Learn the science behind POCARI SWEAT and body hydration.

Water accounts for about 60% of our body weight.

If you weight 60 kg, your body will contain a whopping 36 kg of water.

It’s fair to say that “the human body is made of water.” The liquid in the body is called “bodily fluid.” About 4.6 billion years ago, the first life forms on Earth were born in the sea.

Over time, life evolved from sea to land, eventually resulting in the rise of human beings. This is the reason why the composition of our bodily fluid is similar to that of seawater containing ions (electrolytes). We could say that our body has its own “inland sea.”

People lose fluid from their body in all kinds of everyday activities.

We sweat not only when we play sports, but also when we take a hot bath, while we sleep, and while we travel to work or school, and even as we just sit in our office or school. Sweating plays an important role in all these situations, by keeping our temperature constant. When our body temperature rises, sweat is generated to cool the body. Cooling occurs because heat is absorbed from the surface of the body when the sweat evaporates. This cooling effect is similar to sprinkling water on a hot road in summer.

Thanks to our sweat, which keeps our body temperature constant in this way, our bodies are able to function normally and remain healthy.

In addition to freshwater, the fluids (liquids) in our bodies contain sodium and various other ions. This is why sweat is salty. Therefore, when the body sweats a lot, it loses sodium as well as water, disrupting the balance of ions in the body and making it impossible to live a healthy life.

POCARI SWEAT is a beverage that has an ion balance very close to that of bodily fluids. It allows you to smoothly replenish your body with the water, sodium, and other ions (electrolytes) you lose by sweating.

Even living very normally, we typically lose 2.5 l of water from our bodies each day, through urination, sweating, and respiration. Of this 2,500 ml, 1,500 ml is lost in urine, 100 ml in feces, and 900 ml through the skin and respiration. In contrast, our typical daily fluid intake from drinks and food is also 2.5 l. Like this the total volume of bodily fluids is maintained at a constant level. The sensation of thirst that we feel after sweating heavily is a part of the body’s mechanism for trying to restore lost fluid to the body.

By drinking only water we cannot recover properly from dehydration.

It is not possible to adequately restore lost bodily fluids just by drinking plain water. What is “spontaneous dehydration”?

Drinking only plain water to rehydrate the body may even be counterproductive in some cases.

If we continue to drink only water, excess water will be discharged from the body, as way of trying to keep the concentration of ions in the body fluid constant. For this reason, a phenomenon known as “spontaneous dehydration” occurs, in which the volume of bodily fluid cannot be adequately restored. In this situation, our brain causes our sense of thirst to disappear, to prevent us from diluting our bodily fluid further, even though our body has not recovered from dehydration. This can be dangerous, because we may be unaware of our lack of fluid.

Water is lost from the body before you notice it.

Even if you don’t notice it yourself, your body will become dry over time.

Even while we rest or sleep, our bodies lose fluid through the skin and by expiration. Since we cannot usually feel this release of moisture from the body, it is referred to as “insensible perspiration.” The amount of insensible respiration varies greatly with conditions, but it is estimated to be around 900 ml per day for a healthy person. Even when the body does not sweat, such as in an air-conditioned indoor space or on a dry winter day, we lose moisture from the body. So by the time we feel thirsty, the body is already quite dry.

When we play sport or work in sweltering hot weather, we sweat heavily.

When sweat is evaporated, it removes heat from the surface of the body, helping to lower the temperature of the body after it heats up. Temperature regulation is an important function of sweat. If you sweat a lot and lose a lot of body fluid, you won’t be able to lower your body temperature. It is a bit like car that overheats. If our body loses just 3% of its fluid, we experience symptoms like strong thirst, grogginess, and loss of appetite; if we lose 4 to 5% of our loss, dehydration occurs, with symptoms of fatigue, headache, and dizziness. A body fluid loss of 10% or more can result in death. Many years ago, people were commonly advised to avoid drinking water while exercising. Now that the importance of rehydration is better understood, however, active rehydration during sports is widely encouraged. Experiments have demonstrated that adequate rehydration helps to maintain exercise performance.

For effective hydration,  beverages with a salt concentration of 0.1 to 0.2% are recommended. This corresponds to 40 to 80 mg of sodium per 100 ml drink. POCARI SWEAT contains 49 mg of sodium per 100 ml.

In one experiment nine health adults were dehydrated by 4% of their body weight and then given water and POCARI SWEAT to drink in quantities equal to the volume of dehydration. When they drank only water, the quantity of blood plasma (a liquid blood component that indicates whether fluid has really entered the body), did not recover from dehydration. When they drank POCARI SWEAT they recovered from dehydration more quickly than when they drank water. This result demonstrates that POCARI SWEAT can smoothly replenish the body with the water and ions (electrolytes) that are lost by sweating.

The fluid lost from the body through sweating is not just plain water. It also contains ions (electrolytes) such as sodium and potassium. If we only drink water when we sweat heavily, the sensation of thirst will subside and the volume of urination will increase, even though the body has not recovered from dehydration, because the body reacts to prevent further dilution of body fluid. For this reason, when we sweat heavily it is good to drink POCARI SWEAT, because it has an ion balance close to that of body fluid. This benefit has been proven in a variety of studies and investigations.

On top of the fact that the bodies of young children have a higher proportion of water compared to adults, their temperature regulation function is also immature. This means that it takes little to disrupt the body fluid balance of a child. A baby in a stroller on a hot summer day is just a short distance from hot asphalt, in an environment that much hotter than we might imagine. Furthermore, a child wearing a hood to prevent sunburn will be exposed to even higher temperatures, resulting in even worse dehydration. It is also important to be careful when children are in child car seats. Children may not be able to complain of thirst on their own. And if they get absorbed in play they can easily forget about rehydration. Parents must be very careful to ensure that children are replenished frequently with water and ions (electrolytes).

Elderly people tend to have less fluid in their bodies than young people, because they generally have lower renal function and less muscle. (Muscle is a type of tissue that contains a large amount of fluid.) They are at a higher risk of suffering dehydration, because they find it more difficult to feel thirst and also because their temperature regulation function and resistance to heat deteriorates with age. In recent years, many cases of heat stroke have occurred indoors, so proper space temperature control and rehydration are essential for health management in the summer. It is necessary to actively rehydrate the body before feeling thirsty. Other risk factors for older people are the common tendency to restrict liquid intake to avoid going to the toilet too often, and fluid loss that occurs due to the side effects of medication for chronic illness. Regardless of the season, we should make it a daily habit to drink fluids frequently. POCARI SWEAT is an ideal beverage for minimizing the health risks of dehydration.

Let’s look at some everyday activities.

We constantly lose water and ions from our bodies, not just when doing sports, but in all kinds of casual everyday activities. The lost fluid and ions can be smoothly replenished with POCARI SWEAT. Here is an idea of how much fluid we lose in different activities.

Sitting  approx. 4 hours at approx. 23°C  approx. 200 ml

Commuting  approx. 1 hour at approx. 27°C  approx. 200 ml

Sleeping  approx. 8 hours at approx. 29°C  approx. 500 ml

Playing soccer  approx. 1.5 hours at approx. 26°C  approx. 200 ml
