                                According to a 2023 study published in *Nature*, researchers pinpointed specific brain neurons that trigger increased appetite in mammals exposed to cold, which helps explain why is it hungrier when cold. This phenomenon is a complex mix of ancient biology and modern psychology, driven by your body's innate need to produce heat and conserve energy.
