[|Human|] I was laughing and moved my head really fast and started coughing and felt lightheaded after like i was going to faint and my legs were like jello. I feel a lil better now that was like 15 mins but got a headache. Did I just lack oxygen to the body from coughing and laughing so hard
[|AI|]  Hello ! Thank you for your question on Chat Doctor! I think you are right and the laugh and coughing may have caused a gap of oxygen perfusion to your brain. Another explication would be the abrupt raise in the intrathoracal pressure causing a legal nerve response and other changes. The muscles of your face and neck may be contracted from hyperextension during laughing and cause headache and dizziness. So you see that there are a lot of possible explanations to this situation, but nothing serious, to be worried about. Hope to have been helpful! Best wishes!
