On a hot journey, bottled mineral water, purified water, and the like are often "treasures" that tourists carry with them. Although they can quench thirst, excessive consumption can lead to excessive loss of body salt, causing mild "water intoxication".
According to experts, people often think that "water intoxication" only occurs in accidental drowning incidents, but it also happens in daily life, albeit to a lesser extent and often unnoticed. Especially during summer travel, people tend to get so caught up in their activities that they sweat profusely, leading to a high probability of losing electrolytes like sodium and salt. If at this time large amounts of fresh water are consumed without replenishing salt, the water absorbed by the gastrointestinal tract is then excreted through sweat, exacerbating the loss of salt. When the salt in the blood drops to a certain level, people will experience common symptoms of mild "water intoxication," such as dizziness, vomiting, fatigue, and muscle pain in the arms and legs.
Experts remind that to avoid "water intoxication" during summer travel, it is essential to master proper drinking techniques.
First, drink an appropriate amount of light salt water. Drinking some light salt water during the journey can replenish the inorganic salts lost through excessive sweating. The most convenient method is to add 1 gram of salt to 500 milliliters of drinking water and consume it in a timely manner. This not only replenishes the body's needs but also prevents electrolyte imbalance.
Second, drink frequently but in small amounts. Many people are accustomed to deciding whether to drink water based on thirst, but this is not scientific. Thirst is an important signal that the body's water balance has been disrupted. During a journey, one should not drink large amounts of water at once when thirsty. Instead, it should be consumed in small amounts over multiple times to facilitate absorption. A reasonable approach is to drink 100 to 150 milliliters each time, with a half-hour interval.
Third, try to avoid drinking water that is too cold. During physical activity in summer travel, the body's temperature is usually high, and drinking large amounts of cold beverages can easily cause digestive system problems. Experts suggest that travelers should avoid drinks below 5 degrees Celsius. It is more scientific to drink light salt water at around 10 degrees Celsius. This way, the goal of cooling down and quenching thirst can be achieved without harming the digestive system, while also replenishing the body's needed salt in a timely manner.
