The warming months are bringing heat safety to mind for anyone who works outside or in a challenging hot environment. How bad is it going to get? And what can be done to make it easier on everyone? These are common questions that arise this time of year.
Humans have an incredible ability to adapt to varying environments, but adaptation to heat takes time and varies by individual. Acclimatization to heat can take from two to three weeks when done properly and risks the worker’s health and work site safety if not done properly.
Appropriate heat acclimatization is accomplished by increasing one’s core body temperature 1°C for an hour each day during the work period. If the job requires PPE, as most do, workers need to slowly add PPE each day to balance acclimatization – adding 20% of clothing and equipment each day until the full worksite PPE can be worn. It’s not easy to put a worker that is used to cooler climates into a hot environment and have productivity and well-being stay the same. While it takes time and understanding of proper techniques, simple acclimatization steps make for a better, more productive jobsite in hot conditions.
Beyond acclimatization, dealing with heat during work is a complex problem. That’s because heat adaptability depends on how efficient a person is at cooling him or herself, via sweat, and there are several things that can contribute to that:
- being older than 35;
- psoriasis, cardiovascular disease or diabetes;
- prescription drugs for a variety of illnesses;
- over-the-counter drugs; and
- nicotine and alcohol use.
Including all of that information in protective strategies can be a logistical challenge. Understanding the physiological functions can help inform what metrics to use for recognizing heat stress.
As a worker’s core body temperature rises, the primary mode of cooling off is through sweating. Blood flow is increased to the skin, water and electrolytes are expelled by the sweat glands, and the evaporation of sweat cools the body down. This process is very efficient, as long as evaporation can occur while activity level does not increase and adequate hydration occurs.
Once a worker starts sweating on the job site in the heat, she needs to be monitored to track her health vitals. Heart rate needs to increase during sweating in order to pump blood fast enough to get it to the skin to cool down. But muscles also require blood to get oxygen and other nutrients for proper function during work in the heat. This means the cardiovascular system has added strain because it must get blood everywhere it is needed.
If a worker is sweating and maintaining a steady workload, eventually that fluid loss from the sweat is going to be felt. Sweat loss will result in lower blood volume and pressure. In order to maintain physical activity for work and continue sweating to keep the body cool, the heart once again needs to beat faster.
Being able to monitor a worker’s heart rate, body temperature, sweat rate and knowing the intensity of their daily labor can provide the best insights to the individual’s health at any given time during warm working conditions for the onsite supervisor or health and safety officer. Allowing managers to give each worker breaks at the right time (when their individual body needs them), with water and shade, can keep everyone safe in the heat.
The cardiovascular system is not the only vital function that’s disrupted during hot work. The nervous system is also impacted, decreasing a worker’s ability to complete tasks as well as affecting cognitive ability. Similar to the cardiovascular system having to work harder in the heat, the nervous system also needs to work harder in order to accomplish the same muscle movement that happened without the added heat. An overtasked nervous system makes work-related tasks harder as well as making cognitive decision-making more difficult. A worker experiencing heat stress is forcing their heart to work harder while his muscles are challenged to continue work and their cognitive functions are dropping, which add up to a significant risk to the individual, the team, the project and the company.
Worker heat stress is a serious and complex problem. Current heat safety strategies, without the use of today’s new smart PPE health monitors, may be well intentioned but not as effective as they could be. Today, advanced monitoring of personal heat stress indicators is possible, helping workers and their supervisors more closely watch individual physiological indicators of heat stress such as heart rate, sweat rate and activity levels, making summertime jobsites safer and more productive.

Rapid deployment of life-saving smart PPE critical for hottest summer on record ahead
NEW YORK CITY (May 11, 2021) – In anticipation of what the U.S. National Weather Service and U.K. Met Office predict to be the hottest summer on record, Kenzen, makers of smart PPE that monitors the heat health of workers in hot and humid conditions, announced a new rental program for its wearable devices. The rental program is being launched to help companies of all sizes across many industries protect workers and maintain productivity during the 2021 summer working season.
Kenzen sells its solution as a system that includes wearable worker monitors, a worker alert app, a manager app for on-site supervisors to predict and prevent heat stress for individuals on the job, and a data analytics dashboard for corporate Environmental Health and Safety (EHS) leaders to track patterns and make improvements to their heat safety programs.
To allow companies of all sizes to quickly deploy the new technology, Kenzen is offering rental packages of 10, 20, and 50 devices. The Kenzen kit includes devices, armbands, device chargers, apps available for both iOS and Android phones, and packaging for easy returns at the end of the rental period.
Packages can be rented for a two-month period online at store.kenzen.com, where training videos provide instructions for use and deployment. Kenzen also provides a snapshot of workers’ risk level and alerts after the rental period, which can be used by companies to enhance their heat intervention techniques such as locations of shaded areas, hydration stations and ice baths, and PPE clothing selections.
Kenzen devices are worn by workers and contain sensors that monitor, in real-time, an individual’s physiological markers that trigger heat injury risks. The worker is warned of heat danger via a smartphone app that vibrates and gives next-step instructions, as well as vibrations on the device they are wearing. Managers have a corresponding app that alerts them when a worker needs an intervention to stop work, rest, and hydrate, and when it is safe to return to work.
“We’re on a mission to protect as many workers as possible from the hot and humid season ahead,” said Heidi Lehmann, Kenzen Co-Founder and Chief Commercial Officer. “Our goal is to have at least 5,000 devices in the field before temperatures peak – protecting construction workers, road pavers, agricultural teams, roofers, drivers, and anyone who works outdoors.” Lehmann adds that, for every 10-degree Fahrenheit increase in temperature, there is a 393- percent increase in hospitalizations for heat exposure. “Now companies of all sizes have the power to predict and prevent heat-related injuries and deaths while managing productivity at the same time.”
