It had been in an icy pool on Dartmoor which I found enlightenment: a feeling of utter contentment, of unadulterated physical and mental wellbeing as well as the knowledge that, at the time, all was well because of the universe.
When I lay back, chest-deep in water that even yet in midsummer held a breath-snatching sharpness for my sweaty limbs, I dedicated to shafts of brilliant sunlight breaking via the forest canopy above, together with intensity of birdsong all over.
A difficult eight-mile run from Cadover Bridge up over Shell Top on uneven terrain had brought me here. Yet I felt energised in the place of weary; no muscle aches or stiffness, and my feet felt light. I really could have run that circuit again – probably faster. My mood soared.
“Euphoric’’ may be the word that proponents of a brand new workout – Immersion Fitness – use to spell it out the impression that may be produced through a mixture of hard exercise accompanied by experience of cool water, and I also wouldn't normally disagree.
There clearly was little doubt that chilled water has enormous benefits for any human anatomy. There clearly was a great deal of evidence demonstrating its anti-inflammatory and defense mechanisms stimulatory effects, mood elevation and promotion of fat reduction. Andy Murray and also the England rugby team endure ice baths included in their recovery routine.
We have always enjoyed the “runner’s high”, usually, in my own case, amongst the fifth and seventh mile. But my experience on Dartmoor was more intense. In reality the actual only real time i will recall a comparable sense of such extreme wellbeing was a single day when, as a teen with a broken arm, I sat on a trolley in an A&E department watching the entire world pass by in a blissful haze of intravenous morphine.
Just how can aerobic workout and a dip in a cold river mimic the effects of a strong opiate back at my body? And might i truly replicate this feeling on demand by adopting a brand new exercise regime?
Cold-water immersion is a component regarding the fitness philosophy of fitness expert Nigel Jenkins, the founder of Immersion Fitness. An old physical training instructor for a Commando regiment and a British international cross-country skier, he has got developed a novel method of maintaining fitness with the natural obstacles of Dartmoor – the hills, crags, boulders and waterways – as a rural multigym. It absolutely was Jenkins who led four of us on our challenging run accompanied by a leap into that pool. Later, within the Royal Oak into the village of Meavy, I traded him a pint of Otter for a reason of his approach.
Jenkins is an endurance athlete with a desire for Britain’s wild places that has operate on Dartmoor for “35 years or so”. Constant, physical challenge is really what he lives for. On Millennium Eve he put down at dawn to circumnavigate the moor before joining the celebrations at his local. He ran a distance of 85km whilst the crow flies, with 3,700m ascent, in 18hr 3min. The route has since been named “The Nigel Jenkins Round”.
Jenkins explained if you ask me that his approach was centered on an awareness regarding the ways mankind has evolved. Humans lived as hunter-gatherers for longer than two million years, with a body adapted to survive the challenges that lifestyle involved.
“Our bodies are simply just not created for the 21st-century lifestyle,” Jenkins says. “We need excitement, exertion, stimulation and challenge.” His personal recipe for wellbeing is a mixture of exercise and cold-water immersion in a normal environment and a “Spartan” diet, lower in carbs and saturated in oily fish.
Instinct informs me that he's right, that there surely is synergy here – utilizing the body’s natural reaction to the worries of exercise also to chilled water amplified, a far more profound feeling of euphoria is produced. But as a medical practitioner, i do want to understand what the data is. Even a short contact with cool water, say 20 seconds at 40F (5C), produces a marked response in mental performance because of the launch of a “stress chemical”, noradrenaline, that is both a neurotransmitter and a hormone. Its effect is always to focus the mind and body’s attention on a perceived danger or unusual situation, while also elevating mood. A 60-minute immersion at 57F (14C) causes a five-fold boost in noradrenaline and a simultaneous two-fold jump an additional chemical, dopamine.
It is dopamine that generates the powerful sensation of enjoyment. In order the core temperature associated with the body drops, the mind responds with a cocktail of hormones, neurotransmitters and endorphins to help keep us functioning. In addition happens to create us feel well.
Last February, I took part during the Big Chill Swim in Windermere, where I met the president of a Nordic Swimming Association and asked her why anyone would cut channels within the ice associated with Siberian Sea – as her members do – for any purposes of a swim. “You can run your half marathon and pound your joints to feel well, you can also achieve exactly the same effect by swimming 25 metres in iced water…” she said.
I will be now believing that by combining these activities, we reap the many benefits of both after which some. A cold-water dip is currently section of my daily exercise ritual. That wouldn’t need to feel this good each and every day?
