How much hydration do you lose when flying?

In general, the body will adjust to the new time zone at the rate of one or two time zones per day.

Jet lag is temporary, so the prognosis is excellent and most people will recover within a few days.

What flying does to your body?

Airplane Travel and Blood Oxygen Saturation

Local hypoxia causes vasodilation (decrease in blood pressure) and increased capillary permeability, as well as increased ventilatory effort and heart rate. One study found a passenger had a blood oxygen saturation of 94% at ground level and 85% at altitude.
