While we hear accounts of more than 4000 US soldiers killed in the Iraq war to date, the number of returning veterans who suffer from post-traumatic stress disorder (PTSD) numbers in the tens of thousands. A result of the constant conflict, anxiety, and daily threats of death PTSD has been referred to in many ways: Shell shock, combat fatigue, and battle fatigue. Post-Vietnam syndrome is the expression that was used as a result of the Vietnam conflict.

The US National Institutes of Mental Health alert us to the characteristics of PTSD. These include a sustained and disruptive set of feelings that occur after a particularly traumatic event. These unpleasant episodes recur at frequent intervals.

One feature is constant video replays, that is, remembering and replaying the event for months after. This repeated and recurring stress means we have trouble sleeping. Some people have very dramatic and violent nightmares, and most wake feeling that their sleep did not refresh or re-energize them.

It’s interesting how many people still have so many common misconceptions about facial blemishes, and especially about something like acne skin care. Not only do these misconceptions fail to actually treat acne the way it should be treated, they may actually be doing quite a bit of damage to their skin and making it worse.

Fortunately, correct acne skin care isn’t hard to understand. You just need to know the facts about the causes of this condition, and how to treat it.

The cause of acne is pretty much well known by now. Dirt, oil, and other irritants settle in the pores and cause this irritation or eruption that we call a pimple or acne. This dirt can be from everyday pollutants and elements in the air; our skin exists to protect our innards from dirt so that’s why it settles there in the first place.

The prevention of acne therefore becomes extremely important for people working in polluted environments such as industries, thermal power plants, construction sites or people who drive about a lot on polluted city roads.
