10 Ways Porn Damages your Brain

I just finished the message I will bring to our church in two weeks entitled, How Porn Changes your Brain (for the worse). It’s part of a larger series on sex. With my prior interest in the brain and my recent research on the brain and porn, I’m amazed at how deadly porn can be not only to marriages and our walk with Christ, but to the brain. Consider what science is now telling us. 

Until recently the research on how porn impacts the body and brain have been correlative. That is, from a scientific perspective, studies did not show that porn use directly caused these problems (although common sense told us otherwise). The correlative evidence, however, is quite damning in itself. The problem has been that researchers have had trouble finding college students (the most often chosen group for guinea pigs in research) who have not used porn. And, even if they did, it’s questionable the ethics of introducing someone to porn.

Dementia Disease

However, new research is now showing clear causal relationships of porn use to damage to the brain. In fact, the variable (use or non-use of porn) is now becoming more available as a large number (over 75,000) of former porn addicts have formed an on-line community called NoFab. Through surveys, they are posting how their lives have changed for the better after getting off porn. Also, a recent German study has shown a clear causal connection between even moderate porn use and damage to the brain.

Here is what research now indicates that porn does to our brains and bodies.

  1. It becomes addictive. Overstimulation of the brain system that releases the pleasure neurotransmitter dopamine (which internet porn spurs in massive amounts) results in the buildup of the molecular switch protein called deltaFosB, an ingredient common in most addictions.
  2. It impairs memory and concentration.
  3. It numbs you to other pleasures of life and real sex in marriage (called desensitization). You develop a tolerance and need for greater and greater stimulation because real sex has become dull.
  4. Sensitization. Because your reward system has been hammered, you have an amped up attraction to porn that can tempt you to view it through even simple cues like seeing your computer monitor. Your brain goes into autopilot and your reward circuit says, “Do it now!”
  5. It diminishes impulse control and willpower. The fight between clear thinking and temptation is heightened and you have less willpower to say, “No!”
  6. It increases sensitivity to stress. Even minor stresses can lead to cravings and relapse because they activate powerful sensitized pathways.
  7. It literally shrinks your brain. Studies actually show that even moderate amounts of porn can shrink grey matter in areas associated with cognitive function related to our ability to focus. Porn users report pervasive brain fog.
  8. It causes depression and low energy because it interferes with normal dopamine production and signaling.
  9. You become more susceptible to risky behavior. Since porn addicts need a bigger and bigger hit they gravitate to more degrading kinds of porn and risky behavior to get that hit with diminished fears of experiencing negative consequences (i.e., getting caught).
  10. Erectile dysfunction. Porn users become less sensitive to real sex with their spouses and need more and more stimulation to get aroused. Ex-porn addicts report that porn created significant sexual problems, specifically ED. 

That’s the bad news.

The good news, however, is that because the brain is plastic, porn users can break free from porn and change their brains back to a healthy view of sex and sexuality. With Christ’s power, men (and women) can find freedom from the devastating effects of porn.

In my Tuesday post I recommended a great site that offers help. Here’s the link again. If you struggle with porn, please check out that web site.

12 Things that Tempt Men to Peruse Porn

Last week I began a five-week series on sex and sexuality called, The Bare Facts on Sex: God’s Best for Me. You can view archived videos of the messages at our church’s website here. This week I’m completing my message on What Porn Does to your Brain that I will teach in two weeks. I will also post a blog this Thursday on that same subject. You can sign up for my weekly blogs here. As I’ve researched the issues caused by porn, I am shocked not just at its moral consequences, but at its social costs, damage to marriages, and what it does to our brains. In my research I learned that these 12 personal issues may increase the temptation to watch porn. 

