Lack of Sleep
Sleep is a major factor in your mood. If you are sleep deprived you could become more irritable, angry, more prone to stress, and less energized throughout the day. "Studies have shown that even partial sleep deprivation has a significant effect on mood. University of Pennsylvania researchers found that subjects who were limited to only 4.5 hours of sleep a night for one week reported feeling more stressed, angry, sad, and mentally exhausted. When the subjects resumed normal sleep, they reported a dramatic improvement in mood."

“So if hunger provokes wailing and wailing brings the breast; if the breast permits sucking and milk suggests its swallow; if swallowing issues in sleep and stomachy comfort, then need, ache, message, object, act, and satisfaction are soon associated like charms on a chain; shortly our wants begin to envision the things which well reduce them, and the organism is finally said to wish.”
—William Gass (b. 1924)
