I’ve developed a real hatred for birds…

They’re always so eager and ready to start the day…

While it’s been hell for me the past 36 hours.

I’ve not slept a wink.

Not too long ago I told myself, “If I fall asleep right now I’ll get 10 hours of sleep.”

“If I fall asleep right now I’ll get 8 hours of sleep…”

“If I fall asleep right now I’ll get 5 hours of sleep…”

“If I fall asleep I can get at least 3 hours of sleep. Just enough to feel minimally rested…”

“I hope I can get at least an hour of nap time before I have to get up for work…”

There’s something particularly unholy about the sunlight filling up my room after hours of lying in bed in a soul-crushing pursuit of trying to fall asleep…

And finally giving up rolling over to cancel my 6am alarm at 5.50am because there’s no chance in hell I can get enough rest in 10 minutes to need an alarm.

Everyone who meets me always tells me I look like hell. Like I just crawled out of a car wreck.

Worse, no one understands what it’s like to have insomnia.

“Just lie down and close your eyes and go to sleep.”

“Have you tried melatonin?”

“Have you heard of sleep hygiene? Just don’t use any screens one hour before bed.”

Yes Steve, I’ve tried everything short of smashing my head against a wall in hopes I knock myself out.

People like to play the one up game when it comes to lack of sleep, and it pisses me off.

What if I told you there’s nothing too mysterious about falling asleep.

I get that everyone’s insomnia is different and what works for me might not work for you.

But if you, like me, were at the edge of desperation, then here’s something that worked for me. It’s about finding your own routine, rhythm and solution (which is not to say that there is a miracle cure to insomnia)

If curing insomnia were that easy, it wouldn’t be a problem for anyone anymore. Right?

The good news is that sleep research is finally taking off.

Even though there is still a lot we don’t know about sleep, we now are able to develop strategies that have helped thousands of people get that sweet, sweet REM they desire.

In this page I will share a little bit about how the body regulates sleep (don’t worry, this won’t be a science class)...

And the 3 things I did that worked for me to regulate my body and finally be able to fall asleep easily.

Are you ready to take the first step towards changing your sleep life?

Yes?

Great! Let’s get started.

A fair warning though…

What I’m about to share with you is what worked specifically for me based on research, reading what has worked for others, and talking to multiple people.

Most people love the idea of a simple solution, but the reality is what works for one person may not work for someone else.

But that also doesn’t mean that what works for someone will definitely not work for someone else. We are different people, but are still humans at the end of the day.

Our bodies work more or less in similar ways.

So, if you follow what I did and commit to it (don’t just half-arse it)...

I am here to show you the way to better, deeper sleep.

What drives us to sleep?

Imagine your body has an internal clock, like a timer set to about 24 hours—which helps you know when it's time to be awake and when it's time to sleep.

This is called Process C (or circadian rhythm) which is influenced by sunlight; so when it gets dark outside in the evening, your brain starts producing a hormone called melatonin, which makes you feel sleepy.

On the other hand, sleep pressure (or Process S) is like a kind of sleep debt that builds up the longer you stay awake.

Adenosine, a chemical in your brain, accumulates as you stay awake, and the higher its levels, the more tired you feel.

When you finally sleep, adenosine levels drop, and you wake up feeling refreshed.

Now, there is a neurotransmitter called GABA that is like a brake for your brain. It helps slow things down and prepares your body for sleep.

When it's active, you start feeling relaxed and ready for bed. But during the day, dopamine and norepinephrine act like the gas pedals that keep you awake and alert.

They make you feel motivated and focused, helping you stay active.

In short, your sleepiness-wakefulness cycle is like a delicate dance between Process C, guided by sunlight and melatonin, and Process S, influenced by sleep pressure and adenosine.

GABA gets you ready for sleep, while dopamine and norepinephrine keep you awake and energetic during the day.

It's a balance between these processes and neurotransmitters that determines when you feel alert and when you're ready to get some well-deserved rest.

There are no shortcuts to better sleep

Trust me when I say this. As someone who has experienced insomnia, sleeping well requires discipline.

I know people who can close their eyes and literally knock out in seconds. And when I was younger, I used to be envious of that.

Over time I’ve learned to accept that not everyone is built the same. And so I developed habits that helped me sleep better.

But before that, I tried all sorts of shortcuts. And none of them worked.

Melatonin, for example, didn’t work for me. And turns out it’s because my insomnia was not linked to low serotonin levels.

