Sleep troubles may complicate the grieving process

 E-Mail Those who have persistent trouble sleeping may have an especially difficult grieving process after the death of a loved one, a new study co-authored by a University of Arizona researcher finds. Most people who lose a close friend or family member will experience sleep troubles as part of the grieving process, as the body and mind react to the stress of the event, said study co-author Mary-Frances O Connor, a professor in the UArizona Department of Psychology. But O Connor and her collaborators found that those who had persistent sleep challenges before losing someone were at higher risk for developing complicated grief after a loss. Complicated grief is characterized by a yearning for a lost loved one so intense and persistent that it disrupts a person s daily functioning. It occurs in 7-10% of bereaved people, O Connor said.

How a Smartphone App and Contact Tracing Helped Keep UArizona Open and Curb COVID-19 Spread

Chris Richards Since the University of Arizona launched Covid Watch Arizona – an anonymous COVID-19 exposure notification app – in August, the app has had relatively high download and usage rates, and university analysts estimate that it may have helped reduce the average number of people infected on campus by 12%. Joanna Masel That estimated 12% reduction in transmission matters. If you can get R(t) (the average number of people infected by a positive person) to drop from 1.06 to .94, that translates from exponential growth to exponential decline, said  Joanna Masel, a professor of in the UArizona Department of Ecology and Evolutionary Biology and a member of the university s BIO5 Institute. Masel led the development of the app s risk scoring component, as a member of the UArizona Covid Watch implementation team and a consultant for WeHealth, the company that distributes the app.
