Remedy for swelling/water retention long haul flight

[Hellsbellsy]

Does anyone have any successful remedies to prevent severe leg/face swelling and generally everywhere after a long haul flight?
last time I flew I had severe swelling for most of my trip. Obviously I know to drink lots of water etc, but wondering if people have had success with things like electrolytes etc

I’m wondering about Davina Taylor’s electrotides?

Flight socks- make sure you’ve measured your calf’s to get the right size. No alcohol. Get up and walk around as much as possible. Stretch if you can - I’ll do 10 squats every time I go to the loo. Electrolytes will help with staying hydrated as well.

If it’s severe I’d go and see you doctor for advice as well.

Ok thanks, I’ll get some proper flight socks
