Take a nap

Have you imagined ever about why it is always said to sleep for eight hours? It has been observed when a few pilots were allowed to sleep just for six hours in place of eight hours for a week, the next two days; the cortisol level was marked to have increased more than the normal. It is because when you sleep properly for 8 hours at night, the cortisol level comes to a normal level, and thus you stay away from any kind of serious stress. If you are somehow not able to complete the eight hours sleep at night, you may feel irritation the very next day. Thus, in this situation it is advised that you should take a nap whenever you can. Especially when you are getting hyper of stressed, you need to understand that your cortisol level must be rising, and you need a nap.
