How Cycling Boosts Your Immune System


Ever notice the pulse in your blood, the increase in energy, and all around vitality that seems to follow a ride? Granted, most of that is adrenaline. But some additional theories have been hypothesized about a link between exercising and an incredible elevation of the bodies immune system. Though none of these theories have been proven, they do align with the general patterns our bodies operate under for optimum health.

Flushing Out the Lungs
Low impact, aerobic movement often give people a quicker heart rate and leaves them out of breathe. Believe it or not, there have been those who claim that the deep panting may aid in the clean out of bacteria in your air ways and lungs. By doing so, your body is lowering your risk of viral and sinus infections. There has to be some truth to it since deep breathing techniques in yoga and other relaxation routines have been proven to do something similar.
Circulation of White Blood Cells
The police and hospital of your blood, the white blood cells in our immune system, seem to work sluggishly in people who don’t exercise, and in high gear in those who are regularly active. So not only does cycling help get rid of bacteria in your airways, but also in your life liquid. Similarly to adrenaline, the boost to your immunities is temporary, lasting less than three hours. However, that time frame is plenty to keep illness at bay. A person who works out their muscles daily is more likely to stay healthy than someone who does not.


Slows Stress
Another level of healthfulness cycling and other exercise can give your immune system is in the production of neuro-hormones to improved cognitive function, elevated mood, and learning. In a nutshell, it drops stress, pedals you plum out of depression, and cranks up creativity and mood. Strangely enough, despite this physiological system improvement, our stress hormone cortisone actually temporarily raises during intense exercise. But the quick fall upon workout completion is what seems to fire up all the advantages our bodies get from any given ride.
A Word of Caution

All this great information doesn’t mean to go hog wild with your rides. Never push yourself too far or beyond realistic limits. Over working your body can and will erode away all the advantages above, dropping your immune system into hibernation and rendering you ill.
For maximum immunities, continue your ride habits or challenge yourself slightly. As Edward Stanley, the Earl of Derby once said, “Those who think they have not time for
bodily exercise bicycling will sooner or later have to find time for illness.” (Slightly modified.) So to avoid bodily plaques, keep on riding!

7 Foods for Your Immune System to Help Ward Off Illness

It takes more than an apple a day to keep the doctor away. You need a variety of nutrients to help keep your immune system on guard and you riding all winter long. While filling up regularly on plenty of colorful fruits and veggies will go a long way toward keeping your body and immunity running smoothly by maintaining the proper balance of the vitamins and minerals as well as the good bacteria in your gut that your immune system needs to function properly, the following foods can add extra cold and flu-fighting punch to your meal plan—and more miles to your season.

1. Yogurt

Probiotics, or the “live active cultures” found in yogurt, are healthy bacteria that keep the gut and intestinal tract free of disease-causing germs. Although they’re available in supplement form, a study from the University of Vienna in Austria found that 7-ounces of yogurt a day was just as effective in boosting immunity as popping pills. In an 80-day Swedish study of 262 factory employees, those who drank a daily supplement of Lactobacillus reuteri—a specific probiotic that appears to stimulate white blood cells—took 33 percent fewer sick days than those given a placebo. Any yogurt with a Live and Active Cultures seal contains some beneficial bugs, but Lactobacillus reuteri is harder to find so scan the ingredients labels for the exact strands.

2. Garlic

This potent onion relative contains the active ingredient allicin, which fights infection and bacteria. British researchers gave 146 people either a placebo or a garlic extract for 12 weeks; the garlic takers were two-thirds less likely to catch a cold. Other studies suggest that garlic lovers who consume more than six cloves a week have a 30 percent lower rate of colorectal cancer and a 50 percent lower rate of stomach cancer.

3. Chicken Soup

When University of Nebraska researchers tested 13 brands, they found that all but one (chicken-flavored ramen noodles) blocked the migration of inflammatory white cells—an important finding, because cold symptoms are a response to the cells’ accumulation in the bronchial tubes. The amino acid cysteine, released from chicken during cooking, chemically resembles the bronchitis drug acetylcysteine, which may explain the results of mitigating upper respiratory tract infections. The soup’s salty broth also keeps mucus thin the same way cough medicines do. Added spices, such as garlic and onions, can increase a soup’s immune-boosting power.
Recommendation: Have as many bowls as tolerable when feeling under the weather.

4. Fish

Selenium, plentiful in shellfish such as oysters, lobsters, crabs, and clams, helps white blood cells produce cytokines—proteins that help clear flu viruses out of the body. Salmon, mackerel, and herring are rich in omega-3 fats, which reduce inflammation, increasing airflow and protecting lungs from colds and respiratory infections.

Recommendation: Two servings of selenium-rich and/or omega-3 fatty fish per week.

5. Beef (or Protein Substitute)

Zinc deficiency is one of the most common nutritional shortfalls among American adults, especially for vegetarians and those who’ve cut back on beef, a prime source of this immunity-bolstering mineral. And that’s unfortunate because even mild zinc deficiency can increase your risk of infection. Zinc in your diet is very important for the development of white blood cells, the intrepid immune system cells that recognize and destroy invading bacteria, viruses, and assorted other bad guys, says William Boisvert, Ph.D., an expert in nutrition and immunity at the Scripps Research Institute in La Jolla, California. The good news is, you can also find zinc in non-meat sources such as dairy such as cheese, milk, and eggs or for vegetarians, nuts such as pine nuts, peanuts, cashews and almonds; hemp seeds, and legumes such as chickpeas, lentils, and beans.

