Sun and Sleep [Abstract]

The summer solstice is upon us. At its peak, the sun rises at 5:07 AM and sets at 8:40 PM, giving this part of Vermont 15.6 hours of daylight. That contrasts with the scant 7.8 hours of daylight the winter solstice affords here. Summer's lingering twilight melts into soft evenings, unlike the cold, harsh intrusion of winter night. As someone with bipolar disorder, I celebrate the extended daylight because it helps my brain produce the happy-making neurotransmitters serotonin and dopamine. . . .
