Most cases of morning anxiety are simply generalized anxiety. You wake up feeling anxious or stressed about
your day, but otherwise you don't necessarily have specific attacks or actions. You're simply stressed every time you wake up.
I have this very same thing but never noticed any problem with my facial muscles.
The absolute most common reason that people experience anxiety in the mornings is because they experience stress throughout the day. When they wake up, their body essentially floods them with anxiety over what their day is going to be like. It's especially common for those with stressful jobs, but may affect those with panic attacks and other daily stresses as well. Waking up makes their body feel tense over the probability of a stressful day, and morning anxiety is the result.
Daily exercise has been show in several studies to be as powerful or more powerful than some of the leading anxiety medications. When you wake up in the morning, your body has all of these extra energy from sleeping and all of this anxiety that needs to be reduced for your day to go better. Immediate exercise – running, biking, or anything else that you can do – is the fastest and best way to cut down on that anxiety dramatically.
Whether you need to seek outside help or commit to an at-home anxiety cure, you need to make sure that you're dedicated to living a life free of anxiety. Once you do, you'll experience less morning anxiety as a result.
I hope this helps you in some small way.
