Explanation:
The sleep defict is the term used to describe the "debt" of sleep that some people develop when they sleep little and do not provide the body with the rest it needs and that only well-slept nights can provide. This is very dangerous, as it promotes malfunction of the body in the long run.
There are several factors that can lead to a lack of sleep, such as constant use of computers and cell phones, sugary drinks, use of the bed to do activities other than sleeping and resting, processed foods, among others. Coincidentally, teenagers have all these factors making their lives a perfect storm of sleep deficit.
