Many people refresh themselves by drinking coffee, but others get more and more tired. Experts warn that restlessness and tiredness may be a warning to the body. If you blindly drink caffeinated and diuretic drinks, you may put the body in a dehydration crisis!.

When the body shows the following six major symptoms, it represents a lack of water in the body:

1. Dry mouth: dehydration in the body and reduced saliva secretion can lead to dry mouth.

two。 Restless: when the body is short of water, breathing and heartbeat will accelerate, which can easily lead to emotional anxiety.

3. Lack of concentration: when the brain is short of water, it can affect thinking, making it difficult to concentrate.

4. Fatigue and burnout: under the condition of lack of water, it will cause the gray nerve tissue in the brain and spine to contract, resulting in fatigue and burnout.

5. Urine yellowing: when the body is short of water, the concentration of sodium in the blood will also become higher, and the kidneys will recover water from the body and reduce urine volume to maintain the body's initial electrolyte balance.

6. Dry and itchy skin: lack of water in the stratum corneum of the skin, it is easy to dry and itch.

Dietitians suggest that once the above symptoms are found, small mouthfuls should be taken to replenish water, and normal adults should drink 2000 milliliters of water a day, but drinks such as coffee, tea, cola and alcohol contain diuretic caffeine ingredients. Drinking too much not only can not effectively replenish water, but also accelerate the loss of a large amount of water in the body, so it is not suitable to be used as a source of water supply.
