You’ll keep things regular
Every cell in your body requires water, and if your body is lacking hydration in one area, you could find it harder to pass a stool. “When your body needs to have more water in a certain area, it will take out of less essential areas—and that means it will take away from your digestive system,” says Bruning. But by staying hydrated, you can avoid constipation. Learn the 12 surprising reasons you could be constipated.
You’ll get better at kicking a cold
Another one of the benefits of drinking water is that it can help you heal faster. There’s a reason your doctor tells you to drink more fluids when you’re coming down with something. Your body has to ramp up to launch an attack against the germs when you’re sick, which means your cells need more calories and fluids to keep up with the demands. For instance, you’re losing fluids when your nose starts to run in your body’s attempt to flush out pathogens. “Because you need that strong function to fight off sickness, you need hydration then too,” says Bruning. Here’s exactly what to eat when you have a cold.
You might get fewer headaches
If you’re prone to headaches and don’t drink enough water every day, good hydration could give you some relief. When your body doesn’t have the fluids it needs, it can’t transfer important nutrients as easily, and a headache is your warning sign. “It’s your body’s way of signaling that something is amiss,” says Bruning. “Your head is saying, ‘I’m dehydrated—this affects me too.’” Watch out for these signs that you’re drinking too much water.
