To milk a bull

by Brandon Mayer

Allow me to be among the first to extend a warm welcome for the summer season. Yes, a “warm” welcome. Pun intended. Summer is a very hot and often humid season. This is not new – Eastern Ontario summers have been hot since anyone alive today can remember – but our understanding of how the heat can impact our minds and bodies is ever-evolving.

All living things on Earth adapt and evolve to their environment over a very long period of time. That’s what gives our bodies their amazing “built in” features that keep us alive. One of our coolest features (another pun intended) is our ability to sweat to cool down. Sweating to cool down is a multi-step process. When we sweat, body heat is transferred to the sweat when it leaves our body. This is why a fan blowing air feels extra cool when you’re sweaty or otherwise wet – the sweat is taking body heat with it as it blows away or evaporates.

Despite its simplicity and usual effectiveness, there are two reasons why sweating is not always the best “human cooling system”. One is that it only works when the warm sweat can leave our body. Air can only hold so much water just like coffee can only hold so much sugar. When air is 100% saturated (what we call “100% humidity”), the air will not absorb any more evaporated water or sweat (no matter how hard it tries!). The result is that sweat gets stuck on our bodies and instead of cooling us off, it feels like a warm bath of horribleness. This is why the higher the humidity goes, the higher the temperature feels even if the temperature is not actually rising.

The other inadequacy of sweating is that kids don’t have the ability to sweat quite as much as adults, despite the fact that children’s bodies produce heat faster than adult bodies. In other words, sweating is far less useful to kids than it is to adults. This is why heat warnings from popular weather services warn that young children should take extra precautions. It’s also noteworthy that adult caregivers may not feel as warm as kids, and may therefore not take kids seriously when they complain about the heat.

Letters to the Editor

Dear Editor,

A message for John of Baldwin’s Birds:

Thank you so much for your always delightful and interesting bird observations. We, like you, consider the birds and other creatures in our yard to be part of the family.

Your story of the wren that collided with your glass door reminded me of something I learned from an acquaintance — that often the bird may seem to be recovered from the collision but, being a delicate creature, may suffer internal bleeding. The only way to ascertain this is to pick the bird up (and I agree this causes them more stress) and blow lightly on their tummy feathers. If you see bright red, they are in trouble and need to be rushed

To bring this semi-scientific discussion to a sociological conclusion, I ask a simple question: why, in 2023, do schools not have air conditioning? Global temperatures are rising by an average of 0.18 degrees Celsius per decade. This may not seem like a lot, but consider that in an 80 year lifetime, the average daily temperature will rise by almost 1.5 degrees Celsius. This is at current warming rates, but warming rates themselves have more than doubled in the last few decades. A degree-and-a-half? What’s the hype? The hype is that what may not seem like a big deal becomes one when it is compounded decade after decade, and our bodies have no chance of adapting to these new conditions this fast.

Regarding air conditioning in schools, I expect the usual answers. “School is not in session in July and August.” “It’s a waste of taxpayer dollars.” “Kids are resilient.” Oh please! Some of the days this past April were getting uncomfortably hot. When my wife and I got married in mid-May of 2022, it was over 30 degrees Celsius and humid.

We had picked May partially to avoid the heat! And we all know that September and October can get very hot. Working in the school system, I can confirm that my shorts come out early May and often stick around until at least early October. School buildings are very hot, and spending money on kids is much less a waste than other government spending.

Let’s not forget about the fact that school buildings – particularly elementary school buildings – are used in the summer. Camps and other forms of childcare run. Community groups can “borrow” the space. And there is a lot of grunt work happening by custodial and administration staff, including the moving of furniture and waxing of floors.

I ask again – WHY, particularly considering that technicians have already visited most schools recently to install ventilation upgrades, have we not considered air conditioning for schools? Every other government building has them, as do most stores (even small ones) and most homes.

Here’s the part that really annoys me: doesn’t it make sense to assume that kids who are overheated and feeling sticky and uncomfortable are bound to learn less effectively? It turns out that we don’t have to assume. When I researched the impacts of excessive heat on student learning, the evidence was very clear – the impacts are huge. Students do worse on tests in heat waves, and their cognitive function is reduced. One study even found that a 1 degree hotter school year causes a 1% drop in student learning for the year. That 1.5 degree global warming doesn’t seem so insignificant now, does it? Students learn incredible foundational knowledge at school. Learning even 1% less of it can affect society perhaps more than we will ever know until it’s too late.

Is it time for schools to get air conditioning? I’ll answer with an analogy. Just as a classic novel teaches us that racism is just as pointless and baseless as it would be “to kill a mockingbird”, I argue that expecting effective learning to be happening in sweltering hot schools is like asking educators “to milk a bull”. Trying to get attention and focus out of uncomfortable students is unfair to both educators and students. School is designed to train and develop young minds and bodies, and if these young minds are uncomfortable at best, and impaired at worst, we are setting ourselves up for failure. I don’t have answers for global warming, but I do know that we need to take responsibility for making sure that kids can learn effectively and beat the heat. to the Wild Bird Sanctuary on Moodie Drive in Ottawa. Many door and window collisions, fortunately, are mild, more like glancing blows and guarding the bird at a distance as you did gives it time to recover its senses and fly off and continue with its day.

My husband and I discovered a wonderful product call "UV Liquid” made by WindowAlert. This product looks like a Bingo marker and one smears it in a zigzag pattern over one's windows and glass doors. While it dries clear to us, it is bright neon purple to birds' eyes so they are not fooled into thinking they can fly through it. We have had no bird impacts since we have applied this product to our windows.

It is available online at www.windowalert.com or at the Wild Bird Centre on Bank Street in Ottawa.

I hope you find that helpful, All the best Janice Atkey

Response from John Baldwin:

Dear Janice,

Thank you very much for your complementary and very informative response to my article, regarding my own Wren window-strike. I shall definitely have to obtain some of the UV spray that you informed me of when I am next in Ottawa near The Wild Bird Centre since I cannot get it online due to the shipping restrictions on such materials, per the WindowAlert website. (UV Liquid orders ship FedEx Ground to continental

U.S. destinations only. FedEx does not deliver to post office boxes. UV Liquid cannot be shipped to Alaska, Hawaii, or international destinations including Canada.).

I found the Wild Birds Unlimited site very informative, especially their "Birding Links", which gives details of the Ottawa Valley Wild Bird Care Centre which is available every day of the year for the reception of injured or orphaned birds. I shall endeavour to include this fact in my next article.

Thank you once again. Stay safe and well, Cheers,

John

Dear Editor,

I was pleased to see the beautification project undertaken by the staff at the Oxford Mills waste transfer station. They artfully arranged several discarded bathtubs and created a lovely flower bed, complete with waterfall. Without studies, meetings or reports, they took the initiative during their breaks and improved their work environment and our experience. Thank you and keep up the good work.
