Overcoming a challenge requires power and fortitude, it's a good idea to arrive well-fed and rested. (Having a few cheerleaders on your corner doesn't hurt either.) Here's how to naturally reduce anxiety. It's crucial to look for yourself. According to studies, getting a good night's sleep — 7-9 hours is best — makes you feel less worried and more confident. Physical activity during the day will aid in better sleep, but you already knew that! Eating real, unprocessed food — lean protein, whole grains, legumes, fruit, nuts, and vegetables, as well as the occasional piece of dark chocolate! — will help you maintain a consistent level of energy. Spikes in blood sugar are caused by fast food and processed snacks (cookies, candy bars, and French fries).
