Hydration Infrastructure for Aviation

Airlines optimise
everything — except
the one variable that
degrades every passenger.

At cruising altitude, cabin humidity falls to 10–20% — lower than the Sahara Desert. Stratolyte is the first altitude-engineered hydration protocol designed for aviation.

Problem

A physiological gap flying under the radar

Every aircraft is a controlled environment — temperature, pressure, airflow. Airlines have engineered almost everything. But cabin humidity at cruising altitude sits between 10–20%, and no airline manages its physiological consequences.


Passengers under-compensate. Crew operate under sustained strain. Water, juice, and sports drinks are not engineered for altitude. Fatigue and poor recovery have been normalised as a flight by-product — until now.

Solution

Hydration as deployable infrastructure

01
Pre-Flight
Prepare
Pre-load electrolytes before boarding. Prime the body before the cabin environment begins its work.
02
In-Flight
Maintain
Sustain hydration through dry cabin air. Integrated into existing cabin service workflows — no new hardware.
03
Pre-Landing
Recover
Arrive sharp — not depleted. Recovery begins before wheels down.
"Designed as a protocol, not a product — repeatable across every flight, every passenger."
Altitude-optimised electrolyte formulation in a 5g sachet — engineered for the specific demands of pressurised cabins.
No new hardware. No operational disruption. Integrates into existing cabin service workflows from day one.
B2B supply to airlines for crew wellbeing programmes, with passenger access via onboard or pre-flight offering.
Not a beverage. A repeatable system — protocol-driven, measurable, deployable at scale.

Why now?
Post-pandemic aviation wellness
Sleep kits, menus, cabin design — airlines have invested heavily. Hydration is the last unclaimed position.
First-mover category ownership
No competitor has defined this category. The brand that names the problem owns the solution.
Powder segment acceleration
The fastest-growing electrolyte format. Optimal for airline supply chains — no liquid restrictions.
Crew wellbeing at the top of the agenda
Major carriers are investing in crew health. Stratolyte converts fatigue from an assumption into a manageable variable.
