Can I increase my vitamin D intake with eggs?

The other day, I went down a rabbit hole trying to find out if there were any differences between brown and white eggs. They are laid by different types of chickens and traditionally the hens that laid brown eggs were bigger and therefore cost more to feed, hence the price difference that got passed to … Continue reading

Will a Face Mask Help With my Allergies?

This never would have even occurred to me to ask if it hadn’t been for the covid-19 pandemic, but since wearing face masks is a thing in North America now is there any chance they will improve my allergies? Dror et al (2020) found that nurses with chronic rhinitis including runny or plugged nose, sneezing, … Continue reading

Should I be having spinach in my smoothie?

I get spinach to use in salads, but I don’t often use enough to use it all up. In an attempt to reduce food waste I started adding the spinach to my smoothie in the morning. But then I fell down the internet rabbit hole of health advice. The number of different messages about raw … Continue reading

Is simulated nature the same?

I’ve written before about the physical and psychological benefits of seeing and spending time in nature. Similarly, I’ve written about some of the barriers that people face in accessing natural settings. Which leads to the question of whether simulated nature has the same benefits as the real thing. Browning et al (2020) asked this question … Continue reading

Reparations and Community Health

It is well documented that Black and other marginalized communities have been disproportionately affected by COVID-19. Rates of infection, hospitalization, and death are all higher for individuals who are Black compared to white. A new study led by Harvard Medical School examined how monetary reparations to the descendants of Africans enslaved in the US could … Continue reading

The role of climate change in the current pandemic

Most of the discussion around climate change and the current pandemic focuses on how actions to combat climate change have been set back by the battle against the covid-19 pandemic or perhaps the opportunity to integrate climate policy into the global and local recovery plans. But research by Beyer, Manica, and Mora (2021) indicates that … Continue reading

Wandering Brains

When I was a camp leader we used to joke that the secret to being a good leader was having a shorter attention span than the kids in the camp. I use a variation of this same philosophy in my teaching. I try to use a variety of different approaches to teaching and learning, and … Continue reading

All about puppies

I have an 8 week old puppy in the house and he’s making writing my blog post this week a little more challenging, so I thought I may as well use him for inspiration. I’ve noticed that if he can see the training food pieces he doesn’t really care that I have one in my … Continue reading

Birds that change colours AND wear snowshoes

I find ptarmigan quite fascinating. They live in alpine and tundra areas. These areas are not typically bird habitat, but ptarmigan like grouse primarily live on the ground. They walk around foraging for plants and occasional insects. They will live in these barren areas all year round, so it isn’t surprising that they are well … Continue reading

What kind of workout is cross country skiing?

On the surface, cross country skiing seems akin to something like running. You primarily work at a steady pace with occassional extra effort on a climb or a brief moment of respite downhill. However, competitive cross country skiers in both sprint and distance events have a much more variable output. In most races, the terrain … Continue reading
