Yes, there are differences in cold exposure. As discussed with Dr. Susanna Søberg, there could be differences between men and women. Women, for instance, might have enough cold exposure with just nine minutes per week due to their increased metabolism in brown fat. However, this is still a topic of ongoing research.
When it comes to deliberate cold exposure, the effects can vary based on your mindset and your comfort level with the cold. If you dread the cold, your stress response will be greater, leading to a stronger adaptation response. Conversely, if you're comfortable in the cold, it might be harder to get the same level of adaptation response.
Remember, the key is deliberate cold exposure, meaning you're intentionally placing yourself in a cold environment to extract specific benefits.
