After plasma donation, how long must you wait before flying?

Explanation:
After plasma donation, there is a temporary drop in circulating plasma volume. Flying soon after can expose you to reduced venous return and potential dizziness or faintness in the cabin, especially as cabin pressure and humidity affect your body. Waiting 24 hours gives your body time to restore plasma volume toward normal, reducing these risks during flight. Stay well hydrated and avoid strenuous activity during that period. If you feel dizzy, faint, or have bleeding at the donation site, seek medical advice. Shorter than 24 hours doesn’t give enough recovery, and longer than needed isn’t necessary for flight safety.
