No, but when you define it that way it's hard to have a discussion about "health". Generally if people aren't dying or aren't living in pain it's unclear what's a good measure or if it can be considered indicative of physical "health".
It's also pretty rare that something would cause great suffering without reducing life expectancy.
There's absolutely a ton of evidence showing improvement to some markers. But similarly you could "improve" them with many drugs and people would naturally be skeptical on whether there's a real improvement to health without trying to treat some specific condition. And you'd usually defer to life expectancy to make the determination.
