Question

which of these health issues may be caused by sleep deficiency? a. cancer b. obesity c. lung disease d. allergies

Explanation:

Sleep deficiency disrupts hormones (ghrelin and leptin) that regulate hunger and fullness, increasing appetite for high-calorie foods. It also reduces energy for physical activity, contributing to weight gain and obesity. Other options (cancer, lung disease, allergies) have primary causes unrelated to sleep deficiency.

Answer:

B. Obesity
