January and February are typically the coldest months throughout most of the United States, increasing the risk of weather-related injuries and illnesses during this time.

An estimated across the country are injured due to falls each year, with the injury rate increasing significantly as temperatures drop and surfaces become icy. In addition, cold-related mortality rates in the U.S. are on the rise, having between 1999 and 2022.

While winter predictably brings an icy chill each year, NYITCOM-Arkansas Site DeanShane Speights, D.O., reminds us that the health burden of cold weather is still very real.

鈥淲hen we talk about extreme weather, whether it鈥檚 extremely hot or extremely cold, the body can have a hard time regulating itself during those periods,鈥� says Speights. 鈥淗ypothermia, frostbite, overexertion, and even falling are all major things we should be wary of this time of year.鈥�

For starters, choosing the right clothing can make a big difference. One tip that Speights shares: avoid 100 percent cotton.

鈥淐otton can hold moisture and actually make you colder, so try and stay away from that material and opt for something more like a polyester blend. You also want multiple layers, with the external layer being windproof, or waterproof in case there is drizzle, freezing rain, or snow,鈥� he explains.

He also emphasizes the importance of staying dry and, on days when the forecast calls for wet weather, bringing extra clothes, including a pair of dry shoes, socks, and gloves. Cold, wet feet and hands can lead to long-term injuries, including irreversible tissue damage.

鈥淯sually, the first signs of frostbite show up in your hands or your feet, as they鈥檙e farthest from your heart, making it harder for blood to reach them effectively. Be aware of any numbness in these and other areas and get indoors as soon as you start to experience symptoms,鈥� Speights says. 鈥淚ndividuals with chronic diseases, and on certain medications, can also have a higher risk of a cold-related illness鈥�.

Some signs of potential hypothermia, or that you may be getting too cold, include decreased heart rate, breathing, and difficulty concentrating or forming your thoughts,鈥� he adds. 鈥淎s the symptoms of hypothermia worsen, you are going to see some difficulty with cognition, making decisions, executive functions, and things like that.鈥�

Speights also recommends taking regular breaks and staying hydrated, including with warm liquids.

鈥淚t may sound strange to discuss hydration in the winter, as it tends to come up more in the hotter months, but it鈥檚 really important to stay hydrated in the cold as well. Take in plenty of water鈥攜our body uses liquids to maintain its core temperature and basic metabolism,鈥� he advises.

And, of course, Speights urges caution on slippery surfaces and while shoveling snow. In fact, after only two minutes of snow shoveling, one study found that participants鈥� heart rates exceeded of maximal heart rate, the level commonly expected during intense aerobic exercise. In combination with cold air, which can increase blood pressure and reduce coronary blood flow, shoveling in these conditions places a greater strain on the heart. This is especially true for sedentary individuals and those with underlying cardiovascular conditions.

鈥淣ow all of a sudden you鈥檙e working really hard to shovel that sidewalk, and you could put yourself in a position where you鈥檙e having chest pains, and that could lead to a cardiac event,鈥� says Speights. 鈥淧eople need to be aware that physical activity is harder on their bodies in cold weather.鈥�
