Any extra calorie burn from exercising in cold or hot temps is minimal
Everyone has their preferences for how they want to exercise. Some like to wear layers and turn up the heat when pumping iron. Others like to run for miles, no matter how cold it is outside. But have you ever given any thought to how many calories you’re burning when it’s cold or hot — and if one burns more calories than the other?
Sports medicine physician Matthew Kampert, DO, shares how temperature can affect physical fitness and which temps are best for your workouts.
It takes a lot of energy — in the form of calories — to keep you alive. Even when you’re at rest, your body is constantly burning calories to do vital things like keep your heart beating.
It also takes calories to keep your core body temperature at about 98.6 degrees Fahrenheit (37 degrees Celsius). If your body gets too hot or too cold, it burns extra calories to get your core body temperature back to a healthy range. This process is called thermoregulation.
“The harder your muscles work, the more calories you burn,” says Dr. Kampert. “So, if you’re exercising in hotter or colder weather, your body has to work harder to regulate its temperature while you’re exercising.”
Both cold and hot weather can slightly increase the number of calories your body burns. But for most people, the difference is so small that it won’t have much impact on weight loss. It’s the workout itself that’s responsible for burning most of your calories.
Dr. Kampert explains how calorie burn changes in both cold and hot environments.
In colder environments, your body works to keep your core temperature from dropping. To do that, it first tries to conserve heat. If that’s not enough, it starts generating more heat. This process involves several different mechanisms, such as:
“Your muscles require energy every time they move, even when it’s an involuntary action like shivering,” explains Dr. Kampert. “You may burn a few extra calories when you’re cold, but the increase is small and isn’t enough to make exercising in cold weather a weight-loss strategy.”
Plus, without proper protection and enough layering, long-term exposure to cold weather could lead to injury and impact dexterity, flexibility and muscle strength.
Some people intentionally exercise in the heat or wear extra layers to make themselves sweat more, thinking it will help them burn more calories. But sweating doesn’t always equal an increase in calorie burn. It’s simply your body’s way of cooling itself down through thermoregulation.
When your body overheats, it works to lower your core temperature to healthy levels. It does this primarily through:
“Sweat evaporates more easily in hot, dry environments,” says Dr. Kampert. “In humid environments, the air is already saturated with water vapor, so it becomes harder for your body to cool itself down and harder to exercise.”
Trying to make yourself sweat more by exercising in extreme heat or wearing heavy clothing isn’t an effective weight-loss strategy. Instead, it can increase your risk of:
Working out in extreme temperatures poses significant risk for older adults, young children and others with a reduced ability to regulate body temperature.
Check in with your healthcare provider before exercising in cold or hot temps if you:
“If your goal is to burn more calories, the intensity, duration and consistency of your workout matter far more than the temperature of your surroundings,” stresses Dr. Kampert. “When exercising, focus on training safely and be prepared for inclement weather.”
Avoid wearing too many layers or accessories on your next cold run. Excess sweat can cool your body too quickly after exercising, making you feel colder. Instead, Dr. Kampert suggests wearing:
When it comes to the heat, stick to clothing that’s:
In either case, you want to stay hydrated and take things slow. If you feel dizzy or distressed, or if something doesn’t feel right, stop what you’re doing and head inside for recovery.
“Exercising in extreme temperatures increases the intensity of a workout, but it comes with its own set of risks and won’t increase how many calories you’re burning in any significant way,” reiterates Dr. Kampert. “If you’re looking to burn more calories, try progressing your workouts by increasing the amount of sets, reps or weight you’re lifting.”

When you’re pregnant, it’s important to eat a healthy diet that provides the nutrients you need. That helps keep you feeling your best and promotes healthy fetal development. But pregnancy also puts you at higher risk for foodborne illness. Some foods and drinks can increase your risk for pregnancy complications. Avoid high-mercury fish and processed meat, and go easy on salt and caffeine.
If you suffer from back pain, you’ve probably heard that strengthening your core can bring you some relief. But is this always true? And if so, how do you do it? We spoke with Cleveland Clinic physical therapist Patti Mariano, DPT, to find out.
When most people think about the core of the body they think of the abdominal or six-pack area just below the ribs. While the abdominal muscles are an important part of the core, we consider other areas important, too.
Your core includes:
Your core also includes the diaphragm and muscles of the pelvic floor. I also consider the gluteal muscles as core muscles.
Theoretically, if your muscles around the low back are weak, your body will rely more on passive structures, including ligaments — the tissue that connects bone to bone — as well as the spinal bones or discs, which lie between the spinal bones, for stability, which can cause pain.
But some studies have shown that specific core exercises are not any more beneficial than general exercise for low back pain. What we know is that exercise in general can help, and focusing on core muscles may provide some additional benefit.
Here are my top five:
For the plank exercises, start by holding them for 15 seconds to 30 seconds. For bird dog and scissors, try three sets of eight or 10 repetitions. For upward dog, do one set of 10 repetitions.
Any exercise performed incorrectly, whether it is core-strengthening or otherwise, has the potential to cause discomfort.
Twisting exercises or even incorrectly completing the exercises cited above can cause pain in the low back. But it’s highly unlikely that one repetition of an exercise will seriously harm your body, unless it’s an exercise using a very heavy weight.
The best way to keep your body safe is to listen to body cues such as pain during and immediately after an exercise, and the next day after exercising.
If any of the following is going on you should consult with your doctor:
Physical therapists train as musculoskeletal experts — they are the experts on muscles, bones and human movement. These professionals are the most qualified, aside from an orthopedic doctor, to assess back problems.
Since there are many factors that impact low back pain and many types of low back pain, it is a good idea to visit at least one time with a physical therapist for an evaluation and subsequent plan of care. This will give you an individually tailored plan with exercises that progress safely.
The idea of core strengthening, while beneficial, is just one piece of the low back pain puzzle.

Perhaps it’s unsurprising, given + + marketing, there’s an assumption health supplements are beneficial. They are not. Water & a balanced diet are the only health supplements we need (vast majority of cases). VAT on health supplements via @IrishTimes
