A morning workout is supposed to give you energy, not leave you feeling drained. Early morning yoga should clear your mind and set you up for your day, not leave you ready to curl back up into a sleepy cocoon. Before you blame yoga, consider your habits and reactions to yoga as a potential cause for your sleepiness.
The National Sleep Foundation says that adults need between seven and nine hours of sleep per night. Your intention to fit in yoga before the sun rises is good, but if it causes you to skimp and get less than these recommended hours, you could wind up tired. Get to bed a bit earlier so you wake up refreshed, not groggy, for your practice.
Choose an active yoga session for morning practice. Flowing postures linked together with the breath, such as Vinyasa or even a Power yoga class, can invigorate you. Classes that emphasize Sun Salutations, standing postures and balances wake you up for the day. Save restorative practices or soothing floor-based routines for evening, as they calm the nervous system and induce sleep.
Choose a yoga class that matches your abilities. While vigorous can be good first thing in the morning, if it is too taxing - it could use up your energy stores. An Ashtanga Vinyasa class or one full of challenging arm balances and core exercises may tire a beginner out. Find a class that gets you moving, but at a level that leaves you feeling good - not spent.
Although yoga is supposed to help calm stress, the process by which it does so can be emotionally exhausting initially. With regular practice, you might find certain asanas, or poses, stimulate energy centers and stored memories that make you feel anxious or wrought with sadness. Confronting these emotions is important, but it can tire you out. Sometimes, you may push away these unpleasant feelings and that, too, takes energy. Yoga is a practice that requires you to be in the moment and sometimes let go of beliefs and emotions that are not serving you. It can be taxing and leave you a bit tired, but in the long run, it will help you feel more emotionally and physically invigorated.
