This lake is eleven degrees Celsius, and I'm about to give it three minutes.
Three minutes submerged up to the shoulders in 10–12 °C water, two or three times per week. Triggers a large norepinephrine release, sharpens alertness for hours, and over weeks improves cold tolerance and mood scores. Start with shorter exposures and build up.
The protocol
| Duration | 3 min |
| Frequency | 2–3x/week |
| Water temp | 10–12 °C |
| Prerequisites | never alone · exit immediately if hyperventilating · never combine with alcohol |
Skip this if
- cardiovascular disease
- Raynaud syndrome
- pregnancy
- cold urticaria
- recent meal
The tub I keep outside holds the temperature between sessions, which is what makes this a protocol and not a dare.
Full transcript
Hi, I'm Mr. Age. This lake is eleven degrees Celsius, and I'm about to give it three minutes. Cold this sharp spikes norepinephrine and trains your nervous system to stay calm under stress. Three minutes, three times a week, and stress starts to feel smaller everywhere else too. Generate your prime age! More protocols like this on agegen.ai.
