Thank you for your query on Healthcare Magic.
This type of deep breaths without an underlying respirator
problem may be related to
3. Phobias and scary things which caused due to watching TV shows of scary things
4. Boredom and lack of sleep in the night times.
Anxiety and stress related phobias, scary shows and continuous watching television may lead to deep breathing episodes with feeling of chest tightness
and knots in the chest.
I advise you to decrease his viewing time of television to less than one hour within 24 hours.
Adequate night time sleep is mandatory to be active on day time.
Consult your Pediatrician
on appointment to look for the other causes of rapid breathing like respiratory problems and anemia
Hope I have answered your query.