These issues may tempt you to view porn (adapted from Wired for Intimacy: How pornography hijacks the male brain by William Struthers, Kindle E-book loc. 575):

  1. The allure of the forbidden: curiosity about a woman’s naked body.
  2. Fantasy: dissatisfaction with the current world and a desire to participate in another.
  3. The pleasure of surrender: giving in to sexual release through images on a screen.
  4. Desire to see women in ecstasy.
  5. The female body becoming an altar at which a man worships.
  6. Controlling personality: a desire to manipulate the environment to gain a sense of security.
  7. Unhealthy introversion: a loner type who isolates himself from social interaction with others.
  8. High anxiety: easily stressed from family, work, or expectations others place on him.
  9. Narcissism: a need to be admired by others around him; needs lots of admiration. See my blog on the narcissistic leader here.
  10. Low self-esteem: sense of inadequacy around other men or women; needs lots of affirmation.
  11. Depression.
  12. Distractability: difficulty keeping focused or controlling impulses; constantly wanting to move to something more interesting.

If some of these issues are often true of you, find a wise accountability partner to help you conquer porn and/or avoid its lure. If you do have a problem with it, you can’t solve it by going solo. I also recommend this excellent site for further help.

As Christians, we must remember this promise for God’s Word.

By his divine power, God has given us everything we need for living a godly life. We have received all of this by coming to know him, the one who called us to himself by means of his marvelous glory and excellence. (2 Pet 1.3, NLT)

The Worrying and Fearful Leader

Worry and anxiety can stifle the effectiveness of the best leader. In my life when anxiety gets the best of me, my leadership always suffers. So, what goes on in the mind of a leader when he or she worries and what can we do about it? Consider these suggestions.

anxiety brain

When we feel anxious, a process in our brain starts because God created our brains to help us survive. When we feel threatened and anxious from a roar we hear outside our tent while camping or from a roar from a nasty email, it initiates a flight-fight response in our bodies.

One significant component of our flight-fight brain structure is called the amygdala, two almond shaped clusters of brain cells (neurons) that activate when we sense real or perceived threat. 2/3’s of the cells in the amygdala are wired to look for the negative. That’s why it’s so easy to get anxious, worried, or fearful. The amygdala is always looking for a problem.  

 Unfortunately, it’s not good at distinguishing between a valid and real threat.

Worry and fear show up in our bodies in several ways:

  • Our heart rate and breathing increases.
  • Our pupils dilate.
  • Saliva production slows (that’s behind dry mouth when we feel anxious or fearful before we speak).
  • Our muscles can tighten (many of us carry our tension in our shoulder muscles and neck).
  • We can feel goosebumps (think of how you feel when you hear the ‘bump’ in the night).
  • We get that ‘anxious’ feeling (norepinephrine, also known as adrenalin, is released in our bloodstream as a hormone and into our nervous system as a neurotransmitter).
  • Memory, decision making, motivation, and attention get diminished (our fear center hogs our limited mental resources).

So what can we do to minimize the effects of anxiety and fear upon leadership.

  1. Awareness: If we constantly live with low level anxiety, our fight-flight centers are more sensitive so it takes less to push us into serious worry, anxiety, and fear. The term, metacognition, means to be aware of awareness or aware of what you are thinking about. Instead of mindlessly rushing through life, often stop during the day to ask yourself these questions to become more aware of your inner world and the chatter in your mind (metacognition).
    • What am I thinking about right now?
    • What are my feelings right now?
    • Are these thoughts and feelings based upon reality?
  2. Labeling: We’ve often been told that to make painful emotions go away, ignore or suppress them. Actually, studies show that doing so does the opposite. Ignoring or stuffing them actually makes them stronger. Instead, take the power out of your painful emotions by recognizing them and naming them. Scientists have discovered that when we label them (i.e., I am feeling anxious), we actually calm our fight-flight centers.
  3. Distancing: Another very helpful way to calm anxiety and fear is to take the proverbial ‘fly on the wall’ perspective as an observer. When you experience these emotions, imagine stepping back as a third person observer and observing yourself and the situation at a distance. Distancing has proved to be one of the most effective ways to calm our fight-flight centers.

