Inhaling helium displaces oxygen, putting you at risk of side effects such as dizziness, loss of consciousness, and even death.

You inhale helium from a balloon, and almost as if by magic, you sound like a cartoon chipmunk.

Harmless as it may seem, though, inhaling helium can be dangerous — deadly, in fact. There are numerous case reports of serious injury and even death caused by helium inhalation.

From 2000 to 2019, an estimated 2,186 injuries related to helium inhalation were reported in United States hospital emergency departments. Most of the patients were male children between the ages of 6 and 12.

What happens when you inhale helium?

When you inhale helium, it displaces oxygen. This means that as you inhale, your body is only getting helium.

Oxygen plays a role in every function of your body. Anytime you don’t get enough of it, you’re putting yourself at risk. Many of the risks are the same as with other inhalants.

What if I’m just inhaling from a balloon?

Typically, inhaling a single breath of helium from a balloon will have the desired, voice-altering effect. It might also cause a bit of dizziness.

That said, there’s always the potential for other effects, including:

nausea
lightheadedness
passing out

Inhaling helium from a balloon isn’t likely to cause major health issues or kill you, but it’s not impossible. There have been news reports of some folks, particularly young children, dying from asphyxiation after inhaling helium from a balloon.

What about helium from other sources?

The majority of serious health issues and deaths related to helium inhalation involve inhaling helium from a pressurized tank. These are the same tanks used to fill helium balloons at events or party supply stores.

Tanks not only hold a lot more helium than your everyday party balloon, but they also release the helium with much more force.

The more pure helium you inhale, the longer your body is without crucial oxygen. Breathing in pure helium can cause death by asphyxiation in just minutes.

Inhaling helium from a pressurized tank can also cause a gas or air embolism, which is a bubble that becomes trapped in a blood vessel, blocking it. The blood vessels can rupture and hemorrhage.

Finally, the helium can also enter your lungs with enough force to cause your lungs to rupture.

Can you get high off helium?

Some people may inhale helium to get high, and it can be addictive.

The vapor is quickly absorbed by the lungs and, much like the effects of alcohol, may cause feelings of excitement or happiness.

But because these feelings usually don’t last for more than a few minutes, people may continue inhaling helium to sustain the sensation. This increases the risk of injury or even death.

I just inhaled some — am I in danger?

If you’ve inhaled a bit of helium from a balloon and are just feeling a little dizzy or have a mild headache, you’re probably fine. Have a seat, breathe normally, and wait it out.

If your symptoms are more severe, or if you’ve lost consciousness, have someone take you to the nearest emergency room — better safe than sorry.

If you’ve breathed in helium from a pressurized container, your symptoms could be a bit more severe. Again, if you feel fine other than a bit of dizziness, you probably don’t have anything to worry about.

Watch for symptoms that could be a sign of more serious issues in the coming minutes and hours.

If you or someone else experiences any of the following after inhaling helium, call 911 or local emergency services right away:

low blood pressure
trouble breathing
irregular heart rate
blurred vision
chest pain
weakness or paralysis in one or more limbs
bluish lips or skin (cyanosis)
coughing up blood
seizures
loss of consciousness

So, does this mean I can never get that high-pitched voice again?

Not necessarily, but it’s important to remember that doing so isn’t without risk. That said, you should definitely avoid giant balloons and pressurized tanks. You should also steer clear of all helium if you have a lung or heart condition.

Stick with small party balloons if you must and follow these tips:

Do it sitting down in case you get lightheaded or pass out.
Make sure someone else is with you who can help if symptoms do occur.
Don’t let children inhale from balloons. Not only are they more likely to have a bad reaction, but they’re also more prone to inhaling parts of the balloon or choking.

The bottom line

A one-off breath of helium from a small balloon for a laugh is unlikely to be catastrophic, but it can cause dizziness and make you pass out.

Have a seat so that you don’t have far to fall and avoid inhaling from a helium tank or giant balloon.

Even a few seconds without oxygen can have serious effects.
