Don’t think it’s weird. It’s just your body responding to relaxation.
There is a simple physiological explanation for that: prayer brings your body into a state of calm and stillness, right? And when that happens, your parasympathetic nervous system kicks in - that’s the part responsible for rest and relaxation.
Basically, your body switches gears from alert mode to rest mode. So you sit down to pray, you get still, and your body goes, ‘Oh, we’re transitioning now.’
Another interesting one is thevagus nerve. It’s a major nerve that runs from your brainstem down through your body and controls functions like heart rate and digestion. When your face, jaw, and throat muscles stretch during a yawn, it activates that nerve, helping your body relax more.
Plus, yawns also release dopamine and serotonin - calming chemicals that balance cortisol (science-backed).
Your nervous system basically signals that you feel safe enough to let go. You’re letting your guard down in God’s presence, and your body is responding.
Keep praying. Your body calming down might even be the point.
