Evaluate the physiological impact

Using the Physiological Effects knowledge point, we analyze how alcohol interacts with the human body's defense mechanisms. Alcohol consumption, especially in excess, impairs the body's ability to fight off infections.

Alcohol suppresses immune cell function, reducing the body's ability to defend against viruses like influenza and rhinovirus. This directly weakens the immune system, making the individual more susceptible to illnesses.

Compare the given options

• Option 1 suggests alcohol lowers body temperature, which is a temporary sensation but not the primary biological reason for increased viral infection rates.
• Option 2 states alcohol weakens the immune system, which directly aligns with established medical science.
• Option 3 suggests it strips protective throat linings, which is not the primary systemic cause of getting a cold or flu.
• Option 4 claims alcohol does not increase these chances, which contradicts the premise of the question.
