While losing an hour of sleep this weekend may have been rough for some students, the coming weeks will provide more daylight to play Frisbee or read on the HUB lawn, all while bathing in even more sunlight.

This transition is easier on the body and mind than gaining an hour of sleep, said Mary Anne Knapp, clinical social worker and therapist at Penn State's Center for Counseling and Psychological Services.

"Overall, most people have more problems adjusting to earlier darkness," she said. "When there is no sunlight, it is a natural reaction to want to keep sleeping because there is no cue to wake up."

The change in seasons produces a shift in circadian rhythms -- the body's internal clock -- and higher melatonin production.

Melatonin is a sleep-related hormone secreted by the pineal gland and can cause symptoms of depression. It is produced in increased levels in the dark, according to the National Mental Health Association.

"Longer daylight typically results in more energy. It is sometimes difficult to settle down and sleep when it is still light out," Knapp said.

An increase in light may have some disadvantages. Those with a genetic disposition to bipolar disorder may experience an increase in symptoms, Knapp said.

Kim Wilhelm (junior-accounting and international business) was ready for the change.

"I can't wait until it stays light out until like 8 o'clock," she said. "I always have so much more energy during the summer months."

Knapp said this time of year does increase people's energy levels.

"They are not as worn out in the evening and feel better overall," Knapp said.
