Tokyo, Japan – Scientists at Waseda University have made groundbreaking strides in understanding how our brains interpret temperature differences, potentially revolutionizing how we manage thermal comfort in our environments.
Using electroencephalography (EEG), a technique that measures electrical activity in the brain, researchers have mapped out the activity of ten cortical regions in response to thermal stimuli. Surprisingly, the study revealed that both hot and cold sensations activate identical brain areas, but with a crucial difference: the brain employs unique electrical patterns to distinguish between the two.

This discovery sheds light on the complex neural processes behind our perception of temperature, which could have significant implications for health and comfort. Understanding these patterns allows for the development of more precise thermal comfort settings, moving beyond the often subjective “too hot” or “too cold” feedback to more objective measures.
The research suggests that better control of environmental temperatures could prevent health issues related to improper temperature settings, like the discomfort and potential health risks faced in overly air-conditioned offices or excessively heated homes.
These findings not only enhance our understanding of human physiology but also pave the way for smarter, more adaptive climate control systems in buildings and vehicles. As we dive deeper into the science of thermal perception, we’re one step closer to creating environments that are truly comfortable for everyone.
Key Points
- Waseda University researchers used EEG to study how the brain processes hot and cold sensations.
- 10 cortical regions are involved in temperature perception.
- Same brain areas are activated for both hot and cold, but with distinct electrical patterns.
- This could lead to improvements in thermal comfort settings, reducing guesswork in environments like offices.
- The findings promise health benefits by mitigating risks from inappropriate temperature control.
