I think this is making the assumption that temporally elevated HR and BP is bad.

[goodroot]

Right, the rationale for why saunas and heat stress is good for you is specifically because it raises the heart rate.

[retrac]

Hot sauna is often cautioned against for those with existing cardiac or vascular problems, with some reason.

[DANmode]

Exercising or stressing damaged or degenerated tissues = bad

[hbcdbff]

Sauna raises HR without increasing blood pressure though (modulo some possible initial short spike at the beginning), because your blood vessels dilate.

[iwontberude]

Cannabis causes dilation of blood vessels and elevated HR, it’s the same effect. If you take a big dab you can definitely feel your blood pressure drop and muscles relax even though your heart rate has increased.

[kranner]

It's a fair assumption being a known potential cause of death. Of course I'm now assuming death is bad.

[kataklasm]

By that argumentation sport is bad and a potential death risk factor, it also elevates heart rate and blood pressure!

[parineum]

It has substantially more benefit than that risk. Physical exertion also has the added benefit of lowering rest hr and bp.

[johnisgood]

Yeah! I added that as an example and then edited it out.

Your parent's comment makes no sense.

Water can kill you, too! It does not mean that drinking water is bad.

[literalAardvark]

I think you'd be surprised how often doctors still say that

Not to mention art, sex, walking, etc, etc
