Because stretching opens up the circulation system of your body, encouraging blood flow. It also activates the muscles involved in the stretch, the tendons and the skeletal system. A morning stretch is like any other exercise done anytime during the day.
Enjoy it!

When we are sleeping, our body is sprawled in some sort of position. Let's say that one of my arms is curled up under my pillow. Regardless of the orientation
of my arm, for it to have moved into that position required muscles cooperating in pairs --- so for my arm, my bicep is contracted while my tricep is relaxed. Sure, I may be "relaxed" because I am asleep, and I may not consciously be holding my arm in that position, but the muscle fibers in the bicep are shortened and contracted (remember, this is an all or
nothing phenomenon at the molecular level). After awakening, stretching feels good because you are basically relieving those agonist/antagonist muscle pairs of their duties. Straightening out my arm will cause my tricep to flex, taking up the job of contracting, while my bicep gets to relax. Many benefits come from stretching the muscles, the most immediate being the relaxation of muscles that have been constricted. The movement of muscles (and limbs in general) promotes blood flow and aids in circulation (as you theorized correctly), including the removal of waste products that may have accumulated in the muscles (such as lactic acid). Stretching increases tissue temperature, and also stimulates the synovial
fluid in the joints, keeping them well oiled.
Stretch five minutes per hour.

When you sleep, your body is in a relaxed state and your muscles are generaly not in use. Stretching in the a.m. helps increase your blood circulation and boosts the blood/oxygene levels in them.
This is the main reason why you should stretch properly before physical exersize.

As you stretch your muscles, they release endorphens into your bloodstream. These endorphens, which are a naturally produced sedative, will make you feel relaxed. These endorphens are also a factor in falling asleep.
