Clothes

Neanderthals were likely able to survive in a similar range of temperatures to modern humans while sleeping: about 32 °C (90 °F) while naked in the open and windspeed 5.4 km/h (3.4 mph), or 27–28 °C (81–82 °F) while naked in an enclosed space. Since ambient temperatures were markedly lower than this—averaging, during the Eemian interglacial, 17.4 °C (63.3 °F) in July and 1 °C (34 °F) in January and dropping to as a low as −30 °C (−22 °F) on the coldest days—Danish physicist Bent Sørensen hypothesised that Neanderthals required tailored clothing capable of preventing airflow to the skin. Especially during extended periods of travelling (such as a hunting trip), tailored footwear completely enwrapping the feet may have been necessary.
