. Exercise is an excellent way to control anxiety naturally. If you are prone to anxiety, then try to get at least 30 minutes of moderate physical activity every day, such as walking, biking, swimming, or taking an aerobics class.  You may also benefit from adding more activity during your regular activities, such as walking or riding your bike to work, parking further away from entrances at stores, and taking the stairs instead of the elevator. If you experience anxiety and panic symptoms, it’s best to stay away from substances that can provoke symptoms. Avoid tobacco, coffee, and caffeinated beverages. Avoid stimulants as well, which can be a part of diet pills or cold medicines. Because many symptoms from panic attacks are bodily symptoms, take care of your body and treat it well. Eat and prepare healthy meals that support your overall health. Foods can affect your mood and emotions, so make sure you get your vitamins and nutrients to balance your mood and healthy functioning. Avoid skipping meals and have snacks on hand when you need them. You may want to keep some nuts or dried fruit in your car if you get hungry while driving. Get plenty of sleep each night. Most adults need 7 ½ to 9 hours of sleep each night, and children need up to 13 or 14 hours each night of sleep, depending on age. Especially if you are stressed, your body needs more sleep.
