Is Daylight Saving Time Killing People?

Daylight Saving Time begins on Sunday, March 11, 2018. Early that morning, most phones and computers will automatically shift an hour ahead. The interruption to our internal clocks literally kills people: incidents of heart attacks, strokes, and fatal car accidents all spike around the start of Daylight Saving Time each year. The annual ritual in which we trade an hour of morning light for evening brightness may seem like a harmless shift.
