(CNN) – Get ready to spring ahead Saturday night.
The first Daylight Saving Time happened in 1918.
This was done during World War One, and it was done to conserve coal.
Even though setting your clock ahead one hour brings more sunshine to your day, it also comes at a cost.
One study shows losing that hour of sleep leads to a 25 percent uptick in heart attacks.
To avoid sleep deprivation, experts advise turning in 15 minutes earlier than you normally would on Saturday.
