Expert Q&A: Determining if You're Too Tired
Q: How do I know if I'm too tired to:
Drive a car?
Care for my kids or someone else?
People use the terms "fatigue" and "sleepiness" interchangeably, but how do you differentiate the two?
There are three ways:
1. If someone is sleepy, she will experience heavy/droopy eyelids, as well as head-nodding or dozing off, which suggests she is more than just fatigued.
2. If she is given the opportunity to fall asleep and is able to fall asleep, she is suffering from sleepiness. If a person who is suffering from fatigue is presented with the same situation, she wouldn't necessarily be able to fall asleep.
3. If she is sleepy, but well-rested, the sleepiness will subside. This is not the case for someone who is fatigued, as a well-rested person will not necessarily be cured of fatigue.
If you are experiencing sleepiness, you should not drive a car, care for someone's children, or operate machinery and you will not be able to work efficiently.
