Farmers like to wrap towels around their necks when farming, which can avoid using neck muscles when working with their heads down and help prevent their shoulders from becoming stiff. Tie a towel around your neck and tie a knot. When you bow your head, the place where you tie the towel can support your chin and bear the weight of your head. The principle is similar to the cervical spine fixator you used when your neck was injured.

If you are overworked and the amount of exercise exceeds the load that the arm muscles can bear, lactic acid in the arm muscles will accumulate and cause soreness. Patients need to brake, rest, stop working or exercise.

Extended data:

Long-term physical exercise can lead to physical fatigue. The qi and blood of the human body are easily overdrawn, overtired and eliminated. This disease is a systemic disease, such as lumbar muscle strain, femoral head necrosis, arthritis, scapulohumeral periarthritis and so on.

People who exercise for a long time are usually stronger. This is because in the process of exercise, some parts of tissues and organs move, so they are more developed. Heart activity will also increase. The premise is that physical strength is not brain power. However, due to the limitation of work characteristics and production methods, the body can only exercise one or several muscle groups, and it is easy to feel tired. If we can't properly combine physical activity with rest regulation, some diseases will occur.
