In Hermantown, data centers roil local politics

On a chilly spring evening, Brea Schminski did what she’s been doing quite often recently: knocking on doors on a quiet street in Hermantown, Minn., asking people to sign a petition.

She stopped at Graham Sparkman's house just as he was making dinner.

“We're just trying to get signatures to petition for a charter commission. It would just provide more transparency for constituents,” she explained to him.

Sparkman is one of nearly 800 Hermantown residents who signed this petition that a judge approved earlier this week. In June, the judge will appoint seven Hermantown residents to form a charter commission. They’ll write a new charter for the city — essentially a city constitution — and the document will be put before voters to either approve or reject it on election day in November.

Schminski got involved because she opposes construction of Google’s hyperscale data center here, a project that’s facing significant pushback from local residents and environmental groups.

She's worried the data center will drain resources and disrupt the natural beauty of the area — concerns echoed in other communities where hyperscale data centers have been proposed.

But Schminski is also troubled that city officials signed non-disclosure agreements with the project's developer that prevented them from discussing certain details about the proposed data center publicly.

A city charter could prohibit city officials from signing future NDAs, she said.

“It gives more transparency. The NDAs could be off the table,” said Schminski. “I don't think they should be signing them for any project. [City officials are] there for us, so they shouldn't be hiding anything."

A lack of transparency

The proposed Hermantown data center is one of a dozen such hyperscale projects around Minnesota. Two lawsuits have also been filed to try to prevent construction of the Hermantown data center from moving forward.

And earlier this month, opponents in the community earned at least a short-term win when the city council delayed a decision on whether to provide Google with a $80 million tax break in exchange for building the $2 billion facility.

The Hermantown project still needs to clear other hurdles, including environmental review and additional permits.

But some residents are thinking beyond the potential construction of the data center about how to improve the openness and transparency of local government.

And that includes Greg Rosenberg. He led the petition effort. As a cybersecurity expert, he uses artificial intelligence often, which is what the data center would empower, and he's not opposed to data centers either.

But he is opposed to the discrete way the project was initially planned and how Hermantown residents eventually learned about the proposed data center.

“Most people found out not from the city but through these random articles and people talking to one another,” he said. “It became clear very early on that there was some level of opacity with this stuff."

Rosenberg quickly discovered that Hermantown's current governance structure gives residents little recourse.

“We don't have provisions for recall. There's no ability to put something on the ballot, like a referendum. There really were no ethical requirements like conflicts of interest or disclosure,” he said.

He said depending on how it’s written, a city charter could change all of that.

Taking constituent concerns seriously

Hermantown officials declined interview requests for this story, and data center tenant Google stopped responding to inquiries from MPR News after previously saying they would make someone available for an interview.

But city officials refute the allegation that they have not been listening to constituent concerns.

“I've heard a lot of folks mentioning we're not listening. I can definitely tell you we are,” city council member Andy Hjelle told an overflowing audience at a recent meeting. “We’re getting all the information we can and trying to make the best educated decision that we can."

And while these meetings have drawn large crowds of opponents, they’ve drawn supporters, too.

For instance, trade groups support the project because of Google’s promised job creation; the company promises the project would create up to 2,000 construction jobs and 100 long-term jobs.

At a recent city council meeting, Jack Carlson, a Hermantown resident and president of the Duluth Building and Construction Trades Council, said that those jobs would allow construction workers to stay close to home rather than travel for work.

“The ability for the Duluth building trades [workers] to stay home and eat dinners with their family and attend the events they potentially would miss is an amazing opportunity,” he said.

Others point out the project could expand the city’s tax base and raise millions in funding for the local school district, and Google promises to pay the cost of the project’s infrastructure.

Running for city council

Resident Emma Richtman doesn’t buy those promises. She said she never really followed local politics — until she learned about the data center.

“I just was gob smacked at the size and scale of this data center that they wanted to put two and a half miles from my house in the middle of a rural residential area,” she said. “And it just immediately floored me that this cannot happen. So that's when I started attending city council meetings.”

Since then, she's talked to state lawmakers and she's poured over project documents. Now, Richtman is running for city council.

“If this goes through, this is going to impact my family's longevity and my neighbor's longevity and their health and well-being,” she said. “I'm finding my voice, because my voice and my neighbor's voices deserve to be heard."

  • Saunas and steam rooms use heat to improve circulation, support muscle recovery, and reduce stress.
  • Regular heat exposure may benefit heart health, mood, and inflammation, though more research is needed.
  • Different types of saunas and steam rooms offer similar benefits, so choosing one depends on personal preference and goals.

People have been using the heat therapy from saunas and steam rooms for centuries to improve well-being and promote relaxation. Not only do these tools support muscle recovery after an intense workout, but they also boost circulation and reduce stress.

What Happens to Your Body in a Sauna?

