Heat, light and recovery experiments

1. Equipment & setup

   In December 2025, Johnson reported combining sauna with cooling. His post advised readers to hold a reusable ice pack between cotton boxers and shorts throughout the session. That was his advice, not an established fertility-protection method. His self-experiment did not establish whether sauna, cooling or their combination caused the changes he reported.

2. Conditions & changes

   In May 2025, he said nighttime cramps prompted him to measure sweat loss with a Gatorade Sweat Patch. He reported drinking 20 US fl oz before and 20 US fl oz after each session, each containing 350 mg sodium, 80 mg potassium and 24 mg magnesium. He described this as a Blueprint mixture developed from his own measurements; he owns Blueprint. These amounts describe his historical routine, not a hydration target for everyone.

3. The December account combines personal observations with advice to readers. Improvements in his measurements cannot establish which intervention caused them. The cooling and hydration details above were recorded in 2025; their continued use is not confirmed by the later session schedule.

The April morning routine and January article state 200°F for 20 minutes daily. A living protocol snapshot also prints 175°F; the dated April routine is treated as current.

The April 2026 routine says once daily. The January page said twice daily; the later source is treated as current.

Jan 2026 protocol: 3x/week; Apr 2026 morning post: 'occasionally'

Official page describes a finite 60-session course whose results he published; whether it is ongoing is not stated and the Apr 2026 morning post does not mention HBOT

1. He identifies Mitovit and describes lying down with a mask while the device cycles through stages. An earlier October 2025 account gave 32 minutes; the September 2026 reply supplies the newer session length.

The September 2026 reply does not give gas concentrations or session frequency. This is a supervised oxygen-exposure modality, distinct from a hyperbaric chamber.
