Do You Know How Much Urine is in the Swimming Pools?
By MORE Team

The weather is getting hotter and hotter, what beats escaping the summer heat with a refreshing splash in the pool?

But have you ever thought of a question: How much urine is there in the pool?

Let’s talk about that today.

Blogger Mark Rober spoke with a couple of scientists to find out the average amount of pee in a swimming pool. The giveaway is the amount of artificial sweetener in pool water. And the unmistakable pool smell.

Mark sampled private pools and public pools four times and sent the samples directly to a laboratory for inspection

Mark visited Lindsay Blackstock, a PhD student of analytical and environmental toxicology at Alberta University to learn about her ingenious method for measuring the amount of pee in a pool by looking at the concentration of an artificial sweetener called Acefulfame Potassium, it’s commonly found in processed foods and fizzy drinks. This is commonly found in urine because it passes straight through the body undigested.

They looked at samples from some pools in his area to determine how much pee was in them and he conducted an experiment of his own to see what was the cause of that "classic pool smell". He also presented average amounts of pee in large pools as well as an equation to determine how much pee is in your own pool.

In fact, you can also get the results by measuring the amount of urea in the pool, but urea can also come from human sweat, and sweat is very common in pools, so you cannot tell how much urea actually came from pee.

Before the results of the experiment came out, Mark learned a big "secret"!

It took about an hour for the mass spectrometer to detect the results. When Mark waited, Lindsay also told him an amazing fact...

Adding chlorine into a pool can disinfect the water because it kills harmful bacteria, viruses and microorganisms...

However, there is also a big disadvantage! Chlorine for disinfection reacts with urea in the pool to form trichloroamine, that’s why you may smell it when you enter the indoor pool. It is actually the smell of trichloramine, which is the   of urine and chlorine, not just the smell of disinfectant water.

To prove this, Mark personally tested it. He prepared two 5 gallon buckets, and filled them with pure water, then added four times the recommended concentration of chlorine for that volume of water to both buckets, and then added a little urine to the bucket B.

After 3 days of waiting, it’s time for the truth.

Bucket A still smells like water even with four times the recommended chlorine concentration, while bucket B smells like a swimming pool. The only difference is that bucket B has a small amount of pee in it. The smell reminds us of summer vacations in a 5-star hotel’s pools or water parks. It turns out… it’s just pee.

The classic pool smell doesn’t sound like a big deal, but the problem is it’s kinda bad news for both your lungs and your eyes.

If your eyes are really red after swimming for a while, that’s because of the trichloroamine from the pee, not the chlorine. Trichloroamine also causes asthma, in fact, studies show that asthma is more likely to occur among lead swimmers than any other high-level athletes, which now make sense, because Michael Phelps admitted to always peeing in the pool and he says everyone does it too.

In Lindsay’s research, she sampled 20 public swimming pools and 10 public hot tubs. The average concentration of sweetener for the public pool was 470ng/L , and 2247ng/L for the public hot tubs.

So what about Mark’s samples? The concentration of artificial sweetener in his friend’s backyard pool is 69ng/L. Although it is much lower than the average, it equals just under a gallon of pee. Mark's hot tub has a slightly higher concentration of artificial sweetener at 103ng/L.

In another set of samples taken by Mark in a public pool and hot tub, the concentration of artificial sweetener is 27ng/L for the pool and 335ng/L for the hot tub, respectively.

Those numbers are much lower than the average levels of the 30 samples that Lindsay collected, which leads Mark to believe that the water has been completely replaced recently.

If you want to estimate the pee in your pool, Mark came up with a simple equation after talking to some professionals and the equation depends on the number of people.

Average:
numbers of swimmers × 1.2 = gallons of pee

If you think they pee more than average: 
numbers of swimmers × 2 = gallons of pee

If they are more disciplined:
numbers of swimmers × 0.5 = gallons of pee

An Olympic pool would contain over 130 gallons of pee.

While some people swear by the health benefits of drinking urine, which is sterile, taking a gulp of the stuff in a swimming pool is not a good idea.

Urine contains many nitrogenous compounds such as urea, ammonia, amino acids, and creatinine. These compounds can react with disinfectants (e.g., chlorine) in swimming pools to form disinfection byproducts (DBPs).

Although considered a taboo, 19 percent of adults have admitted to having urinated in swimming pools at least once.

So be cool, don’t pee in the pool!

Caring for Your Skin During the Winter Season

Your skin is the largest organ that you have in your body and it is one that has multiple uses. It not only covers and protects everything inside your body, but it also helps your body stay at just the right temperature and allows you to have the sense of touch. Your skin, however, is often the one organ that we do not look after-especially during this time of year.

The winter and spring are particularly vulnerable seasons for your skin. The winter in particular can play a huge role in the way your skin reacts. This is especially the case in the northern parts of China where the weather is harsh, cold, dry, and dusty. People with sensitive or dry skin are particularly prone to problems during the winter season.

A common condition during the winter season and one that we treat often is dry, itchy skin. If you are suffering from this condition it is often easily treated, but remember to see your dermatologist or doctor straight away to be properly diagnosed.

