What Causes Constant Yawning During Physical Exercise?
Could be due to electrolyte imbalance or oxygen deprivation.
Detailed Answer:
Thanks for asking on HealthcareMagic.
I have gone carefully through your query and understand your concerns. It seems that somehow you have developed an electrolyte imbalance. I would insist you to increase total fluid (water) intake and to take plenty of ORS (oral rehydration solution) to replenish the lost fluids and salts. Take juicy fruits like citrus fruits. They contain plenty of potassium which should help.
Paucity of oxygen could also be a factor and I would insist you to visit a ENT doctor to rule out any obstructive cause that could be impeding with the process.
Try the following technique while going to bed: Inhale over 6 seconds, hold for 7 seconds, exhale over 8 seconds, then repeat the process. It will make you relax and go to sleep easily.
Let me know what happens next and also if I could help further.
