Science is clear: a black T-shirt can keep you cooler than a white one (if you know how to use it)

A science explainer says a loose black T-shirt can feel no hotter than a white one, and sometimes even cooler.

Black absorbs more sunlight, but in roomy clothing hot air escapes by convection, reducing net heat gain.

A classic study in the Sinai Desert and Bedouin clothing suggest fit, weave, and airflow matter more than color alone.

For heat waves, breathable fabrics like linen or cotton and a looser fit may matter more than choosing white.
