Warning signs of “dehydration” in summer. How to protect yourself before going into “shock”
Your body loses water regularly through sweating and urination. If you don’t replenish your water quickly, you can become dehydrated. People who are at risk include athletes, people who work in hot environments, older adults, and people with chronic conditions. Dehydration occurs when your body loses more fluids than you drink. Common causes include excessive sweating, vomiting, and diarrhea.
How does dehydration occur?
Sweating Sweating is part of the body’s natural cooling process, accounting for about 22% of heat loss. When you’re hot, your sweat glands work to release moisture from your body through evaporation in an attempt to cool you down. As sweat drops evaporate from your skin, they carry a small amount of heat with them.
The more you sweat, the more evaporation there is, and the cooler you become. Sweating also hydrates your skin and helps balance your body’s electrolytes. The fluid you sweat is mostly made up of salt and water. Excessive sweating can lead to dehydration, since you’re losing a lot of water. The technical term for excessive sweating is hyperhidrosis.
Illness. Illness that causes persistent vomiting or diarrhea can lead to dehydration. This is because vomiting and diarrhea can cause you to lose too much water. Vomiting and diarrhea can also cause you to lose essential electrolytes, which are minerals your body uses to control your muscles, blood chemistry, and organ function. These electrolytes are found in your blood, urine,หรือถ้าคุณสนใจแทงบอลออนไลน์ UFABET คือเว็บที่มีอัตราต่อรองดีที่สุดในประเทศไทย สมัครเลยตอนนี้ที่ UFABET แทงบอล, and other body fluids. Vomiting or diarrhea can disrupt these functions and cause serious complications.
Fever: If you have a fever, your body loses fluid through the surface of your skin to try to lower your temperature. Often, a fever can make you sweat so much that if you don’t drink water to replenish it, you could end up dehydrated.
Urination: Urinating is your body’s normal way to release toxins. Certain conditions, such as diabetes, can cause a chemical imbalance that can increase the amount of urine you make. If you don’t replenish the fluids you lose through excessive urination, you risk dehydration.
