Drink water constantly
Water regulates body temperature, transports nutrients and oxygen, carries away waste, helps detoxify the kidneys and liver, dissolves vitamins and minerals, and cushions the body from injury. Even mild dehydration can lead to health problems, such as fatigue and constipation. There is also some evidence that drinking adequate water may help prevent some diseases such as kidney stones and may be associated with a lower incidence of colon cancer.
Water is best, but milk, juices, watery fruits and veggies, soups and decaffeinated tea can also count. But be aware that these other foods also add calories.
Don’t leave your water intake to chance. Develop a regular habit by keeping water bottles and pitchers near you as a reminder. And don’t wait until you’re thirsty. You may already be dehydrated. When in doubt, fill your glass again. You’ll need to drink extra amounts of water in dehydrating conditions such as hot, humid or cold weather, or high altitudes.
