Does Recovery Wear Really Recover? Part 5

My father-in-law (95) suffers from frequent nighttime urination.
In order to further verify and evaluate the fact that my husband and I no longer wake up to use the bathroom at night,
"That's it! Let's see what happens if we have Grandpa wear recovery wear."
That is what we decided.
However, the dirt-cheap Workman recovery wear that we wear is sold out everywhere, and there is no prospect of being able to purchase it.

So, I searched around and found this.

This is recovery wear released by Alpen, a brand familiar for sportswear. Even if the manufacturer is different, the functions, mechanisms, and features are the same: special fibers radiate far-infrared rays emitted from the human body, which promotes blood circulation.

The price for the cheapest items is on par with Workman, at 2,999 yen each for a long-sleeved T-shirt and long pants. The winter velour fabric items are 4,999 yen each. Since the 2,999 yen ones were mostly sold out, I bought one set of the velour material and gave it to my father-in-law.
My father-in-law said he wakes up to use the bathroom four times a night. If he can reduce that even once, it would be a huge success. I will keep an eye on things for a while and ask him for his thoughts.