By following the tips below, you will be able to beat dry itchy skin before it even starts this winter.

Tips to help you get your skin through the winter season

Do not take more than one shower/bath a day
Over washing removes the natural lubricant that skin produces and makes skin dry and flaky.

Do not shower/bathe for more than 10 minutes
The longer you stay in the water, the drier your skin will get.

Do not shower/bathe in hot water
Heat increases the rate that water evaporates from your skin leaving it dry. Luke warm water is a better choice.

Avoid saunas and steam baths
Like hot showers, they increase the rate that water evaporates from your skin leaving it dry.

Use a mild formula soap or shower gel and don't exfoliate

Apply moisturizing cream right after you shower/bathe while your skin is still damp

Moisturizers lock water into your skin but do not help add water so the best time to apply them is straight after your body has been in contact with water. For very dry weather, a thin moisturizer that is applied after a shower is not enough; in this circumstance, some thicker and greasier creams will do a better job.

Avoid wearing nylon or woolen clothing because these materials can irritate your skin
Loose fitting undergarments made out of 100% cotton are best when your skin is dry.

Air-conditioners, over-heated rooms, and windy weather all make the environment dry, which in turn can make your skin dry
To combat this, put some plants, fish-tanks, or humidifiers in your office and home.

Apply some extra protection if you have to go out on a windy day

The sun is not as hot or bright in winter

however, if you are outdoors for long periods of time, your skin can still get sunburned, particularly in the snow
Be sure to apply sunscreen in these cases.

Avoid spicy food as it can make your skin dry and itchy

Drink lots of water and limit your intake of alcohol

Wellington College International Hangzhou is pleased to announce the opening of admissions for their first ever cohort of Year 10 students to take the IGCSEs in the 2020-2021 academic year.

What are the IGCSEs?

IGCSE stands for International General Certificate of Secondary Education, which is a globally recognised qualification taken in Years 10 and 11 (Grades 9 and 10) and carries the same weight as the GCSEs that are offered within the UK. The IGCSE is one of the most sought after and recognised qualifications in the world, because it helps students develop core skills and competencies, including investigative skills, problem solving, teamwork and critical thinking. These skills are highly sought after by universities around the world, and as such, students who have completed the IGCSEs are generally regarded as highly competent candidates to enter such universities.

IGCSEs are also the most popular international qualification in schools around the world, with more than 4,800 schools over 150 countries doing the Cambridge International Examinations version of the IGCSE alone. Enrolling your child in the IGCSE programme at Wellington will provide them with a vital boost to their academic career, which will not only help them build on their study skills, but will make them more competitive and prepared to enter their senior school programme, whether that is offering A Levels or the IB Diploma Programme.

For the 2020-2021 academic year, Wellington College International Hangzhou is accepting an extremely limited number of applicants into Year 10 and is seeking students who will be able to achieve the world-standard results expected of them at Wellington.

In reflection of the importance of this first cohort, Wellington College International Hangzhou is proud to announce a range of scholarships, including an academic scholarship for Year 10 that includes significant reductions in tuition fees for the duration of the two-year IGCSE programme, with the option for this to be extended throughout the two-year A Level programme, subject to a favourable academic assessment.

This is an exciting opportunity for talented students in Hangzhou to receive a significant tuition reduction, allowing access to the world-class holistic education which Wellington has to offer.

As well as meeting the admissions requirements for Wellington College International Hangzhou, and being able to demonstrate significant academic potential as determined through the admissions assessment process, other traits that Wellington College International Hangzhou seeking from their Wellingtonian pupils include;

An international outlook and a desire to be a global citizen of the future

A willingness to work hard with a positive attitude towards learning

A desire to develop all Wellington Identities, to take full advantage of the opportunities on offer at Wellington and show a commitment to making a positive contribution to the wider Wellington community

An aspiration to live by the Wellington Values

To learn more about the IGCSEs and the academic scholarship programme, we encourage prospective parents to join Wellington for their IGCSE Parent Information Sessions being held on Tuesday, December 3rd and Tuesday December 17th.

Do You Rumble?

Don’t have motivation to go workout? Tired of running alone? Bored of lifting all those weights in the gym? And got too many injuries from CrossFit? Here comes boxing to shake up your work-out routine!

Benefits of Boxing

Boxing is a truly fantastic sport and it isn’t just for those giant beasts of men that you see on television. Boxing is a sport that everybody can participate in and that makes a huge difference. Of course, you don’t actually have to step in the ring in the form of competitive boxing. We realize that not everybody wants to fight other people for fun, not to mention that taking a few shots to the noggin can definitely hurt your brain, but you can always box for fun and you can definitely engage in all of the training that comes with it.

There's a reason why boxing is the workout of choice for so many celebs and models. Not only is fighting a strength and cardio workout in one, it's the best way to get in tune with your inner badass.

