Question: "Suwen·Five Zang-organs Generation Chapter" says: "Eat more spicy food", what phenomenon can it cause?

I) Eating too much spicy food will reduce the elasticity of the tendons, blood cannot be transported to the nails, making the nails brittle and easy to break, and at the same time it will cause the tendons to be not soft, and the nails to dry and appear dull.

Choices:
Consuming large amounts of spicy food may increase heat in the body, which causes the skin to release sweat, leading to excessive dehydration, making the body weak and prone to heatstroke.
Excessive intake of spicy food can accelerate the metabolism, leading to an increased need for water, which may cause dehydration and a reduction in skin elasticity, giving a dry and wrinkled appearance.
Eating large quantities of spicy foods will increase bile secretion, leading to excess fat digestion and thus causing rapid weight loss, followed by malnutrition and frailty.
Excessive consumption of spicy food may weaken the stomach lining, potentially leading to increased acid production and resulting in persistent heartburn or acid reflux, and possibly ulcers.
Eating excessive spicy foods can cause the blood to thicken, reducing its ability to flow smoothly, which may lead to clot formation and potentially dangerous blockages in the arteries.
Consuming excessive spicy food results in the weakening of the bones, which impedes the flow of marrow to the joints, causing joint stiffness and decreased mobility, and also leads to dry, brittle joints.
Excessive eating of spicy foods causes the blood vessels to constrict, leading to poor circulation and resulting in numbness in the extremities, and might also result in tingling sensations.
Consuming considerable spicy food can lead to elevated stomach temperatures, and result in muscle inflammation, causing general body fatigue and malaise.
Eating too much spicy food will reduce the elasticity of the tendons, blood cannot be transported to the nails, making the nails brittle and easy to break, and at the same time it will cause the tendons to be not soft, and the nails to dry and appear dull.
Overindulging in spicy food weakens the cartilage, which prevents lubrication in joints, leading to movement difficulties and causing painful, stiff articulations.
