Explanation:

🆕 New Concept Discovered: Physiological Effects of Alcohol
How alcohol impacts bodily systems and health.

Step 1: Analyze the question

The question asks why drinking alcohol increases a person's chances of catching a cold or the flu. Both colds and the flu are infectious diseases caused by pathogens (viruses) that enter the body.

Step 2: Evaluate the options

• "Alcohol weakens your immune system."

The immune system is the body's natural defense network against infections like viruses and bacteria. Consuming alcohol impairs the function of immune cells, making it harder for the body to fight off invading pathogens. This directly increases susceptibility to illnesses like colds and the flu.

• "Alcohol does not increase your chances of getting a cold or the flu."

This statement is factually incorrect because alcohol consumption is scientifically proven to suppress immune function.

• "Teenagers often share drinks and spread their germs around."

While sharing drinks can spread germs, this is a behavioral factor specific to a certain demographic and sharing behavior, rather than a direct biological consequence of drinking alcohol itself.

• "Alcohol makes it easier to forget putting a coat on at night."

While alcohol can impair judgment, being cold itself does not cause viral infections like the cold or flu; pathogens (viruses) do.

Step 3: Select the best biological explanation

The primary biological reason why alcohol consumption increases the risk of viral infections is its direct suppressive effect on the body's immune defenses.

Answer:

Alcohol weakens your immune system.
