Author Kim Jin-ho's Water and Health Stories (70) Why You Should Drink Water Before Feeling Thirsty as the Season Grows Colder

"Prevent winter dehydration through mineral-rich water intake"

As temperatures drop sharply and heating system usage increases, the season is upon us. Most people naturally drink water frequently due to thirst in summer, but water intake tends to decrease significantly in autumn and winter. However, dehydration is surprisingly considered one of the seasonal diseases that occurs more frequently in winter.

Indoor spaces in winter have low humidity and dry air due to heating. As a result, moisture is rapidly lost through the skin and respiratory system, but due to cold weather, people barely feel thirsty. When water intake decreases, blood viscosity increases and circulation becomes sluggish, which can lead to fatigue, headaches, constipation, and dry skin. For the elderly, the risk of cardiovascular disease also increases.

An internal medicine specialist in Seoul said, "In winter, thirst signals are weak, so many people fail to recognize that their bodies are dehydrated," and advised, "It is important to consistently consume 1.5 to 2 liters of water per day at regular intervals." Particularly if beverages containing caffeine such as coffee or green tea are consumed frequently, more moisture may actually be expelled, so the specialist emphasized the need for the habit of drinking "water itself."

Insufficient body hydration is directly linked to weakened immunity. When water is insufficient, mucous membranes become dry, making it easier for viruses to penetrate, and the function of waste elimination also deteriorates. Therefore, especially in winter when colds and flu are frequent, the habit of "drinking in advance before feeling thirsty" becomes the foundation of maintaining health.

Recently, health management that improves water quality rather than simply replenishing moisture has drawn attention. A representative example is the "mineral maker water bottle," a portable bottle-type product that allows easy generation of magnesium alkaline ionized water in daily life. This water has higher alkalinity than ordinary purified water and contains minerals such as magnesium, which can help relieve fatigue and reduce oxidative stress in the body.

Medical experts agree, "By consuming sufficient water and developing the habit of drinking good-quality water, it helps maintain balance in the body and promote smooth energy metabolism."

Health does not start from grand resolutions. The small habit of filling the beginning and end of the day with a sip of water protects immunity and vitality. As winter deepens, water becomes an even more "invisible health tonic."

This winter, a sip of water consumed before you feel thirsty will be the simplest and most effective measure to protect your health.
