Exposure design 1. Overview of exposure to heat shock (HS; 45°C, 1 h) and subsequent simulated diving at 37°C. Standard conditions were in an incubator with 5% CO₂ in air, 100% humidity, and 37°C. Both heat shock and simulated diving were in an atmosphere of 20 kPa (0.20 bar) O₂ and 5 kPa (0.05 bar) CO₂ in He
