Our sudden surge of winter weather is hitting the high country really hard. Some folks woke up to a foot of snow this morning. "When you have that big of a change in temperature, that drastic change, it means the body also has to adjust itself more quickly than normal," said Dr. Shad Marvasti, director of public health, prevention and health promotion with the University of Arizona College of Medicine – Phoenix.

Antibodies that may protect against COVID-19 in people who have previously had the virus declined over the summer, according to a new study that could throw doubt on the idea that a population can develop herd immunity. A University of Arizona Health Sciences Study that examined a sample of nearly 6,000 COVID-19 patients, showed that antibodies persist for months after infection, providing long-term immunity. “We clearly see high-quality antibodies still being produced five to seven months after SARS-CoV-2 infection,” said Deepta Bhattacharya, associate professor of immunobiology, at University of Arizona College of Medicine.

A new study from University of Arizona Health Sciences found that SARS-CoV-2 (the virus which causes COVID-19) may actually have a pain-diminishing effect on those it infects, particularly in the initial phase of infection. Dr. Rajesh Khanna, lead author and professor of pharmacology at the University of Arizona College of Medicine, talks about his research recently published in the journal PAIN.

While the days leading up to most presidential elections carry a certain frenzied, exhausted energy fueled by attack ads and nonstop robocalls, this election cycle has felt abnormally anxiety-inducing for many Americans. “We’re certainly in the middle of a perfect storm,” said Dr. Esther Sternberg, research director at the Andrew Weil Center for Integrative Medicine at the University of Arizona. Humans respond physiologically to stress — we sweat, our hearts race — and those responses, Sternberg said, are essential for our survival.

As people have adjusted their daytime rhythms to the pandemic, experts say they have also experienced changes in their sleep patterns.

While Arizona isn't seeing the surge or "second wave" of COVID-19 cases occurring in other states, public-health officials here are concerned cases could rise again. Epidemiologists say some rural regions of the state haven't fully recovered from the first wave and could be hit much harder a second time around. Dr. Daniel Derksen, director of the Center for Rural Health at the University of Arizona, said four rural Arizona counties have had double the per-capita number of coronavirus infections and deaths of the state's urban areas.
