Line 2 baking sheets with parchment paper. Beat the ingredients at medium speed with a handheld mixer or a stand mixer with a paddle attachment. When you're done, the butter mixture should be light and fluffy. Beat for 30 seconds or until the ingredients are well combined. Alternatively, you can drop 2 teaspoons worth of dough at a time onto the baking sheet.

summary: Preheat the oven to 350F (180C). Place the butter, granulated sugar and brown sugar in a mixing bowl. Add the buttermilk, eggs and root beer extract. Whisk the flour, baking soda and salt together in a separate bowl. Add 1 cup of the dry ingredients to the wet ingredients and mix them at low speed until the dry ingredients are just incorporated. Keep adding the dry ingredients in 1-cup increments until you have incorporated all of the dry ingredients into the wet ingredients. Drop the dough onto your baking sheet using a cookie scoop. Bake 1 cookie sheet at a time for 10 to 12 minutes or until the cookies are set and lightly browned on the bottom. Place the cookies on the stovetop and cool them for 2 minutes and then immediately place the second baking sheet into the oven. Loosen the cookies from the first baking sheet with a spatula and transfer them to wire racks to cool completely. Add a fresh piece of parchment paper and an additional batch of dough to the first cookie sheet after it has cooled. Continue to bake the cookies, prepping one baking sheet while the other sheet of cookies is baking.

Many chemical detergents that include sulfates and added fragrances are irritants and can cause rashes, dryness, and redness. When doing your laundry, look for sulfate- and fragrance-free alternatives that will get your laundry clean but won't irritate your skin. One popular detergent alternative is "reetha" which is a nut from India that can be used as a soap in the washing machine. Creamy, moisturizing makeup products that are applied directly to the skin, such as foundation and concealer, can add hydration while minimizing the appearance of dry spots. Make sure you blend your makeup thoroughly, and remember to apply spot moisturizer throughout the day on any dry spots. It may be helpful to take a few days off from applying makeup to treat particularly bad dryness. During that time, focus on skincare and making sure you are hydrated throughout the day. A humidifier is a great tool, especially if you live in an area that experiences dry seasons. It increases the water vapor in the air and can make your skin more hydrated.

summary: Avoid chemical laundry detergents, which can irritate your skin. Invest in hydrating foundation and concealer if you wear makeup. Use a humidifier to reduce dryness in the air while you sleep.

Cardiovascular exercise prompts the production of nitric oxide in your body. Aim to do at least 30 minutes of moderate to intense cardio every day. This kind of exercise could include running, biking, swimming, rollerblading, dancing, or sped walking. If you can't schedule 30 minute sessions of exercise every day, break up the 30 minutes into 10-15 minute blocks. Nitrogen produces nitric oxide when metabolized in the body, and can be found in many vegetables. Similarly, most high-protein foods contain arginine, which produces nitric oxide when broken down in the body. Each day, try to add 1-2 servings of foods like: Kale Spinach Broccoli Brussel sprouts Beets Legumes Nuts Beans Fish (e.g. salmon) Meats (e.g. beef, chicken) Cheese Eggs Exposure to UV light prompts the body to unlock its own stores of nitric oxide. Get outside for least 20 minutes a day, during work breaks or for short walks. Wear SPF sunscreen to protect your skin from sun damage.
summary: Get at least 30 minutes of cardiovascular exercise every day. Eats foods that are high in nitrogen and protein. Get at least 20 minutes of sunlight each day.
