Health and Fitness Tracking Goes Mainstream

Since September, Jeanette Cajide has armed herself with an Elite heart-rate variability monitor. And a temperature-controlled mattress pad. And a Levels continuous glucose monitor. And an Oura Ring that also measures heart-rate variability along with resting heart rate, respiratory rate and temperature. “Yeah, I’m a little crazy on the devices,” says Ms. Cajide, director of strategy and operations at consulting firm Clareo.

She’s got good reason. After returning to competitive figure skating four years ago, she won a national championship. Then last September, she broke her leg while landing an Axel jump. Ms. Cajide, who is 44 years old, competes again in eight weeks—against many skaters half her age.

She is trying to override nearly two decades as a “sedentary adult,” working in tech and investment banking. “I’m trying to make up for lost time. It’s me against time,” she says. “The sensors and data allow me to optimize for getting the most mileage out of my body.”

There is no escaping the Quantified Self movement. Measuring biomarkers used to be the preoccupation of extreme athletes and extreme geeks. No more.

“I think the attitude is shifting. The seriousness of the pandemic has made people realize that gosh, isn’t it a good idea to have a sensor,” says Michael Snyder, chairman of the department of genetics at Stanford University’s School of Medicine, whose research, among other studies, indicates data from smart watches—alterations in heart rate, steps and sleep—can be used to detect Covid-19 as early as nine days before symptoms.

Until relatively recently, health-minded people were excited to track their steps and heart rate. Now they can perform their own urine and blood tests, conduct body-fat scans and monitor their emotions. Soon they may be able to monitor their rate of aging to take steps to slow it down. Rings, watches, patches and apps that monitor biomarkers have taken off, buoyed by a pandemic that alerted everyone to “underlying conditions” they might not be aware of.

Fitness and tech companies, already adroit marketers, jumped on the opportunity, intriguing people like Ms. Cajide. They “have created this persona of somebody who’s striving and they’ve done a really good job of it,” says Joe Vennare, co-founder of Fitt Insider, which produces a newsletter and podcast and invests in health, wellness and fitness. Fitness-tech startups raised $2.3 billion in 2020, 30% more than the year before, according to market-intelligence firm CB Insights.

People who track their data are constantly sharing online. One recently tweeted a graph comparing her heart rate: “me walking alone, hauling it: 140 bpm vs. me walking normal with my friend: <110 bpm.” Another boasted that since he began wearing a sleep-tracking device, he has averaged 8.25 hours of uninterrupted sleep a night. Another tweeted eight separate graphs of jagged green and blue lines with an ominous question: “Anyone have heart rate or respiratory rate peaks in the night that is DOUBLE their normal value? I don’t know if this is a medical problem or just the measuring device.”

Self-trackers often fixate on factors that might influence their performance. “It’s interesting to look at these things and learn about yourself. They can help you understand things you couldn’t unearth on your own,” says Chris Bailey, co-founder and chief technology officer of startup NatureQuant and an endurance mountain biker. He’s currently testing the Apollo Neuro, which isn’t a tracker, but is considered another bio-hacking device designed to increase heart-rate variability and optimize performance. Worn on the wrist or ankle, it is designed to reduce stress and recalibrate the nervous system using varying-frequency vibrations that can be programmed to make you more alert in boring meetings, focus better during cognitive or athletic activities and recover more quickly after physical exertion. Mr. Bailey’s early verdict: “It’s a little hard to tell. It helps with focus a little bit, maybe, but it’s certainly not something that 2Xes your performance.”

Individuals react differently to caffeine, pasta, late nights—almost everything. Last year, Whoop added a journal to its sleep-tracking app. In the journal, users can log more than 70 behaviors to see how, over time, they might affect sleep and performance. Activities include taking medication like Advil, drinking wine, reading before bed and having sex. In a podcast introducing the change, Whoop executives said users had frequently requested the sex-tracking feature. For some, sex can raise core body temperature which is counterproductive to sleep, the company explained, so you might want to take that into account the night before a big event.

As for alcohol: Not a good idea, according to Whoop. While many people think alcohol helps them sleep better, it disrupts the repair and recovery that is supposed to happen during slumber. It interferes with physically restorative slow-wave sleep and it “crushes” your mentally restorative REM sleep, Emily Capodilupo, now Whoop’s vice president data science and research, explained in a company podcast. It messes with your heart rate, suppresses recovery and increases the chance of injury.

When Ms. Cajide, the figure skater, heard about sleep tracking, she thought it was silly. “I don’t care what happens at night,’” she recalls thinking. Then she learned the significance of heart-rate variability—not heart rate, which is beats per minute—but the variance in the length of time between heart beats. HRV is a key indicator of how fit, recovered and ready you are to perform, and can be greatly affected by the quality of your sleep. “I went down the rabbit hole,” she says.

Now she wears a continuous glucose monitor—a patch attached to the underside of her arm. Its data displays on her phone, telling her what foods are spiking her glucose and how efficiently she is managing her energy. She programs the temperature of her mattress pad to gradually fall to 62 degrees in the middle of the night, to bring down core body temperature and thus positively influence her heart rate and HRV. So far it has gotten those metrics to their “best points mid-sleep ever,” she says.

She uses her Fitbit as an alarm clock because its vibration doesn’t spike her heart rate and scramble her metrics. Then she checks the data from her Oura Ring and compares it to that of her Elite HRV, “to make sure they’re giving me the same information.”

