Technically speaking, you will be able to chug the most water at once from a bottleneck that most perfectly matches the size of your mouth. Bear in mind that your throat may not be able to keep up with this volume of water. If you do use a plastic water bottle, you can try scrunching the end of the bottle as you chug. This will force the water out of the bottle more quickly than it would flow otherwise. Again, bear in mind that faster does not mean healthier. [1] X Research source
Don’t tip your head back forward until you’re done chugging water. If you shift your throat passage while the water is still draining, then that water might be slowed by the muscle contraction. This can cause you to choke. Never chug while lying down. Chugging while horizontal increases the likelihood that the water will slip into your windpipe, causing you to choke.
Be careful! It is easy to accidentally pour the water into your windpipe, which can cause a series of choking spasms.
It’s estimated that consuming more than 1. 5 liters/hour over several hours can greatly increase your risk of hyponatremia. [3] X Trustworthy Source Mayo Clinic Educational website from one of the world’s leading hospitals Go to source
Make sure that there is no ice in the water. It is quite possible to choke to death on a chunk of ice.