Taking melatonin only resulted in worse sleep as my body became very tense and restless at night. I also had weird vivid dreams (sometimes nightmares) that weren’t fun.

Plus, taking melatonin when you don’t need it can deplete natural melatonin production in the long run, causing you more sleep problems over time.

But what about sleeping pills? Despite their name, they don’t actually help you sleep. They have more of a sedative effect, like a tranquilizer.

Benzodiazepines have been shown to lose effectiveness in as little as 3 weeks, and resulting in shallow, non restful sleep.

They can also result in dependency, causing withdrawal symptoms like rebound insomnia and anxiety, and result in cognitive slowing during the day.

They’re usually prescribed as stopgap solutions for extreme cases where sleep is absolutely necessary, and not as medication to take on a nightly basis.

So how do I sleep better?

What if I told you there’s a “button” in your brain that you can hit to reset your sleep cycle.

It’s like when a machine starts malfunctioning and you just need to turn it off and back on again to restart the process.

In the case of your body, it’s a 2-step process: Stabilize and Reset

First, stabilize Process C. All you need to do is sleep and wake up at the same time every single day for 30 days.

Sounds simple but that means no more late nights out. No more sleeping in on the weekends. And no midday naps.

No matter how tired you are, you have to get out of bed and stay awake through the day.

And if you want to really get the best results:

Avoid alcohol. Alcohol disrupts your neurotransmitters in your brain and affects your sleep
Have 3 meals at the same time every single day. Your last meal (dinner) should be at least 2-3 hours before bed time
Exercise 6 times a week, at least 1 hour a day. You can do strength training or go for a run—whatever your preference is, just as long as you get some exercise.

Once you’ve stabilized your Process C, it’s time for the next step… reset Process S.

To do that you need to jumpstart the norepinephrine and dopamine release in the morning, then let adenosine build up sleep pressure throughout the day.

After 30 days of sticking to this routine, your body will get used to producing wakefulness neurotransmitters at a specific time in the day and releasing sleepiness chemicals throughout the day until your bedtime.

So how do you do this in a safe and natural way—without supplements or medication?

The safe, proven way to sleep better

This method has recently gained popularity and is used by professional athletes, biohackers and even promoted by doctors and experts as a way to improve focus and energy levels during the day.

What I am particularly interested in is how improving energy levels and focus can lead to better sleep.

You see, wakefulness and sleepiness are two sides of the same coin.

They are yin and yang. Improving one aspect will naturally have a positive effect on the other.

This method that I am referring to is cold plunging.

Researchers have studied how cold plunging leads to improved focus and energy that lasts throughout the day, and found that it helps regulate the two neurotransmitters responsible for wakefulness and focus: norepinephrine and dopamine.

When the body is exposed to the cold water, there is a strong vasoconstriction reaction of the skin which helps reduce pain. This is partly caused by norepinephrine release and other neurotransmitters in an effort to reduce heat loss [1].

A paper published in 2022 studying the health effects of cold plunging found that the acute stress caused by cold water immersion increases norepinephrine in the brain[2].

An effect of norepinephrine release is alertness and increased focus.

Many users of cold plunging have reported that this effect lasts for hours after they get out of the cold water.

And you don’t even have to do it for a long time. You too can enjoy the benefits as long as the water is under 10°C and your body is submerged for at least 3-5 minutes.

Cold plunge without the fuss and frustration

“Can’t I just use bags of ice and a barrel or a kiddy pool?”

Sure you can.

But would you want to have to inflate and fill the tub full of water, while waiting hours for water to freeze.

Or, even having to drive to the store and lug large bags of ice back just to prepare your ice bath.

Using it for a couple of minutes, and then draining the water.

Imagine doing that every day. What could be just a 3-5 minute cold plunge session would probably take at least an hour.

“I would leave the water there so I don’t have to drain it.”

Well, that’s what I thought so too before I owned a cold plunge. But after owning one, and seeing how easily hair, dust, grime and algae can build up, leaving the water there isn’t an option for me.

There’s no way I would want to cold plunge in dirty water.

That’s why when I discovered this solution, I knew I had to try it immediately to see if it was really that simple. And I never looked back since.

Introducing the Supertub

It’s the easiest way to get a cold plunge.

The Supertub keeps your ice bath super cold and super clean all day.

Want to cold plunge first thing in the morning? Just take off the lid and get in right away.

No set up or waiting time needed.

