I can easily survive temps in the around 35-37 C with just a fan and ice.

Human and animal safety: High wet-bulb temperatures impair the body's ability to cool itself, increasing the risk of heatstroke and hyperthermia. A WBT above 35°C (95°F) is considered critical, beyond which even healthy individuals can survive only a few hours without cooling. Recent studies suggest dangerous conditions may occur at lower thresholds, around 31°C (87.8°F) in humid environments
