Is helium harmful to humans?
Can helium make you sing higher?
That’s because helium is so much lighter than air. When sound waves speed up but their frequency stays the same, each wave stretches out. It’s a gas that is much heavier than air, so when it is inhaled, it shortens sound waves so the lower tones in the voice are amplified and the higher ones fade out.
How is helium good for the environment?
When you breathe in helium, your voice travels much more quickly across your vocal cords. Breathing a lot of helium, however, can be dangerous. Prolonged inhalation of helium can lead to an inadequate amount of oxygen in the lungs and blood. This, in turn, can lead to brain injury and, in rare cases, even death.
Wildlife can become tangled in them or can eat the balloon scraps, with sometimes fatal consequences. Helium balloons, their strings and ties often end up snaring birds or aquatic wildlife, or get swallowed when the animals mistake the latex or foil for food.
Is helium dangerous to work with?
Is helium really that dangerous? It can be. Breathing in pure helium deprives the body of oxygen, as if you were holding your breath. If you couldn’t breathe at all, you’d start to die in minutes—as soon as your body exhausted the supply of oxygen stored in the blood.
