In today's high-tech, fast-paced world, people are more stressed out than ever. This stress seems to come from obvious sources, like financial hardship or long work hours. You might be surprised to learn that these 5 simple things are subliminally stressing you out!

Even if you're afraid of the dark, you might want to rethink sleeping with a night light. You might feel like you slept well, but the truth is scarier than anything creeping in the dark.
