Sleep More: You'll Be Less Sensitive to Negative Emotions

We know that sleep helps our body recover from the day and repair itself and that it helps us focus and be more productive. It turns out sleep is also important for happiness. In NutureShock, Po Bronson and Ashley Merryman explain how sleep affects positivity: Negative stimuli get processed by the amygdala; positive or neutral memories gets processed by the hippocampus. Sleep deprivation hits the hippocampus harder than the amygdala. The result is that sleep-deprived people fail to recall pleasant memories yet recall gloomy memories just fine.
