One thing that is important to remember is that parial sleep loss is cumulative. That means that if you get 30 minutes less sleeping time than your body needs each day during the week, your body will want to make up two and a half hours of sleep during the weekend, or whenever you can afford to sleep in.
In my case, there are times when I miss out on more than an hour of necessary sleep each night, building up a large deficit. When I let my body and mind recouperate, I’m missing out on time that could be spent working on projects, earning money, or doing chores that will free more valuable afternoon time when I can work efficiently later in the day.
