Yeah that’s just the nature of submariners. Baby oil and assless chaps

Hello, former submariner here! They keep it pretty cold on submarines for two reasons; 1. It’s harder to doze off on watch when you’re cold, and 2. People with hygiene issues aren’t as fragrant at lower temperatures.

The engine room is usually a lot warmer than the forward compartment for obvious reasons, but I hear this has been fixed on the Virginia class boats by beefing up the AC units.
