At 9pm, when most of London is settling into its evening routines Dr Christine Hall is often just beginning to prepare for the night ahead. While some of her working days finish at 6pm like many of us, others stretch deep into the early hours in A&E. Her schedule rarely follows a predictable rhythm. “In one word my sleep schedule is ‘chaotic’,” she says with a laugh. “It often depends on my shifts. It’s constantly changing – no two nights are the same.”
A typical night shift begins at 10pm and finishes at 8am. For the body, that reversal of day and night can feel like crossing time zones. “You essentially have jet lag,” she explains in a conversation with Alex Scott for British Vogue. “You need to make up the sleep you’ve lost in that time.”
Her days can vary just as much. “The finishing point of the day is always different,” she says. “I might be doing a night shift in A&E, or be in clinic from 10am to 6pm, or out at a dinner.” Navigating that unpredictability requires careful planning. “Planning is key,” she says. “Sleep is cumulative.”
As a doctor, she understands exactly how vital sleep is to long-term health. “As a medic, I know how important sleep is,” she says. “As I’ve gotten older, it takes me longer to recover.” Even short windows of rest, including naps, can make a difference. “If you can only get five hours, you’re always thinking about where you can make up the debt before the next shift.”
For someone navigating such an unpredictable routine, insight has become essential. She now incorporates technology to help her better understand her body’s rhythms. Wearable devices have quickly become part of her routine, offering insights that help her stay on top of even the busiest days.
“I think when you’re really busy with a full clinic, wearable tech isn’t intrusive,” she says. On days where she is more sedentary, “it gives you prompts to get up and move – it gives you a nudge.”
Her Samsung Galaxy Watch8 tracks everything from movement to sleep quality, while the Galaxy Ring monitors key wellness metrics continuously throughout the day and night. Together, they create a clearer picture of how well she has rested — and how prepared she might be for the day ahead. “The Galaxy Watch8 gives me a sleep score,” she says. “I’m quite competitive, so I’m always competing with myself to get a better score.”
Each morning, she checks the insights gathered overnight through the Samsung Health app. Accessed on the new Galaxy S26 Ultra, it acts as a central hub for the information collected by her wearable devices, bringing together sleep patterns, activity levels and daily insights in one place.
“Most mornings I wake up and have a look at it,” she says. “An idea of how much sleep I’ve had the night before gives me the insight I need to prepare for the night ahead.”
For someone who thrives on structure, the data is both motivating and reassuring. “I’m a numbers person,” she says. “So if I know I’ve had a rubbish sleep, the phone and the watch are going to give me hints on when to start winding down – and ultimately when to go to bed.”
Despite the demands of her job, she still prioritises small habits that help protect her sleep. “I try to accept that I can’t do everything,” she says. “But sleep is important.” Her evening routine is simple but intentional: no caffeine after 4pm and a warm shower before bed. If she’s not working a night shift, she aims to begin winding down early. “Our bodies are programmed to sleep when it’s dark,” she explains. “So if I’m not doing a night shift, I try to relax by watching something mundane and avoiding caffeine.”
She also creates an environment designed for rest. “It’s about preparing your body for sleep,” she says. “I have blackout curtains. And silence!”
The Samsung Galaxy S26 Ultra also includes a feature she particularly appreciates in the busy environments she works in: a built-in privacy display that ensures sensitive information remains visible only to her. “The privacy function makes the screen look normal to me, but I’m the only one who can see it.”
For someone balancing hospital shifts, clinic appointments and life beyond work, the ability to access meaningful health insights throughout the day makes staying on top of her wellbeing far easier.“When I’m really busy, my health isn’t always my top priority,” she admits. “So wearable tech helps provide support.”
She believes the potential of this technology is only just beginning. “As a medic,” she says, “I’m excited to see what comes next.”