Optional add-ons to the rental packages include the EHS analytics dashboard and on-site consultation and training. The Kenzen device rental program is available globally.
The Kenzen solution integrates the company’s commitment to personal data privacy; only workers can view the details of their personal health information and safety managers and other EHS leaders only see what’s necessary to keep the workers safe.
Kenzen has deployed its award-winning heat monitors with workforces across the globe in domains such as construction, mining, field services, manufacturing, renewable energy, utility oil and gas, and transportation.
Founded in 2016, Kenzen is the premier physiological monitoring platform to keep workforces safe from heat, fatigue, and over-exertion on the job while providing data-driven insights to maintain productivity.

Heidi Lehmann is co-founder and chief commercialization officer of Kenzen.
Heidi Lehmann has built companies in New York, Silicon Valley and near Boston. Now, the serial entrepreneur is building Kenzen in Kansas City.
“There’s a lot of intellectual capital here around industrial technology that you’re going to be hard-pressed to find in other places,” Lehmann said. “It just helps you gain depth in what you’re doing. … Because then there’s more of a roadmap, and you see which way you need to build and which route is the right way to proceed.”
Lehmann, co-founder and chief commercialization officer, wants to make Kenzen the premier physiological monitoring platform to protect workers from such safety threats as heat-related injuries and overexertion. Kenzen’s service includes a device workers wear to monitor physiological changes. It’s waterproof and ruggedized, and its design ensures safe operation in hazardous areas.
It’s all part of the industrial Internet of Things.
“It’s an absolutely enormous space, and I think, more and more, there’s this realization that there’s been a lot done to protect machines but not as much to protect workers.”
Lehmann chose Kansas City as the main headquarters for several reasons: affordability; a talent base being cultivated by companies like Garmin Ltd. and Cerner Corp.; and access to investors, domain expertise and potential customers.
The area also offers companies in adjacent markets, such as SafetyCulture, which helps customers monitor and audit measures to increase workplace safety. The two have compared notes, such as trends they’re seeing. A rising tide lifts all boats, Lehmann said.
More than just housing innovative companies, Kansas City backs them. To date, Kenzen has raised about $10 million, with its biggest concentration of investors in Kansas City. Two early investors, Women’s Capital Connection and Mid-America Angels, spurred additional links to area investors.
KCRise Fund, a locally focused venture capital fund, introduced Kenzen to prospective customers, including two that are in serious discussions. The startup’s local office is inside the headquarters of VC fund Royal Street Ventures. Lehmann can easily walk across the hall for advice.
Another local investor is Examinetics Inc., an occupational health screening and testing company. Examinetics promotes Kenzen’s offering to its base of 3,000-plus clients in more than 15,000 locations. Kenzen gains access to an extensive network of customer relationships and accelerates its ability to scale.
As Kenzen enters its Series A funding round, Lehmann knows the company can count on area investors to make warm introductions.
“We have investors and partners that we couldn’t have accessed in other places. I can’t think of a better place to be based.”
What it does: Developed predictive physiological monitoring software and a wearable device designed to keep workforces safe from heat, fatigue and overexertion
Locations: Dual headquarters in Kansas City and New York City
The outlook: Kenzen sits in the Internet of Things category, which is expected to grow from $726 billion in 2019 to $1.1 trillion by 2023. Kenzen has customers worldwide and expects its Examinetics partnership will help it reach the “next phase of growth.”
KENZEN LAUNCHES DATA DASHBOARD THAT ANALYZES SAFETY AND PRODUCTIVITY OF WORKERS IN HOT AND HUMID CONDITIONS
NEW YORK CITY (March 23, 2021) – Kenzen has launched a data and analytics dashboard, the latest component of its smart PPE connected worker solution. The dashboard captures workers’ core body temperature (the greatest predictor of heat stress and illness), productivity, and microclimates caused by clothing under hot and humid working conditions.
Environmental Health and Safety (EHS) managers and company leaders can now have a data-driven overview of work sites, both real time and retrospectively, to evaluate heat risk information by location and job role. The analysis consists of tens of thousands of data points collected per worker per day from the Kenzen wearable which tracks physiological factors including core temperature and heart rate. The Kenzen system uniquely enables companies to identify and address challenges and opportunities related to work in hot and humid conditions. The information allows them to manage risk and improve processes to keep workers safer and more productive.
Last year, Kenzen unveiled the monitoring device and its complimentary mobile app that alerts workers when they are at risk of heat stress and illness and when to stop work, rest, and return to work safely. The hardware and app work together to feed data to the real-time dashboard for supervisors to monitor their teams proactively and intervene when necessary.
Kenzen’s new analytics dashboard allows senior managers, who on average are responsible for 10 teams of 10 people each day, to dig deeper into the data and have a holistic view across worksites and teams. The dashboard provides insight into how various environments affect workers and uses the information to guide management in the implementation of changes to keep workers safer while optimizing productivity. Actionable feedback enables tailoring of work/rest schedules and identification of PPE clothing with the least impact on worker performance.
The complete Kenzen solution integrates the company’s commitment to personal data privacy; only workers can view the details of their personal health information and safety managers and other EHS leaders only see what’s necessary to keep the worker safe.
“The latest tool in the Kenzen connected worker solution comes just in time for a summer that’s expected to be one of the most extreme on record,” said Heidi Lehmann, Kenzen co-founder and chief commercial officer. Lehmann adds that, for every 10-degree Fahrenheit increase in temperature, there is a 393 percent increase in hospitalizations for heat exposure. “Now companies have the power to predict and prevent heat-related injuries and deaths and manage productivity at the same time.”
