A recent study out of the University of California, Berkeley, found that a lack of sleep “impairs our basic social conscience, making us withdraw our desire and willingness to help other people” in addition to the other implications that come from not getting enough sleep like an increased risk of “cardiovascular disease, depression, diabetes, hypertension and overall mortality.” The study found that “charitable giving in the week after the beginning of Daylight Saving Time, when residents of most states “spring forward” and lose one hour of their day, dropped by 10% — a decrease not seen in states that do not change their clocks or when states return to standard time in the fall.” This is further evidence of the importance of getting proper sleep each night.
