Your body doesn’t know you’ve “left” the office. Here’s how to actually switch off.

You close your laptop. You eat dinner. You lie in bed.

And then — ping. One email. A Slack message. A “quick question” from a colleague who apparently has no concept of time zones or human rest.

And just like that, your brain is back in work mode.

Sound familiar?

See, the problem is not the notification. The problem is cortisol.

What is cortisol and why is it ruining your evenings?

Cortisol is your body’s primary stress hormone. It’s supposed to peak in the morning — sharp, alert, ready to take on the day — and gradually fall as the evening approaches, signalling to your body: okay, we’re winding down now.

But when you’re answering work emails at 10 PM, checking if your manager responded, refreshing your inbox “just once more”, your brain interprets that as a threat. A task. A responsibility. It tells your adrenal glands: We are not done yet. Keep going.

So cortisol stays elevated. Your nervous system stays switched on. Your body, which was supposed to be preparing for deep, restorative sleep, is still running a background programme, just like how apps run in the background on your phone. It drains the battery, right? Use the same logic here. Don’t you feel drained when you wake up? Come on, do not lie to yourself.

And here’s where it gets really interesting for those of you managing diabetes, cholesterol, or stubborn weight.

Chronically elevated cortisol directly raises blood sugar levels because cortisol’s original job was to prepare you for danger by flooding your system with glucose. No tiger in sight, but your liver doesn’t know that. It releases glucose anyway.

High cortisol also disrupts fat metabolism. Specifically, it promotes fat storage around the abdomen, impairs insulin sensitivity, and — yes — drives up LDL cholesterol. So if you’ve been eating clean, exercising regularly, and still wondering why your numbers aren’t moving as fast as expected? Your evening cortisol levels might be the invisible saboteur.

Weight loss also stalls when cortisol is chronically elevated, because your body interprets the stress as an emergency and holds onto fat as a survival strategy. You can eat well all day and undo the hormonal groundwork with two hours of anxious screen time at night.

So what do you actually do about it?

The trick is to stop trying to “force yourself” to relax — and instead build a transition ritual that tells your brain: work is over. This is a different chapter of the day.

Your brain responds to cues. Give it consistent ones. Trust me, I have tried this and it works. 15 hour workdays with long travel hours are not easy for your body to cope. The least you can do is give it an environment to rest.

Here is a simple routine you can start tonight:

1. Dim the lights in your home – Bright light = daytime = alertness. This is biology, not aesthetic. Dim the lights 30–45 minutes before bed and your melatonin production actually begins. One switch. That’s all.

2. Change your clothes – This one is underrated. The moment you change out of your “work clothes” (even if you were working from home in a t-shirt), you are physically signalling a shift. Different clothes = different mode. Your brain notices.

3. Brush your teeth and wash your face – Not just hygiene — this is ritual. These are acts that mark an ending. You’ve been doing this before sleep since childhood. Your nervous system already associates it with “we’re done for the day.”

4. Put on some calm music or omkara in the background – Sound is one of the fastest ways to shift your nervous system state. Low frequency, slow tempo music — or the simple resonance of Om chanting — activates the parasympathetic nervous system. The one in charge of rest, digest, and repair. Two minutes of this does more than you think.

5. Leave your phone outside the room –  If this feels too extreme, at minimum switch it to greyscale mode. A black and white screen removes the visual stimulation that keeps your brain hooked. The colours in apps are literally designed to grab your attention. Remove the weapon.

6. Do 5 minutes of diaphragmatic breathing – Breathe in slowly through your nose for 4 counts, let your belly rise (not your chest), hold for 2, exhale slowly for 6–8 counts. This directly activates your vagus nerve — your body’s natural “calm down” switch. It lowers cortisol measurably. It slows your heart rate. It tells your nervous system: the emergency is over.

7. Massage your feet – This is not pampering. Foot massage stimulates pressure points connected to the nervous system, reduces cortisol, and improves circulation. Five minutes with some coconut or sesame oil. Your sleep quality will surprise you.

8. Go to bed at the same time every night – Your cortisol rhythm is also a circadian rhythm. Consistency is what trains it. Your body learns when to start lowering cortisol if you give it a reliable pattern to work with.

The emails will be there tomorrow.

Nothing that arrives in your inbox at 11 PM requires a response before sunrise. And if it genuinely does — that is a workload conversation you need to have with your manager, not a problem to solve with your health.

Your colleagues are not losing sleep over your blood sugar or cholesterol levels. You shouldn’t be losing sleep over their deadlines.

Protect your evenings like you protect your meals because what happens in the hour before you sleep affects your cortisol, your blood sugar, your cholesterol, and your ability to actually show up well tomorrow. People who switch off properly at night are more productive, more clear-headed, and more in control — not less.

So dim the lights. Change your clothes. Put the phone down.

Your body has been waiting all day for you to give it this one instruction: we’re safe. We can rest now.

Let it.
