Burning Calories in Cold or Hot Weather: A Complex Issue
In the realm of fitness and health, understanding how the body uses energy during workouts is a subject of considerable interest. One question that has sparked debate among scientists is whether it's better to workout in the heat or the cold for burning more calories.
The body's response to heat and cold during workouts can influence the number of calories burned. In cold environments, the body burns additional calories to generate heat and maintain its core temperature of 98.6 degrees Fahrenheit. This process, known as thermogenesis, is activated by exposure to cold and involves both shivering and non-shivering mechanisms [1][2].
A cold shower for 10 minutes, for instance, can burn approximately 100-200 extra calories by activating brown fat and inducing thermogenesis. A longer exposure, such as a 30-minute cold bath, may burn up to 300-500 additional calories due to complete body immersion and sustained cold exposure [1]. It's important to note that this calorie burn from cold exposure is independent of physical activity and supplements regular exercise and diet.
In contrast, exercising in hot conditions increases the body's efforts to cool itself (through sweating and heat dissipation), but it does not significantly increase calorie burning in the same way cold exposure does. The body regulates temperature primarily by heat release rather than heat generation during heat stress [3].
The debate over the optimal temperature for burning calories during workouts remains ongoing, with both cold and hot workout advocates presenting valid arguments. Cold workout advocates argue that the body uses extra calories to raise its temperature, while hot workout advocates believe that the metabolic cost of cooling the body burns extra calories.
It appears that both arguments are correct, as the body's need to both heat and cool during workouts burns calories in both processes. However, when it comes to calorie burning specifically, working out or exposing the body to cold environments results in more calories burned than exercising in hot conditions.
It's worth mentioning that exercise in heat requires careful hydration and heat illness prevention, not increased calorie burning. Additionally, both hot and cold therapies have distinct benefits for recovery but differ in metabolic impact [4][5].
In conclusion, incorporating cold environments into your workout routine could potentially help boost calorie burning. However, it's important to remember that a balanced diet and regular exercise remain the cornerstones of any effective weight loss strategy.

- Science has shown that cold exposure can stimulate thermogenesis, a process where the body burns additional calories to generate heat, which is a subject of interest in health-and-wellness and fitness-and-exercise.
- Engaging in a fitness routine combined with cold exposure could potentially aid in weight management, as exposure to cold environments independently burns extra calories beyond regular exercise and diet.
- Understanding the body's energy usage during workouts, particularly the additional calorie burning from cold exposure, can contribute significantly to science's ongoing pursuit of advanced weight-management strategies.
