Intimate Partner Violence.

According to the Centers for Disease Control and Prevention, intimate partner violence includes victimization by current and former spouses or current and former dating partners. Violence can include physical, sexual, emotional, and economic abuse, according to the Department of Justice's Office on Violence Against Women.

Worldwide: Thirty-five percent of women worldwide have experienced either physical and/or sexual intimate partner violence or non-partner sexual violence, according to the United Nations.

According to a Global Study on Homicide, of all women globally who were the victims of homicide in 2012, an estimated half were killed by intimate partners or family members. United States: Each year - Over 12 million women and men are victims of intimate partner violence, according to the National Domestic Violence Hotline. More here.


"Fight Or Flight": The Effects Of Adrenaline on The Human Body And Self-Defense.

An adrenaline rush is one of the body's vital defense mechanisms. A stressful situation will trigger the release of the hormone adrenaline, also known as epinephrine, into the bloodstream.

The production of adrenaline occurs in the adrenal glands, which sit above the kidneys. Adrenaline is responsible for the fight-or-flight reaction to a threat, and it triggers specific processes in the body. For example, it might make the body send extra oxygen to the lungs to aid a person to run away.

As well as allowing a quick escape from danger, adrenaline has other effects on the body. These include:
  • decreasing the body's ability to feel pain
  • increasing strength temporarily
  • sharpening mental focus, which will allow a person to think quickly and form a clear plan to escape a potential threat
However, the release of adrenaline into the body may sometimes occur when there is no real threat. The hormone has the same effect on the body whether or not the danger is present. More here.

When adrenaline courses through your system during a fight, you can be stabbed, shot, or badly mangled and yet persevere, at least until the pain kicks in afterward. Your ability to think rationally is greatly reduced. The good news is that you tend to become stronger and more resilient than usual. The bad news, however, is that you will likely have degraded motor skills, experience tunnel vision, and perhaps even suffer temporary hearing or memory loss.

While precise movements are extraordinarily tough, even imprecise ones like grabbing a wrist or hooking a leg can be problematic even if you are highly trained. If you try to get too fancy, you will hurt your chances for success in a fight. However, gross motor movements, especially those that target vital areas of the adversary's body, can work pretty well.

The more comprehensive and realistic your training is, the better you will perform in actual combat because conditioned responses can help you counteract, or at least work through, the effects of adrenaline.

Conversely, the more stressed you are through exertion, fear, or desperation, the harder it is perform.
