Always drink plenty of water before and after practicing yoga postures. Listen to your body and give it what it needs to function.
Try reducing your caffeine, alcohol and sugar intake. They give little nutritional benefit while being difficult for the body and mind to digest. You might also try reducing dairy, eggs and wheat, as they are common low-level allergens. No matter what, practice, even if you don’t follow these nutritional guidelines.
Get plenty of sleep, at least 7 hours per night. Sleep is where our body and mind regenerate. Our metabolism and physical and mental functions of the body need sleep in order to work properly. If you are tired or exhausted, rest. No amount of food, stimulants or yoga can replace sleep.
