A Calgary study that tracked nearly 15,000 slip-and-fall emergency room visits over 11 years found winter conditions were consistently the strongest predictor of ice-related ER visits, and the risk doesn't disappear the day after a storm. Research from within Canada shows the risk of falling stays elevated for up to seven days after a major snowstorm or ice event. For a senior living independently, that means winter isn't just one icy sidewalk to watch for. It's a weeks-long stretch where ordinary routines become higher-risk, often without anyone changing their day-to-day behaviour to account for it.

What the research actually shows about winter falls
Several independent Canadian studies point in the same direction, and the numbers are more specific than "be careful, it's icy out."
- A Calgary-based study of four adult hospitals over 11 years found 14,977 emergency department visits specifically coded for falls due to ice and snow, with winter months consistently the top predictor of these visits.
- Research on Montreal seniors found that freezing rain advisories were linked to a 20% increase in falls among older adults, with men 31% more likely to fall on those days specifically.
- A separate analysis found an 18% increase in fall-related hospitalizations within six days of a snowfall, and a lag effect where risk builds over the days following a winter storm rather than peaking only during the storm itself.
- In the Calgary data, women over 50 accounted for 25% more ice-and-snow-related ER visits than men, a pattern researchers linked to post-menopausal bone density loss, which makes fractures more likely to require hospitalization.
The common thread across all of this research: the danger window is longer than most people assume, and it often extends well past the day the snow actually falls.
Why the risk lingers for days, not hours
It's tempting to think of an icy sidewalk as a same-day hazard. The research says otherwise. Lingering ice, refreeze overnight, and snow that gets packed down into a hard, slick surface by foot traffic all keep conditions dangerous well after a storm has passed and the sun is out. That's part of why some studies found the sharpest rise in falls came three to seven days after a weather event, not during it. A senior who avoids going out during the storm itself may still be walking into elevated risk a week later, on a day that looks perfectly clear.
Why winter falls are more dangerous, not just more frequent
Winter falls also tend to carry worse outcomes than falls that happen indoors or in warmer months. A hard landing on concrete or ice produces more force than a fall onto carpet or grass, and cold temperatures cause blood vessels to constrict, which can worsen bleeding-related injuries and slow the body's response to trauma. Add in shorter daylight hours, a senior who may already be less willing to leave the house in the cold, and the fact that fewer neighbours or passersby are outside to notice a fall in progress, and winter turns a routine hazard into a genuinely different risk category.
Practical ways to lower the risk this winter
- Treat walkways proactively, not reactively. Salt or sand entryways and driveways before ice has a chance to form, especially after a freeze-thaw cycle, which is when refreeze tends to be worst.
- Reconsider footwear, not just outerwear. Winter boots with slip-resistant, deep-tread soles make a measurable difference on ice; smooth-soled boots or shoes are one of the most common contributors to a fall that didn't need to happen.
- Build in a buffer after storms. Given that elevated risk can persist for up to a week, it's worth checking in more often, or simply asking a parent to hold off on errands, for several days after a significant snowfall, not just the day it happens.
- Improve lighting and handrails outside. Shorter winter daylight means more walking is done in low light. A motion-sensor light at the door and secure handrails on any steps reduce risk without asking anyone to change their routine.
- Keep a way to call for help that doesn't require finding a phone. A fall on an icy driveway or sidewalk, away from the house, is exactly the scenario a wearable pendant or GPS watch is built for. A landline-based system inside the house doesn't help if the fall happens outside.
Why GPS-enabled devices matter more in winter specifically
Indoor fall detection systems cover the majority of falls that happen inside the home. But winter is the one season where a meaningful share of the highest-risk falls happen outside: on the driveway getting the mail, on the front steps, in a parking lot. A mobile system with GPS and fall detection is designed specifically for that gap, since it works anywhere there's cellular coverage rather than only within range of a home base station.
Frequently asked questions
How long does the risk of falling stay elevated after a snowstorm?
Canadian research has found the risk of falling can remain elevated for up to seven days after a major snowstorm or ice event, driven by lingering ice, refreeze, and packed snow rather than the storm itself.
Are winter falls actually more dangerous than falls at other times of year?
The injuries tend to be more severe. Hard surfaces like ice and concrete produce more impact force than falls indoors, and cold temperatures can worsen bleeding and slow the body's response, which is part of why winter fall-related hospitalizations tend to run longer.
Why are women over 50 more affected by winter falls, according to the research?
A Calgary study found women over 50 accounted for 25% more ice-and-snow-related ER visits than men, a pattern researchers attributed to post-menopausal bone density loss, which increases the likelihood that a fall results in a fracture serious enough to need hospital care.
Does a home medical alert system help with falls that happen outside, like on the driveway?
Not on its own. A home-based system is built for falls inside the range of the base unit. For falls that happen outside, in a driveway or parking lot, a GPS-enabled mobile system with fall detection is designed to work anywhere there's cellular coverage.
