In the winter, we tend to drink less water because we don’t sweat as much as we do in warm weather. But our body still releases humidity. It’s just not as obvious as it is in the summer. A good rule to calculate your water needs is half your bodyweight in ounces. The old rule, eight glasses of eight ounces daily, lacks any scientific basis, and if you think about it, it doesn’t make any sense either. It implies thatevery person, no matter their height, weight, or activity level, would need the same amount of water. So figure out how many glasses of water you should drink for your bodyweight. Take into consideration that your daily food and coffee and tea consumption count toward your water intake too. Fruits are usually high in water, and although coffee and tea are diuretics—it takes a lot of it to dehydrate a person—they contribute to your water intake. Drink up for good health, even if you don’t feel thirsty.
