As wildfires continue to burn in Canada, poor air quality is becoming a major concern for those living across the upper Midwest and Northeast, as wind directs the smoke into the U.S.

More than 830 wildfires were burning in Canada on Wednesday, along with more than a dozen in northern Minnesota, forcing mandatory evacuations. Some of the largest wildfires are located in west-central Ontario, where they have burned through dense forests, releasing massive amounts of smoke.

The wildfire smoke is also coinciding with a coast-to-coast extreme heat spell in the United States, with many places seeing temperatures in the high 90s and low 100s.

Wildfire smoke can negatively impact your health depending on proximity to the fire and the air quality index. Those with underlying conditions like asthma, COPD, heart disease, diabetes, chronic kidney disease or who are pregnant need to be extra cautious about breathing in wildfire smoke.

🥜 Cashew Allergy: Hidden Sources You May Not Expect

Did you know that cashews can be found in many foods—even when you don't see "cashews" listed on the front of the package?

Cashews are often used to add creaminess, texture, or flavor in foods such as:
✅ Vegan cheeses and dairy alternatives
✅ Pesto and creamy sauces
✅ Curries and stir-fry sauces
✅ Nut butters and trail mixes
✅ Granola and protein bars
✅ Plant-based desserts and ice cream

💡 Tips for staying safe:
• Always read the full ingredient list.
• Check for "Contains Tree Nuts (Cashew)" and "May contain" statements.
• Be extra cautious with bakery items, restaurant foods, and foods prepared in shared facilities.
• When dining out, let the restaurant know about your allergy and ask about ingredients and cross-contact.

A small amount of cashew can trigger a serious allergic reaction in some individuals. If you have a known cashew allergy, always carry your prescribed epinephrine auto-injector and know when to use it.

At Keystone Allergy & Asthma Center, we help children and adults with:
✔️ Food allergy evaluations
✔️ Allergy testing

☀️🌿 Summer heat can make allergies and asthma worse—but a few simple steps can help you stay comfortable and enjoy the season!

Here are some hot weather tips from Keystone Allergy:

✅ Check pollen and air quality forecasts before spending time outdoors.
✅ Keep windows closed and use air conditioning when possible.
✅ Shower and change clothes after being outside to remove pollen from your skin and hair.
✅ Stay hydrated—drinking plenty of water can help thin mucus and keep your airways comfortable.
✅ Wear sunglasses and a hat to keep pollen out of your eyes and hair.
✅ Use lightweight, breathable clothing to prevent overheating and skin irritation.
✅ Keep rescue inhalers and allergy medications with you, especially during outdoor activities.
✅ If you have eczema, rinse off sweat promptly and moisturize regularly to prevent flares.
✅ Don't forget your pets! Pollen can collect on fur and be brought indoors.
✅ Replace or clean home air filters regularly to improve indoor air quality.
✅ On poor air quality or high ozone days, consider moving exercise and activities indoors.

If allergies or asthma are interfering with your summer plans, we're here to help.

🩵 Infant & Toddler Anaphylaxis: It Doesn't Always Look Like You Think 🩵

Babies and toddlers can't always tell us when they're having an allergic reaction. In fact, anaphylaxis may present with subtle signs beyond hives or swelling.

👶 Watch for:
▪️ Sudden fussiness or inconsolable crying
▪️ Ear pulling, tongue thrusting, or excessive lip licking
▪️ Fast or noisy breathing, coughing, or a hoarse cry
▪️ Vomiting, back arching, or refusing to eat
▪️ Floppiness, unusual sleepiness, or changes in behavior

Trust your instincts—you know your child best. If you suspect anaphylaxis, give epinephrine immediately and call 911.

We created this infographic to help parents and caregivers recognize the unique signs of anaphylaxis in infants and toddlers because early recognition and treatment can save lives.
