I keep getting heavy deep sighs for no reason and theres nothing borthering me whats this suppose mean?

Question

And What Can I Do To Stop?

Answer 1

If you find yourself compelled to constantly take very deep, slow breaths, you should see a doctor; this is a sign of metabolic acidosis.  If you are diabetic, you should definitely see a doctor if you have this sign.

If you just sigh a lot from time to time, that's psychological.  If you have no other symptoms, it's probably nothing to worry about.

Answer 2

Boredom...

Or you could be out of breath...when you sigh, you take a deeeep breath.
