Ways into Health

(This could be a medical thread, but no it’s only a game )Health, as we all know is the key to everything, much more important than happiness (don’t flame me, there is another article on happiness here).

This article identifies the factors that will lead a population to be healthy, and also notes some of the unhealthiness-causing elements.

As the player selects more difficult levels, cities become quickly unhealthy even with small populations, so having a good knowledge of the health factors will help the player to create and manage a stronger empire.

Here are the health bonus you start with for every difficulty level:

[LIST]
[*]SETTLER ______4
[*]CHIEFTAIN____4
[*]WARLORD_____3
[*]NOBLE________3
[*]PRINCE_______2
[*]MONARCH ____2
[*]EMPEROR_____1
[*]IMMORTAL____1
[*]DEITY________1[/LIST]

Generally speaking, you will try to have more healthiness than unhealthiness. It doesn’t matter where the healthiness and unhealthiness comes from.
As long as you have more healthiness than unhealthiness, you have no :yuck: green faces.
If unhealthiness is higher than healthiness, you’ll have
[unhealthiness – healthiness] food lost every turn.

Note that an unhealthy city can’t have a “we love our leader” day. It’s not game changing but it’s still a loss, and it’s avoidable. So, how do you get the healthiness you need to grow?

In vanilla cIV, there are exactly 8 ways to get more health (and 3 to have unhealthiness).
[LIST]
[*]trait : expansive gives +3 health (+2 only in warlords patched version and BtS)
[*]Fresh water
(a city built next to a river, a lake or an oasis will gain 2 points of health)
[*]Terrain
(each forest in a city’s fat cross gives 0,5 health)
[*]resources (see chapter 1)
(Banana; Clam; Corn; Cow; Crab; Deer; Fish; Pig; Rice; Wheat)
[*]buildings (see chapter 2)
(Aqueduct; Granary*;Grocer*;Harbour*;Hospital; Supermarket*, public transportation in BtS)
[*]civics
(environmentalism : +6 health in all cities)
[*]wonders
(Hanging Gardens : +1 health in all cities)
[*]techs : Genetics gives you +3 health.
I won’t expand a lot on future techs. Every future tech gives you +1 health in every city. But who cares? The game is over at his point![/LIST]* : depends on a resource

where does unhealthiness come from :
population itself = “too crowded” :
1 unhealthiness for each population point (yes the 1st pop thinks it’s already too crowded )
terrain :
Each flood plains account for 0,4 unhealthiness each. With 20 flood plains, that’s 8 unhealthiness.
Each jungle tile accounts for 0,25 unhealthiness.
Fallout accounts for 0,5 unhealthiness each.
buildings :
(Airport; Coal Plant; Dry-dock; Factory; Forge; Laboratory, IronWorks, Industrial park in BtS)
Resources in BtS:
(Oil and coal with factory and/or industrial park)

If I missed some unhealthiness factors, let me know.

Note that there are ways to reduce unhealthiness.
Cutting the jungle reduces terrain unhealthiness.
Building a recycling centre removes building unhealthiness.

There are 14 health resources

For each resource, you need either to
– have it on a tile included in you cultural borders, have the right improvement built and have the tile connected to your cities
– trade for it

[LIST]
[*]Corn : farm improvement, requires agriculture tech
[*]Rice : farm improvement, requires agriculture tech
[*]Wheat : farm improvement, requires agriculture tech
[*]Clam : working boat, requires fishing tech
[*]Crab : working boat, requires fishing tech
[*]Fish : working boat, requires fishing tech
[*]Banana : plantation improvement, requires calendar tech
[*]Cow : pasture improvement, requires animal husbandry
[*]Pig : pasture improvement, requires animal husbandry
[*]Sheep : pasture improvement, requires animal husbandry
[*]Deer : camp tech, requires hunting

[*]Spice : plantation improvement, requires calendar tech
[*]Sugar : plantation improvement, requires calendar tech
[*]Wine : wineyard improvement, requires monarchy tech ,
note that spice, sugar and wine (strangely enough! It should provide unhealthiness IMHO) provide happiness, they only provide health through a grocer[/LIST]

So there is a potential of +11 health, that can be increased to +25 health including building effects, from resources.

From those:
3 (rice, corn, wheat) require Agriculture, and can be doubled with a granary (requires Pottery)
1 (deer) requires Hunting and can be doubled with a supermarket (requires Refrigeration)
3 (clam, crab, fish), require Fishing and can be doubled with a harbour (requires Compass)
3 (cows, pigs, sheep) require Animal Husbandry , +3 more health with supermarket (requires Refrigeration)
3 (banana, sugar, spice) (only 1 giving health directly) require Calendar, + 3 more with grocer (requires Guild)
1 (wine) (not giving health directly) requires Monarchy, +1 health with grocer (requires Guild)

Aqueduct: +2 health, requires mathematics and masonry;
Granary : +1 from corn, wheat, rice, requires pottery;
Grocer : +1 health from bananas, spices, sugar, & wine, requires guilds;
Harbour : +1 health from clams, crabs, & fish, requires compass;
Hospital : +3 health, requires medicine;
Supermarket : +1 health from cows, deer, pigs, & sheep, requires refrigeration

You can have a total of +21 health from buildings, 16 of those being already accounted for in chapter 1: the resources.

And as I mentionned in the first post,
recycling centre removes unhealthiness from other buildings, as forge, drydock and factory. It requires Ecology which is so near to the end of the tech tree you just can’t rely on this too much.
