Your "meta analysis" which:
- only goes to show correlation and doesn't even purport to say anything about causation
- openly admits they did not directly compare men and women
- does not say anything about assigned gender at birth being a factor, merely reported gender
Also says literally word for word what I just said about heat stress and middle age. You linked a study reinforcing my reply to you.
There is nothing wrong with going into the heat often, and in a safe way. Some people have different maximums than others. This is too be expected in literally anything a human can do.
You can stay inside if you want. It's just weird to pretend that you can't "because of science", and I'm not going to help you with this justification by pretending it is valid.
