Wired at 11pm, dead at 7am? Your cortisol curve might be running backwards.

Exhausted executives are not doing the wrong things. They are doing them at the wrong hours.

I spent 16 years on a trading floor. Markets have hours for a reason. Trade outside them and you get hurt. Everyone respected that.

Then we went home and treated our bodies like the rules did not apply.

Your body keeps hours too. Cortisol, digestion, blood sugar, body temperature — all of it runs on a 24-hour cycle.

The same meal. The same workout. The same coffee. All land completely differently depending on when they arrive.

Today I want to show you the schedule your body is actually running, what years of ignoring it does to your stress hormones, and the at-home test I use with clients to see exactly where the day went wrong.

The schedule your body is actually running

First hour awake: light first, protein before coffee

• Daylight in your eyes sets the entire day's cortisol curve. Miss it, and the curve arrives late and trust me, you will feel that at 11pm as a second wind you never asked for

• Caffeine on an empty stomach borrows sharpness from your afternoon, then hands it back as a crash

• The move: 10 minutes outside before the inbox (grey sky counts), then protein first, coffee after

Late morning: spend your peak on real work

• This is your genuine high-capacity window for hard thinking. Most people spend it on email

• The move: protect one 90-minute block for the work that actually moves things

Midday: front-load the food

• Your glucose control is best earlier in the day. The identical dinner at 9pm produces a worse response than it would at 1pm

• The move: make lunch the biggest meal when you can!

Mid-afternoon: walk the dip

• The dip is designed in. It is not a malfunction. Fighting it with sugar and a third coffee costs you tonight's deep sleep

• The move: 10 minutes of walking beats both

Last two hours: dim the runway

• Bright light late tells your brain the day is starting over. Melatonin waits, sleep shortens, tomorrow starts in debt

• The move: dim the house after dinner. It is the runway, not the terminal

Unfortunately, knowing the schedule is not always enough

If you have run against your clock for years, you have probably already tried:

• Earlier bedtimes that ended with you staring at the ceiling

• The sleep hygiene checklist and the magnesium before bed

• Cutting coffee for one miserable week, then giving up

• More discipline, which is to say, more willpower spent fighting your own biology

Here is why none of it stuck. After enough years of trading outside your body's hours, your cortisol curve itself changes shape.

A healthy cortisol curve looks like this:

• High in the morning, to lift you into the day

• Tapering through the afternoon

• Low at night, so sleep can do its repair work

The curve I routinely see in people who have run against their clock for years:

• Flat in the morning

• Elevated at night. Wired exactly when you should be winding down

Which is exactly why the coffee feels mandatory and 11pm feels like a second wind. You are not undisciplined. Your cortisol curve is running backwards, and no checklist can fix a curve it has never seen.

This is why I run cortisol testing with my clients: a functional at-home panel. Once we can see where the curve is broken, we know which hours to fix first and in what order. The vague project of "fixing my energy" becomes a short, specific list. That is the difference between guessing for a year and results in weeks.

What this looks like when it gets fixed

Let me make it concrete. Here is the picture I see in most hedge fund executives I work with, especially portfolio managers trading foreign exchange — a market that never closes.

Where they usually start:

• London open, New York session, Tokyo positions checked at midnight — the "day" has no edges

• Usually 5 coffees, the first one non-negotiable

• A crash mid-afternoon, a second wind at 11pm, sleep in fragments

• Weekends spent recovering instead of living

What I do for them:

• Run the four-point cortisol panel across one normal trading day, paired with a mineral analysis

• Find the classic flipped curve: flat in the morning, elevated at night, with the minerals that help cortisol behave running low

• Rebuild the day around their hours

• Add targeted therapeutic supplements at strategic times (nope, not the ones you get on Amazon!)

• Keep the market schedule. Change the order of the signals around it

Because here is the part shift workers and global-markets people never hear: your body cares less about what the clock says than about consistency and the order of the signals it receives. You cannot move Tokyo. You can move everything around it.

Where they usually land, a couple of months in:

• 5 coffees down to 2, by choice, not by rule

• The 3pm crash stops wreaking havoc on the day

• Asleep within 20 minutes, waking before the alarm

• The retest showing the curve rising in the morning again and tapering at night

Same job. Same markets. Different clock.

The move: if your day has no edges, the schedule above still applies — it just anchors to your wake time instead of sunrise.

The bottom line

You cannot out-discipline your own clock. But you can learn to trade the hours you are actually open, and you do not have to guess which ones those are.

Your body has been keeping the minutes this whole time. The test just lets us read them.

Which one hits hardest for you: the mandatory morning coffee, the 3pm crash, or the 11pm second wind? If that picture looks anything like your day, mapping your curve is exactly the work I do with clients, and I can point you to the right next step.
