With the rise in digital device use, more people are expressing concern about exposure to blue light.

While blue light is around us daily as part of sunlight, artificial sources of blue light from device screens are often adding hours of exposure after dusk. Experts recommend heavy users take periodic breaks from device screens by using the 20-20-20 rule, which is a 20-second break, every 20 minutes to look at something 20 feet away.

Dr. Bryce St. Clair, instructor in the Department of Ophthalmology at Johns Hopkins University, said the concern over blue light is exaggerated, but it can affect sleep in some people.

"Blue light, we know will signal your brain to stay more stimulated," St. Clair pointed out. "Some people will say when they are on a phone or on a laptop before bed, that they stay awake longer than usual. And we know there's evidence to suggest that it affects circadian rhythms mildly."

He added people who experience difficulty falling asleep should use the blue light blocker or night mode on their devices.

Some people experience symptoms of eye strain with long periods of screen time. St. Clair explained with device use there is some evidence of reduced blinking.

"There's anecdotal evidence to suggest that if you are somehow involved with blue light devices, that you blink less often than those who don't use blue light devices," St. Clair noted.

He used the example of a physical book, emphasizing readers will blink significantly more often compared to those reading on a device, which may cause irritation for people who already have dry eyes.

St. Clair stressed ultraviolet radiation from the sun is a primary concern. He advised the single best thing you can do for your eyes is to wear sunglasses outdoors.

"Why are sunglasses fantastic? One, anytime you're squinting because it's too bright outside. That is your eye's way of telling you that's too much light. Number two, it prevents UV radiation and UV damage to the lens of your eye which can cause cataracts, to the retina which can cause macular degeneration," St. Clair outlined.

He also stated sunglasses help protect the eyelids against skin cancer. He recommended polarized sunglasses with UVA and UVB protection.

The Medicaid and CHIP programs are vital to rural Missouri, according to a report that says reliance on this safety-net health coverage is much higher in small towns than in cities - especially for children.

The Georgetown University report says proposed federal cuts threaten rural communities, where nearly 41% of children rely on Medicaid, compared to 38% in metro areas.

Dr. Shanon Luke, a pediatrician at a Federally Qualified Health Center in rural Missouri, said her clinic is essential to a community where the nearest hospital is 45 minutes away.

"The clinic being open is incredibly important to these kids receiving healthcare," said Luke. "Having Medicaid allows them to come in for their well-child checks, and for us to do some monitoring and treating of things before they get to scary points."

The report says to stay afloat, many rural hospitals have already been forced to close less profitable units. In 2022, 52% eliminated their maternity wards, compared to 36% of urban hospitals.

The report also reveals disparities, with about 40% of American Indian and Alaska Native people more likely to live in non-metro areas without access to adequate healthcare.

Joan Alker is the executive director and co-founder of the Center for Children and Families at Georgetown University. She said Medicaid helps recipients through much-needed preventive care.

"People wind up sicker and then, they're in the emergency room," said Alker, "and children can't get their asthma inhalers and they miss school."

Statistics show Medicaid helps prevent medical debt, covers most nursing home residents, and funds a significant portion of births and maternal care - issues Dr. Luke said her patients are familiar with, firsthand.

"For our families, both financially and medically, as well as mentally," said Luke, "it's really important to know that they have that coverage."

Just over 24% of Missouri's population lives in rural areas.

This month is National Blood Donor Month, and blood donor groups are making sure people know the importance of giving blood.

Blood can't be manufactured, so people need to donate blood at their local blood bank. Nearly 400 people a day donate blood to the American Red Cross in the DMV metro area.

Bethany Bray Patterson, communications director of the National Capital and Greater Chesapeake Region of the American Red Cross, said donor blood is used in a variety of medical situations.

"Donated blood," said Patterson, "goes to people who are heading into surgery, fighting cancer, newborn babies in the NICU and people who are living with sickle cell disease and other chronic illnesses."

Patterson added that someone in the U.S. needs a life-saving blood transfusion every two seconds.

However, only 3% of eligible donors donate each year. According to America's Blood Centers, if just 1% more of Americans donated, blood shortages would be alleviated.

Patterson said the blood supply in the country is stable, but organizations like the Red Cross are also on the look out for universal donors.

"There is an increased need right now for type O blood donation, and platelet donations," said Patterson. "Type O blood is always in demand. It's often going out to hospitals faster than it's coming in through blood donation, because it is the universal blood type. It's used the most by hospitals."

Community Health Centers are stepping up to meet a critical need for dental care across Tennessee.

Dental visits at these clinics have increased by 19% and patient numbers have risen by nearly 16%, underscoring the importance of these services.

Libby Thurman, CEO of the Tennessee Primary Care Association, said the demand has grown, especially as more people have gained dental coverage through TennCare, the state's Medicaid program. Thurman explains TennCare did not cover dental services for adults until recently, although it did cover children.

"In 2023, the state expanded access to dental services under TennCare for adults," Thurman noted. "We have had some challenges keeping up with that demand, and that really stems from just making sure we have enough dentists to serve all of those patients."

In 2023, Community Health Centers in the state provided more than 79,000 dental visits to more than 35,000 patients. Across the state, 24 of the 30 health centers now offer dental health services.

Thurman stressed the importance of having access to dental care, since it is so closely tied to a person's overall health. She added the clinics integrate dental services into their broader mission of providing whole-person care.

"Dental care, aside from just oral health, actually has a lot of links to systemic health," Thurman explained. "It's linked to a lot of chronic disease management - so, if your oral health care is unmanaged, likely your chronic disease could be worsened."

Thurman emphasized Community Health Centers provide care to all, regardless of a person's insurance or income status. They also have a sliding-fee scale, so patients are often able to get dental care at a lower cost than they might find elsewhere.
