Disease description:

After waking up, my whole body feels sore and weak. What could be the reason? I didn't engage in any intense physical activity yesterday, yet upon waking, I feel inexplicably fatigued. I'd like to consult a doctor—what causes全身 soreness and weakness upon waking in the morning?

After waking up in the morning, bodily aches and weakness may be caused by several factors: 1) recent excessive fatigue or over-exercising, leading to muscle strain throughout the body, manifesting as generalized soreness and weakness; 2) going to bed too late and insufficient sleep at night, which may prevent normal physical recovery, resulting in body aches and weakness upon waking the next morning.
