The fish themselves though are also highly effective in making people feel calm and relaxed and many studies have demonstrated that watching can help to ease stress. This means that when an employee comes off of the phone to an angry client and is stressed and upset, rather than being too flustered to work, they will likely be calmed by the gentle noise and pleasant lighting and so be able to calmly focus their attentions on their work. This effect can also help to prevent depression and claustrophobia which are two serious problems that many people get in office jobs and could be seen as a kind of office related malaise. This comes about as people come into the same office day after day and feel `cramped` inside their desk space. As such it is important to prevent your staff from feeling oppressed and to make them feel a bit more `outdoors`. Putting plants in the office has been shown as a great way to do this as it makes your staff feel more like they`re outdoors – which is where we are naturally designed to be – and less like they`re coming into the same cubicle day after day.
