Sunday marks the start of Daylight Saving Time. Clocks “spring ahead” one hour at 2 a.m.

AAA says this time can be particularly dangerous for drivers due to less sleep.

The University of Colorado Boulder reports that deadly crashes rise 6% in the week following the time switch.

AAA is offering suggestions to stay safe during the time change. The agency suggests that drivers should get at least seven hours of sleep per night. Avoid heavy meals, alcohol or drugs before driving and consider traveling with an alert passenger so each can take turns driving.

Psychologists say that this shift in time can also lead to a rise in cardiovascular events and impact moods.

They say the key is to adjust one’s bedtime and wake-up time. Go to bed 15 to 20 minutes earlier and wake up 15 to 20 minutes sooner.

Maximizing light exposure in the morning is also key. Psychologists say to open the blinds and go for a walk outside, avoid mid-day naps and don't compensate by over-caffeinating.
