While changing eating high energy foods for anxiety can definitely help you get a handle on stress, it should be combined with other lifestyle changes. Take some time out of your day to practice meditation or even simple breathing techniques. As well, make sure to get the suggested amount of sleep every night as not getting enough sleep releases cortisol (the stress hormone) into your blood stream. It can take some time to make these changes, so try to do a little bit every day. Before you know it, you’ll find that you’re stress levels are down.
