Mastering Self Reliance At Sea
I have never seen so many high blood pressures as I have this year!
I even extended the “normal limits” for Blood Pressure (BP) in my medical training classes.
At one stage I thought I would have to send half the class to their GP, I’d be left with no students
It’s pretty normal to see 190/100 in our world.
If you eat well, work out & even “meditate” why is your BP so high?
To put it bluntly, stress is quietly raising your blood pressure and impacting your overall health.
High blood pressure can lead to serious issues like heart disease and stroke, but the good news is that you can manage it by regulating your nervous system and lowering cortisol levels.
Here’s how it works:
When you’re stressed, your body releases cortisol, the “stress hormone.” In small doses, cortisol helps you handle immediate challenges.
But when stress becomes chronic, cortisol stays elevated, keeping your nervous system in a constant state of high alert. This leads to persistently high blood pressure, which is a serious risk for your heart.
Signs of high blood pressure you should never ignore:
- Persistent Headaches
- Fatigue and Tiredness
- Chest Pain or Discomfort
- Shortness of Breath
- Blurred Vision
- Frequent Nosebleeds
- Pounding in Your Chest, Neck, or Ears
So, how do we tackle this? By regulating cortisol and calming your nervous system.
I believe a lot of stess is being caused by artificial light, Wi-Fi and being surgically attached to a device at all times.
This has to stop.
Here’s how:
1. Morning Sunlight NAKED Without Sunglasses
Or ear phones / buds:
Start your day with 10-15 minutes of sunlight & exposure—without sunglasses. And SILENCE, appreciate the sounds of the environment & breathe.
This simple habit helps regulate your circadian rhythm, lower cortisol, and keep your blood pressure in check.
2. Unplug at Night: Turn off Wi-Fi and keep your phone out of the bedroom. EMFs disrupt your sleep, keeping cortisol levels high.
A tech-free, blackout room helps your nervous system reset, leading to better sleep and lower blood pressure.
3. Limit Screen Time: More screen time equals more stress.
Try a digital detox each day, even just for 2 hours, to give your nervous system a break and lower your blood pressure.
Try and stop screen time 2 - 3 hours before bed- this is a BIG ONE (necessary for melatonin production)
4. Declutter Your Mind
A clean, clutter-free environment helps reduce stress and calm your nervous system. It’s the same with your mind. Write down all the things that stress you each night, get it out if your head!
Close the note book and sleep better, knowing you left your worries on a piece of paper for tomorrow!
5. Soak Up Sunlight During the Day:
Open the blinds and let the sunlight in. Natural light helps regulate cortisol and keeps your nervous system balanced, which in turn helps lower your blood pressure. Take you sunglasses off for a while and let the real light soak in.
Bottom line:
Stress doesn’t just make you feel bad—it can seriously impact your health. By focusing on ways to regulate cortisol and calm your nervous system, you can protect your heart and live a healthier, longer life.
