Summer is upon us, but we still need to support good immune system health. Here are some helpful tips: 1) Keep sugar low in the diet by making your own sun tea, slushy drinks, or smoothies. 2) Eat lots of salads with fruit and nuts to provide some hidden hydration. 3) Check your city for local outdoor events, such as qi gong, tai chi or yoga in the park. This is a great way to get some exercise and promote good breathing to support a relaxed parasympathetic nervous system. 4) Finally, don’t forget about getting enough high-quality sleep!
