Yawning is not directly linked to being sleepy. It is a reflex that can be triggered by various factors, such as boredom, a need for more oxygen, or changes in brain temperature. While yawning can sometimes indicate that a person is tired, it is not always a reliable indicator of sleepiness.
For many years yawning has been associated with one being tired, bored or stressed. If one wishes to learn more about yawning, the site with the most detailed information would be on Wikipedia.
Because you're tired.
it means either you are bored or they are tired
None ! Yawning is either the body signalling you're tired, or that you're short of oxygen. Nothing to do with muscles !
yes............and it can also mean you are tired
Um, I shouldn't think that yawning itself causes heart palpitations, but if you are extremely tired, there is more chance of you having a palpitation.
they say its due to a lack of oxygen to the brain....it happens to me as a result of me being around air conditioninWell I always yawn when I'm tired, it gives me more energy but it makes me sleepy or when you se someone else yawning constantly!-Icelopbunny
They will feel dizzy. Weak. Tired and they will keep yawning.
I am taking a antidepressant and can't stop yawning is there anything I can do without stopping the medication?
You can't stop yawning because when you yawn your body is trying to get more oxygen into you body to try and stay awake. If you are yawning constantly your body is trying to keep you awake, the longer you stay awake, the more you will yawn.
being tired is that you're tired,and tired of being tired is different because it means that rather not be tired, but you are tired
