Blast from the Past

The stress-skin connection is becoming better understood by science. New research shows that the nervous system and stress affect inflammatory skin conditions in humans – something we all understand anecdotally but often forget when trying to treat skin problems like acne, psoriasis, eczema, and more. After all, has a dermatologist ever told you to do yoga to help cure your acne? 

As explained in this article: 

Many types of cells in the skin, including immune cells and endothelial cells (cells that line blood vessels), can be regulated by neuropeptides and neurotransmitters, which are chemicals released by the skin’s nerve endings. Stress can result in the skin’s nerve endings releasing an increased level of these chemicals. When this occurs, it can affect how and at what level our body responds to many important functions, such as sensation and control of blood flow, and can contribute to the symptoms of stress that we feel. In addition, the release of these chemicals can lead to inflammation of the skin.

This is a great overview of how both acute and chronic stress can exacerbate skin conditions and lead to flare ups, even if other lifestyle factors like diet and skincare are well managed. I’ve talked about the Gut-Brain-Skin Axis before, and have explained how stress can affect both our gut health and our skin health in different ways. And while a nutrient-dense diet is extremely beneficial for addressing chronic skin issues, like many other chronic conditions, even the best diet can’t account for the damage and inflammation caused by poorly managed stress.

So if you’re trying to get frustrating skin conditions under control and have overhauled your diet and skincare routine without getting the results you were hoping for, you may need to consider the role that stress plays in these conditions. It’s crucial to practice evidence-based stress management techniques to take a more holistic approach to skin health. Your skin – and the rest of your body – will thank you!

Research Report

Worth a Look

  • Take a vacation, stay-cation or mental holiday and your brain will thank you.

  • Consistency is key to maximum health benefits from a running regimen, even if running just 5 minutes a day.

For the Foodies

  1. interesting article. stress affects EVERYTHING.

    the article makes me wonder about another under-appreciated, under-researched factor in skin health: the ecology of the skin micro-biome.

    I rather suspect the the coming years will see a lot more work on this, and we will discover a lot more complex interrelationships which suggest lifestyle factors as more efficacious approaches to long term improvement.

    Any frequent reader here will be aware that science is now learning that certain dietary habits and use of antibiotics can sometime bring about short term improvements to many health problems, but these practices can also lead to long term imbalances in the gut micro-biome that cause serious long term health problems.

    In the same way, I suspect we will discover that lifestyle habits such as frequent cleansing and exposure to various personal care products and medical treatments with topical antibacterials and antibiotics may help certain things in the short run, but can lead to long term imbalances in a micro-biome whose importance to overall health in ways previously not understood.

    I also often wonder about how much the skin micro-biome interacts with the gut. Since going paleo 3-4 years ago, my gut seems to have re-established a much more natural diversity and stability, and my general health is vastly improved.

    That said, I still am rather vulnerable to skin fungal imbalances, chiefly tinea versicola in hotter weather. I suspect there is some linkage between micro-biota of the gut and the skin, indirectly through the immune system and other such pathways, or directly thought the mouth (another vastly complex and under-studied microbial environment!).

    Chris, I wonder if you’ve any thoughts on this or are aware of any interest research or theories. Have any big-data studies projects such as the human micro biome project looked into correlations and interactions between gut and skin?

  2. So happy to be a part of the roundup again! Can’t wait to try the other recipes as well, especially that avocado, cucumber and pistachio salad!

  3. I struggled with acne for almost 20 of my adult years (5 of those on a Paleo diet) and have recently started to have clear skin. The difference? Going AIP for my Hashimoto’s, taking zinc, and getting acupuncture for stress. I think acupuncture was the key.

  4. LeBron James and other players’ weight loss are probably from stopping HGH, because the NBA is will start testing for it now.

  5. I didn’t have rosacea until menopause and the hot flashes. Now I control both with adequate fat and black currant seed oil (an anti-inflammatory).

    They say coconut oil works wonders on the brain, and they’re RIGHT–hot flashes are basically the body’s cry for fuel, so I feed it.

    • Am I correct in thinking if I use coconut oil it will reduce hot flushes? what forms can this be used in? thanks helen
