Is it true that spacesuits dissipate metabolic heat generated by astronauts using specific cooling systems?

Yes. Evidence confirms that spacesuits dissipate metabolic heat generated by astronauts through specific cooling systems, notably liquid cooling and ventilation garments (LCVGs) that circulate water.

The analysis

Papers [1], [5], [8], and [9] all explicitly discuss the use of thermal regulation systems—specifically liquid cooling and ventilation garments (LCVGs)—in spacesuits to remove metabolic heat generated by astronauts during extravehicular activities. No papers refute this mechanism, making the claim well-supported.
