[|AI|]  Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would like to explain that it is normal to have tachycardia and palpitations during physical activity and anxiety. Waking up is a kind of stressful activity for the human body, because you change your situation from silence and deep rest to daily activity full of stimuli.  Physical exercise can help you manage better this physiological changes, and reduce tachycardia. I recommend continuing to perform physical activity, as it is very helpful for good function of all your organs and your mind. Hope to have been of help! Best wishes,
