The Science Behind Low Mood And Energy
Lewis Howes Podcast with TJ Power | May 8, 2025
In this fast-paced, hyper-connected world, many of us struggle with low energy, mood swings, and an inability to focus. But what’s really causing these issues? According to neuroscientist TJ Power, the answer lies in our modern lifestyle—specifically, our relationship with technology, food, and instant gratification. In this blog post, we’ll dive deep into the science behind these challenges and explore practical tips to help you reclaim your energy, focus, and overall well-being.

The Dopamine Dilemma: Why We’re Addicted to Quick Fixes
Dopamine, often referred to as the “feel-good” neurotransmitter, plays a crucial role in how we experience pleasure and motivation. However, our modern world has hijacked this system, leading to a cycle of highs and crashes that leave us feeling drained and unfocused.
Key Takeaway: Every time you open social media, your brain experiences a rapid spike in dopamine—similar to what a hunter-gatherer would feel after five hours of hunting. But instead of a slow, steady decline, this spike is followed by a quick crash, leaving you feeling low and unmotivated.
This constant cycle of dopamine spikes and crashes is one of the primary reasons we struggle with focus and energy. TJ Power explains that our brains weren’t designed for this level of overstimulation. In the past, dopamine was released in response to meaningful, effortful activities like building a shelter or hunting for food. Today, we get the same dopamine hit in seconds by scrolling through Instagram or watching short videos.
The Impact of Social Media on Mental Health
Social media is one of the biggest culprits when it comes to disrupting our dopamine levels. The constant stream of new content, likes, and notifications creates a hyper-stimulating environment that’s hard to resist.
Key Takeaway: The average person opens their phone 140-170 times a day, with social media apps like Instagram being the primary source of dopamine spikes. This overstimulation leads to a “dopamine crash,” resulting in low mood, lack of energy, and difficulty focusing.
TJ Power suggests that reducing the frequency of social media use can have a profound impact on your mental health. He personally limits his social media usage to three times a day—10 a.m., 3 p.m., and 8 p.m. This simple boundary helps him avoid the constant dopamine spikes and crashes, allowing his brain to reset and regain balance.
The Role of Ultra-Processed Foods and Sugar
While social media is a major factor, it’s not the only one. Our diets also play a significant role in how we feel. Ultra-processed foods and sugar can wreak havoc on our dopamine levels, leading to energy crashes and mood swings.
Key Takeaway: Ultra-processed foods and sugar cause rapid dopamine spikes, similar to social media. Over time, this can lead to a “numbing” effect, where even rewarding experiences like career achievements or meaningful relationships feel less satisfying.
To combat this, TJ Power recommends focusing on whole, unprocessed foods and reducing sugar intake. This helps stabilize your dopamine levels and prevents the constant highs and lows that come with a diet high in processed foods.
ADHD: A Modern Epidemic?
Attention Deficit Hyperactivity Disorder (ADHD) is becoming increasingly common, and TJ Power believes our modern lifestyle is a significant contributor. While some people are genetically predisposed to ADHD, many others develop symptoms as a result of overstimulation from technology, poor diet, and lack of meaningful, effortful activities.
Key Takeaway: People with ADHD often have a lower baseline level of dopamine, which makes them more susceptible to the overstimulation of modern life. However, when they find activities that truly engage them, they can experience hyper-focus and excel in those areas.
TJ Power reframes ADHD as an “attention deficit hyperactivity ability,” emphasizing that individuals with ADHD can thrive when they find activities that align with their interests and passions. For example, someone with ADHD might struggle in a traditional classroom setting but excel in a hands-on, creative environment.
Practical Tips to Reclaim Your Energy and Focus
Now that we’ve explored the root causes of low mood and lack of focus, let’s dive into some practical tips to help you reclaim your energy and improve your mental well-being.
1. Set Boundaries with Social Media
- Limit your social media usage to specific times of the day (e.g., 10 a.m., 3 p.m., and 8 p.m.).
- Use app blockers or grayscale mode to reduce the appeal of your phone.
- Physically separate yourself from your phone during designated “phone-free” times.
2. Prioritize Slow Dopamine Activities
- Engage in activities that require effort and provide long-term rewards, such as exercise, cooking, or learning a new skill.
- Avoid quick dopamine hits like scrolling through social media or binge-watching short videos.
3. Optimize Your Diet
- Reduce your intake of ultra-processed foods and sugar.
- Focus on whole, nutrient-dense foods that stabilize your energy levels and support brain health.
4. Create a Morning Routine
- Start your day with effortful activities like making your bed, brushing your teeth, and splashing cold water on your face.
- Avoid checking your phone for at least 15-30 minutes after waking up to prevent an early dopamine spike.
5. Incorporate Physical Activity
- Exercise is one of the most effective ways to boost dopamine and reduce stress.
- Aim for at least 30 minutes of moderate exercise each day, whether it’s walking, running, or strength training.
6. Practice Strategic Boredom
- Allow yourself to experience boredom without reaching for your phone. This helps your brain reset and regain its ability to focus.
- Use this time to engage in creative activities or simply reflect on your day.
The Power of Laughter and Connection
In addition to managing dopamine, it’s important to nurture other neurotransmitters like oxytocin, serotonin, and endorphins. These chemicals play a key role in our overall well-being and can help counteract the negative effects of overstimulation.
Key Takeaway: Laughter is one of the most powerful ways to boost endorphins and reduce stress. However, many of us are lacking in genuine, physical laughter due to our isolated, screen-focused lifestyles.
TJ Power recommends creating “laughter environments” by spending time with loved ones, attending comedy shows, or engaging in playful activities. These moments of connection and joy can have a profound impact on your mental health and overall happiness.
The Importance of Discipline and Delayed Gratification
In a world filled with instant gratification, discipline is more important than ever. TJ Power emphasizes that living a disciplined life is the key to long-term happiness and fulfillment.
Key Takeaway: Discipline equals freedom. By setting boundaries and prioritizing effortful activities, you can break free from the cycle of dopamine spikes and crashes, leading to a more balanced and fulfilling life.
Final Thoughts: Reclaiming Your Brain Chemistry
Our modern lifestyle has created a perfect storm of overstimulation, poor diet, and instant gratification, leading to low mood, lack of focus, and low energy. However, by understanding the science behind these challenges and implementing practical strategies, you can reclaim your brain chemistry and improve your overall well-being.
Key Takeaway: The most important thing you can do is focus on balancing your dopamine levels. By reducing quick dopamine hits and prioritizing slow, effortful activities, you can create a more fulfilling and rewarding life.
If you’re ready to take control of your mental health, start by setting boundaries with social media, optimizing your diet, and incorporating physical activity into your daily routine. Remember, small changes can lead to big results over time.
