Arthritis is one of the oldest diseases on earth and is an inflammatory disease of the joints, the cause of which can be various:
- body dysfunction;
- excessive physical activity;
- consequences of trauma.
Joint discomfort in bad weather is connected with fluctuations in atmospheric pressure, which leads to a change in the tone of the blood vessels that supply the joint. This, in turn, can cause changes in the production of synovial fluid in the joint capsule and, therefore, in the pressure there.
When the pressure in the joint capsule changes, the pain receptors are irritated, which is manifested by pain. This sequence of changes is typical for an injured joint, as healthy tissue does not respond to changes in the weather.
When a person is weather-sensitive, his or her body cannot adapt to the changed atmospheric pressure in time. When it is cloudy or raining outside, it means that the atmospheric pressure has decreased; and if the pressure in the joint capsules does not decrease, their internal pressure begins to overstretch the joint walls, which causes painful sensations.
