Why water is so important as you age (and how to get enough)

Healthy meals. Exercise. A good night's sleep.

These are all key parts of a healthy lifestyle. But as you age, there's one often overlooked habit your body really needs you to put on your to-do list: Drink enough water.

Older adults are more at risk of becoming dehydrated. The aging process decreases the body's ability to sense thirst, so you might not reach for water even though your body needs it. Older adults are also more likely to have conditions or take medicines that increase the risk of dehydration.

Why drinking water is important

Every single body system is dependent on proper hydration, from your brain to your bones. For example, water:

• Gets rid of waste through urination, bowel movements and sweat.
• Keeps the body temperature regular.
• Lubricates and cushions joints.
• Protects sensitive tissues.

There could be another big benefit: One recent study found that being well hydrated might make a person less likely to develop chronic illness and more likely to live longer.

How much water do you need?

In general, adult women need to get about 11.5 cups of water each day. Adult men need about 15.5 cups. But this number can vary based on your health, activity levels and other factors.

If you have questions about exactly how much water you should drink each day, ask your healthcare team.

Simple changes can make a big difference

Check out these tips and tricks to help make drinking water your new healthy habit.

1. Eat your water. You might be surprised by how much water is in fresh food. In fact, many fruits and vegetables, like watermelon and spinach, are almost 100% water by weight.
2. Jazz up your water. Don't like the taste of plain water? Add a few pieces of fruit, like strawberries, lemon or lime. You also can add herbs, like fresh basil or mint, for a refreshing twist.
3. Stick to a schedule. This can help keep your water intake on track throughout the day. If you have trouble remembering to drink, set reminders or a timer.
4. Go bubbly. Look for unsweetened sparkling water. If it's not flavored, add fruit or a small splash of 100% fruit juice.
5. Take water with you. Get a reusable water bottle or tumbler and keep it filled. If you like your drink to stay cold, look for one that is insulated. Helpful tip: Make sure it will fit in the cupholder in your car.
6. Go high tech. There are several smartphone apps that can help figure out how much water you need, track your intake and remind you to drink.
