Is it a village or a town I wonder?
Longridge was once a village centred on stone quarries and cotton mills. But that was long ago, there has been steady development in the last 50 years, until it is now a dormitory town of Preston.
The population in 2000 was about 7,000; it is now estimated at 12,000. So I think it is, in fact, a town even though the established locals still refer to it as a village. Make of that what you wish; it is irrelevant to today’s walk.
Delving into my 52 Ways to Walk book for this week, I have the snazzy title Breathe as you walk. That sounds fairly obvious. But no, there is more to it than that – let’s focus on Nitric Oxide, NO. (not be confused with nitrogen dioxide, NO2, a brown gas and major air pollutant or Nitrous Oxide, N2O, which is laughing gas) When I studied Biology in the sixties, Nitric oxide was established as highly reactive, having a lifetime of a few seconds, and I don’t recall any properties that applied to the human body. But we are in a different century, and it has assumed some importance to our physiology.
Nitric oxide is a vasodilator discovered in our bodies a mere 30 years ago. One source is from the nasal membranes, so nasal breathing delivers it directly to our lungs, helping to improve oxygen uptake. I have double-checked some of the science, and there is relevant and reliable clinical research. Interestingly, if you hum at the same time, more nitric oxide is produced.
Nasal breathing is already known to filter out more airborne pathogens than mouth breathing, and it also slows breathing, having a relaxing effect well known to Yoga followers.
Hence, on my walk today, I will try to breathe through my nose as much as possible. I realise that most of the time, when exercising, I predominantly breathe through my mouth. A gentle walk around the village/town is chosen. On the flat, slow nasal breathing is easy once you concentrate. Going uphill, breathing in through my nose but breathing out through my mouth works best. I don’t notice any extra energy on this limited walk. Of note, I am much more aware of the traffic fumes when breathing through the nose. Urban walking is probably not the healthiest option when it comes to pollution. On the contrary, at other times the scents of the countryside will be more acute with nasal breathing.
On the whole, during my walk, I find that trying to concentrate on the nasal breathing interrupts my enjoyment of the surroundings and my train of thought. More practice is needed.

I follow one of my usual circuits. Out past the cricket pitch, up Mile Lane (which is only half a mile), and down the path onto the top park. Here I divert to have a look at the little Miyawaki tree plantation. Most are just sticks at this time of year, but I notice yew trees and gorse in amongst them. 

Down Higher Road, I pass the terraced row of stone cottages, said to be the first erected by a mutual building society. 

At the top of the main street is a little fast-food outlet advertising burgers and wraps, not the sort of place I would normally use. But through the grapevine, I learned they prepare a daily curry, cooked on site in small batches from natural ingredients. I have started to pop in when passing to see what’s on offer in the curry department. Everything I have tried so far has been authentic and delicious. I go in today and come away with a portion of black bean dhal and some vegetable pakoras. Rabias Kitchen – my little piece of India in Longridge. As one has to say – other outlets are available. In fact, Longridge is saturated with takeaways. 
I cut back through our recreational park with its children’s playgrounds, skate park, and now the brand-new Pump Track. I stand and stare at some of the youngsters pumping their way around the circuit. It looks like great fun. Let’s try to give our children something to prise them off their screens and possibly keep them away from more antisocial behaviour. Our community is not immune to vandalism and drug problems. 
As an example of antisocial behaviour – I cpme across flytipping by the roadside next to a new estate. 
This is followed by a thorough soaking from a motorist driving over the speed limit through a large puddle. Nose breathing took a dive as I swore at his rapid passing.
I don’t expect to venture far this next couple of weeks, what with the weather and appointments. Local walks will have to do.

Your post certainly resonates with me in a number of ways – local walks mainly on the agenda for me too. Also I’ve been trying to be less of a mouth breather and been actively trying to do more nose breathing with very similar outcomes to you!
One of many local walks in present circumstances.
See Michael’s comment and Sir Hugh’s recommendation.
Thanks for this tour of Longridge, BC. We’ll avert our eyes as we pass the fly-tipping, sadly all too prevalent. That’s really interesting about nitric oxide. I’ve always been onto Qigong – basically all about breathing. Nasal breathing is definitely better, but I could never explain it, at least not in western physiological terms. Until now.
My 52 ways book quotes a good deal of quasi-science. But when I looked further into Nitric Oxide I found the 1998 Nobel Prize in Physiology or Medicine 1998 was awarded to Furchgott, Ignarro and Murad for their discoveries concerning nitric oxide as a signalling molecule in the cardiovascular system.
It remains to be seen how much Nitric Oxide is delivered from the nasal membranes.
Like you I have used slow nasal breathing ( without the walking) for relaxation. There is a lot of science that we don’t understand.
As a fascinating read I much recommend the Penguin: “Breath: by James Nestor -” the new science of a lost art.” which explores in some detail the business of breathing. It was shortlisted by The Royal Society for Science Book Prize 2021 and was a Sunday Times best seller.
Thanks for that.

I should venture to Longridge more. I haven’t been since the lovely cinema closed. What’s that these days?
The cinema is still closed unfortunately.
