This patent application is accompanied by a priority claim based on Japanese Patent Application No. 2016-32302 filed on Feb. 23, 2016. The entire disclosure of this Japanese application is incorporated herein by reference. As part of the disclosure.

The present invention relates to a hydration agent that contains milk protein, sodium, carbohydrates, and stabilizers as active ingredients and is acidic.

Dehydration and heat stroke are likely to occur not only during exercise and work in hot weather, but also in daily indoor activities such as sleep, in a hot and humid environment. In particular, elderly people whose body fluids (the total amount of water in the body including water and electrolytes) are decreasing, and the amount of food important for water intake tends to decrease, and children who are susceptible to temperature (age 0-15) ), It is difficult to notice that dehydration is occurring, and gradually becoming dehydration, so-called heat stroke from hide dehydration is a serious problem.

In order to prevent heat stroke, it is necessary to efficiently release (dissipate) heat generated by exercise, work, daily activities, etc. to the outside of the body and adjust body temperature. This heat dissipation is accompanied by an increase in the blood flow rate of the skin for the purpose of heat dissipation due to heat conduction to the outside air and an increase in the amount of perspiration for the purpose of heat dissipation due to the evaporation of sweat. Therefore, for measures against heat stroke (prevention and alleviation), it is necessary to quickly replenish and retain water in the body.

Milk has excellent ability to retain ingested water, but casein, which is a component of milk, solidifies in the stomach, causing slower gastric emptying and slower water absorption into the body than water and sports drinks. There was a problem with.

On the other hand, sports drinks containing carbohydrates and electrolytes are often used for the purpose of replenishing carbohydrates consumed by exercise and electrolytes lost by sweating, and the effectiveness of hydration has been reported so far (for example, Non-Patent Documents 1 and 2). However, these sports drinks are not necessarily sufficient from the viewpoint of maintaining moisture in the body for a long time, and are reported to be inferior to milk (for example, see Non-Patent Document 3).

Oral Rehydration Solution (ORS) is a beverage developed to treat dehydration in cholera that causes diarrhea that loses a large amount of sodium. It is a beverage containing a lot of sodium and is often adjusted to be hypotonic (hypotonic solution) having a lower osmotic pressure than body fluid. However, oral rehydration designed for the treatment of pathological dehydration, such as vomiting and diarrhea, can be used in hydration in healthy people's exercise, work, and daily activities. In the long term, it may induce hypertension.
