Drink eight glasses of water a day! We have all heard that advice time and time again. Hydration is part of what helps your body function properly.
But if you don’t drink enough, you can become dehydrated. Dehydration can cause many issues, including headaches, dizziness, fatigue, fainting, rapid heartbeat, and other symptoms.
So how do you know if you become dehydrated? It’s all in the color. Review this infographic for helpful color cues so you can avoid becoming dehydrated.
What is dehydration?
Dehydration is the result of losing or using more fluid than you take in. Without sufficient fluids, your dehydrated body will soon be unable to carry out normal functions.
Dehydration can occur to anyone who fails to drink enough water. This is especially the case during hot weather, especially when engaging in vigorous activity.
Dehydration can lead to serious complications, ranging in severity from heat cramps to heat exhaustion or potentially life-threatening heat stroke.
The risk of heat-induced illness increases when working or exercising outside in hot, humid weather.
We sweat more in hot weather and lose fluid. Anywhere from 100 millilitres to several litres per day, depending on our activity levels and the temperature.
In hot climates, people working or exercising lose the most fluid, sweating as much as 2.5 litres an hour. Losing fluid in this manner can โปรโมชั่นพิเศษจาก UFABET สมัครตอนนี้ รับโบนัสทันที easily lead to mild dehydration, causing headaches, irritability and diminished powers of concentration. Between 50–80 per cent of your lean body mass is water.
Sweat evaporates from your skin and takes some of the heat with it.
The more you sweat, the more evaporation, the more you are cooled off. Sweat is mainly salt and water. It will not evaporate effectively when the air is humid.
Excessive sweating (hyperhidrosis), with no replenishment of fluids, will lead to increased body temperature, a need for more fluids, and dehydration. Which can lead to more complications.
The two age groups most vulnerable to the risk of dehydration are older adults and young children, for whom the condition is especially dangerous. Younger children are unable to get a drink for themselves or tell you when they’re thirsty. The most common causes of dehydration in children include diarrhoea, vomiting, and fever.
