The swallow causes a brief interruption in breathing. When you swallow, you must hold your breath for a few seconds to shut the airway (this prevents any food or fluid from entering the lungs). After swallowing, you will need to take several deep breaths as you open up your airways. Breathing while eating is important because without it you would asphyxiate due to lack of oxygen to your brain and other organs. However, you should only try to do this if you are experienced at swallowing large quantities of food at one time because it can be difficult and pose some risks to your health. If you are not used to eating that much at once you should start with small amounts of food until you are comfortable doing so. Swallowing and breathing are two processes that must happen together or neither will be able to function properly. If you are not sure whether you can swallow and breathe at the same time, ask someone to check for you. If you feel dizzy when you try to swallow and breathe at the same time, then stop what you are doing and rest for a few minutes before trying again. In conclusion, you can swallow and breathe simultaneously but it is best to wait until you have finished eating before doing so. This way you do not experience any problems and can continue with your meal unharmed.
