You just have to go around the coffee shop and smell the aroma of the coffee. The study, conducted by scientists from many countries, found that inhaling warm, strong coffee aromas can alter the activity of certain genes in the brain and reduce sleep deprivation.

Coffee is known to be a pick-me-up, but a study shows that you don't have to drink it to get a pick-me-up. You can just walk around a coffee shop and smell it.

Inhaling the warm, rich aroma of coffee can alter the activity of certain genes in the brain and reduce the effects of sleep deprivation, a multinational study found.

Researchers exposed lab mice to coffee and found that sleep-deprived mice expressed proteins with antioxidant properties in their brains that protected nerve cells from stress.
