Question

according to the article, what is one lifestyle change that can help boost your immune system?
a taking a lot of nutritional supplements.
b managing stress levels.
c using hand sanitizer frequently.
d avoiding all contact with people.

Explanation:

Managing stress levels is a lifestyle - related factor that can positively impact the immune system. High stress can suppress the immune response, so reducing stress helps boost it. Taking excessive nutritional supplements may not be beneficial and can even be harmful. Frequent use of hand - sanitizer is more about hygiene to prevent infections rather than boosting the immune system. Avoiding all contact with people is an extreme and not a practical or healthy lifestyle change for immune - system boosting.

Answer:

B. Managing stress levels
