseases

Heat cramps are usually mitigated by avoiding the heat: Rest, drink plenty of water, juices to ensure food hygiene, electrolynthical drinking water; and eat moderately salty dishes. Gently massage or squeeze hard into areas of muscles with cramps that can soothe contractions.

In severe cases, the patient should receive intravenous infusions with a solution containing salts. If heat cramps don't go away within an hour, or you have cardiovascular problems or are on a salty diet, seek medical help.

4. With heat exhaustion and thermal shock

First, call for urgent medical help, which is important. Then, if possible, give the patient water. But do not give if the patient is in a phlegmatic state or has passed out. Avoid alcohol or caffeine-containing beverages.

The basic treatment for heat exhaustion is epidemic and electrolycical compensation. Patients should be moved to a cool location, placed flat or slightly raised above their heads, and given little or less cool and slightly salty drinking water, such as electrolynthic drinking water, tomato juice, cold meat soup, or other vegetable and fruit juices.

Thermal shock usually occurs quickly and can cause permanent brain damage or even death if not treated in a timely manner. Anyone with heat shock needs urgent medical attention.

  • While paramedics are arriving, move patients into the shade or cover them with wet clothes or bed linen. Or you can take off your patient's clothes and sprinkle them with cool water until paramedics are present.
  • Ice packs can be placed in groin, neck, armpits or manually cooled, fan or cold-temperature-adjusted dryers (hot temperature dryers are not allowed).
  • If possible, use a thermometer to monitor the patient's temperature and stop cooling if their body temperature has returned to normal levels.
  • Once in the infirmary, patients who have suffered heat shock will be given intravenous infusions to correct dehydration and to provide adequate sodium, potassium. Patients may also receive intravenous medication to control seizures or other complications, monitored at the hospital bed within 24 hours to a few days.
