Is it normal to keep yawning?
Yes, repeated yawning is usually harmless and often means you’re tired, bored, or simply reacting to someone else yawning. If it keeps happening even when you’re well rested, it may be worth looking into.
Yes—yawning a lot is usually no big deal. It often happens when you’re sleepy or bored, and yawning can also be contagious, so sometimes it seems to come in a whole chain reaction. You don’t have to be short on oxygen for it to happen; that old explanation doesn’t really fit the evidence.
If you’re yawning unusually often despite getting enough sleep, or it’s a new change that’s bothering you, consider checking in with a healthcare professional. Some medicines and sleep problems can contribute, though most yawning spells are just your body being your body.
