Think about ink

Some areas of medicine fall into the category of “Experts know a lot about it and how to treat it.”

Others are more like “We’re still studying this, but be aware.”

Ink on items like receipts, food labels and kids’ toys falls into the latter category.

It all centers around a chemical called bisphenol S (BPS for short) that lurks on some of these items, says Jennifer Whitfill, APRN, a family nurse practitioner at OSF HealthCare. She says if BPS seeps into your body through the skin on a regular basis, you could be at increased risk for diabetes, issues with your reproductive and endocrine systems and other ailments.

So, what’s the level of concern?

Whitfill says more research is probably needed to get a full grasp of the risk. But it’s something to just be aware of and something to take simple steps to avoid.

“Don’t get a receipt if you don’t need it. Or have the store text or email it to you,” Whitfill says. “If you have to get a paper receipt, handle it for the least amount of time as possible. Experts say BPS can be absorbed into your skin within 10 seconds.”

Frequent handwashing can also help. But Whitfill cautions that hand sanitizer won’t do the trick.

“Do not use hand sanitizer before you get the receipt. The alcohol in hand sanitizer can actually make the BPS absorb into your skin quicker,” Whitfill says.

If you handle receipts regularly (such as a cashier), consider wearing gloves, and wash your hands during breaks.

“We do these things multiple times a week – get receipts, handle packaging – and don’t even think about it,” Whitfill says. “Just be aware that this risk exists.”

If you’re feeling unwell – whether you think it’s from BPS or not – and things aren’t getting better quickly, see a health care provider.

Planes, trains, automobiles…and your health (part one)

Summer means getaways to de-stress and make memories. But the last thing you want is to catch a cold or worse, especially if you’re halfway across the world where health care resources might be different or scarce.

It's not too late to make some quick preparations, says Jennifer Whitfill, APRN, a family nurse practitioner at OSF HealthCare.

Stop by the doctor’s office: Whitfill says if you haven’t seen your primary care provider for a physical exam in a while, make an appointment before vacation to address any lingering health issues. This could include getting vaccines depending on your health and where you’re going. Whitfill says typhoid fever (seen in southern Africa, Asia, Central America and South America), yellow fever (Africa), hepatitis A (remote or underdeveloped areas) and rabies are ailments to protect yourself against.
Stock up on over-the-counter medication.

“It’s important to be prepared,” for when these medications are needed, Whitfill says. “Consider packing Tylenol or ibuprofen, anti-allergy medicines like Claritin, Zyrtec and Benadryl. Dramamine is a good one for motion sickness or nausea. Some people reach out to their provider if they’re going on a cruise. There’s a prescription called a scopolamine patch that you can put behind your ear. It’s good for three days and helps offset motion sickness.

“Eyedrops are good if you have seasonal allergies. Over-the-counter saline or Pataday drops,” Whitfill adds. “Creams like hydrocortisone and triple antibiotic ointment are good to have.”

For outdoor trips like camping, essentials including a first aid kit, sunscreen and bug spray are must-haves, too. Know if you’re on a medication, such as certain acne creams and menstrual cycle medications, that makes you more prone to sunburn.

And regardless of what you pack, Whitfill says flyers should check the Transportation Security Administration guidelines about what can come on a plane. She says to leave medicines in their original packaging when preparing airport luggage.

Medicine, part two – before you go: You might hear travel bloggers say to boost your immune health before traveling to reduce your risk of catching something. Is the advice overblown?

Whitfill says no. She says elderberry, vitamin C and D and zinc are all good supplements to take before a trip. Start three to four weeks before departure, if you can. And if you have concerns about supplements interacting with prescription medication, talk to your provider.

It's not too late to make some quick preparations, says Jennifer Whitfill, APRN, a family nurse practitioner at OSF HealthCare.

Know your destination and what to do if something goes wrong.

“If you have a medical condition, have your medications with dosages on a list. Have your health care provider’s information on that same page. That way in case something happens, they know how to get ahold of the provider to ask questions,” Whitfill says. “Investigate where is the closest health care facility, whether that’s a hospital or an urgent care, in case you need care quickly.”

This is especially important, for example, for people with heart conditions who might require a complex level of care at a moment’s notice.

Consider travel insurance: It might not be needed for every trip, but it can give you some peace of mind.
Crowded areas: Train stations and airports are full of people from all walks of life, and it’s a safe bet that some of them are under the weather.

“Good hand hygiene is huge,” Whitfill says, especially after contacting high-touch areas like an escalator railing. “If you are immunocompromised or worried about catching something, you can always mask. Boost your immune system [prior to travel], and keep your distance [from others] as much as possible.”
Sleep: If you’re crossing multiple time zones, adjust your sleep a few days in advance to avoid exhaustion. Whitfill says if you’re traveling east, go to bed and wake up a few hours earlier each day. If you’re traveling west, go to bed and wake up a few hours later.

“Book a flight that lands early in the evening. After landing, try to remain awake until 10 p.m. local time. That helps adjust the body’s sleep cycle,” Whitfill explains. “Also practice good sleep hygiene. Drink plenty of fluids. When you’re flying, get up multiple times to keep blood flowing. Stay away from alcohol and caffeinated beverages.”
Food and drink: You might have heard claims from friends and family that the water in [insert location here] is dirty and unsafe. That might be a bit exaggerated, but when in doubt Whitfill says to use bottled water, even when brushing your teeth. And pack some medicine in case you get diarrhea (Imodium or Pepto Bismol) or constipation (probiotic or laxative).
