Due to a specific eye condition, I require a 70% humidity environment with zero air circulation (no AC permitted). My living space is entirely sealed. What techniques can I use to lower the temperature without creating drafts or drying out the air?

I appreciate everyone who provided suggestions; I now have several options to investigate. However, I am getting a lot of unsolicited medical tips for a serious illness I have lived with for 17 years, often treated as if it were a minor ailment. It is becoming very frustrating, so I am closing this thread. My thanks to those who actually focused on the cooling question!

In the short term, utilize an ultrasonic humidifier, which offers a minor cooling effect while adding moisture. To increase cooling without fans, place large tubs of ice around the room; this cools the air but also removes moisture, so you must run the humidifier simultaneously to maintain your levels.

For a permanent fix, consider installing radiant panels designed for temperature control. You can circulate chilled water through them using an external chiller unit located in a different area. While this setup is rare for American homes, it is standard in commercial buildings and avoids air movement.

Ideally, keep the water temperature slightly above the room’s dew point to prevent dripping. If you need more cooling, you can run the water colder and simply use the humidifier to replace any lost moisture. Expanding the surface area of the panels will also improve the cooling performance.
