It's that time of year again, when we time-shift into daylight-saving time. Be prepared to lose an hour from Saturday to Sunday, whether it be of sleep or productivity.

For some people the yawns and time crunch are a temporary nuisance. But health experts say a growing body of evidence shows that the disruption to our circadian rhythms and sleep can be bad for our health, leading to a higher immediate risk of heart attacks, strokes, atrial fibrillation and potentially car accidents.

As Sumathi Reddy reports in her Your Health column, many Americans would dearly love to scrap the whole thing. More states are passing legislation to stay on daylight-saving time permanently. The change can’t be made without congressional action, and even among those who want to shake the shift, there's little agreement on whether we should stay on saving time, or stick to standard time.

What are your thoughts on the impact of daylight-saving time on our health? Do you have any tips to share for managing the shift? Email me your comments, which may be edited before publication in the newsletter. Please be sure to include your name and location.

As cases of community spread of Covid-19 spring up in the U.S., government officials, employers and health care systems are scrambling to prepare for further spread. Hospitals have a message for people who think they may be infected with the novel coronavirus: Call first. Systems are setting up telemedicine services to minimize contact with potentially infectious patients and keep them out of busy waiting rooms. “We don’t want them coming into a doctor’s office or urgent care or emergency room to sit in a waiting room and potentially infect other patients,” said Robert Wyllie, chief of medical operations at the Cleveland Clinic.

Congress passed a spending package to address the virus. Washington state has emerged as the hardest-hit state so far, where all but one of the country's 11 deaths have occurred. Seattle-area companies and schools are implementing contingency plans to help contain the virus in the region. Officials in New York are tracking a ring of contacts around a single patient in Westchester county, ultimately quarantining around 1,000 people at home.
