Activating Brown Fat
Cold exposure is a powerful activator of brown fat, which plays a crucial role in temperature regulation and metabolism.

Regular temperature changes, such as wearing cooling vests or spending time outdoors in cooler weather, can also contribute to increased brown fat levels.In this clip