The boxing workout is great for fat loss. Almost every boxing exercise will make you sweat. No matter if you're doing heavy bag work, mitt work, jumping rope, sparring, push-ups or even shadowboxing, you're going to burn calories. You can lose 3-4 pounds in a single workout if it's intense enough. The main physical benefit beginner boxers will see is cardiovascular since boxing improves your resting heart rate and muscular endurance. That lowered resting heart rate and increased stamina can give you an edge in your other workouts.

With a potential burn rate of 13 calories a minute, boxing goes head-to-head with other types of cardio like running and cycling. Plan to punch away anywhere from 200 to 400 calories (for a 140-pound individual) per half hour. Thirty minutes of boxing in a ring torches 400 calories; 30 minutes of punching a bag vaporizes 200 calories.

And now we’re getting to the point, Do You Rumble?

What Is Rumble Boxing? 


Rumble is HIIT (High Intensity Interval Training), strength training, metabolic conditioning (METCON), and uppercut throwing cardio all combined in one clean class.

Rumble was founded by entrepreneur Andy Stenzler, who co-founded Cosi and Kidville; Eugene Remm, a nightclub guru, restaurateur and Rumble’s chief brand officer; Noah Neiman, former Barry’s Bootcamp master trainer and a Bravo “Work Out New York” star; and Anthony DiMarco, an 11-time Ironman competitor and former managing director at Google. It’s been said that Rumble is the ‘next big thing’ and that they are uniquely positioned to help shepherd and expedite its growth.

Rumble’s workouts are built around a 45-minute full-body strength-training and conditioning class that features teardrop-shaped, water-filled punching bags (designed not to hurt wrists or other joints), and moves to floor workouts with weights before going back to the punching bags — with inspiring hip-hop and house music mixed with “classics” from Biggie Smalls to the Fugees.

We Tried It: The Rumble Boxing Workout Kendall Jenner, David Beckham and Selena Gomez Love

This class is a challenge from start to finish! We were dripping in sweat and our muscles were on fire, but the beauty of it is that you can go at your own pace. And NO prior boxing experience needed!

Once you check in and get your glossy custom white gloves and wraps, you head inside the dimly lit room to warm up and start throwing punches. Coach Shield, who studied in US and speaks fluent English, will guide you through every step.

We love the darkness for two reasons: 1. You get in there and get in the zone. No one cares about what the person next to them is doing, even if it’s Selena Gomez… it’s all about putting in the work without having to think about what you look like. 2. The lighting system is timed perfectly with the music so you feel like you’re dancing at LIV Miami. When that red light hits you, it’s hard not to turn it up.

And then, of course, there’s the reputation of Rumble Boxing itself. It’s known for attracting celebrities (Kendall Jenner, Hailey Bieber, David Beckham, and — based on Rumble’s Instagram — an absurd number of models) in New York and Los Angeles. Now, we’re getting a taste of that celebrity-endorsed life with our own Rumble Boxing Hardcore Man Boxing studio in Hangzhou.

We swung by for a class on opening day to see if it would live up to the hype, and it didn’t disappoint. Hardcore Man Boxing is located on the 3rd floor of Gemini Mansion in Binjiang. Once you arrive, you’ll see the night club styled studio in black and red.

The studio itself is outfitted with intense sound systems, screens, and lighting (we’re talking black lights, which add some serious dramatic effects) that make the workout experience fully immersive. The water-filled punching bags are from AQUABAG, it costs 3,000RMB each, and there are 37 of them.

There is also a dedicated heart rate meter to record the calories that you’ve burned. The calories burned per lesson will be uploaded directly to the big screen so you can see how much fat you’ve lost in one class.

The locker rooms — slick, pristine white spaces — have all the amenities you’ll need to freshen up after class, including shower gel, shampoo, cotton pads, and even Dyson hairdryers.

After the class, you can enjoy a healthy meal at the reception that has less than 300 calories and costs 30RMB.

We were promised a high-end boutique studio, and that’s exactly what we got.

As for the workout itself, it’s honestly the most beginner-friendly of all the new boxing workouts. The class is 45 mins and the courses are divided into different training intensities (low, medium, and high), from warming up, to weights, to boxing training. The whole studio is filled with hanging aqua bags. Rumble’s teardrop-shaped, water-filled punching bags AQUABAG takes the place of traditional heavy bags.

Overall, the class is a high-energy, upbeat, music-fueled, sweaty good time. (Oh, and you will be sore. Three days later and our abs are still feeling it.)

After experiencing Rumble myself, now I know why the members and trainers look as great as they do. It was an amazing workout with entertaining trainers and an all around awesome time. Rumble: Celebrity tested, MORE Hangzhou Approved.

Now MORE Hangzhou has the opportunity to invite you all to come to have a drop-in at 3pm on Sunday, Nov. 17th for only 68RMB (cost 298RMB on sale), it’s definitely on the higher end of the range for a workout class, but hey, it’s boutique fitness — we never said it would be cheap. Ready to punch and kick?

Pre-sale price: 68RMB
(the registration closes at 5pm on Friday, Nov.15th)
Ticket-at-the-door: 88RMB
