Effects Of Sleep Deprivation

Ever notice how the smell of food creeps up on you more easily when you’re tired?

No, it’s not your imagination! Science has just confirmed it. Sleep deprivation seems to increase the brain’s sensitivity to food smells.

Researchers at Northwestern University ran a study in which the subjects inhaled both food and nonfood odors on four hours of sleep. Weeks later they repeated the exercise on eight hours of sleep. The results? When tired, participants showed greater brain activity, in response to food smells than they did when they were rested.

So is that why sleep deprivation is linked to weight gain? Makes sense!
