💡 Today's Study: "Circadian Variation in Vascular Function and Regenerative Capacity in Healthy Humans" by Dr. Ibhar Al Mheid, Emory University (2014)
🔗 Source: Journal of the American Heart Association - JAHA Full Study PDF
❓Who Did This Research and When?
This study was done by Dr. Ibhar Al Mheid and a team of doctors and scientists from Emory University School of Medicine in Atlanta, Georgia, USA.
The paper was published in 2014 in the Journal of the American Heart Association.
❓Where Exactly Was the Study Done?
The tests were done at Emory University Hospital and the Atlanta Clinical and Translational Science Institute
❓Is Emory a Good University?
Yes. Emory is one of the top research universities in the United States. They are known worldwide for their work in health and medicine.
❓Who Paid for the Research?
This study was funded by the Marcus and Woodruff Foundations, Georgia Tech/Emory Predictive Health Institute, and the U.S. National Institutes of Health (NIH).
🧪 What Is This Research About?
The study looked at how blood vessel function and your body’s natural repair cells (called progenitor cells) change throughout the day in healthy people.
They checked:
-
How flexible or stiff blood vessels are.
-
How well the blood flows.
-
How many repair cells are in your blood.
-
When these things are best and worst.
These body functions are important for people who use EMS (Electrical Muscle Stimulation), because EMS may improve blood flow and help the body work better when timing is right.
❓Who Were the People Studied?
15 healthy adults between the ages of 21 and 67. They didn’t smoke, didn’t take medications, and didn’t have diabetes, high blood pressure, or high cholesterol.
❓How Was the Research Done?
The researchers tested the participants 7 times in 24 hours—at 8 AM, noon, 4 PM, 8 PM, midnight, 4 AM, and the next day at 8 AM.
They checked:
-
Blood flow (using ultrasound)
-
Vessel stiffness
-
Number of repair cells in blood
-
How active those repair cells were
📈 What Did They Find? (Only Good News for EMS Users)
🟢 Best Blood Flow:
Happened at midnight.
🟠 Worst Blood Flow:
Happened at 8 AM and 8 PM.
🟢 Most Repair Cells:
Happened at 8 PM.
🟠 Least Repair Cells:
Happened at 8 AM.
🟢 Most Active Repair Cells:
Happened at midnight.
🟠 Least Active Repair Cells:
Happened at 8 AM.
🟢 Softest Arteries (Best Condition):
Midnight and 4 PM
🟠 Stiffest Arteries (Worst Condition):
8 AM
🔍 Specific Proof from the Study:
-
Repair cells (CD34+/CD133+) were 44% higher at 8 PM than in the morning.
-
Blood flow improved 30.4% more at midnight compared to the morning.
-
Arterial stiffness dropped 65% at midnight compared to its peak at 8 AM.
🤖 Why Does This Matter for EMS Device Users?
Although this study didn’t use EMS, it looked at something EMS devices can support—blood flow and vascular function. EMS is often used to help promote circulation and muscle recovery. This study shows your body naturally improves these functions in the late evening and at night. So if you're using EMS at night, you might be tapping into your body’s natural peak.
It’s also good to know: blood flow is naturally worse in the early morning, which might explain why some people feel stiff or slow when waking up.
🧠 How This Study Helps You
-
You now know that evening EMS sessions may match your body’s best time for blood vessel health.
-
If you're recovering from soreness or looking to relax muscles, evening EMS may feel more effective.
-
If you're new to EMS, don’t worry if it feels less effective in the morning. Your blood flow is naturally lower then.
