As a changing climate exposes Coloradans to more days of dangerously high temperatures, health experts are offering common-sense summer safety strategies that can help reduce the risk of injury or illness.

Tawnya Selby, a certified personal trainer at Loveland Planet Fitness, said summer is a great time to get outdoors. Whether you are digging in the garden or hiking up 14ers, make sure you are staying cool and drinking enough water.

"Because we're drier in Colorado, you get dehydrated faster. So drink four ounces of water per the 15 minutes that you are outdoors. So about 16 ounces an hour," she explained.

Experts report last summer was the hottest in more than 2,000 years in the Northern Hemisphere, and Colorado is expected to experience above-average heat in 2024.

Selby said wear a hat, sunglasses and clothes that can protect you from the sun's powerful rays at altitude. If your skin is exposed, use sunscreen. People with chronic health conditions and those aged 65 or older can be at greater risk. Signs of overheating can include headaches, nausea or dizziness.

Dr. Donna O'Shea with United Healthcare said it's especially important to keep an eye on kids. Because their internal cooling systems aren't fully developed, some symptoms may be missed. But she says getting children outside and away from screens is important for eye health.

"Children who spend most of their time on a smartphone or computer have an 80% higher risk of developing nearsightedness," she continued.

Children should always wear life jackets when in boats or near bodies of water, but keep in mind that flotation devices are not a substitute for adult supervision. Selby said it's also a good idea to check with your physician if you feel like this is the year for a bucket-list adventure, such as tackling the rim-to-rim hike across the Grand Canyon.

"And if you need to work up to that, then come into the gym and work with a trainer. And we will help you get to that fitness level that you need to be at to go do your activity that you want to do," Selby explained.

Florida's new law banning fluoride in public water systems has drawn sharp criticism from dental professionals, who cite decades of evidence supporting its safety and effectiveness in preventing tooth decay.

Dr. Jeff Ottley, president of the Florida Dental Association, warned that the change will lead to a rise in cavities, particularly among children and underserved populations.

"Over the next two to three years, we will see an increase in the number of cavities, particularly in children and older adults who take multiple medications, which cause dry mouth," he said. "Those older adults will start getting cavities along the roof surfaces of their teeth and under existing restorations, like crowns and fillings."

Backers of the ban, including libertarian groups and some GOP legislators, have argued that "fluoride is a choice" and have recommended topical treatments, such as toothpaste, over what they claimed to be "mass medication."

Ottley stressed that fluoride occurs naturally in water, and the ban eliminates adjustments that allow cities to reach optimal levels for dental health.

He also predicted severe consequences, especially for Florida's Medicaid system and rural communities.

"The Medicaid system in Florida already has the lowest reimbursement rate across the country," he said, "and so you're going to have an influx in the number of kids looking, and parents looking to treat their kids who are on Medicaid, and the providers just aren't going to be there."

Ottley warned that higher Medicaid payments will be needed to attract dental-care providers, which he said could lead to ballooning costs.

His interim advice for parents: Seek prescription fluoride vitamins, and everyone should maintain rigorous brushing and flossing routines, cut their sugar intake and avoid post-brushing snacks before bed.

California lawmakers are considering a bill to ease regulations on birth centers at a time when maternity wards are closing in many counties. Assembly Bill 55 would streamline the licensure process, which allows a birth center to accept Medi-Cal, making midwifery care available to low-income families.

Sandra Poole, health policy advocate with the Western Center on Law and Poverty, said the bill would also no longer require a birthing center to be within 30 minutes of a hospital but instead rely on a transfer plan to address potential emergencies.

"Of course, if you're in an area where the labor and delivery has closed, that's going to be impossible," she explained. "There are 12 counties in the State of California that have absolutely no labor and delivery wards at all in the county."

Birth centers are non-hospital, homelike facilities for low-risk pregnancies. At least 40% of California's birth centers have closed since 2020, and just four of the 37 remaining centers are licensed, because the current licensing process is unnecessarily burdensome, according to a study published today by the Western Center on Law and Poverty, in partnership with the California Black Women's Health Project and the Black Women for Wellness Action Project.

The study also surveyed patients on the merits of birth centers. Holly Drayton is a mother and former doula from the Santa Barbara area.

"For people to have that option would really give them the opportunity to choose the birth that they want in an environment where they do feel comfortable to labor in the way that they're supported, to make it the best possible outcome," Drayton said.

Sarah Archer, a mother who supports birth centers, said they are an important part of the state's health care system, and are proved to reduce pre-term births.

"People deserve choices in the way they want to give birth, not just in a sterile hospital," she explained. "It's a very safe, very quiet, beautiful, serene environment versus a medical setting."

The bill has passed the State Assembly and is now before the Senate Health Committee.

The Illinois Department of Public Health said the first positive test for West Nile virus in 2025 has been detected in Winnebago County near Rockford.

Health officials warned people in the infected area and elsewhere to take precautions to avoid the mosquito-borne disease, which is expected to spread across the state. Last year, Illinois reported 69 cases of West Nile, with 13 reported human deaths.

Sameer Vohra, director of the Illinois Department of Public Health, said evidence of the disease usually emerges this time of year.

"In Illinois, we typically see the first environmental positive test for West Nile in mid- to late May," Vohra explained. "Mosquitoes typically emerge in the spring and are active until the first hard frost of the year."

Vohra noted West Nile virus is an endemic disease in Illinois, meaning it is commonly found in the state. Public health officials are highlighting the importance of taking action to "Fight the Bite" during National Mosquito Control Awareness Week, which runs from June 18-24.

Vohra pointed out most people who are bitten by infected mosquitoes do not contract the disease but one in five will show symptoms ranging from mild discomfort to a serious and possibly fatal illness.

"Right now, there's no treatment for West Nile virus," Vohra emphasized. "But supportive care is really important, especially if you're developing symptoms or you're that one of 150 people that can develop severe illness."

Public health officials have advised Illinoisians to wear long sleeves and pants outdoors, use Environmental Protection Agency-approved insect repellent and stay indoors during peak mosquito hours at dawn and dusk. They also recommend trying to keep mosquitoes from breeding.

"One way to do that is to dump any standing water," Vohra advised. "Examples of that include flowerpots, children's toys, pet bowls, bird baths, buckets, used tires, abandoned swimming pools, any place where you can get standing water."
