Your white blood cells rely on oxygen to enable them to fight viruses and bacteria. If they are operating without enough oxygen, then they are unable to destroy harmful invaders. It also helps to fight cancerous tumors and helps to prevent an overgrowth of scar tissue in wounds. However, overconsumption of alcohol can impair the function of the immune system and weaken it. When the balance is disrupted, it becomes difficult for the good bacteria in the gut to overcome the bad bacteria.
