This might be a stupid question but was wondering as to is it possible to have to 2 game sessions in 1 day.Does this have an effect to the body possibly more prone to injury or other health problems.Please advise.
I think you should consider how long the sessions are, the intensity of the sessions, the marginal gains from each session, and other workouts for badminton that you do for fitness. The duration and intensity of the sessions, along with the other workouts for badminton that you do for fitness should all be considered because you could injure yourself if you don't protect yourself properly. The sessions should be intense enough so you can focus, but you should also consider that you might be able to dedicate this potential game time to training time instead.
Additionally, since you are in Malaysia, dehydration will be something to consider. Make sure enough fluid intake and also stretching routines before and after sessions. Also consider paying attention to diet as you will need more energy and protein.
There is nothing wrong with having 2 sessions in 1 day. I use to do that all the time when I was in China, and even here still train twice a day sometimes. You just need to make sure that you have proper hydration and nutrition since you will be burning a lot of energy. As well to stretch and warm up properly as well as cool down and stretch when finishing as to not be sore. Nothing is worse than training and then having a long break, getting cold muscles and trying to train again. It can be a painful process warming back up. There are also many other things, while it is possible to do 2 hard physical sessions its better to have one that is harder physically while the other is more of a technical/technique practice.