I love how Martin Laird, a college professor and writer, uses the metaphor of a mountain’s response to weather to picture how we should respond to unpleasant emotions. He bases his thoughts on Psalms 125.1. Those who trust in the LORD are like Mount Zion, which cannot be shaken but endures forever.

Mt Zion symbolizes God’s power, blessing, and protection. So, when we trust in the Lord and redirect our thinking and our attention, we are like a mountain and how it responds to weather.

A mountain has weather around it all the time. The mountain does not become the weather. It simple observes it. In Christ we are like that mountain with all kinds of external and internal weather around us. Now we may prefer certain kinds of weather, but we are not the weather.

Your anxious thoughts and emotions are not you.

They are simply the weather.

The marvelous world of thoughts, sensation, emotions, and inspiration, the spectacular world of creation around us, are all patterns of stunning weather on the holy mountain of God. But we are not the weather. We are the mountain. Weather is happening—delightful sunshine, dull sky, or destructive storm—this is undeniable. But if we think we are the weather happening on Mount Zion (and most of us do precisely this with our attention riveted to the video [of our internal world, my addition]), then the fundamental truth of our union with God remains obscured … When the mind is brought to stillness (what Paul calls thinking on these things) we see that we are the mountain and not the changing patterns of weather appearing on the mountain. [Laird, Martin (2006-06-07). Into the Silent Land: A Guide to the Christian Practice of Contemplation (Kindle Locations 287-293). Oxford University Press. Kindle Edition]

So, paying attention to our thoughts and emotions is essential for good leadership. If we don’t pay attention to our inner world, we become captive to it and blinded to its potential negative effects upon our souls and upon our leadership.

How Often should Preachers Practice their Sermon?

I’ve served in ministry over 30 years and I’ve preached a lot of sermons. Some have been good and some, well, not so good. Three factors have made the biggest positive difference for me: preparing my heart before the Lord, scheduling adequate study time to avoid feeling rushed, and practicing preaching my sermon. In this blog I suggest a few benefits from practice and describe my practice/preparation process.

gray word on red wall

As a framework, a few insights about me.

  • I’m not an A++ communicator. I’d say I’m a solid B+. God has gifted me with a good mind and relatively good speaking abilities, but I don’t command a multi-thousand person church audience. I’ll speak to several hundred people on an average Sunday.
  • I don’t have a photographic memory that allows me to memorize my sermons.
  • I don’t have unlimited energy, need 8 hours of sleep at night, and go into a semi-comotose mode at about 8:30 each night. So, I can’t pick up extra study hours at night. If study gets done, it must happen during daylight hours.
  • I study slow. I can’t quickly craft a message. Even after three decades of doing it, I still need 15 hours or so to create a message, excluding practice time.

Even with my limitations, I’ve discovered that practicing my sermon yields several benefits.

  1. Familiarity: When I practice, I become more familiar with the homiletic part (how will I say it), a different kind of familiarity than hermeneutic familiarity (what the Bible says).
  2. Improvement: When I practice my message, I notice how I can say things differently which improves what I eventually do say.
  3. Shortening: Practice often helps me realize that I can remove some parts of my sermon without affecting the message I want to convey. I almost always shorten my sermon as I practice it.
  4. Confidence: The more familiar I become with my sermon, the less I have to think about what “comes next” when I preach which increases my confidence during delivery.
  5. Memory: Although I don’t memorize my messages (I work from a complete manuscript), the more I practice, the more it imbeds into my subconscious which frees me to connect better with the congregation through eye contact and body language when I deliver it.
  6. Timing: I usually try to use humor in each message. Professional comedians practice a lot to improve timing in their humor. When I practice, it helps me improve my timing.

Here’s my routine.

  • I complete my study and write my manuscript at least two weeks ahead of time.
  • On the Thursday prior to the Sunday when I will deliver it, I review it again, tweak it, and highlight key phrases (all in Microsoft Word).
    • I save it as a PDF to my iPad app Notability, one of the best PDF markup apps available. I preach from an iPad mini, instead of paper notes. You can read about my experience with an iPad here.
    • I go to an upstairs closet in the church and preach it out loud once.
  • On Friday, I slowly and silently review it, further tweaking it directly on Notability.
  • On Saturday, I preach in out loud in my bedroom closet (second practice).
  • On Sunday morning, I practice it out loud one more time in my closet (third practice).

