Explanation:

🆕 New Concept Discovered: Effects of alcohol on the human body
How alcohol impacts physiological systems and immunity.

Step 1: Analyze the question

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

Step 2: Evaluate the biological impact of alcohol

To defend against viral infections, the body relies on its immune system.

• Alcohol consumption, especially in excess, is scientifically proven to suppress and weaken the immune system.
• When the immune system is compromised, it becomes harder for the body to fight off invading pathogens, making a person more likely to get sick when exposed to viruses.

Step 3: Evaluate the given options

• "Teenagers often share drinks, therefore spread their germs around." — While sharing drinks can spread germs, this is a behavioral habit of a specific group rather than the biological reason why drinking itself increases susceptibility.
• "Alcohol makes it easier to forget putting a coat on at night." — Being cold does not directly cause viral infections like the cold or flu; pathogens (viruses) do.
• "Alcohol weakens your immune system." — This is the direct biological mechanism. A weakened immune system cannot defend against cold and flu viruses effectively.
• "Alcohol does not increase your chances of getting a cold or the flu." — This is factually incorrect, as alcohol consumption does increase these chances by suppressing immune function.

Answer:

Alcohol weakens your immune system.
