Health Considerations for Pennsylvania Residents
Medical research has revealed important health impacts of time changes in Pennsylvania. The spring forward transition is associated with a 7% increase in heart attacks during the first three days after the change. Car accidents also spike by approximately 7% on the Monday following the spring time change.
Agricultural Considerations
Farmers in Pennsylvania have historically had mixed feelings about DST. While the original justification for DST included giving farmers more daylight hours, modern farming practices rely heavily on the sun's position rather than clock time. Dairy farmers particularly note that cows don't adjust their biological clocks, creating temporary disruptions in milking schedules.
Historical Context
- Arizona and Hawaii are the only US states that don't observe DST statewide.
- The energy savings from DST are debated, with modern studies showing minimal impact.
- DST can affect health, with studies showing increased heart attacks and car accidents after the spring change.
Tips for Pennsylvania Residents
Use the extra evening daylight in summer for outdoor activities and vitamin D.
Remember that not all countries change on the same date - check international meeting times carefully.
Be extra cautious driving the Monday after the spring time change - accident rates increase.
Take advantage of the 'extra' hour in fall to catch up on sleep or tackle a project.
Why do we change clocks?
Daylight Saving Time was implemented to make better use of daylight during summer months, theoretically saving energy and providing more evening daylight for activities.
Do all states observe DST?
No, Hawaii and most of Arizona do not observe Daylight Saving Time. Some territories also opt out of the time change.
Is DST being eliminated?
While there have been various proposals to eliminate DST, as of 2027, most regions continue to observe the biannual time change.
