What are the symptoms of overwork in humans

Overwork may lead to symptoms such as headaches, muscle aches, lack of concentration, sleep disorders, and weakened immunity. Long term fatigue may lead to health problems such as chronic fatigue syndrome, cardiovascular disease, endocrine disorders, digestive system diseases, psychological disorders, etc.

1. Headache

When there is mental or physical exhaustion, continuous tension and contraction of cerebral blood vessels may cause tension headaches, manifested as dull pain or tightness in the head. Long term excessive eye use can exacerbate muscle fatigue around the eyes, which may be accompanied by dizziness or blurred vision. Working in a hypoxic environment can exacerbate headache symptoms for some individuals.

2. Muscle soreness

Excessive exercise or maintaining a fixed posture can lead to lactate accumulation, causing muscle stiffness and delayed onset soreness. If not relieved in time, it may develop into muscle fiber injury, which is commonly found in the shoulder and neck area of the upper limbs and around the waist, back, and knee joints of the lower limbs. Cold environments can increase the risk of muscle spasms.

3. Lack of concentration

Prolonged excitement in the cerebral cortex can reduce the efficiency of neurotransmitter transmission, leading to delayed response and memory loss. Part of the population may experience an increase in work error rates and a decline in judgment, which may continue to affect cognitive function.

4. Sleep disorders

Excessive excitation of the sympathetic nervous system can lead to difficulty falling asleep or shallow sleep, manifested as frequent awakenings and early awakenings at night. Some individuals may experience disrupted circadian rhythms, with daytime sleepiness but nighttime insomnia, which may lead to long-term anxiety.

5. Decreased immunity

Continuous stress state can inhibit immune cell activity, manifested as recurrent colds or oral ulcers. Slow wound healing and worsening allergic reactions are also common manifestations, and women may experience menstrual cycle abnormalities.

It is recommended to establish a regular sleep schedule and ensure 7 hours of sleep every day, get up and move for 5 minutes every hour of work, and supplement foods containing vitamin B and magnesium elements such as whole grains and dark green vegetables appropriately. If fatigue symptoms persist for more than two weeks, medical attention should be sought to investigate potential diseases such as thyroid dysfunction or anemia, and self medication should be avoided. Tai Chi and Ba Duan Jin, among other soothing exercises, can help improve autonomic nervous system regulation function. Severe insomnia patients should use sedative drugs under the guidance of a doctor.
