Although year-round daylight saving time is popular with outdoor enthusiasts, people who like to party and those who like to sell things to them, standard time is significantly better for most people, said Horacio de la Iglesia, a professor of biology at the University of Washington. His work on sleep cycles contributed to Seattle Public Schools decision to start school later for middle and high school students.
On Seattle’s shortest day, the sun rises at around 8 a.m. and sets just after 4 p.m. If Washington switched to year-round DST, the sun would rise at 9 a.m. and set at 5 p.m. that day in Seattle.
“You may think that the extra hour of evening light we gain with DST is good for you,” he explained. “But research shows that the hour of morning light we miss out on under DST is unhealthy for your body and mind.”
Human sleep patterns prefer to be in sync with “solar time,” he said, and standard time is closer to true solar time.
De la Iglesia said that under DST — when the clock is artificially shifted an hour ahead — we are asking our brains and bodies to wake up an hour earlier than they are biologically prepared to do. Sleep and mood disorders would follow, he said

One of the big arguments is the deaths that occur around the DST shifts, how many will occur when people are out of whack in the morning?
We tried this in the ‘70s. It lasted 10 months.
Great example of something where there is minor, short term pain for pretty good long term benefit. I think most people don’t know what it means in practice to get rid DST changes.
