Now that's an adrenaline rush!

If something is scary or stressful, your hypothalamus sends signals to pituitary and adrenal glands, which let out hormones (a fancy word for messengers) to tell the rest of the body what to do.

Adrenal glands let out a hormone called epinephrin into the blood, which gets your body ready to fight bad guys or high-tail it outa there!

Muscles feel tense & ready to karate chop your enemies!

Lungs breathe fast & shallow to get extra oxygen to your muscles

Digestive & Urinary systems slow down -- your stomach doesn't want to eat, your bladder might have an accident, and your rectum (hope it's empty) contracts!

Salivary Glands make less saliva, leads to dry mouth & you get less chatty

Sweat Glands make your hands sweaty

Pupils get bigger

Liver lets sugar into the blood for muscle power

Heartbeat & blood pressure turn up!

Example: "Acrobatics -- Now that's an adrenalin rush!"

lungs2How clean is the air you breathe? If you live in a city, I'm sure you notice the difference as soon as you venture into the suburbs; air becomes easier to breathe and might even have a sweet scent! The American Lung Association's list of U.S. cities with the cleanest air made me realize I don't recognize most of these cities. Does fewer humans mean less pollution? Today Canada celebrates Clean Air Day, but you can join in no matter where you live. How can you (or do you) support cleaner air where you live? Some ideas are to bike more, carpool to work, or live closer to work. While we're on the topic of breathing, what's with this Asthmatic Playpen?! I'm not a child, but I want to sit in there.
