How Does Your Body Burn Calories?
Your body burns calories in 3 main ways:
- Through your basal metabolic rate (BMR)—the energy your body uses just to keep you alive
- Physical activity—anything from walking to intense exercise
- Thermogenesis—the heat your body creates while digesting food or responding to temperature changes.
Simply put, your body burns most of its calories just by keeping your heart beating, your lungs breathing, and your body functioning. While physical activity can boost your calorie burn, the environment, like heat or cold, plays a smaller role.
That means wearing a hoodie might make you feel warmer, but it doesn’t magically speed up your calorie-burning engine—it just makes you sweat more to cool down.

Hoodie can only keep you warm and sweat more
Does Wearing a Hoodie Really Affect Calorie Burning?
A common misconception is that sweating more means you’re burning more fat. In fact, sweating is just your body’s way of cooling down—it’s not a sign of calorie burn. When you sweat a lot, the weight you lose is mostly water, and as soon as you rehydrate, that weight comes right back.
In simple terms, fat burning comes from using stored energy, not from the amount of sweat you sweat. Wearing a hoodie may make you feel like you’re working harder, but it doesn’t increase the amount of calories your body uses.
So instead of focusing on sweat, it’s better to focus on regular exercise and a healthy diet to see real results.
Some Expert Opinions and Studies!
Many fitness experts agree that wearing a hoodie while exercising does not significantly increase the amount of calories burned. Dr. John Smith, a sports scientist, notes, “Although wearing multiple layers of clothing may make you sweat more, this does not translate to more calories burned; it is mainly water loss.”
Scientific studies support this view. A study published in the Journal of Applied Physiology found that exercising in heat can impair performance. In fact, body temperature can rise by 2 to 3°C (3.6-5.4°F) during heat stress, which increases cardiovascular strain but does not significantly enhance calorie expenditure.
Additionally, a study in the Physiological Journals highlighted that although heat stress during exercise increases body temperature and sweating, it does not lead to a significant increase in energy expenditure.
In short, the above studies demonstrate that while wearing a hoodie may make you sweat more, it does not significantly increase the amount of calories burned.
Focusing on intensity and duration of exercise, along with adequate hydration and temperature regulation, trust me, it will be more effective in enhancing exercise performance and energy expenditure.

3 Benefits of Wearing a Hoodie While Training
While a hoodie won’t help you burn more calories, it can still be a great workout companion (in some cases like in cold weather)
- Keeps you warm: Hoodie provides comfort and helps regulate body temperature in cold environments.
- Increases focus: Creates a psychological effect that makes you feel ready and “in the groove” for your workout.
- Offers protection: Protects you from cold air, wind, or other distractions, so you can focus on your fitness goals.
In the summer, I recommend not wearing a hoodie while working out. It can be extremely hot and uncomfortable, and there are even more serious risks involved.

Working out in a hoodie still has some benefits
Potential Risks of Wearing a Hoodie During Exercise
While hoodies can be great for some situations, there are some risks you should be aware of, especially if you’re a beginner:
- Overheat: Hoodies trap heat, of course, which can make you feel uncomfortably hot or even lead to heat exhaustion during intense workouts.
- Dehydrate: More sweating means more water loss, and if you’re not hydrated enough, this can make you feel tired or dizzy.
- Restrict movement: If your hoodie is too loose or bulky, it can hinder your workout, making it harder to move freely.
If you wear a hoodie for gym, watch out for symptoms like excessive sweating, dizziness, nausea, or feeling unusually weak—these could be signs of heat stress. To prevent it:
- Stay hydrated by drinking water before, during, and after your workout.
- Take breaks when needed, especially in warm conditions.
- Consider removing your hoodie if you start feeling overheated.
Remember, proper hydration is key to staying safe and performing well during exercise. After your workout, cool down with stretches or light activity to help your body recover and regulate its temperature. Remember, comfort and safety should always come first!

Some Expert Advices for Safe and Effective Hoodie Workouts
Wearing a hoodie during exercise can be useful in certain situations, but it’s important to know when and where it’s beneficial.
- If you’re working out in a cold environment or need to warm up your muscles before a workout, a hoodie can help you stay comfortable and cozy. However, avoid wearing one in hot or humid conditions, as it can cause overheating and dehydration.
- It’s wise to choose clothing that lets your body breathe and move freely, especially during intense workouts. Lightweight, moisture-wicking clothes are ideal for high-energy activities like running or strength training.
It might be a bit chilly at first, but after just a few warm-up exercises, you’ll feel warm again. This advice works well for running, whether you’re racing or running long distance. You don’t need a hoodie or thermal wear, all you need is willpower and discipline!
Remember, the key to long-term fitness success isn’t quick fixes like sweating more in a hoodie—it’s about building sustainable habits like regular exercise, proper nutrition, and staying hydrated. Focus on consistency, and the results will follow!

Wearing a hoodie is only beneficial before you start running
FAQs
1. Can wearing a hoodie while working out lead to muscle injury?
If the hoodie is too tight or bulky, it can restrict your movement, potentially leading to muscle strain or injury. Injuries will make all your previous workout efforts go to waste, so it’s best to find comfortable, well-fitting clothes to wear.
2. Are there any specific exercises where wearing a hoodie is more beneficial?
For activities like stretching, warming up, or low-intensity exercises in cool weather, a hoodie can help keep you warm and comfortable. However, for high-intensity exercises, it’s better to choose breathable clothing, or take off that hot hoodie.
3. What are the best clothes to wear when exercising outdoors in cold weather?
For cold-weather workouts, it’s best to wear layers of breathable, moisture-wicking clothing. Start with a moisture-wicking base layer, then a lightweight insulating layer, and finish with a weather-proof outer layer.
Final Words
In short, wearing a hoodie while exercising does not significantly increase the number of calories burned, as it mainly increases sweating due to the regulation of body temperature. Remember, instead of relying on quick fixes like wearing a hoodie, focus on regular exercise, proper nutrition, and staying hydrated for long-term results.
