Final answer:
Sleep deficiency can lead to obesity, lung disease, and an increased risk of certain cancers.
Step-by-step explanation:
Sleep deficiency can contribute to various health issues. One of these health issues is obesity. Lack of sleep can disrupt the balance of hormones that control hunger and satiety, leading to overeating and weight gain. Another health issue caused by sleep deficiency is lung disease. Chronic sleep deprivation can weaken the immune system, making individuals more susceptible to respiratory infections and respiratory diseases. While sleep deficiency does not directly cause cancer, it is associated with an increased risk of certain types of cancer, such as colorectal and breast cancer. Sleep deficiency is not typically linked to allergies.
