Question

which of these health risks may be caused by sleep deficiency?

a. allergies

b. obesity

c. cancer

d. lung disease

Explanation:

Sleep deficiency can disrupt hormonal balance, including hormones that regulate appetite (like leptin and ghrelin). This disruption can lead to increased hunger and cravings, often for high - calorie foods, which can contribute to weight gain and obesity. Allergies are mainly caused by immune responses to allergens, cancer has complex multifactorial causes (genetic, environmental, etc.) not directly related to sleep deficiency, and lung diseases are related to factors like smoking, infections, or environmental pollutants rather than sleep deficiency.

Answer:

B. Obesity
