Exercise will help you look better, but it will also produce endorphins, which will make you feel better, too. When you feel better about yourself, you naturally act more confident, which translates into beauty when others look at you.  To start, try working out for 30 minutes 3 to 4 times a week. As exercise becomes more of a hobby, you can increase your sessions. You don’t have to belong to a gym to exercise—try walking around your neighborhood, biking, doing exercise videos at home, or joining a sports team at school. Fresh, whole foods are full of nutrients that are good for your skin and which will help make you look more beautiful. When you snack, try to eat fruits and veggies instead of processed foods. Sugars can wreak havoc on your skin, so eat sweets in moderation. When you choose foods, think of eating all the colors of the rainbow. Red bell peppers, oranges, spinach, blueberries, and other fruits and vegetables will help hydrate your skin while providing great antioxidants. Aim to drink 8 to 9 glasses of water every day. If it’s hot out or if you’ve been exercising, you may need to drink more to keep your body hydrated. Water plays a big role in how your skin looks!  A glass of water is 8 ounces (230 g). Pay attention to the color of your urine when you go to the bathroom. If you’re drinking enough water, your urine should be a clear or light-yellow color. If it’s darker than that, you may be dehydrated. It may be tempting to squeeze in a few extra hours of studying or socializing, but try making your sleep a priority. Not only will you feel better and more capable of handling day-to-day stress, but your body will look better, too.  Try always going to sleep and waking up at the same time, even on the weekends. Turn off all of your electronics 30 minutes before heading to bed. You can look as beautiful as possible, but with the wrong attitude, you’ll come across as a very unattractive person. Science shows that people think kind individuals are better looking than those who are mean or rude. Try to be positive, treat others with kindness, and look for the good around you. Being kind to others (and to yourself) is a great way to radiate beauty to everyone around you. Believing in yourself is the best way to impact how others perceive you. Work on accepting yourself for who you are, and focus on all the things you can do well. When you feel good about yourself, you’ll look good, too. Smile at others, be welcoming, and trust that you are smart, beautiful, and capable of getting through your high school years.

Summary:
Exercise for better mental and physical health. Eat foods that are healthy and nutritious for glowing skin. Drink water throughout the day to stay hydrated. Get 7 to 9 hours of sleep every night for optimal health benefits. Practice being kind to everyone you meet. Be confident in yourself and in your beauty.
