- Dehydration.
Everyone knows how important it is to drink water throughout the day. However, not everyone follows the recommendations for maintaining water balance. As a result, most people are in a state of mild dehydration almost all the time. In hot weather, the risk of dehydration increases sharply. Through sweating, we lose more fluids, along with electrolytes (salts of potassium, calcium and magnesium). When the electrolyte balance is disrupted, the body exerts additional effort to maintain the normal internal processes. Additionally, due to the loss of fluid, the blood becomes thicker and the heart has to work harder to pump it through the vessels. The body expends more energy and that drains its energies.
- Increased body temperature.
Air temperature, heart rate, and even metabolic rate, all these affect body temperature. When you sunbathe, your body temperature rises. The body reacts to overheating by trying to slow down the rise in temperature. Sweat glands start working harder, and breathing, and heart rate increase. All of this depletes energy reserves, and we experience a breakdown.
As a result, it affects the decline the clarity of thought and productivity throughout the day. To enhance brain activity and remain productive during the workday, it is recommended to taking Armod and Modavigil. Studies have shown that individuals taking modafinil and armodafinil experience reduced drowsiness and improved clarity of thought.
- Decreased blood pressure.
Among internal organs, the brain suffers the most from overheating. Thus, in hot weather, blood flows to the head to cool the gray matter. This is why the face may become red. The volume of blood that nourishes other organs decreases, blood circulation slows and blood pressure drops. All the body’s systems enter energy-saving mode.
- Recovery after excessive sun exposure.
Ultraviolet rays damage skin cells, can cause sunburns and wrinkles and negatively affect the lens and retina of the eyes. The more time you spend in the sun, the more work your body has to do to recover. For example, in the case of sunburn, more fluid is directed to the damaged area. However, in this case, the body has less water for sweating, that reduces the body’s ability to cool itself. Consequently, we feel fatigued and drowsiness.
Sweating helps maintain a constant body temperature and prevents overheating. By sweating, the body expends energy to break molecular bonds in the liquid (sweat), causing it to transition from liquid to gas. This energy expenditure lowers body temperature. Therefore, the hotter the weather is, the more we sweat and the more exhausted we become.
The body’s ability to regulate temperature is not limitless. If the sun’s “load” is excessive, the body overheats. This leads to heat exhaustion, characterized by excessive loss of moisture and electrolytes due to severe overheating. Symptoms include headache, dizziness, low blood pressure, nausea, rapid or slow pulse, sticky sweat, intense thirst, high temperature, drowsiness and fainting.
In cases of heat exhaustion, it is important to move the person in a cool place, help him to lie down and provide fluids and fresh air. Reducing body temperature can be aided by wiping with a damp cloth or bathing in warm water. Typically, 30 minutes is enough to restore normal well-being. If, after 30 minutes of rest in a cool place, the body temperature continues to rise or the person faints, it is necessary to call emergency services.
