Sodium Loss in Humid Heat
Sodium loss in humid heat remains high despite dripping sweat—replace salt in fluids and food on long muggy sessions, not water alone.
Sodium loss in humid heat stays high even when sweat drips feel constant—humidity slows evaporation but does not stop salt excretion. Heavy sweaters leave white residue on kit and need deliberate sodium in fluids and meals on long muggy sessions.
Sweat testing refines generic drink advice. Pair sodium with fluids; avoid chugging water alone for hours.
Common questions
-
Do you need less sodium when sweat drips more?
No—dripping sweat in humidity still carries sodium. Heavy sweaters need more replacement, not less, especially past ninety minutes.
