How much water should you drink?

How much water should you drink a day? You probably know that it's important to drink plenty of fluids when the temperatures soar outside. But staying hydrated is a daily necessity, no matter what the thermometer says. Unfortunately, many of us aren't getting enough to drink, especially older adults. Older people don't sense thirst as much as they did when they were younger. And that could be a problem if they're on a medication that may cause fluid loss, such as a diuretic. 

Here are some reasons our body needs water:

1. It lubricates the joints

2. It forms saliva and mucus

3. It delivers oxygen throughout the body

4. It boosts skin health and beauty
