Every day we are faced with the challenge of making the right decision concerning our choice of food and health. Of all the food and beverage choices you face every day, water essential to keeping you alive. But it’s not the only reasons to drink it. Here are 5 compelling reasons:
It will help you reduce stress : Water drives basic body performance. All of the systems in the body require water for proper functioning, and so do 90 percent of all chemical reactions in the body. Stress taxes all your basic body systems and when you're dehydrated, the effects are magnified. Given that more than half your body weight is water, just a 2-percent reduction in hydration has a dramatic impact on energy levels and cognitive function. And dehydration further raises levels of cortisol -- the "stress hormone."

Water won't wash your stressors away. But it can provide you with more energy, ease tension, slow breathing, and reduce the strain on your heart.
It will help you lose weight: Water is filling, so you feel fuller and eat less. A study found that those who drink water before meals consume an average of 75 fewer calories per meal. (Make that twice a day over a year, and that could add up to 14 pounds!) Water drinkers swap this zero-calorie beverage for sodas and other caloric beverages.
You'll be less apt to get sick: Hydration keeps your mucus membranes in top working order – they are gatekeepers to the natural defence system that helps keep out germs such as cold and flu viruses. When these tissues dry out, germs can more easily penetrate to the nasopharynx, where the nasal passages and mouth meet. And if you catch a bug anyway, the severity of your illness is more likely to be lower if you've been drinking a lot of water.
Water keeps you more comfortable: The act of drinking it will keep you warmer on a cold day -- and cool you off on a hot one. Your internal thermostat works better when you're well hydrated. Water helps regulate body temperature.

The body's temperature-regulating system, governed by the hypothalamus in the brain, is constantly picking up information that allows it to make adjustments to maintain a fairly steady core temperature. Hot sun? You'll sweat to cool down. Under the rain? The hypothalamus will know you're losing heat through your head and work to produce extra energy, such as shivering.

But these mechanisms work less well if you are dehydrated.
It will help regulate your blood pressure: Drinking water activates the parasympathetic nervous system -- related to the "fight or flight" system that makes you more alert, elevates blood pressure momentarily, and boosts energy. Not drinking enough water on a regular basis can also raise blood pressure. That's because dehydration causes blood vessels to constrict as the body strives to conserve water that it loses through perspiration, urination, and breathing. When blood vessels constrict, however, the heart pumps harder, bringing blood pressure
