Why people drink orange juice after blood donation?

It is actually common to be offered a small snack and a drink, such as apple juice or water, immediately after a blood donation, instead of orange juice specifically. The drink provided is typically something light and simple that's meant to help restore lost fluids.

As part of the standard procedure after giving blood, individuals are encouraged to rest for a few minutes and hydrate before leaving the donation site. This prevents potential side effects that might arise from the temporary drop in blood volume during the donation process.
