can't stay healthy...

[Ducttape Dan]

i must be missing something, i do all the uploads like clinics in every city, but overall health stays very poor, can't grow citizens ... do i miss something ?

You may have built too many cities, or you have conquered cities (which gives a lot of unhealth for a while). Hover your mouse over the health symbol, and you'll get a breakdown of the factors that contribute to your health.

It's not unusual to have negative health during the mid-game. It can be prevented, but usually it's still more efficient to expand and just bear the negative health until you have the production base, buildings, or virtues, to fix it.

Perhaps, focus on some early techs that give buildings for health. Also, the Biowell is a life saver in a pinch.

This is not Civ 5, look at the penalties you get for negative health and you should quite easily come to the conclusion that you don't have to stay healthy all the time. In fact, going into negative health is THE way to go if you want to play efficiently. If anything, try to stay above -20 health (because of the science and culture-penalties), that's easy if you build all the health buildings early enough (rule of thumb is to get them after trade depots, production and food buildings), picking health policies and (if you want to get back into positive health instead of just staying above -20) adding biowells.

health is irrelevant and city growth is next to meaningless. Focus on science and energy, then buy all the health buildings you want once you are rolling if it actually matters to you. Personally, I find health to be a so far down my list of prioritys that by the time I get around to adressing it, I'm already just playing out the string until I win.

Remember that you can't produce more health in a city than that city's population.

More precisely, health from buildings and terrain can't, but health from policies related to cities (1 health per city from Prosperity, 1 health per 6 citizens in a city in Knowledge, 0.2 health per building from Magnasanti) is unaffected by how much city health there is.
Anyway, when it comes to dealing with health, until you have a good number of cities it's pretty much pointless to even bother with it. The penalties are very small until you have a lot of cities and population for those penalties to affect, at which point you're either much more capable of dealing with health (mostly from Eudaimonia or Magnasanti) or you've basically already won anyway.

Rushing through the prosperity virtue branch is great for health. Not only is there the flat +7 health one, but there is one that grants +1 health per improved basic resource (so if you control a lot of territory and therefore resources, you will get heaps of health this way). Also there is one that decreases "unhealth" which will usually boost your health by +5 or so depending on the situation.

[gimmethegepgun]

Except other than the free colonist, health is pretty much all Prosperity actually has, and again, focusing on health is a waste of time.

[Ryika]

Prosperity is fine. Not quite as strong as Industry, but it's certainly not as useless as people make it out to be. Its strength comes from the fact that you can go for 7-8 cities and still almost completely ignore biowells.

[gimmethegepgun]

Or you could get 7-8 cities, ignore biowells, AND have Industry, instead of wasting your virtues on Prosperity.

And do what? General consensus is that the fastest victories are done by not ignoring health anymore since the patch.

[highfivingbears]

Try not building factories(or refineries,whatever they're called). I noticed that it had a -2 health decrease

Three words: genetics tech branch. Soon you can produce gene smelters, gene gardens, the Promethean, biowells, souped-up clinics, etc. etc. etc. I build solar collectors, generators, field reactors, thorium reactors, etc. And then I have all the neccessary energy to instabuy most of the health buildings in each new city.
