Improving Immunity Part 1 - Sleep
Tanner Mackenzie • April 10, 2021
The Benefits of Sleep
Immunity is a complex and multi-faceted area of study. As far back as 430BC, during the plague of Athens, humans were taking note of our bodies’ ability to fight off disease. Immunity continues to be a very active, evolving area of study. There are some things you can do that have been proven time and time again to positively impact your immune system’s performance In this three part blog series, we’ll take a look at three different basic elements of human nature that can impact your immunity.
Are You Getting Optimal Sleep?
Sleep is absolutely critical for optimal human function. When someone comes in to train at Nova Health Club, one of the first things we usually ask is “How did you sleep last night?” Not only does sleep impact your training performance, it also has an effect on your immune system. Getting more than six hours of sleep
reduces your chances
of catching a cold. Logically, this relationship between sleep and immunity should look different for those with greater sleep requirements. If your optimal amount of sleep is eight hours per night, your immune system is likely strongest with this eight hours rather than six.
Correlation between Sleep and Immune System
Recent studies have suggested that a circadian clock drives your immune function. Sleep restriction can disrupt your immune circadian rhythm by interacting with your immune cells. A recent study
created a model
for the relationship between sleep and immunity. The researchers formalized the idea that sleep primes immune cells, and provides a timing signal for the circadian clocks that produce new blood cells. White blood cells, of course, protect the body from infection. If they are not being produced in the right amounts at the right time, our immunity is compromised.
Bollinger et al.
suggest that “sleep disruption desynchronizes these clocks and, through this mechanism, deregulates immune responses.” In other words, if you want your immune system to work properly, get enough sleep!
Your sleep also changes when you are fighting off an infection. Your immune system signals changes to the brain that fragment your non-REM sleep and suppress your REM sleep. Researchers hypothesize that this
brings about fever, improving your recovery from sickness. Whether you are healthy, or sick, your sleep works to optimize your immune function for whatever situation you find yourself in.
Reduce Screen Light
One great way to improve your sleep hygiene, thereby boosting your immune system is to limit blue light into the evenings. This doesn’t mean you have to get off your screen entirely as soon as the sun sets but rather being aware of how late in the day you are going with your eyes fixed on a screen. With many of us working on computers past sundown, you should consider installing
f.lux. It is a free program that allows you to automatically change your computer’s display to warmer colors early in the morning and late at night. Windows and Macs have Night Light and Night Shift respectively, which perform in a similar way, but with less features.
In a world where we are trying to avoid illness especially related to Covid, focusing on sleep is one of the best things you can implement to maintain your health and strengthen your immunity. Let’s get those zzz’s!
Stay tuned for Part 2 of the Improving Immunity series, Diet!

