Long Haul Flights

Travelling, particularly by plane, can be dehydrating and this may increase the risk of developing a thrombosis.

You must wait for 48 hours before and after a long haul flight (i.e. a flight that will last at least 5 hours).

You must wait for 2 weeks prior to travel if you are likely to be exercising in conditions where the amount of oxygen available is low (e.g. at high altitude).
