You don't have to be a psychologist to notice the effects that high temperatures have on people. Weather can affect our behaviour in many different ways.
Weather and animal behaviour
The behaviour of animals is often closely linked to the approaching weather. It is suggested that bees stay close to their hives when a summer rainstorm is on the way, while birds fly close to the ground, increase their foraging or even gather to roost before the bad weather sets in. During good weather, birds fly higher in the sky, while even spiders are supposed to be more active.
So how does the weather affect our behaviour?
