1. Hand fatigue: When writing with a brush for a long time, hand muscles will contract and relax continuously, which will easily lead to hand fatigue and soreness.
2. Muscle problems: Frequent use of hand muscles may lead to muscle fatigue, stiffness and muscle strain.
3. Joint problems: Often writing with a brush can easily lead to joint problems, such as wrist pain, arthritis and joint toughness.
4. Vision problems: Staring at the paper for a long time may lead to problems such as eye fatigue, dry eyes and decreased vision.
In order to reduce these potential problems, the following measures can be taken:
1. Pay attention to rest: take a proper rest and relax the muscles of your arms and hands at regular intervals.
2. Hand exercise: Do some hand relaxation and exercise, such as rubbing hands and loosening fists. Promote blood circulation and muscle relaxation.
3. Use correct posture and tools: Use correct writing posture to keep hands and wrists in a natural state. Choose the right brush and paper to reduce the excessive burden on your hands.
4. Maintain a good posture and environment: maintain a correct sitting posture, adjust the light and writing height, and reduce the burden on the eyes.
Nevertheless, if you feel the symptoms are serious or persistent, please consult a doctor or related professional in time. Generally speaking, there will be no obvious health problems if you master the writing time and precautions properly and write calligraphy all the year round.
