This is often called living an unhealthy lifestyle, or leading an unhealthy lifestyle.

You are living a sedentary life!

Thank you for your responses!
How about "neglect one's health" and "get a run-down"?

[Curious Cat]

"Getting a run-down" is what you end up with living an unhealthy lifestyle and neglecting your health ;)

It can be also said a person enjoys detrimental habits :) I think so...
Also 'health-damaging behaviour(s)' can be used to describe all these.

Hope it helps.

Curious Cat, thank you for your clear explanation and punchy expressions.
Both "health-damaging behavior" and "a person enjoy detrimental habits" sound that the person is completely health-unconscious.
