Drinking plenty of water can help keep your body functioning at its highest capacity. Staying hydrated can help you to:
Improve physical performance. During physical activity, our bodies use up a lot of water. So, staying hydrated before, during and after exercise helps to protect your body from harm and perform better. Proper hydration can reduce fatigue, improve endurance, lower your maximum heart rate and more. It can also help you to be less sore after exercise.
Help you to lose weight. Are you having trouble with your weight loss efforts? Increasing your water intake may help you achieve better results. Studies show that people who are on diets lose more weight when they also increase their water intake. In one study, people on weight loss diets who drank 500 milliliters of water before each of their three daily meals for 12 weeks lost 4.6 more pounds on average than people who did not drink the additional water.
Boost your mood. People who drink more water also tend to have better moods. One study found that when people who regularly drank less than 1.2 liters of water per day increased their intake to 2.5 liters per day, the participants experienced significantly less confusion, bewilderment, fatigue and sleepiness. On the other hand, for people who regularly drank two to four liters of water per day who were then restricted to one liter per day, the reduced water intake led to negative effects on mood, including decreased contentedness, calmness and positive emotions.
Boost your brainpower. Several studies have shown that people drinking water during cognitive tasks performed much better than people who did not drink water during the tasks. These results have been found in both adults and children. Studies suggest that even mild dehydration can impair cognitive function in the short term.
Prevent headaches. Water deprivation is a very common cause of headache. In most cases, rehydrating can provide relief from a headache. For some people, dehydration can also trigger a migraine, so be sure to keep your water intake regular if you are prone to getting migraines or headaches.
Protect against disease. Proper hydration may be a useful tool in preventing a variety of health conditions and diseases. Staying hydrated may protect against kidney stones, constipation, asthma, urinary tract infections, coronary heart disease and even possibly some cancers.
