Put the paragraphs in the right order.

B Even this nervous energy gets the heart pumping faster!
Energy levels are also directly affected by temperature. When people are hot, their blood vessels expand, their faces and chests blush a bright red as a biological cooling mechanism. When people are cold, their blood vessels do just the opposite, constricting to trap heat inside.

A This built-in system keeps

the human body from reaching dangerous levels of extreme temperatures. An inconvenient

side effect of this automatic heating system is that with constricted movement of blood,

circulation slows down considerably.

This is why

it's so important to exercise regularly, to improve circulation and to get oxygen flowing.

C For many years people have understood that sunlight, cloudiness, stormy conditions and falling barometric pressure can affect their health. When the barometric pressure drops, joints and old injuries ache. Knees and lower back areas become stiff and swollen. Lack of sunlight affects the production of serotonin, it influences our moods and sleep patterns.

D The sun is a person's most important source of vitamin D.

Without enough sunlight depression rates are increased, it often happens during the winter months.
On the contrary, people become

calmer in rainy days.

Sleepy cloudy days and

the sound of rain on the rooftop cause relaxation. But storms excite

some people, filling

them with adrenaline while they fill others with fear.
