How to manage type 1 diabetes during travel, work, and stress

Originally published on June 5, 2024

How to manage type 1 diabetes during constant travel starts with making invisible stress visible. In Episode 275 of the WHOOP Podcast, Kristen Holmes, Global Head of Human Performance, Principal Scientist at WHOOP, talks with Bambi Northwood-Blyth about overnight hypoglycemia, work strain, circadian disruption, and the small routines that help her stay steady.

Northwood-Blyth has modeled for Balenciaga, Chanel, Armani, Vogue, Elle, and Harper’s Bazaar, while living with type 1 diabetes since age 11. Her story is useful well beyond fashion. It shows how WHOOP can help you spot hidden strain, connect poor Recovery to blood sugar swings, and build repeatable habits when life rarely stays on schedule.

What does modeling actually demand from the body?

Modeling can create athlete-level strain, even when the work looks still from the outside. Northwood-Blyth explains that long set days, new environments, and constant social stimulation can drive her physiology much harder than she realized before wearing WHOOP and learning what Sleep, Recovery, and Strain measure.

That matters for anyone whose job blends time pressure, performance, and constant context switching. Northwood-Blyth says she used to leave work thinking she still needed a workout, only to find that a full set day had already placed a major load on her system. Holmes uses that example to make a larger point: strain is not only exercise. Mental activation, social stress, rushing, and unfamiliar settings all show up in the body.

Holmes highlights that people who perform well in busy environments often become comfortable in noise and chaos. Over time, that can shift from useful activation into chronic stress, which can lower heart rate variability and raise resting heart rate. For Northwood-Blyth, the first practical fix was simple. She started waking up 30 minutes earlier so the day did not begin in a rush.

As Northwood-Blyth tells Holmes, WHOOP changed how she interpreted a normal workday:

“One of the first times I wore it, I was running a bit late for work and I ran into set and I sat down in hair and makeup and about an hour in WHOOP detected an activity and it was a 12. I’d hit zone 5 and I was sitting in a chair.”

What you should take away

• Work strain can be real strain, even when you are sitting still.
• A high Strain day can come from social stress, rushing, travel, and constant stimulation, not only training.
• Starting the day without a frantic rush can lower stress before work even begins.

How did a severe overnight low change Northwood-Blyth’s health habits?

A near-miss hypoglycemic event forced Northwood-Blyth to treat structure as a safety tool, not a nice-to-have. After moving from a highly structured home life in Australia to an unstructured model apartment in New York, meal timing, sleep timing, and travel patterns became less predictable. Several years into that rhythm, the lack of consistency caught up with her.

Northwood-Blyth describes a 2019 event in Louisiana while shooting an Elle cover. She had flown from New York, dealt with a time change, skipped dinner, and went to bed jet-lagged. The result was a severe overnight low. That single night made it clear that her old habits were no longer safe for the life she was living.

The behavior changes were concrete. She started packing snacks, prioritizing dinner even when travel disrupted the day, and using a Dexcom continuous glucose monitor so other people could follow her blood glucose remotely. Those steps did not remove uncertainty, but they cut down the number of uncontrolled variables.

Northwood-Blyth puts the episode in stark terms:

“I’d been unconscious for 6 hours. I had 3 IVs and like 4 nurses there waking me up. So if I didn’t have someone come and wake me up, I wouldn’t really be here.”

What you should take away

• Severe overnight lows can be driven by stacked variables such as travel, missed meals, jet lag, and sleep disruption.
• Packing food ahead of time can be a safety habit, not only a convenience habit.
• Remote glucose sharing can add protection when you travel or sleep alone.

How can WHOOP help someone with type 1 diabetes find a stable baseline?

WHOOP helps by showing how Recovery, sleep, and daily strain connect to blood sugar patterns. Northwood-Blyth says her data taught her that a red Recovery often lines up with higher glucose, and that poor sleep, illness, and high blood sugar can reinforce each other.

That pushed her toward more deliberate tracking. In the WHOOP Journal, she logs patterns that matter for diabetes management, including nighttime lows and nighttime eating. She even used the behavior tag hot flashing sleep as a proxy for overnight hypoglycemia, because that was how those episodes felt in her body. Logging the behavior gave her a way to work backward from a rough night and ask what bedtime conditions made that outcome more likely.

One of the clearest findings was bedtime glucose. Northwood-Blyth says a number that looks normal during the day can be too low for a full night of sleep when you live with type 1 diabetes. For her, that changed the range she aims for before bed.

As she explains to Holmes:

“Now I’ve realized that’s about 140, whereas before I would be going to bed at say 90, which is great in the day but not for 6, 7 hours sleep ahead because your blood glucose is going to drop.”

That is an example of what good self-tracking looks like. It is not about chasing a generic perfect number. It is about finding the range that matches your physiology, your activity, and your daily pattern. WHOOP has explored similar self-experimentation in articles on nutrition and habit formation and on the 22 hours outside the gym that shape recovery.

What you should take away

• A red Recovery can line up with higher blood glucose and a more fatigued day.
• Bedtime glucose targets may need to differ from daytime targets when overnight lows are a risk.
• Tracking proxies such as nighttime eating or hot, restless sleep can reveal repeatable patterns.

What makes constant travel so hard on recovery and blood sugar?

Travel multiplies small disruptions until they become physiological stress. Northwood-Blyth spends only part of the year in New York, with additional months around the United States and Europe, plus many short trips that last one to three days. She says those short trips now hit harder than they did earlier in her career.

