Studies suggest that any situation in which someone spends hours sitting in one place can increase the risk of a Deep Vein Thrombosis (DVT). But this can happen with any stationary leisure activity – including watching television, listening to music or reading a book.
It is advised that prolonged periods of inactivity should be avoided whether you’re playing a game, reading a book, or taking a flight. Take regular breaks and move around to stimulate blood flow through to the extremities. You should also stop playing should you feel unwell and, if symptoms persist, consult a doctor.
