Question

which of these health issues may be caused by sleep deficiency?
a. allergies
b. emphysema
c. hormone imbalance
d. cancer

Explanation:

Sleep deficiency can disrupt the body's hormonal - regulating processes. Allergies are mainly immune - system responses to allergens, emphysema is related to lung damage often from smoking, and while sleep may play a role in cancer risk, the link is more complex. Hormone imbalance is directly affected by sleep deficiency as sleep is crucial for the regulation of hormones like cortisol, insulin, and growth hormone.

C. Hormone imbalance