From there, Holmes broadens the frame. Travel is not only about fatigue. It also changes light exposure, movement, meal timing, and sleep timing, all of which can disturb circadian rhythm. Northwood-Blyth notices the contrast clearly when she returns to Australia in January. She spends more time outside, sees both sunrise and sunset, and often wakes up green for days in a row.

Her response is not fancy. She travels with repeatable rituals, including snacks, supplements, tea, and movement. She also has a rule for the first minutes after landing: do not lie down first. Put on sneakers, get outside, and start moving. That light exposure and movement can help her blood sugar come down and can make the new environment feel more familiar, more quickly.

Northwood-Blyth describes the rule like this:

“Before I even let myself go in a hotel room, it’s just like, put the sneakers on, get out the door. It was kind of this 2-minute theory. All you have to do is 2 minutes.”

That same idea appears across other WHOOP stories about sleep and recovery under pressure. The point is not a perfect travel day. The point is reducing the number of decisions you need to make when you are already depleted.

What you should take away

• Short trips can be harder than long stays because the body never fully settles into one routine.
• Light exposure, walking, and familiar rituals can reduce the shock of travel.
• A tiny action after landing can prevent a travel day from turning into a lost evening and a poor night of sleep.

How did Northwood-Blyth turn daily diabetes management into a business idea?

A health routine became a product idea when Northwood-Blyth realized the food she needed did not really exist in the form she wanted. During the slowdown that came with COVID, she returned to Australia, completed a business degree with a major in social entrepreneurship, and spent more time making portable foods that fit the demands of type 1 diabetes.

That work became a snack company designed for people with type 1 diabetes. The thinking came straight from lived experience. She wanted snacks she could use on the move, in the middle of travel, and in the narrow margins where blood sugar can swing quickly.

Her food observations are practical. Sauces and dressings can cause bigger spikes than the main dish suggests. Juicing can remove fiber and change the glucose response. Even cooking method matters for her. She finds steamed sweet potato easier on blood sugar than roasted sweet potato, which fits her broader preference for foods closer to their original state.

Northwood-Blyth also explains why mornings can be tricky. She describes the dawn phenomenon, where hormones such as cortisol and growth hormone push the liver to release glucose as the body wakes up. For her, even black coffee could extend that rise, so she changed the structure of the morning instead of forcing a fix with more insulin.

As she tells Holmes:

“There’s this thing in the morning called the dawn phenomenon where your body, when you’re waking up, produces hormones such as cortisol and growth hormone, which tells the liver to produce glucose to help you wake up.”

What you should take away

• The best nutrition strategy for type 1 diabetes is often highly personal and built through repeatable observation.
• Sauces, dressings, and cooking method can change glucose response more than people expect.
• Business ideas often come from routines you already had to build to keep yourself safe and steady.

The bottom line

• Invisible work stress can push Strain higher than people expect, even during hours that look physically inactive.
• Severe overnight hypoglycemia becomes more likely when travel, missed meals, jet lag, and sleep disruption stack together.
• WHOOP data can help connect poor Recovery with higher blood glucose, fatigue, and the added load of illness or stress.
• Bedtime glucose that feels normal during the day may still be too low for a full night of sleep in someone managing type 1 diabetes.
• Repeatable travel rituals, including snacks, walking, daylight, and familiar evening routines, can reduce the physiological cost of constant movement.
• Small actions, such as waking 30 minutes earlier or walking for two minutes after landing, can shift the whole day in a better direction.
• Logging proxy behaviors in WHOOP Journal can reveal patterns that are easy to miss in the moment.

Frequently asked questions about things discussed in this episode

How does WHOOP help you spot work stress that feels invisible?

WHOOP helps you spot invisible work stress by showing when heart rate, Strain, and Recovery shift during ordinary parts of the day. A set day, a rush across town, or hours of social stimulation can register as real physiological load even if the day does not include a formal workout.

What does WHOOP do for people trying to connect Recovery and blood sugar patterns?

WHOOP helps connect Recovery and blood sugar patterns by showing how poor sleep, high strain, and low readiness tend to cluster. Northwood-Blyth uses Recovery trends to notice when higher glucose and fatigue are likely to travel together.

How does WHOOP measure the strain of a long workday?

WHOOP measures the strain of a long workday through heart rate patterns and accumulated cardiovascular load across the day. That makes it easier to see when a demanding job has already taxed the body before you decide whether to add more training.

What does WHOOP Journal do for people tracking diabetes-related habits?

WHOOP Journal gives you a place to log behaviors that explain why a night or day looked the way it did. Northwood-Blyth uses behavior tracking to connect nighttime eating, hot restless sleep, and bedtime conditions with overnight lows.

How does WHOOP help with travel and circadian disruption?

WHOOP helps with travel and circadian disruption by showing how sleep timing, Recovery, and strain change when routines move. That feedback can guide simple adjustments such as earlier light exposure, more walking, and more consistent meals after flights.

What does WHOOP show about sleep timing when you travel often?

WHOOP shows that sleep timing matters because irregular bedtimes and frequent time shifts can lower Recovery even when total sleep opportunity looks adequate. Northwood-Blyth uses that feedback to protect bedtime routine and reduce the number of variables on travel days.

How does WHOOP help you test whether a routine actually works for you?

WHOOP helps you test routines by giving you a repeatable before-and-after view of sleep, Recovery, and strain. That kind of personal tracking is useful when a generic rule does not fit your physiology, schedule, or health condition.

For people balancing type 1 diabetes with constant travel and unpredictable work, WHOOP turns hidden strain into something you can actually plan around.
