Hot and humid weather, what are the signs that your body is dehydrated?

Some common signs of dehydration

Specialist Doctor 2 Huynh Tan Vu (Daytime Treatment Unit, University of Medicine and Pharmacy Hospital, Ho Chi Minh City - Facility 3) said that in hot and humid weather, the body will lose water due to excessive sweating. Dehydration will reduce blood volume, reduce blood flow through the kidneys, reduce urine excretion, cause metabolic disorders in cells, increase urea, increase products dissolved in blood.

Some common signs that your body is dehydrated include:

Thirsty, may feel very thirsty
Feeling dizzy or lightheaded
Heart palpitations
Little urine
Dry mouth
Urine is dark yellow and concentrated
Muscle weakness
Dry skin...

Trong thời tiết nắng nóng oi bức, cơ thể sẽ bị mất nước do ra nhiều mồ hôi, do đó cần bổ sung đủ nước — In hot and humid weather, the body will lose water due to sweating, so it is necessary to replenish enough water.

People who need to pay attention to water supplementation

In particular, the subjects that need special attention to water supplementation are:

People who do heavy work outdoors in the hot sun such as electricians, construction workers, workers...
Athletes who regularly train a lot
Poor eating habits in the elderly cause severe dehydration.
Using medications such as diuretics, laxatives, and ACE inhibitors to treat high blood pressure can cause more frequent urination or sweating, causing fluid imbalance.
People with fever and diarrhea: Patients often vomit and have loose stools, causing severe dehydration.
Kidney failure: Starting around age 50 and especially around age 70, the kidneys begin to lose some of their ability to remove toxins from the blood. Because the kidneys are less able to concentrate urine, water is excreted from the body more quickly as we age.

Things to keep in mind when adding water

Doctor Vu noted that you should not drink water that is too cold. Cold water not only causes digestive diseases and food safety problems, but also causes respiratory diseases such as sore throat, pneumonia, etc.

"Especially in hot weather, when you have just come back from the sun, you should limit drinking water that is too cold, because it causes the body to suddenly lose heat. In addition, it causes the capillaries and digestive tract mucosa to contract, slowing down the metabolism," Dr. Vu analyzed.

You should also not drink too much water at once. When the body feels thirsty due to the hot weather, people often quickly drink a full glass of water. However, this is a dangerous way to drink water for the body because drinking a lot of water in a short time makes the blood thin, increasing the burden on the heart. This is very dangerous for people who have just come back from jogging or doing heavy work...

At the same time, drinking a lot of water at once will cause continuous sweating, leading to the body lacking electrolytes such as potassium, sodium..., thereby increasing the feeling of thirst, not to mention causing bloating and possibly hiccups.

"You should drink slowly and in small sips so that your body can respond and gradually bring water to all organs, helping the body's absorption process to be smooth. You should not wait until you are thirsty to drink water and drink a lot. If you only drink water when you are thirsty or wait a long time to drink, you will quickly get tired," the doctor advised.
