Icy water is a shock, and it makes blood vessels constrict. So you're actually get less blood through your AVAs, not more.

冰水冲击力太大了，它会使血管收缩。实际上，身体流通吻合血管的血不是增加了，而是减少了。

You focus it on a very small area, and you can eliminate vascular malformations called arteriovenous malformations, tumors.

你可以将其聚焦在一个非常小的区域，并可以消除称为畸形的血管异常和肿瘤。

Heller says that's smart. The water is cool but not freezing, and you're getting it onto the AVAs in your palms and your face.

海勒说这很聪明。水很凉，但不冰。手掌和脸上的吻合血管(AVAs)处都沾上了水。
