Hygiene: You know you've ignored this too long when your sim starts venting
noxious green gas as they run around the house like a superhero in the spring
time. The best way to remedy low hygiene is a good hot shower. Although
taking a bath or a bubble bath raises comfort as well, it's slower than a
shower and usually remedied when you sim sits or sleeps.
The new community showers at dorms are unfortunately, quite sub par, but when
you barely have enough money to pay the bills, you don't really have a
choice. Hygiene should be especially monitored when your sim exercises. For
the most part, Yoga is the only exercise that doesn't melt away at hygiene.
No really horrible effects come from low hygiene except fellow sims are
repelled away and may be difficult to deal with when the number one thing on
their mind is how to get away from the stench.
Energy: Although it has almost no effect on mood, it's going to almost always
be the bar that your eye will be most focused on, because it is also the
motive with the longest recovery time and which a sim's time frame operates
around. Even with the best of beds, Energy takes a few hours to recover
unless you're keen about the idea of pumping your sim full of caffeine.
Sims who run completely out of energy faint, which is never a good thing, so
make sure your sims have enough energy going for them whenever they go to
class or a community lot. If you have a sim with enough aspiration, relying
completely on the Enigmatic Energizer is a very good idea at university,
actually, relying on the Enigmatic Energizer for everyday of their life is an
even better one, but in order to get a sim that well developed already, you
must have already played them quite a bit before they became young adults.
