On the 22nd, the YouTube channel 'Kang Suji TV Living, Loving, Acting' posted a video titled 'Everyone, if you go near Baekun Lake, be sure to try this place!' In the video, Kang Suji visited a squid restaurant. While waiting for her ordered food, Kang Suji took a tumbler out of her bag. The PD asked what she carried in the tumbler, and Kang Suji replied, "It's water." She then added, "Some people also carry various teas or sungnyung (scorched rice drink) in theirs." Kang Suji has previously revealed that she often carries warm water in her tumbler for health reasons. She said, "When I had COVID-19 or sinusitis, drinking warm water from my tumbler helped me feel better."

Developing a habit of drinking enough water every day, like Suzy Kang, is good for health. Drinking sufficient water boosts metabolism and helps eliminate waste products from the body. The feeling of fullness caused by drinking water also reduces calorie intake, which aids in dieting. According to a thesis by Dr. Brenda Davis from the Department of Nutrition at Virginia Tech in the United States, people who drank two cups of water 20 minutes before a meal lost about 2 kg more than those who did not. When suffering from kidney stones, drinking plenty of water increases urine volume, naturally helping to pass the stones, and dilutes the urine, making it effective in preventing stones. Especially when experiencing fever or diarrhea caused by enteritis, dehydration symptoms can easily occur, so it is necessary to consume more fluids than the recommended amount.

According to the Ministry of Food and Drug Safety, the recommended daily water intake is 2,600 mL for men and 2,100 mL for women, which is about 6 to 8 cups per day. Drinking water at ▲on an empty stomach in the morning ▲before and after meals ▲before going to bed can help meet the daily recommended amount. Since no fluids are consumed during sleep, the body's hydration level can decrease, making the blood thicker. However, for those who experience nocturia, it is advisable to refrain from drinking fluids before sleep. When drinking water, it is better to sip lukewarm water gradually rather than gulping down cold water.

Meanwhile, excessive fluid intake can be harmful in cases of certain diseases. The most common examples are hypothyroidism and renal failure. When thyroid function is decreased, fluid excretion is impaired, and drinking a lot of water can lead to hyponatremia, a condition where sodium levels in the blood drop. Patients with hypothyroidism should limit their fluid intake to less than 1 liter per day. Similarly, patients with renal failure should avoid drinking more than 2 liters of water per day due to impaired fluid excretion, and if they are undergoing dialysis, about 3 to 5 cups (1 cup = 200 mL) is appropriate.
