If you're yawning, sluggish and can't focus, those are some of the obvious signs that you're not sleeping enough. But there are less obvious signs you might not know about.

Here are some more subtle signs you may never think about that tell you that you need more sleep, according to an article at msn.com.

Under the weather. If you notice that you seem to always be fighting a bug or setting sick, that weak immune system could be your body telling you it's craving some rest.

It is what it is. Believe it or not, if you catch yourself using cliches, it may actually be because using them instead of coming up with a better way to express yourself takes less energy and it's your brain's way of telling you to get some sleep.

Yes...I mean no. Indecisiveness can be a signal that you are not resting enough.  If you want to get scientific about it, the lack of sleep decreases blood flow to the pre-frontal cortex of the brain and that's the part of the brain that helps you...well...make up your mind.

So, these signs of lack of sleep may not be as obvious as some of the other ones we're more used to hearing, but if they sound familiar, you may need to figure out a way to rest a little more. Easier said than done, right? Uh-oh that's a cliche, isn't it?. If you need me, I'll be at my desk taking a nap.
