Jäykistyminen

Jäykistyminen, a Finnish term, translates to "stiffening" or "rigidity" in English. It generally refers to a loss of flexibility or suppleness in a material or a living organism. In a physical context, jäykistyminen can describe the process of a substance becoming harder and less yielding. This can occur due to various factors such as temperature changes, chemical reactions, or the passage of time. For example, certain liquids may solidify and become rigid when cooled, or wood may harden and become less flexible as it dries.

In a biological sense, jäykistyminen can refer to the decreased mobility or increased stiffness experienced by muscles or joints. This is often associated with aging, injury, or certain medical conditions. For instance, a person might experience muscle jäykistyminen after strenuous exercise or due to conditions like arthritis. The sensation is one of reduced range of motion and a feeling of tightness. While sometimes a temporary state, prolonged or severe jäykistyminen can impact an individual's ability to move freely and perform daily activities. The underlying causes are diverse and require appropriate diagnosis and treatment.
