In one sentence, describe what the following article is about:

If you're dehydrated, your skin is dehydrated, and if it gets too dry, it can become ashy. If you're a woman, you need about 11.5 cups (2,700mL) of water a day, and if you're a man, you need about 15.5 cups (3,700mL) each day. However, a good rule of thumb is to drink enough water so that you never feel thirsty during the day. Other beverages like tea and juice do count toward your water intake, though you should be aware that juice can add empty calories. If you have trouble getting enough water during the day, try carrying a reusable water bottle around with you, and fill it up whenever you get a chance. Try adding slices of fruits and veggies, like grapefruit, orange, and cucumbers, to make your water more refreshing. Getting all the right nutrients in your diet is an important step to creating beautiful skin. Make sure to include fruits and veggies at every meal. In addition, eat lean proteins such as chicken and fish; healthy fats like nuts, avocados, and fish; whole grains; and low-fat dairy. Avoid foods that are high in fats, sugars, and processed carbs, like chips, sodas, candy, fast food, and fried foods. It can be really hard to quit, but if you want healthy skin, you should stop smoking or using any other products that contain nicotine. Cigarettes deprive your skin of oxygen. In turn, not as many nutrients are carried to your skin cells, which can result in more lines and wrinkles. If you need help quitting, talk to your doctor and ask your friends and family for support. While you may know that stress can affect your health, you may not know that it can affect your skin. For instance, stress can cause acne breakouts on your face, which can then lead to scarring. One thing you can do to cut down on stress is to learn to say "no" when you have too much going on. If you're juggling a stressful situation at home and a new job, it's okay to say "no" to baking for the school bake sale. To help relieve stress, participate in hobbies you enjoy. Whether you like to bowl, paint, or watch movies, make sure to make time for the things you enjoy. You can also try practicing deep breathing when you find yourself stressed out. Take a moment to find a quiet place. Close your eyes, and focus on your breathing. Breathe in slowly, counting to 4 in your head. Then, breathe out, counting to 4 again. Keep it up until you feel yourself calm down. Sleep is essential for a lot of different reasons, but it can actually affect your skin health, as well. That's because sleep helps restore the balance of fluids in your body that are essential for healthy, glowing skin. In addition, getting plenty of sleep will help you handle stress better, which can also affect your skin. If you're struggling with dry skin, it can be beneficial to make your home more humid to help keep your skin from getting dry and ashy. Consider adding a humidifier to your bedroom to soak up the benefits of more humid air. While you can do this any time of year, it's especially beneficial during the dry winter months.

Summary:
Drink plenty of water throughout the day. Eat a diet rich in fruits and veggies. Quit smoking cigarettes, if you use them. Keep stress under control. Get a good nights' sleep every night. Add moisture to your home to combat dry skin.
