Always Wired but Tired?
5 Things You Need to Know About Cortisol (and How to Bring It Back Down)
You wake up already tense. Your jaw is tight before your feet hit the floor. By 3 p.m. you're wired and exhausted at the same time. Then you lie down at night, and your mind won't shut off.
That's not just "a stressful week." That's cortisol, your stress hormone, stuck in the "on" position.
And you're not alone. In a national survey, 76% of adults said they had at least one stress symptom in the last month, like headaches, fatigue, or trouble sleeping. [1]
The good news? Cortisol can work for you again. Here are 5 things you need to know about cortisol, and how to help your body bring it back down.
1. Cortisol Isn't the Enemy. A Broken Rhythm Is.
Cortisol is supposed to rise and fall every day, like the sun. [2]
Morning: It rises to wake you up and give you energy
Night: It drops low so you can relax and fall asleep
That's cortisol working for you.
The problem starts when that rhythm flips. You drag yourself out of bed in the morning, then feel wide awake at night. Your body never gets the signal to switch off.
Signs your cortisol may be working against you:
Feeling "wired but tired" all day
A hard crash in the afternoon
A racing mind when your head hits the pillow
Waking up at 2 or 3 a.m. for no reason
Cravings for sugar and comfort food
Stubborn weight around your middle
2. Modern Life Keeps Your Stress Alarm Ringing
Your body can't tell the difference between a bear chasing you and a stressful email. Both set off the same alarm.
Back in the day, the alarm went off, then shut off. Today, it never gets the chance to stop. Here are the everyday habits that keep it ringing:
Grabbing your phone before your feet hit the floor
Back-to-back deadlines and a to-do list that never ends
Bright screens late into the night
Skipping meals and running on coffee
Never fully switching off, even on the weekend
Dr. Andrew Huberman, a Stanford brain scientist, often says to get outside light early in the day. It helps set your body clock. [3] Most of us do the opposite: dim mornings indoors, and bright screens at midnight.
3. One Bad Night Raises Tomorrow Night's Cortisol
Here's the cycle that traps so many hard-working Americans.
In one study, just one short night of sleep made cortisol 37% higher the next evening. [4] A full night without sleep made it 45% higher. And the body's "off" time for cortisol got pushed back by at least an hour.
So you sleep badly. Your cortisol stays high the next night. So you sleep badly again.
That afternoon coffee doesn't help either. Even daily coffee drinkers saw cortisol climb again after an early-afternoon cup. It stayed up into the evening. [2]
Help Your Body Switch Off the Stress Alarm With One Simple Daily Habit
You know the signs. Wired at night. Dragging in the morning. Snapping at the people you love because you're running on empty.
The real problem isn't that you're weak or "bad at stress." It's that your body is low on the mineral it uses to calm the alarm.
Our Daily Magnesium gives you 420mg of magnesium from 4 easy-to-absorb forms, plus Vitamin D3 and K2. It helps your body handle stress and calm down. So you can sleep deep and wake up ready.

4. Stress Drains Your Magnesium Levels
This is the part almost nobody talks about.
When you're stressed, your body flushes out more magnesium. And when magnesium runs low, your body reacts to stress even more. Researchers call it a "vicious circle." [5]
Here's how it works:
Stress makes you lose magnesium
Low magnesium makes your body more sensitive to stress
More stress makes you lose even more magnesium
And most of us start out behind. About half of Americans don't get enough, even with supplements. [6]
So every stressful day digs the hole a little deeper.
5. Magnesium Helps Bring Cortisol Back Down
Here's the good news. You can break the cycle.
In a 24-week study, adults took magnesium split across breakfast, lunch, and dinner. By the end, their cortisol output was lower than the placebo group's. [7] Magnesium also boosted an enzyme that helps your body switch cortisol off.
In another study, older adults with poor sleep took magnesium for 8 weeks. Their cortisol went down, and they fell asleep faster. [8]
Magnesium also helps power GABA, your brain's natural "calm down" signal. Without enough of it, your body stays stuck in alert mode.
That's why Daily Magnesium is made to be taken one capsule with each meal, the same simple, steady way.
Now you know what keeps your cortisol stuck "on"... here's the easiest way to help your body turn it off.
"Best magnesium I've ever taken! And I have tried many over the years... I have really noticed an improvement in my sleep quality."
