Tired of Afternoon Slumps?
Vitality101 Newsletter
Hello Reader,
Drowsiness after lunch is a natural part of your body's "rest and digest" process, often referred to as a "circadian dip." However, with a few simple and healthy strategies, you can minimize these midday energy slumps and stay alert throughout the day.
What Are Circadian Dips?
Circadian dips are natural fluctuations in energy levels that regulate your body's internal clock, influencing your sleep-wake cycle throughout the day.
How Does the Circadian System function, and Where Do Circadian Dips Fit Into It?
The brain's biological clock is regulated by several key control centers, collectively known as the pineal-hypothalamic-pituitary axis. This system is designed to optimize energy levels during productive periods while allowing the body to rest, digest, and recover at other times.

Fibromyalgia Pain Might Start in Spinal Cord, Helping Explain Chronic Pain in FMS
A study involving 31 participants offers new insight into why chronic pain is so prevalent in fibromyalgia.
Fibromyalgia involves more than eight key types of pain—making it an excellent model for studying pain management as a whole. One critical factor in both fibromyalgia and chronic pain is the brain's role in amplifying pain signals. This latest research explores how pain is specifically intensified in the spinal cord of fibromyalgia patients.
Under normal circumstances, when a sensation is repeated, the spinal cord gradually reduces its response, helping the body ignore persistent minor irritations. However, this study reveals that in fibromyalgia, this natural dampening effect doesn’t occur. Instead, pain signals continue unchecked, intensifying over time. This prolonged signaling leads to heightened pain perception in the brain, a phenomenon known as central sensitization—sometimes referred to as "brain pain"—which is linked to microglial activation, the process where immune cells in the brain contribute to persistent pain and inflammation.
Reader Feedback on New PEA Supplement
I've begun to receive feedback from readers on the new PEA supplement that we announced recently, and responses have been quite remarkable. Four out of five people who've tried it said they are feeling better. Some said that following my recommendation to take a higher dose of 1,200-2,400 mg per day for the first three months before dropping to the normal 300-600 mg actually did help them get optimal results. Below is a sample of two comments I received:
"PEA has made a huge difference! I started taking it within a week of your article last fall. I’m at about four months. For the first time in six years, I am walking/hiking daily and doing my simple strengthening exercises. I keep building my strength. Very exciting!"
— Thank you! Heather
"Dear Dr. T.
I had been experiencing LC for over 2 years. When I read your recommendation of PEA in the fall of last year I immediately ordered 3 bottles. I did not have to wait even 30 days for the result — it was overnight! It has changed my life!
I cannot thank you enough."
— Gratefully, Arabella
