1 . By now we all know the importance of drinking enough water throughout the day, but there is such a thing as too much. Earlier this summer, a 35-year-old Indiana woman, died from water toxicity (毒性作用) after drinking too much water in a short period of time, according to a local news report.
While drinking enough water is important, overdoing it can lead to low levels of sodium (钠) in the blood, which can be life-threatening, according to Julia Zumpano, an expert at Cleveland Clinic’s Center for Human Nutrition.
Exactly how much is enough for our body depends on a variety of factors, including our weight, age, location and overall health. People in poor health, or active people such as athletes, are at risk of water toxicity, as they tend to drink large amounts of water and lose sodium through their sweat. So are women and children because of their smaller body size.
While the gold standard for many years has been eight glasses of 8 ounces (盎司) of water per day, the National Academy of Medicine suggests enough water intake is about 125 ounces for men and about 91 ounces for women. And it recommends not drinking more than 48 ounces of water per hour. This includes total water from fruits, vegetables and other drinks besides water.
If you struggle with getting enough water per day, you can try water bottles to help track your water intake. Eating fruits and vegetables can also increase our water intake. You could experiment with adding flavor to improve the taste of your water.
“Most people had better keep drinking water throughout the day, but larger amounts may be needed in the heat for an extended period of time or during exercise. If you are thirsty for water — listen to your body. But don’t overdo it,” says Zumpano.
