Lungs are amazing. There they sit, inflating and deflating from dawn to dusk, dusk to dawn, sucking successful air, stripping retired oxygen and exchanging it for c dioxide. They bash this 20,000 times a day, 7.5m times a year, 600m times successful the mean lifetime, keeping our trillions of cells ticking implicit and redeeming them from choking connected their ain exhaust fumes. And we disregard them until thing goes incorrect and we’re gasping, wheezing, panicking – oregon worse.
When I deliberation astir lungs, it’s often successful the aforesaid enactment arsenic cancer, which killed my dada 39 years ago. He lone realised his lungs were knackered aft a bosom attack, which was astir apt besides down to smoking. Sixty Senior Service a day, cigaret fig 2 often lit arsenic soon arsenic fig 1 was stubbed out. He stopped overnight, but it was excessively late.
I’ve ne'er smoked, truthful I don’t interest overmuch astir lung cancer, and I don’t person asthma, oregon a persistent cough, oregon shortness of breath. But I inactive privation to cognize however beardown my lungs are. I’m 61, aft all, and lung relation begins to decline successful your mid-30s. And it’s astir a twelvemonth since I gave excavation a due workout, acknowledgment to a genu injury. From moving 30km oregon much a week, with a hard sprint to decorativeness astir sessions, I’m down to zero. In all, I’ve missed much than 100 hours of aerobic exercise.
But my genu is connected the mend, aft keyhole country to trim a torn meniscus, and contiguous I’m going to propulsion myself to the bounds again. In a greeting of tests astatine Sheffield Hallam University’s Advanced Wellbeing Research Centre, we’ve already measured my lungs’ capableness and wide efficiency. That was a elemental process called spirometry, which mostly comes down to blowing into a tube. Now I’m astir to get connected an workout motorcycle and pedal until I’m excessively retired of enactment to continue. I’ll person a disguise strapped to my face, a bosom complaint show connected my chest, idiosyncratic to drawback maine if I faint and a bucket to manus successful lawsuit I propulsion up.
“You’ll find it beauteous unpleasant,” says Alex Bugg earlier picking up an tremendous syringe. He’s a researcher astatine the university’s schoolhouse of athletics and carnal activity. Before I person clip to panic, Bugg explains that he’s lone going to usage the syringe to calibrate the equipment.
If you privation to cognize however good your lungs (and heart) enactment nether stress, this VO2 max trial is the champion mode to bash it. The disguise volition measurement the gases I’m breathing out, and hence however overmuch oxygen my assemblage tin usage erstwhile moving level out. You tin get an estimation for VO2 max from a smartwatch oregon different fittingness tracker – but for implicit accuracy you’ll request to bash what I’m doing, oregon get masked up and tally connected a treadmill. If you instrumentality that option, you’ll usually beryllium strapped into a harness, successful lawsuit your legs springiness way.
I commencement disconnected conscionable spinning my legs against a flimsy resistance. Bugg tells maine to find a comfy cadence that I tin support for arsenic agelong arsenic imaginable portion helium gradually increases the drag, from 50 watts to conscionable implicit 300. So I pootle on astatine astir 75 revolutions per minute, which feels similar the benignant of gait I’d clasp if I was cycling unhurriedly connected the flat. I don’t cognize my watts from my wazoo, but basal maths suggests that by the extremity of the trial I’ll person to enactment successful six times arsenic overmuch effort. Meanwhile, Bugg and a workfellow volition support checking however I’m doing, holding up a illustration wherever I tin prime retired my perceived complaint of exertion.
“Six is implicit rest,” helium says, “while 20 would beryllium an all-out sprint with thing near to give. Towards the end, erstwhile you commencement to get a spot much breathless, consciousness escaped to constituent alternatively than speak.” He, successful turn, volition support asking: “Happy to continue?” All I’ll person to bash is nod, springiness a thumbs up oregon shingle my head.
Let’s conscionable get connected with it, I think. Then, erstwhile we do, I privation we hadn’t. As the absorption increases, we’re soon successful “somewhat hard” territory, past “hard”, “very hard”, “extremely hard”. My quads commencement burning and I power to breathing done my rima alternatively than my chemoreceptor – astatine archetypal silently, past successful unhappy, ragged gasps. “We’re astir apt getting precise adjacent to your maximum now,” Bugg tells maine 13 oregon 14 minutes in, arsenic if I hadn’t already realised. When we deed it, astatine 253 watts, I fto everyone know, not by saying truthful oregon pointing, but conscionable … stopping. I don’t person immoderate choice: nevertheless overmuch I gasp for air, I can’t support pushing. I’m done.
At slightest I didn’t faint oregon vomit. I adjacent get disconnected the motorcycle without assistance.
We’ll get to the results successful a minute, but if I wasn’t successful this state-of-the-art lab, however would I cognize if I needed to interest astir my lungs?
“If you tin locomotion a mates of blocks oregon up 2 flights of stairs without getting breathless, you tin workout without getting fatigued easily, you bash not kick of thorax pain, cough oregon bring up sputum each day, you bash not person humor successful your phlegm, oregon wheeze, your lungs are astir apt each right,” says Dr Pallavi Periwal, an Indian pulmonologist and captious attraction physician, and the writer of Make Every Breath Count. “Also look for signs similar swelling of your feet, oregon curling-up of your nails, called clubbing. If immoderate 1 of these oregon a operation of these symptoms are present, get yourself checked out.”
Don’t presume you’re successful the wide conscionable due to the fact that you don’t smoke, she adds. “Yes, of people smoking’s a large hazard origin arsenic acold arsenic lungs go. But truthful is vaping and utilizing a hookah, and secondhand smoke. Even if you bash not fume yourself, you could beryllium a passive breather of mediocre air.”
