Tree leaves are transforming to shades of green.

Flowers are blooming, grass growing—Michigan’s winter thaw is in full swing.

For thousands across the region, their allergies are, too.

Michigan’s peak allergy season generally is March through June, though many have reported early onset this year and with good reason.

Michigan experienced a mild winter. Mild winters can lead to an extended period for allergy symptoms.

“When the ground freezes over, the mold spores in the ground become inactivated and pollen allergens disappear,” said Mariel Benjamin, MD, assistant professor in the Division of Allergy and Clinical Immunology at Michigan Medicine.

Allergies that occur from late March through June usually are due to tree allergies, according to the Allergy & Asthma Center of Rochester in Oakland County, MI.

The good news is that most allergy sufferers often can find some relief with over-the-counter medications, nasal sprays and medicine.

Medicines and Line 5

“Michiganders might know Enbridge’s Line 5 in the Straits of Mackinac for providing propane, fuel and other essential energy,” said Enbridge’s Lauren Brown, an Enbridge community engagement advisor who’s based in the Upper Peninsula.

“I am not certain how many realize, though, that the crude oil and natural gas liquids Line 5 safely transports each day are essential to the production of medications, including those that help fight allergies,” said Brown.

“Springtime can bring allergies. I’ve noticed a lot of plants and trees in early bloom this year. Hoping that we all get through the pollen, so that we can really enjoy this special time!”

Once refined, the crude oil helps manufacture antihistamines, cough syrup, topical creams, salves and a host of other medicines. Product from Line 5 also is vital in the manufacturing of various packaging for medicines. Overall, the energy carried in Line 5 helps produce more than 6,000 products from eyeglasses to cell phones, stethoscopes, even kayaks and paddles. An untold number of consumers benefit from Line 5.

Healthy tips

Allergy sufferers also can manage symptoms with a few other tips:

  • Stay indoors as possible, especially during morning hours when tree pollen is at its peak.
  • Shower after being outside to remove pollen on your body.
  • Keep the windows closed at home or when in a vehicle.
  • Use washable curtains and area rugs.

“Each of us welcomes Michigan’s beautiful springtime,” said Brown.

“We simply want to enjoy it minus the itchy eyes and runny nose. I am glad we can follow some helpful tips to help curb the effects of allergies. It will add up to enjoying the outdoors, instead of suffering through spring.”