That’s because the Supertub is powered by the Permafrost™ chiller—a powerful cooling system that can cool water down to a chilly 37°F (or 3°C) and keep it there all day.

Not only that, the Supertub also comes with a built-in, commercial-grade ozone generator that eliminates microbes and keeps water clean and fresh (unlike UV filters which only does the former but doesn’t remove cloudiness or odors).

Finally it also has a 15-micron filter to filter out dirt, dust, hair and debris from the water automatically. A great choice if you don’t want to be sitting in a dirty tub every time you cold plunge.

These 3 features alone makes the Supertub superior to your own DIY ice baths.

So if you are ready to improve your sleep, energy and focus—and change your life, try the Supertub today.

I love my Supertub

Cold plunging is one of my favoritest thing to do so I was very excited to receive my Supertub from Hydragun. I was pleasantly surprised at how easy it was to set up and use - I can easily set the temperature with a high level of accuracy which I won't be able to get with manual tubs. I do cold plunge 3 times a week and I always feel energized after - Improves my productivity at work and helped me stay mentally clear throughout the day.

No regrets

The Supertub is an intensive experience. 3 minutes immersed in 7 degrees Celsius water is a shock to my system, but the after effects is great - almost like taking a double espresso Red Bull cocktail. The benefits behind cold immersion are well documented as well.

The sleek set up of the Supertub and chiller takes up only a small space in the balcony and the electricity maintenance is small, akin to having a small refrigerator.

I think this is a must-have for anyone intending to up their game.

Highly recommend the Supertub!

I’m the last person I would have thought to be enamoured with cold therapy, but here we are. When the likes of Lebron James, Floyd Mayweather, Christiano Ronaldo and Usain Bolt are doing it, you don’t question these greats. And what a journey it has been.

The tub is seemingly designed in a very simple manner, but yet things work as they should, in ways that shows thought has been put into every aspect of it. Clean sterile material for the body, outlet to drain water, simple clip-on cover are just some of the examples. Keeping it hooked onto a power outlet can’t be simple enough and the machine does a great job of reading the ambient temperature and responding extremely quickly to changes in the temperature. It does exactly what it is supposed to do, at a very competitive price to boot.

Cryotherapy, although something that I have only embarked on recently, has been something that has always been around since men have been exploring the colder regions of the Earth. Not something I can usually experience as a Singaporean (we put a capital T in tropical climate) but this has proven to show numerous benefits, both physically and mentally. Not only are post gym recoveries much more manageable, but there is almost a zen-like headspace of focus after emerging out of the cold waters. Energy levels, focus, and drive are through the roof as I struggle to find and understand the mechanics of why this works; it just does.

The Supertub has become a routine that I’ve integrated into my daily life, from once a week to thrice, and perhaps more subsequently. It’s great for a little pick me up during the middle of the day to recharge and focus, as my job as a realtor requires my social energy and focus to be at optimum whenever I am running my sales. There are probably much more benefits to my body that I am not conscious about, and that thought simply excites me!

Try the Supertub before you commit

Every Supertub comes with a 30-day risk-free promise. That means you can try it for 30 days, and if you find that it’s not for you, simply send us an email and they’ll arrange a return.

Just remember to send it back nicely packed and dry.

Their customer service team is available every day and will respond quickly to your queries should you have any questions.

Is the Supertub for everyone?

That’s a very important question. First things first, if you have a medical condition and are unsure, do check with your physician.

But for most people, cold plunging can benefit their lives tremendously.

It might sound difficult. And extremely uncomfortable. But for those who believe in stepping out of their comfort zone, there is a light waiting at the end of the tunnel.

Developing mental resilience, grit and the habit to push yourself to do difficult things is something not many people do often.

And even though it might feel difficult the first few times, it will eventually get easier. Trust me. You will realize most of the fear and anxiety comes from the anticipation of getting in.

But once you’re sitting in the icy cold water, you’ll feel all the stress and anxiety leave.

“It’s not as bad as I thought it’d be.” That’s what everyone says once they’ve tried it. And I’m confident you’ll feel the same way eventually

Because building grit and the discipline to accomplish difficult things is like a muscle. The more you train it, the stronger you become, and the easier it becomes.

If you’d rather stick to your comfort zone and go the easy route, then the Supertub definitely isn’t for you. It’s a personal choice.

But if you’re someone who believes in stepping out of your comfort zone, and want to train your grit muscle mentally and physically…

Then try the Supertub today.