It's that time of year again where Halloween candy is everywhere - especially if you have children who are in the trick or treating age. We all know that candy is unhealthy and we are aware of sugar's detrimental effects on our health, from weight gain to cavities... But do you know the risks in eating Halloween candy that go beyond weight gain and cavities? While sugar is certainly a concern, other ingredients in many popular candies can chip away at your health and well-being. The Deceptive Allure of Halloween Treats While eating Halloween candy can be a nostalgic pleasure, the ingredients list tells a different story. I personally love Halloween but about 7 years ago I went clean and gave up Halloween candy for good because I learned it is much more than a sugar problem… Beyond sugar, are ingredients like hydrogenated oils, high-fructose corn syrup, artificial colors, titanium dioxide and common allergens like wheat, corn, dairy, and soy. These ingredients can wreak havoc on our bodies, leading to a host of negative health effects that most consumers overlook. Beware: 5 Ingredients in Halloween Candy With Negative Health Effects 1. Hydrogenated Oils: Hidden Fats Hydrogenated oils transform liquid oils into solid fats and enhance texture and shelf life. These trans fats are notorious for raising bad cholesterol levels, increasing the risk of heart disease and causing inflammation in the body. Look out for the word ‘Hydrogenated’ in candies like Skittles or Starburst 2. High-Fructose Corn Syrup (HFCS): A Sweet Sabotage HFCS is another frequent offender. It’s a cheap, sweet alternative to sugar that can lead to rapid spikes in blood sugar levels and cravings. Overconsumption of HFCS has been linked to obesity, insulin resistance and fatty liver disease. Many people consume HFCS without even realizing it. Candies like Oh Henry and other chocolate bars have HFCS. 3. Artificial Colors: A Rainbow of Risks The colors that make Halloween candy so visually appealing are often the result of artificial colorings like Red 40, Yellow 5 (Tartrazine), Yellow 6 (Sunset Yellow) and Blue 1. Studies have shown links between these artificial colors and hyperactivity in children, as well as allergic reactions as well. Here are some of your Halloween favorites with these colors: Skittles , Maynards , Sour Patch Kids , Jolly Rancher , Twizzlers , Starburst and M&M’s 4. Titanium Dioxide: The White Truth Titanium dioxide is used in many candies to enhance their whiteness and opacity. It is a detergent that damages your gut and decreases your gut microbiome. Any candy that has a white center, like Skittles is known to use this ingredient. 5. Allergens: Hidden Dangers for Sensitive Individuals Finally, we can’t forget the processed allergens like wheat, corn, dairy and soy in many candies like Mars or Snickers . Those who are highly allergic know to stay away from foods with these ingredients but what about the low grade allergic response that most people ignore? Hives, scratchy through, congestions, asthma, sneezing, itchy eyes and mild GI discomfort are all effects of these allergens. The Scary Reality Halloween is a fun time but we’ve really thrown in the towel when it comes to our health based on the things we are accepting as ok. We've created a society where we buy the cheapest, lowest quality candies to give to our children (and ourselves). Most, if not all of the mainstream candy companies produce products that are high in chemicals to preserve shelf life, to entice our eyeballs and to stimulate our brain to want more the moment it hits our palette. We've also bought into the idea that it's ok because it is just once a year... but the reality is that this food is everywhere all the time. If it was just one day on Oct 31 then sure - that could be ok, but most children are coming home with more than 10lbs of candy that they consume over the next 30 days. It’s no wonder why so many of us suffer with health issues including our children. Modern children are being diagnosed with more health problems than previous generations. Things like childhood depression/anxiety, food allergies, ADHD, autism, eczema and obesity are just some of the things we are seeing more of. Stay Vigilant and Read Labels Can we blame our poor health all on Halloween candy? Certainly not - it's more than just candy in October however the amount of candy with the above ingredients being consumed during Halloween and through the year is definitely a contributor. So when it comes to candy, watch out for the sugar but it’s time to wake up to the other ingredients that are damaging us. The best thing to do is read the labels and be aware of what you choose to consume. And hopefully in time we choose to buy 'treats' that are not filled with chemicals. Next year, choose to buy healthier options versus the mainstream candy we grew up with. Healthier Alternatives Here are some options to consider instead of the mainstream low quality garbage that we've been accustomed too: Chocolate Bars Unreal Coconut Bars : This company is on point with way healthier ingredients than the mainstream. They carry an assortment of candies beyond just the coconut bar (which is one of my faves). Granola Bars Made Good : You've probably seen this brand around in stores - specializing in gluten free healthier granola bars. Cookies Simple Mills : Making cookies and baked goods gluten free and with sweeteners that have a lower glycemic index than regular sugar (less of a blood sugar spike) Candies Smart Sweets : Candies without artificial colors and high sugar Lollipops & Jelly Beans YumEarth : W ithout artificial colors Water Enhancer (Vitamin C) Emergen-C : Something different from usual candy - Vitamin C drink crystals that are a much healthier option to candy and kids love em. There are more brands out there but you have to be on your toes when buying. Pay attention to brands, scrutinize the ingredient list and pay the extra money. Every dollar you spend is a vote - the more we vote for the better products for our health, the lower the cost will end up being in the future.

Having trouble controlling the intake of Halloween candy? Unless you are a disciplined ninja or equipped with helpful restraint tactics, you end up eating too much of this low quality, highly processed junk food. If you are someone with a sweet tooth then you are in luck! Here are 5 tactics that will help you avoid eating too much (if any) candy this Halloween. 1)Don’t Skip Meals or Snacks Skipping meals and snacks creates stress on your body and a stressed body is more likely to have sugar cravings. Self control becomes extremely difficult when you're underfed. If candy appears it is much harder to resist because your body is lacking energy, vitamins and minerals. If you eat a solid meal along with healthy snacks throughout the day (ie: protein shake, apple and almonds) I guarantee that it will be hard to eat candy. 2)Eat Enough Protein On the heels of not skipping meals, make sure each meal has enough protein. Meals that are low in protein mean that they are higher in carbs. As a result you will deal with blood sugar dips and greater hunger, weakening your resistance to candy. How much protein? This differs between people but generally you aim to have at least 0.8 grams of protein per pound of ideal body weight. The more active you are, the more protein you will require. 3)Stay Hydrated Being dehydrated will make you feel hungry even when you are not actually hungry. As a result you are more likely to have the urge to grab a sweet from the candy bowl. The simple solution is to just drink enough water throughout the day. How much water?

By then it’s too late. This may sound strange but as you are picking up the candy - say out loud “I am going to eat this candy” (even if no one is around). This helps you become more aware of your actions, encourages mindfulness, and engages your logical mind. 5)Educate Yourself The scary truth is that mainstream Halloween candy is some of the worst food you can put into your body. Most of these candies contain highly inflammatory ingredients, allergens, and toxins known to disrupt everything from the gut microbiome to DNA, potentially contributing to ADHD symptoms and triggering allergies… And that’s without commenting on the effects of sugar that most of us already are aware of. Eating certain candies can be just as bad as smoking a cigarette! Give these tactics a try - they should help you to say no to Halloween junk food this year. If you are still having trouble, you can attempt a ‘clean sweep’ by throwing it all into the garbage… If you still have a sweet craving, have some dark chocolate or walk to the best bakery in town and buy yourself a $10 chocolate croissant :) Happy (Healthy) Halloween!
