Why Can’t You Clench Your Fist Right After Waking Up?

The video explores why making a fist is difficult immediately after waking up. It explains that this phenomenon is due to the body's reduced blood flow and electrolyte distribution during sleep. Electrolytes like potassium, calcium, and sodium are crucial for muscle contraction and relaxation. Upon waking, the body gradually resumes normal blood flow, which can delay muscle function.