The information tells her how hard to train—whether she will attempt an Axel, the jump that resulted in her broken leg last fall. Her current program includes two. “On a good recovery day, I’m more comfortable taking risks,” she says. That is crucial because she has only recently recovered but competes again in just eight weeks.

Dr. Snyder at Stanford understands the obsessiveness. He wears four smart watches, two on each wrist, to figure out what variables are the best to measure and “also sometimes one will run out of batteries.” He believes Ms. Cajide’s kind of self-tracking is critical to the future of healthcare, saying, “If people really care about their own health, they are going to have to take charge.”

As a competitive rower in my long-ago prime I sometimes used a racing strategy called fly and die. Sprinting to an early lead often yielded a fast overall time, even if I couldn’t hold my torrid pace through the finish line.

Some professionals take a similar approach to their desk jobs, starting their workdays with a 5 a.m. to 9 a.m. shift. They are up before the sun—and, more important, before their co-workers—to get a jump on the workday and impress the boss.

Nothing screams go-getter like a predawn email! Getting stuff done early allows them to clock out midafternoon and still look like stars, even if their routines require Ben Franklin-esque sleep schedules and vats of caffeine.

Melissa O’Blenis rises by 4:30 a.m. for prayer and Peloton time before starting her job at the digital consulting firm Argano.

“I just love checking things off my list,” she says. “I need that focus time away from Teams messages, email notifications and text alerts.”

A mother with two sets of twins, O’Blenis, 48, often breaks for her kids’ afternoon sports without feeling guilty or judged. Colleagues jokingly call her Granny because her 9 p.m. bedtime makes the early starts possible. But Granny got the last laugh when she was promoted to a director-level role in March.

More than 90% of knowledge workers want to flex their hours, according to surveys by Slack’s Future Forum . In the pandemic many of us got in the habit of handling personal commitments during standard business hours, then catching up on work tasks later .

Now that the office battle is largely over, fighting a return to rigid, 9 a.m. to 5 p.m. schedules might be workers’ last stand. But managers complain about afternoon dead zones when employees are out of pocket.

The solution for more workers is starting sooner instead of finishing later. Workflow software maker Asana reports that 21.4% of users are logging on between 5 a.m. and 9 a.m. this year, up from 19.8% in 2021. About 12% of work tasks are completed before 9 a.m., the company says, compared with 10% before the pandemic.

Early-bird bosses

Gibran Washington and his basketball teammates at Hofstra University used to run at 6 a.m. He maintained his early wakeups while climbing the ranks in food-and-beverage management.

By 9 a.m. meetings, he had already exercised, meditated and put in a couple of hours of work.

“I always found myself more prepared than my colleagues who hadn’t had their first cup of coffee yet,” says Washington, 40, who doesn’t drink coffee. Now he is chief executive of Ethos Cannabis, a chain of 12 dispensaries in three states, and rises as early as ever.

Waking and working ahead of the pack is a common CEO habit, from Apple ’s Tim Cook to General Motors ’ Mary Barra . Even if your ambitions are less grand than the corner office, starting early could help you stand out for one simple reason: The boss is probably up, too, and taking notice.

Matt Kiger says being the first one into the office helped him catch his manager’s eye and advance after changing careers from education to media sales. He would set his alarm for 5 a.m., hop a train from Connecticut to New York and be at his workstation before 7.

“I thought, ‘What is it going to take to break through?’” he recalls. “‘It’s going to take being there when my boss comes in, already at my desk making phone calls.’”

Now a senior vice president for digital sales at Townsquare Media , Kiger, 47, says much of the daily communication among company leaders happens by text and phone from 6 a.m. to 8 a.m. It’s possible to succeed as a night owl, he says, but people who sleep in risk missing a window when many executives are awake and accessible. While some working parents can’t swing early-morning meetings, others like Kiger say they are the key to being present at kids’ after-school activities.

Getting the worm

Matt Sunshine—whose surname surely predestined him to be a morning person—wakes at 5:30 a.m. to read the news. Then he cycles or takes a Pilates class and is on his computer by 7.

Sunshine is CEO of the Center for Sales Strategy in Tampa, Fla., which helps healthcare, media and professional-services companies generate leads. He doesn’t expect his 55 employees to follow his schedule but says it becomes progressively harder to get his attention as the day goes on and his calendar fills up with meetings. He also tries to log off by 5:30 p.m. for family time, so working after hours won’t necessarily make an impression.

“If you want to get my attention, a good time to get me is first thing in the morning,” Sunshine, 55, says. “Because people know I’m an early riser, I think that does influence other people to do the same.”

Elvi Caperonis’s morning routine is next-level organised. Her alarm rings at 6 a.m. She goes for a run at 6:30. At 7 she showers and eats breakfast. At 7:30 she opens her laptop and sets a timer for 25 minutes. That’s her first block to focus on the most important task of the day before a five-minute break. She repeats the on-off work pattern throughout the day.

Caperonis, a technical program manager at Amazon , makes a daily to-do list with nine items. She rates one critical, three medium-level and five lower-priority. This helps her work efficiently and in the right order.

The 41-year-old works from home in Florida and often picks her daughter up from school at 2:30 p.m., freedoms she has preserved partly by being highly productive early in the day, she says. Much of her job involves identifying potential risks to a project’s success, and when she sends an early-morning alert it arrives really early for company leaders in the Pacific time zone.

“They appreciate having that information first thing when they open their email,” she says. “In my experience, leaders are also early birds.”

Health and Fitness Tracking Goes Mainstream

Self-tracking has moved beyond professional athletes and data geeks.

Working a regular day, even into the evening, is for mere mortals. Those out to impress start well before dawn.
