- 56 billion dollars – 24,000 deaths – 2.5 million disabiling injuries related to a sleep-type deprivation
- Exxon valdez, challanger, chyrnobel linked to sleep deprivation- at least partially
- Data has shown that in the Spring (when people lose an hour of sleep) there were 8% more traffic accidents on the Monday immediately after daylight savings. Conversely, in the Fall (when people gain an hour of sleep), there were 8% fewer traffic accidents on the Monday immediately after daylight savings.
- Studies have also shown an increased risk of myocardial infarction in Spring immediately after daylight savings, and a decreased risk of myocardial infarction in the Fall immediately after daylight savings.