Regular sauna use can have a positive impact on your body. Short bursts of intense heat raise your skin and body temperature, which researchers have found triggers your brain to start regulating your temperature. This activates systems in your body that control your stress levels and your hormones. You may notice changes like an increased heart rate, improved blood flow to your skin, and sweating.

Sauna use causes blood vessels to widen and may, over time, support reduced inflammation and cellular stress responses—but it’s not a direct or immediate cure-all for cell damage or inflammation.

Some researchers believe that the stress from the high heat may also mimic exercise and could be useful for people with limited mobility. However, more research is needed to fully understand the health benefits.

The Three Main Types of Saunas, Explained

There are several different types of saunas, such as dry saunas, infrared saunas, and steam rooms. Here's what you need to know about each.

Dry Sauna (Traditional Sauna)

A traditional or dry sauna offers high heat and low humidity and is usually found in local gyms and spas. Typically, the air is dry with 10% to 20% humidity, and the room is heated to a high temperature of at least 176 degrees Fahrenheit, sometimes higher.

Steam Sauna

A steam room uses water vapor to create a warm, moisture-filled room with dense, misty air. For comfort, most steam rooms operate at a lower temperature than saunas, typically around 110 to 120 degrees Fahrenheit, but can feel warmer due to the humidity. Like saunas, you can find them at gyms and spas.

Infrared Sauna

These saunas are dry saunas that emit infrared light waves to heat the body directly and do not use water or humidity. They can run a wide range of temperatures, from 113 to 165 degrees Fahrenheit. These types of saunas are popular in wellness spaces or among those who practice “biohacking.”

Potential Health Benefits and Risks of Saunas

Regular use of saunas and steam rooms can support heart health, improve circulation, and boost muscle recovery, as heat therapy increases blood flow and reduces tension.

There’s also some limited evidence that it can rid your body of impurities and heavy metals. However, more research is needed to fully understand the health benefits of heat therapy. Heat therapy is not widely studied, particularly regarding steam rooms.

The available research is promising. Here are some ways you might benefit from using a sauna or steam room.

  • Boosts heart health: A long-term, 15-year study found that visiting a sauna two to three times a week lowered the risk of dying from heart disease by 25% compared with once per week. Meanwhile, using the sauna four to seven times a week decreased this risk by 77%.
  • Enhances exercise benefits: One study found that combining regular sauna use with regular exercise can improve heart health by lowering cholesterol and blood pressure.
  • Promotes longevity: Your lifespan could potentially be longer when you use a sauna regularly, according to a 2021 review of several large studies. Researchers found that sauna use can slow aging, largely due to its cognitive, heart, and muscle benefits.
  • Improves mood: Regular sauna users may experience less depression and anxiety, and can be a useful tool for people in high-stress jobs.

Who Shouldn't Use Saunas?

While there are a number of benefits to utilizing a sauna or a steam room, these tools are not right for everyone.

For instance, people with certain heart conditions or those who are heat-sensitive may experience more adverse reactions than benefits from heat therapy.

Overuse can also cause dehydration, muscle cramps, and electrolyte loss. Consult with a healthcare provider before using a sauna or steam room, especially if you have any underlying health concerns.

Is One Type Actually Better for You?

There is little research identifying which type of heat therapy is best for overall health and well-being. Instead, both have benefits and can help you achieve your wellness goals. Most of the well-supported benefits come from heat exposure itself, rather than from the specific sauna type.

When deciding between the two, choose the sauna or steam room based on which you have the most access to—you will benefit from either. However, if you have access to both a sauna and a steam room, use the one you prefer and are more likely to stick with in order to see long-term benefits.

If your goal is health (especially heart health), consistency matters far more than the type of sauna you pick.

Which Sauna Should You Choose Based on Your Goals?

If you are fortunate enough to have regular access to both a sauna and a steam room, then you can make a choice between the two based on your goals:

  • For skin concerns: A steam room. If you suffer from dry skin or want to open your pores, the moist heat can hydrate your skin, encourage detoxification, and boost skin health.
  • For detoxification: A dry or infrared sauna. Because saunas cause you to sweat, your body may flush out toxins and impurities. There’s also some evidence that using a sauna can help rid your body of heavy metals.
  • For improved circulation and heart health: A dry or infrared sauna. These can help dilate your blood vessels and improve blood flow. These changes, when done consistently, could benefit heart health.
  • For improved breathing: A steam room. Moist heat is effective at opening your airways. Some people find that saunas are helpful for conditions like asthma.
  • For relaxation: Any. Not only does the atmosphere of saunas help reduce stress levels, but it also can improve mood and overall well-being.
  • For muscle recovery: Any. In a steam room, the moist heat will soothe sore muscles and joints and can be useful for conditions like arthritis or muscle stiffness. Meanwhile, dry or infrared saunas can promote relaxation, soothe muscle tension, and reduce pain and discomfort.
