Your brain is basically running a night shift operation while you're unconscious. Clearing metabolic waste. Consolidating memories. Regulating hormones. Maintaining the electrical grid that keeps everything firing properly. ⁠ ⁠ And that electrical grid? It runs on sodium.⁠ ⁠ Salt water isn't some magic sleep potion. Most research focuses on what happens when sodium gets really low: night cramps, restlessness, frequent wake-ups. Classic case of: “We know what breaks the system, but optimization? Still figuring that one out.”⁠ ⁠ Will drinking salt water before bed fix your sleep if you're stressed, drinking caffeine at 4 PM, and doomscrolling until midnight? Probably not. Everyone’s different. But if you've got the basics dialed in and you're curious about optimizing sleep the same way you optimize performance... might be worth experimenting with.