So, I practice it out loud three times and silently tweak it twice.

I’ve found that this pattern allows me to best prepare, without overdoing the practice.

What is your prep routine?

9 Ways to Boost Brain Power

God gave each of us a two-pound dynamo called the human brain. It’s truly the most amazing physical object in the universe. Yet, many people (and leaders) don’t take care of their brains and later in life they pay the price. However, we can keep boost our brain power and keep our brains healthy and humming along with 9 simple choices.


First, some sobering facts about the brain.

  1. Our brain’s overall volume decrease 5% per decade after the age of 40.
  2. Dendrites at the end of our brain cells (think of the roots of a tree) begin to decline starting in our twenties. The more ‘bushy’ our dendrites, the better and more efficient our brain processes information.
  3. Gray matter (brain cells called neurons) also begin to decline starting in our mid-20’s.
  4. The insulation (called myelin) that wraps around the tail of a neuron (called an axon) thins as we age. The thicker the myelin the faster the electrical impulses travel along the axon. And, faster is better.
  5. The receptors for the neurotransmitter chemical called dopamine decreases. This chemical plays a major role in attention, learning, and reward.

These brain changes lead to memory loss, decreased attention, slowed mental processing, and lessens our ability to learn. However, even with these sobering facts, we can reduce the rate of cognitive decline and keep our brains healthy by applying these 9 choices

9 Ways to Boost Brain Power

  1. Get moving.
    • Exercise is one of the best things you can do for your brain. When we exercise, a chemical called BDNF (brain derived neurotrophic factor) is released and it keeps our neurons healthy. Some call it the brain’s Miracle Grow.
  2. Use it our lose it.
    • Think of your brain as a muscle. The more you exercise it, the stronger it becomes. The more we use our brain, the more we create something called cognitive reserve, the brain’s savings account. As we age, the more cognitive reserve we have developed, the more capacity the brain has to reallocate functions to other regions of the brain from regions that may not be working as well.
  3. Make lots of friends. 
    • Staying connected to others in community helps keep your brain fresh.
  4. Volunteer/serve others.
    • People who volunteer have a much less chance of developing Alzheimer’s disease and have less stress. Prolonged stress on the body can actually shrink our brain, especially in our memory center.
  5. Keep you devotional life strong.
    • At the end of our chromosomes lie tiny end caps called telemeres, much like the plastic sleeves at the end of our shoe laces. Scientists have discovered a positive correlation to the length of these end caps and longevity. In studies of those who regularly mediate, their chromosomes consistenly have longer telemeres. So, a daily quiet time may help you live longer.
  6. Don’t veg in front of the TV.
    • In some sobering new research, scientists have discovered that watching too much TV can alter the brain structure of children in areas related to verbal intelligence. So, monitor the amount of TV you watch.
  7. Eat your spinach.
    • A healthy diet is crucial for brain health. Foods such as dark leafy veggies, blueberries, green tea, and those rich in omega-3 fatty acids (the brain’s building blocks) bodes well for a healthy brain. Some supplements such MCT oil, vitamins E and B, and CoQ10 may also boost brain power.
  8. Learn something new.
    • The brain loves novelty. When we learn something new (learn a new skill or develop a new hobby), we actually encourage growth of new brain cells.
  9. Get adequate sleep.
    • When we sleep the brain is quite active. It consolidates what we learned that day into long-term memory and helps grow new neurons in our memory center (the hippocampus). Sleep also clears out a deposit called beta amyloid that accumulates in Alzheimer’s disease.

Take care of your brain and it will serve you well. Since the brain is part of the body, we should heed the words of the Apostle Paul.

1Cor. 6.19 Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own;  20 you were bought at a price. Therefore honor God with your body. (NIV)
