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.
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.
- 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.
- It impairs memory and concentration.
- 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.
- 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!”
- It diminishes impulse control and willpower. The fight between clear thinking and temptation is heightened and you have less willpower to say, “No!”
- It increases sensitivity to stress. Even minor stresses can lead to cravings and relapse because they activate powerful sensitized pathways.
- 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.
- It causes depression and low energy because it interferes with normal dopamine production and signaling.
- 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).
- 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.
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.
- Our brain’s overall volume decrease 5% per decade after the age of 40.
- 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.
- Gray matter (brain cells called neurons) also begin to decline starting in our mid-20′s.
- 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.
- 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
- 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.
- 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.
- Make lots of friends.
- Staying connected to others in community helps keep your brain fresh.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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)

Starting each day well is certainly important. We must prioritize our goals, prepare our soul, and schedule our time wisely. When we discipline ourselves to begin each day with intention and thoughtfulness, we do ourselves and others good. I suggested 7 questions to ask yourself each morning in this post. But what about preparing to end your day? How can we end it well? Consider these 7 questions to ask yourself as you end your work day or before you go to bed.
- Did I treat others with respect, kindness, and God-inspired grace?
- “A new command I give you: Love one another. As I have loved you, so you must love one another. 35 By this all men will know that you are my disciples, if you love one another.” (John 13.34-35, NIV)
- Did I rush through the day, or take time to be truly present with others and with God?
- “Be still, and know that I am God….” (Ps 96.10, NIV)
- Did I treat myself well, respecting my limits and my margins?
- As Dr. Richard Swenson penned in his book Margin, “Margin is the space between our load and our limits and is related to our reserves and resilience.”
- Did I honor God with my time, the responsibilities He entrusted to me, and my competencies?
- Whatever you do, work at it with all your heart, as working for the Lord, not for men…. (Col 3.23, NIV)
- Have I told my kids who live at home or my spouse, “I love you,” at least once today?
- The LORD appeared to us in the past, saying: “I have loved you with an everlasting love…. (Jer 31.3, NIV)
- Have I thanked God for at least one blessing He has given me today?
- Be joyful always; 17 pray continually; 18 give thanks in all circumstances, for this is God’s will for you in Christ Jesus. (1 Ths 5.16-18, NIV)
- If you were to add a seventh question, what would it be?
Ending your day well might be the key to beginning the next day well.
What was your seventh question?
I live in Canada and we celebrated Thanksgiving in October while the U.S. celebrates Thanksgiving in November. Although a few other countries celebrate similar holidays, Canada and the U.S. make a big deal of it. Many people in both countries approach Thanksgiving with a desire to be more grateful, at least on those holidays. It’s great that we highlight gratefulness through a holiday, but did you know that gratitude is actually good for your brain and your body? Consider what science has discovered about this amazing brain fertilizer.
- Can give you more energy. In one research study participants kept a daily journal listing what they were grateful for. Another group recorded what annoyed them. Those who kept a ‘gratefulness’ journal had more energy and enthusiasm and were happier than the other group (Emmons & McCullough, 2003).
- Can help you become more other-centered. In a study by the same researchers, participants also daily journaled what they were grateful for. In addition to similar results to the above cited study, they discovered an interesting side effect. Those in the ‘grateful’ group reported that they were more inclined to help others with a personal problem. They became what is called more “pro-social” (Emmons, 2006).
- Can help you sleep better. Our brains and bodies need adequate sleep. When we don’t get enough sleep, our brains can’t consolidate our experiences from the day into our long term memory. So, without refreshing sleep, our memory and cognitive function suffers. A Chinese study discovered that not only did gratitude improve sleep, but decreased depression and indirectly lowered anxiety (Korb, 2012). So, start and end your day with a grateful heart for more rejuvenating sleep.
- Can make you physically feel better. When we are grateful, we activate brain regions associated with the feel good transmitter, dopamine. Gratefulness also increases the mood neurotransmitter serotonin and the trust hormone, oxytocin. When dopamine is released, it evokes a “do that again” response. So, a grateful heart can feed on itself and help us want to repeat it. Its called the ‘virtuous cycle.’ We simply have to start the process by choosing to be grateful.
- Can help you become less materialistic. Several studies have shown that people with higher levels of gratitude are more likely to have lower than average traits of materialism (McCullough, 2002).This finding reminds of Jesus’ words, In everything I did, I showed you that by this kind of hard work we must help the weak, remembering the words the Lord Jesus himself said: ‘It is more blessed to give than to receive.’” (Acts 20.35)
- Can help combat negativity and the negative emotions that follow. Because our brain has five times more negative circuits than positive ones, we naturally tend to focus on the negative. It’s called the brain’s ‘negativity bias.’ When we are grateful it forces our brain to think about the positive. The Apostle Paul understood this when he wrote Phil. 4.8. Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable — if anything is excellent or praiseworthy — think about such things.
Not only does science speak to gratefulness, it also fills the pages of Scripture.
- 1Th. 5.16 Be joyful always; 17 pray continually; 18 give thanks in all circumstances, for this is God’s will for you in Christ Jesus.
- Psa. 100.3 Know that the LORD is God. It is he who made us, and we are his; we are his people, the sheep of his pasture. 4 Enter his gates with thanksgiving and his courts with praise; give thanks to him and praise his name.
- Col. 3.16 Let the word of Christ dwell in you richly as you teach and admonish one another with all wisdom, and as you sing psalms, hymns and spiritual songs with gratitude in your hearts to God

An old saying about gratitude goes like this.
If you’ve forgotten the language of gratitude, you’ll never be on speaking terms with happiness.
Don’t forget the language of gratitude today!

Mornings are the most crucial part of our day. And how we begin them sets the tone for the rest of the day. Insightful leaders understand this truth and mentally prepare themselves when they get up. Drew Canole, founder of fitlife.tv says, “How you start your day is how you start your life.”
Consider asking yourself these 7 questions within the first 10 minutes of your morning.
- If I could only get one thing done today, what would it be?
- Have I set aside quiet time with God to pray, reflect, and read His Word?
- Is there any unconfessed sin in my life that I should confess?
- Are there any relational issues with others that need rectifying?
- Am I eating a healthy breakfast with plenty of protein and healthy carbs?
- Am I focusing on the positive, good things in life and ministry or do my thoughts immediately turn negative?
- Do I have a consistent routine like getting up at the same time, eating at the same time, taking a shower at the same time, etc. or is each morning dramatically different?
What we do first thing in the morning will dramatically affect the rest of your day. The Psalmist offers great advice with these words.
Let the morning bring me word of your unfailing love, for I have put my trust in you. Show me the way I should go, for to you I lift up my soul. (Ps 143.8, NIV)
How do you prepare for your morning?
