Stretching increases blood flow in the muscles which leads to better oxygen transport. You will feel more awake and fresher in the body and mind. Your body gets a boost of energy that affects your thinking too, so you might feel more creative after stretching.
Furthermore, stress can be relieved since endorphins are released during stretching, which can lead to a sense of tranquility and slight euphoria. When you stretch regularly, you improve your flexibility and range of motion. All muscles are lengthened and relaxed so that your overall posture improves. This reduces the risk of injury or development of muscular pain, such as repetitive strain injury (RSI), a widespread malady of the lower arm, hand, and wrist among pipette users.
So stretching the muscles needed for pipetting is essential when pipetting for long hours. Stretching the arm, wrist, shoulders, lower back, and neck is most important to maintaining flexibility in these areas. Repeated stretching will ensure long muscles and reduce tense, stiff, or hardened muscles after a working day.
