Consuming green apples and cucumbers is doing very well for your health, but have you thought about how their scent affects your psyche? Surely not! Smelling them can significantly reduce the feeling of claustrophobia.
Studies have shown that smelling green apples and cucumbers can alter the perception of space, making places look bigger than they actually are. So if you are suffering from claustrophobia or if you just do not like the feeling that small, closed places give you, smell a green apple because it will help you a lot.
On the other hand, the scent of barbecue has the opposite effect on your psyche, making the seats / rooms look smaller than they are.
