As the country braces for a major winter storm this weekend, heart health experts have shared warnings of the physical strain shoveling can take — particularly for older adults.

A 2025 Mayo Clinic review found that just 10 minutes of heavy snow shoveling can push the heart to about 97% of its maximum rate. Exposure to cold air was also found to increase blood pressure and reduce coronary blood flow.

While there isn’t an official age that’s “too old” to shovel, some cardiologists recommend that individuals over 45 should exercise more caution to lower their chances of a cardiac event.

When to take caution

“While there’s no strict age cutoff, generally above the age of mid 40s and above, we tend to be a little more cautious — particularly in people who are less active [without] regular exercise,” Dr. Navjot Kaur Sobti, M.D., an interventional cardiologist at Northwell’s Northern Westchester Hospital in Mount Kisco, New York, previously told Fox News Digital.

“Certainly in people who are above the age of 65 — and who have risk factors for heart disease, such as high blood pressure, high cholesterol, diabetes, obesity or sedentary lifestyle — we recommend being very, very cautious about shoveling snow,” she advised.

Dr. John Osborne, M.D., a practicing Texas cardiologist and volunteer for the American Heart Association, shared similar guidance for people older than 45, especially males over 65.

“Unless you are in good cardiovascular shape and condition, it may be a good idea to ask someone for help,” he said in an interview with Fox News Digital.

The impact of snow removal is especially concerning for those with existing cardiovascular risks and a history of heart attack or stroke, according to the cardiologist. “People with these characteristics and those who have had bypass surgery or coronary angioplasty simply should not be shoveling snow in any conditions,” he said.

Osbourne said he often sees cardiac episodes in people who are typically sedentary and sit at a computer most of the day with little or no exercise. 

“Then once or twice a year, they go out and try to shovel the driveway after a heavy snowfall, and that unexpected exertion can unfortunately lead to tragedy.”

Hidden strain

The stress that is placed on one’s heart while shoveling snow is similar to what occurs during a cardiac stress test, Sobti pointed out, and may even exceed it.

Cold temperatures can cause blood vessels to constrict and blood pressure to spike — which, coupled with existing hypertension and the exertion of lifting snow, can significantly tax the heart, she warned.

“It’s almost like an at-risk person is putting themselves through an unsupervised maximal exertion stress test without a cardiologist actively monitoring them,” Sobti told Fox News Digital.

In addition to the exertion of shoveling, frigid temperatures can also strain the heart. Recent research has shown that cold exposure accounts for nearly twice as many cardiovascular deaths as heat exposure, including heat exhaustion.

That study, published in the Annals of Internal Medicine last month, also found that those over age 65 had higher rates of temperature-related deaths.

“So the risk is very, very high,” Sobti cautioned. “It’s really that sudden rise in blood pressure coupled with the physical stress of snow shoveling itself.”

Safer shoveling tips

The cardiologist said it’s ideal to have someone else help with snow removal — but if you do choose to use a shovel, she recommends pacing yourself and using a “pushing or sweeping” motion instead of heavy lifting.

To protect against the cold, Sobti also recommends covering your mouth, nose and extremities, wearing a hat and gloves, and using extra caution in windy conditions.

Using an automated snow blower can still raise the heart rate — up to 120 beats per minute, compared to 170 while shoveling, the American Heart Association states on its website.

It is also important to be aware of any symptoms of a potential cardiac issue while shoveling, Sobti emphasized.

If a person starts to experience warning signs such as chest pain, shortness of breath, a racing heart or palpitations, those should not be ignored.

Even if the symptoms resolve after a few minutes, a person “could still be experiencing symptoms of a heart attack” and should call 911 for evaluation, Sobti said.

“It’s better really to be safe than sorry.”

Airfare could become cheaper due to people slimming down, a new theory suggests.

Analysts at Jeffries are predicting that the expanded use of GLP-1 obesity drugs may reduce fuel consumption, which could translate into lower costs for airplane tickets, as Fox Business has reported.

The Wall Street firm suggested that a 10% reduction in average passenger weight could lead to about a 2% savings in aircraft weight, 1.5% lower fuel costs and a 4% boost to earnings per share.

“A slimmer society = lower fuel consumption,” Jeffries reportedly wrote in a note to clients. “Airlines have a history of being vigilant around aircraft weight savings, from olives (pitless, of course) to paper stock.”

These predictions come as weight-loss drug options are growing and the first GLP-1 pill has hit the market, making the medication more accessible.

Gary Leff, a Texas-based travel industry expert and author of the blog “View From the Wing,” elaborated on this prediction in an interview with Fox News Digital.

“The heavier something is, the more fuel it burns,” he said. “If passengers weigh less, planes require less fuel to fly. If everyone went to the bathroom before they flew, they’d weigh less and burn less fuel, too.”

“So, if average passenger weight declines, then flying the same plane on the same route will cost the airline less to operate,” he went on. “And in the most contestable markets, that will bring down fares, too, as airlines compete for passengers.”

Leff suggested that this won’t be true in all markets. Where the “supply of flights is constrained,” like in major cities, these lower costs are more likely to benefit the airlines than the passengers, as “costs fall, but fares do not.”

From a clinical perspective, Dr. Krishna Vyas, a plastic surgeon in New York City, noted that under current conditions, the use of GLP-1 medications is “too limited, too uneven and too short-lived to meaningfully lower average passenger weight at a population level.”

“Most patients discontinue therapy within one to two years, and weight regain after stopping treatment is common, making durable, large-scale reductions in passenger mass unlikely,” he told Fox News Digital. “Even if modest fuel savings were realized, there is no evidence they would translate into lower ticket prices.”

“GLP-1 medications represent a significant medical advance for individual cardiometabolic health, but extending their benefits to speculative effects on airline economics goes beyond what current clinical and population data support,” Vyas continued.

“Until broader access, durable adherence and sustained population-level outcomes are demonstrated, cheaper airfare should be viewed as a theoretical possibility — not a predictable consequence — of weight-loss drug use.”

Dr. Peter Balazs, a hormone and weight loss specialist in New York and New Jersey, discussed how GLP-1s could potentially impact the in-flight experience.

“Patients on GLP-1s experience reduced cravings for carbohydrates and a heightened preference for protein and fats,” he said. “Airlines may need to reconsider in-flight menus to cater to this growing demographic, offering more high-protein, low-carb options.”

Balazs noted that weight-loss medications can lead to gastrointestinal side effects, including GERD, dyspepsia, nausea and vomiting.

“From a medical standpoint, I would suggest loading up on antiemetics (medications that prevent or relieve nausea and vomiting),” Balazs shared as advice to the airlines. “Furthermore, I would counsel patients not to initiate therapy or administer a first dose shortly before a flight to avoid severe side effects at altitude.”
