Caffeine

Caffeine is a natural substance found in dozens of plants, including coffee beans. People prefer to use caffeine, because it starts the central nervous system of the body.

This jump makes you feel more attentive and ready to take on everything from the interrogation of children to the presentation of the case in court. For this reason, some people call caffeine their “elixir of life.”

There are many unpleasant side effects from too much caffeine: insomnia, high blood pressure, anxiety, and addiction, to name a few. One of the side effects of consuming more than 400 mg of caffeine per day can also be dehydration, because coffee is a diuretic.

Is coffee a diuretic?

Diuretic substance is that which increases the need for urination. Naturally, water is a diuretic, along with coffee and any other caffeinated beverages, such as soda.

Studies (conducted back in 1928 and again in 2005) show that caffeine is a weak diuretic. The human body will adapt to regular caffeine in 4–5 days and you will no longer urinate excessively.

This means that regular use of caffeine does not lead to chronic dehydration. At first, coffee may be a diuretic, but these effects quickly disappear.

Lawrence Armstrong, a professor of kinesiology at the University of Connecticut and director of the Human Activities Laboratory, said that if you drink more fluids of any kind, the amount of urine you produce will increase. “If you drink a liter of water, [urination] will increase … and this does not mean that you should not drink water.”

A study in 1928 tested three people whose urine was compared before and after caffeine. After two months without caffeine, subjects received half a milligram of caffeine. The amount of urine produced was “noticeable” after they got caffeine.

With regular caffeine intake, patients had less noticeable loss of urine after 4-5 days. Armstrong and several other researchers conducted an updated study in 2005. A wider range of subjects participated in this study during the 11-day period, and confirmed the results of the 1928 study.

Reducing caffeine intake can hurt more than help

does coffee dehydrate you

Some people feel the need to reduce the amount of caffeine they drink. A commitment to limit caffeine intake forever; reducing coffee consumption over a short period of time can lead to dehydration. As mentioned earlier, your body adjusts to caffeine in a few days.

If you reduce the amount of caffeine you drink over a short period of time, your body will have to begin the process of adapting to caffeine-related habits when you start to drink more.

Bouncing between the amounts of caffeine you take is more harmful than regular daily or even weekly amounts.

Dehydration? Do not drink coffee

If you feel dehydrated, do not use caffeine for rehydration. Drinking coffee or caffeinated soda may seem like a tempting decision, as lack of fluid causes fatigue. But experts recommend avoiding caffeinated beverages while trying to recover from dehydration.

Does Coffee dehydrate you? 7 myths about hydration and water consumption

Each cell in the human body needs water to function normally, from maintaining body temperature to cushioning and protecting joints and organs, and aiding digestion.

That’s why the site HuffingtonPost listed the 7 most common myths about dehydration. Check out:

1) Myth: Dehydration is uncomfortable but not dangerous

Truth: Although most people experience only a few symptoms of dehydration, such as a headache, sluggishness, and decreased urination, you need to be aware that you may need medical attention on occasion. Complications such as cerebral edema, seizures, kidney failure and even death can happen. When the situation is observed early, when there is a lot of thirst, dizziness, confusion, and decreased urine, adults can be treated with some isotonic drink. However, in children and the elderly, attention should be increased when they have diarrhea, vomiting, fever, irritability and confusion.

 

2) Myth: If you are thirsty, it is because you are already dehydrated

Truth: Thirst is the body’s way of saying that one needs to drink water. Remember that you are not dehydrated the moment you feel dry mouth. “When you get thirsty, the water deficit in the body is trivial. It should be only 1% reduction in the whole water level and can be recovered with some fluid intake,” explains Dr. Stanley Goldfarb, professor at the University of Pennsylvania. In fact, drinking water when you are thirsty seems basic and is a surefire method to prevent dehydration. According to Dr. Timothy Noakes, a professor at the University Of Cape Town, South Africa, only humans do not follow this “instinct”. “You don’t tell your dog or cat when they should drink water, because they have a thirst mechanism.

3) Myth: You need to drink eight glasses of water a day.

Truth: This number is out of date and is spread today by water companies. The England Institute of Medicine recommends that men drink three liters of fluid a day while women drink 2.2 liters. However, there are experts who say that there is no exact number and that you should not drink any fluid unless you are thirsty. It is also worth remembering that not only water counts, but juice, coffee, tea and even food must also be accounted for. According to the Institute of Medicine, 20% of the rate of fluid consumed per day comes from food, especially fruits and vegetables such as melon and cucumber.

4) Myth: Light-colored urine is a sign of good hydration

Truth: While not very pleasant, looking at the color of urine can say yes if you have hydration on time. However, the color you should look for is not the lightest but a pale yellow, according to Lawrence Armstrong, a professor at the University of Connecticut. Also be aware as some supplements and even foods can change the color of urine.

5) Myth: Liquid never hurts

Truth: Excessive hydration can be very dangerous and very rare as well. Drinking fluid excessively causes a phenomenon called hyponatremia, which is when the body’s sodium level gets so low that cells begin to swell. Symptoms are usually headache, vomiting, nausea, fatigue and can lead to coma. However, there is no cause for concern. According to experts, athletes and marathon runners are the most common to be hospitalized with this problem. “People only have a problem when they drink beyond their thirst and this is due to lack of information or influence from sports commercials,” says Noakes. One of the secrets may be to never drink so much water that you feel too full.

6) Myth: Athletes Need Special Drinks

Truth: A person who has been exercising for less than an hour does not have to worry about their body’s water level, as no one will deplete their electrolyte and glycogen stores unless they are exercising intensively for over 60 minutes. Athletes can benefit from the sugar and sodium contained in isotonic, however, they have so many components that may not be needed. Instead of using them, always try to make your own drink or bet on foods that have carbohydrate and sodium. According to experts, these drinks are sometimes unnecessary, because usually the daily diet already has these nutrients.

7) Myth: Coffee Dehydrates

Truth: Coffee is dehydrating only if a person overdoses on it. While caffeine has dehydrating effects, the water it has in coffee or tea is more than enough to maintain body water levels.