Then there’s aerial pollution, indoors and out. “Check the air prime index earlier you spell out, particularly if you unrecorded successful a metropolis that is highly polluted,” Periwal says. Use a look disguise if necessary, and debar exercising outdoors erstwhile the aerial prime is poor.
“If you can,” Asthma + Lung UK advises, “avoid contamination hotspots similar main roads, junctions, autobus stations and car parks. Try to usage quieter backmost streets arsenic overmuch arsenic imaginable oregon spell retired earlier earlier contamination levels increase.”
“Indoor aerial contamination is besides thing radical bash not deliberation about,” Periwal says. “Things similar mould, household chemicals, country fresheners, radon, burning candles and incense sticks tin each impact indoor aerial quality. Ventilate your location frequently, particulate and vacuum regularly, debar chemicals with volatile integrated compounds successful your house, support it smoke-free.”
Pets tin origin problems too. Many of america are allergic to canine oregon feline fur without realising it, portion vertebrate droppings oregon feathers tin bring connected a information called hypersensitivity pneumonitis.
In her ain home, Periwal says, “I bash not smoke, vape oregon let immoderate indoor fume – nary incense sticks oregon candles for me. I regularly particulate and vacuum and ventilate my house. All furniture linen, sheets, pillows are cleaned regularly. Kids’ brushed toys are washed and dried regularly. These are large allergy triggers.”
At the hazard of stating the evident – but hey, it’s 2025 and there’s an anti-vaxxer moving 1 of the world’s biggest healthcare systems – it’s besides important to get vaccinated against communal respiratory infections specified arsenic flu, particularly if you autumn into a high-risk group.
And what are the options if you request to fortify your lungs?
“Exercising helps,” Periwal says. “Aerobic exercises similar running, jogging and brisk walking amended your carnal fittingness and your assemblage becomes much businesslike successful getting oxygen and transporting it to your muscles. Strength grooming builds halfway strength, improves posture and tones breathing muscles.”
These muscles substance due to the fact that your lungs don’t inflate and deflate by themselves immoderate much than a balloon does. That’s the enactment of your intercostal muscles (the ones betwixt the ribs) and your diaphragm, the dome-shaped expanse of musculus that stretches beneath your chest. Strengthen these, and you fortify your breathing. For patients with chronic lung problems, Periwal besides recommends breathing exercises, peculiarly diaphragmatic breathing, sometimes known arsenic abdominal oregon belly breathing, and pursed articulator breathing, successful which you inhale dilatory done your chemoreceptor and exhale mildly done your – conjecture what? – pursed lips.
Doctors volition sometimes prescribe inspiratory musculus training (IMT), AKA respiratory oregon ventilatory musculus training. I’ve been experimenting with a Powerbreathe trainer, disposable connected the NHS if you person lung problems but besides marketed to athletes wanting to amended performance. Twice a day, I instrumentality 30 short, crisp breaths, moving against an adjustable resistance.
It feels arsenic if I’m utilizing the aforesaid muscles that I would astatine the extremity of a truly hard workout, erstwhile I’m trying to suck successful arsenic overmuch aerial arsenic possible, arsenic profoundly arsenic possible. “It’s a heavy diaphragmatic belly breath,” says Dr Sabrina Brar, a erstwhile ear, chemoreceptor and pharynx surgeon who is present a aesculapian serviceman astatine Powerbreathe. “Some radical get a sore tummy.”
Brar describes IMT arsenic dumbbells for the lungs. It tin beryllium utile “if you are grooming to beryllium an jock oregon endure from a lung condition”, Periwal agrees, “but larn the due method with a respiratory therapist. Do not overdo it.”
Anyway, my results. They’re not atrocious for an aged antheral whose occupation is mostly arse-on-chair. “A steadfast 60-year-old antheral tin expect a VO2 highest of 25-45ml/kg/min,” Bugg’s study reads. In different words, that steadfast 60-year-old volition devour 25-45 millilitres of oxygen per kilo of assemblage value per minute. A fig supra 35ml/kg/min, meanwhile, suggests “a precise bully level of fitness”. Not bully capable to gain you the maillot jaune, however: “Current Tour de France champion Tadej Pogačar has been reported to person a VO2 max astir 89.4ml/min/kg, meaning his assemblage tin usage much than treble the magnitude of oxygen during workout compared with the mean man.”
And me? My figure’s 41ml/kg/min. “Your VO2 max is supra average,” the study says, “and suggests a precocious level of fitness, and precise businesslike bosom and lungs. Not lone are your lungs successful bully health, but your assemblage is good adapted to utilise the oxygen you respire successful and to dispose of the c dioxide discarded merchandise that accumulates during exercise.”
There’s a thumbs up from the spirometer too. “Overall, you person fantabulous lung function. You person above-average lung capacity, ratio and power. There are nary concerns that your lungs are obstructed oregon impaired successful immoderate way, and they tin inhale and exhale arsenic required.”
I’m tempted to preen until I retrieve Pogačar’s stats, and that Bryan Johnson, the 47-year-old squillionaire spending $2m a twelvemonth truthful helium tin unrecorded for ever, claims helium recorded a VO2 max of 64.29. That, helium says, is adjacent to “the apical 1% of 18-year-olds”.
As for Bugg, 33, it’s 8 years since helium measured his VO2 max, but backmost past it was an awesome 55. He’s presently grooming for a stair marathon. There are 5 floors successful the Advanced Wellbeing Research Centre, and connected 24 July helium volition beryllium walking up and down them 227 times successful assistance of the Motor Neurone Disease Association. However bully I consciousness astir my lungs now, I don’t deliberation I’ll beryllium joining him.
