Hydration in chemistry

Hydration in chemistry is the replacement of water in the body, which maintains its composition. Water makes up about 60% of an adult’s body weight. Hydration can be done orally, dermally or intravenously.

Most of the water in our body is found in the intracellular space, from which metabolic functions are performed. Therefore, any change in the amount of water will seriously affect the health of the individual. As a rule, the intracellular space is the last to change in diseases that accompany disturbances in the volume of body fluids.

What are the symptoms of dehydration?

When we talk about hydration, it is important to stress that all living organisms are made up of water . This water does not appear in liquid and visible form, but it makes up muscles, bones and various interior tissues. Thus, faced with the loss of fluid from the body, the phenomenon of dehydration occurs. She has the following symptoms :

  • Cramps
  • Fatigue, bad mood or lack of attention
  • Increased heart rate
  • Vertigo and dizziness
  • Nausea and vomiting

What to do in case of dehydration?

Hydration is the only way to fight against dehydration and, at least, in the most common cases, it can be done simply by drinking liquid, water or fruit juice in particular. Today there are a wide variety of beverages specially created to allow the hydration of people who practice an activity physics . However, severe dehydration requires the absorption of different nutrients intravenously.

Proper hydration allows the body to function much better, as water acts as a nutrient to generate the energy needed by our body. Hydration of two to three liters of fluid per day is considered one of the best methods that work together for weight loss and cleansing the body.


Meaesurement of hydration by radio waves:

The technique would consist of using a device that looks like a wristwatch, thus providing a convenient and painless alternative to existing, more invasive methods.

It is normal, during intense physical activity, to lose between 2 and 4% of your total body weight, due to dehydration caused by sweating . Severe dehydration however, corresponding to an 8% loss of body weight, can be fatal.

 Measuring hydration level is important for categories such as athletes, the elderly and malnourished children.

Existing methods requiring blood collection, while being accurate, may not be feasible in an emergency. 

Other methods, such as measuring the body’s electromagnetic impedance, are not sufficiently precise.

Yair Shapiro and his colleagues at the Heller Institute of Medicine (Tel Hashomer, Israel) observed how radio waves of various frequencies were absorbed by subjects subjected to exercise sessions. To do this, they placed on the wrists of the subjects who had taken part in the experiments, a small device absorbing radiofrequencies.

They then observed a definite correlation between weight loss and absorption of radio waves. The researchers plan to conduct observations on other groups, in order to verify these results.
