This question worries a person who is going to the dacha and back to ride a bike. There he, of course, will take a steam bath, but will his knees be damaged on the way back? Because the joint fluid thickens.
Why should it thicken? Like in a fairy tale about a fox, which has eaten honey on its stomach? Not. The water will not evaporate from the joint.
In fact, joint fluid is a non-Newtonian fluid. That is, its viscosity is very difficult to change depending on various factors. Well, from an increase in body temperature, the viscosity of the joint fluid decreases. That is, it will lubricate better.
If the joint fluid was too thick, the joint would become stiff. Such a joint is more easily injured. A sore, inflamed or festering joint is not bent well just because of the thick fluid.
It is not in vain that athletes do a warm-up before training. Warm-up is also called warm-up. Joints, ligaments and muscles are literally heated there to increase their elasticity and mobility.
That's about the same story with the bathhouse. Heating produces a kind of warm-up.
The only problem is that the bath itself accelerates the heart like physical activity and also provokes dehydration. This can get pretty bad.
But if you do not evaporate too much, wait 15 minutes after the bath and prevent dehydration, then you can then ride a bike. Have you tried it?
