Stress

Acute stress is a natural warning signal to the body that helps us respond to short term threats or changes in our environment. It is a key survival mechanism. As a physiological response, it mobilises our energy in anticipation of action, such as flight or fight. It can be broken down into four responses: fright (arousal), flight (avoiding the perceived harm is often the preferred response to fight); fight (facing up to the harm) and freeze (playing dead and hoping the bear/threat moves on). These stages can apply to every day stressors too.

When we are healthy, we have the energy to deal with short term or acute stress, for instance, running to catch a bus. Our heart rate goes up, our blood sugar levels alter, our perspiration increases to help cool the body as we run. These reactions are all triggered by the stress hormones, adrenaline and cortisol. When we are first aroused, say, by seeing our bus before we get to the bus stop, we produce adrenaline and noradrenaline (the American terms are epinephrine and norepinephrine) for a few minutes to help mobilise us to get there in time. When the stress is over (whew! we made it) our body recovers quickly, balance is restored.

Cortisol mobilises energy from reserves stored in the liver and muscles to help us ‘fight’ or ‘flee’. The trouble is it can keep pumping into the system well after the stressor has passed.

Cortisol continues to flood our system if we have many stress triggers in our life. Today the stressors tend to be psychological, worries about social position, family feuds, economic success or loneliness, rather than physical threats such as warring tribesmen or sabre-toothed tigers. Our body responds to the psychological threats in the same way as our ancient ancestors’ bodies did to those physical threats.

As a person become used to/desensitised to certain levels of shocking images on porn sites, they need more arousing, more shocking images to get a high. Anxiety increases sexual arousal which involves a bigger surge of dopamine. High levels of cortisol in the system are a biological marker for not only stress, but also depression.

Chronic Stress

Stress can accumulate below our conscious awareness. Suddenly we can feel overwhelmed by life and feel unable to cope. We have no resilience to conflict or problems. A stressed brain relies on habit. Creative thinking is too hard. Too much stress, for too long, becomes chronic stress. This is when our body is not able to restore itself again as it does with acute stress. It’s what wears us down, compromises our immune system, makes us more vulnerable to accidents and leaves us feeling depressed, anxious and out of control. That is when we are more vulnerable to taking other stimulants, drugs or alcohol, as well as more extreme internet stimulation to make us feel better and avoid the pain.

Chronic use of internet pornography puts a huge stress on the body’s energy reserved and leads to all kinds of physical and mental problems. HPA Axis Dysregulation in Men With Hypersexual Disorder (2015) – A study with 67 male sex addicts and 39 age-matched controls. The Hypothalamus-Pituitary-Adrenal (HPA) axis is the central player in our stress response. Addictions alter the brain’s stress circuits leading to a dysfunctional HPA axis. This study on sex addicts (hypersexuals) found altered stress responses that mirror the findings with substance addictions.

How we manage stress over the years is key to our wellbeing and our relationships. As we’ve seen from the Grant study, addiction, depression and neurosis are the biggest barriers to a healthy, happy relationship.

Stress

Stress shifts the body’s focus of attention and energy supply from the core areas like the brain, digestive system and reproductive organs in order to feed energy to those areas that need energy immediately to get us out of the perceived danger. That is why over time, unless we manage our stress properly, and stress is inevitable, we develop digestive conditions like irritable bowel syndrome, or a poor memory and an inability to concentrate for long. We weaken our immune system, we catch infections more easily and take longer to heal. Stress ages the skin and body.

Under chronic stress, adrenaline creates scars in our blood vessels that can cause a heart attack or stroke, and cortisol damages the cells of the hippocampus, crippling our ability to learn and remember.

Individually, the worst kind of stress is the feeling that we have no control over the problem, that we are helpless.

In short, stress wears us out.
