Check out what your latte might be doing to the different parts of your body:

Coffee can make you start to feel more alert and able to concentrate. You may be able to think more clearly. Your pupils may dilate a little. Your vision might even sharpen.

Caffeine in coffee helps your lungs to open up, making it easier to breathe.

Caffeine causes your stomach to produce more acid. This aids digestion, but if you drink coffee on an empty stomach, the increased acid may irritate your stomach lining and cause pain.

Heart and circulatory system
Your blood pressure rises a bit shortly after you drink a cup of coffee. This makes your heart rate slow down, but if you keep drinking your heart rate may increase.

Moderate coffee drinking has been associated with lower rates of cardiovascular diseases.

A small study concluded that increased caffeine levels in the blood seems to have an effect of reducing the risk of Alzheimer's disease.