6. Sweet Potatoes

You may not think of skin as part of your immune system. But this crucial organ, covering an impressive 16 square feet, serves as a first-line fortress against bacteria, viruses, and other undesirables. To stay strong and healthy, your skin needs vitamin A. “Vitamin A plays a major role in the production of connective tissue, a key component of skin,” explains David Katz, M.D., director of the Yale-Griffin Prevention Research Center in Derby, Connecticut. One of the best ways to get vitamin A into your diet is from foods containing beta-carotene (like sweet potatoes), which your body turns into vitamin A.
Recommendation: A half-cup serving, which delivers only 170 calories but 40 percent of the DV of vitamin A as beta-carotene. They’re so good, you might want to sprinkle with some cinnamon and save them for dessert! Think orange when looking for other foods rich in beta-carotene: carrots, squash, pumpkin, and cantaloupe.

7. Mushrooms

For centuries, people around the world have turned to mushrooms for a healthy immune system. Contemporary researchers now know why. “Studies show that mushrooms increase the production and activity of white blood cells, making them more aggressive. This is a good thing when you have an infection,” says Douglas Schar, DipPhyt, MCPP, MNIMH, director of the Institute of Herbal Medicine in Washington, DC.
Recommendation: Shiitake, maitake, and reishi mushrooms appear to pack the biggest immunity punch; experts recommend at least 1 ounce to 1.4 ounces a few times a day for maximum immune benefits. Add a handful to pasta sauce, or sauté with a little oil and add to eggs.


Science-Backed Benefits of Cycling Regularly

Fitness culture has (thankfully) become more prominent over the past decade, and taking care of our personal health and fitness has become standard practice for many of us. 
Mentions of fitness and exercise will often bring up thoughts of running, weightlifting, yoga, and other similar activities. And while cycling may be familiar to many, it’s sometimes overlooked as simply a means of commuting compared to other more popular physical activities.
That’s why it may surprise you to learn about the remarkable health benefits that cycling has to offer.
Cycling produces numerous health benefits to riders, and with countless studies providing evidence to support the many physical health gains that cycling has to offer, this well-established form of exercise is one you should definitely try out. 
In addition to physical health benefits, research has shown that cycling produces a great deal of mental health benefits and can reduce greenhouse gas emissions. To make our point, we collected the science-backed benefits of cycling.

Health Benefits of Cycling – science-backed

It’s almost hard to believe that simply pedalling a bicycle from Point A to Point B can lead to so many physical benefits, but the research shows that cycling produces an immense amount of health gains and fights off many health issues that are far too common in this day and age.

Cycling Boosts Your Immune System, Combats Obesity, and Aids Digestion

Health problems are all-too-familiar annoyances in everyday life but with cycling, many of those annoyances can be reduced and even prevented. 
According to multiple studies, including one from the University of North Carolina, riders who cycled for half an hour a day for five days per week used only about half of the sick days of those who performed no physical activity, leading to the conclusion that cycling keeps you healthier than non-active coworkers.
Cath Collins, the chief dietitian at St. George’s Hospital in London, explains what’s going on here, saying, “Moderate exercise makes immune cells more active, so they’re ready to fight off infection.”
In addition to preventing sickness, experts and studies show that physical activity, specifically cycling, is inversely associated with obesity, meaning that the more you cycle, the more fat you will burn. A study from the University of Copenhagen supports this by showing that inactive, overweight people can reduce their body fat just as effectively by riding a bike to work than by exercising in their spare time.
Cycling has even been shown to help digestive health. Dr. Ana Raimundo, a Harley Street gastroenterologist, has stated that “Physical activity helps decrease the time it takes food to move through the large intestine, limiting the amount of water absorbed back into the body and leaving you with softer stools, which are easier to pass.”

Cycling Will Help You Live Longer

People are familiar with the concept that exercise can add years to their lives but most fail to truly understand the amazing effects that exercise, especially cycling, can have on their longevity.
Bike Radar reports an interesting study conducted by King’s College London that showed a biological age difference of 9 years between twins that cycled and those who didn’t. 
Another study published in the International Journal of Sports Medicine found that the cyclists who participated in the Tour de France lived, on average, eight years longer than the general population.
Finally, cycling is so good for your heart that the NHS in the UK reports that cyclists have a 41% lower risk of death from any cause mortality than non-cyclists.

Cycling Prevents Serious Diseases

On top of helping you live longer, research has shown that cycling helps to reduce the risk of serious health complications, such as cancer and heart disease. 
The same NHS report referenced above notes that cyclists are 40% less likely to succumb to death by cancer.
Similarly, women who cycle have been shown to have a 34% less likelihood of developing breast cancer. 
Cardiovascular benefits are just as strong, with cyclists having a 52% lower risk of death from cardiovascular disease. Another study showed that picking up cycling, even after 43 years of age, helps to control cholesterol levels and prevent elevated blood pressure. 
Mothers-to-be might also benefit from cycling, with some experts suggesting that cycling helps women have an easier delivery, recover faster, and generally boosts mood during and after pregnancy.

Mental Benefits of Cycling – science-backed

The physical health benefits of cycling alone are impressive, to say the least, but they aren’t the only benefits cyclists can expect to enjoy. Research has shown that riders will enjoy a myriad of mental and emotional benefits from cycling.

Cycling Fights Depression, Anxiety, and Self-Esteem Issues

Some long-term studies show that those who reported high levels of activity in their daily lives were at significantly lower risk for depression. The therapeutic use of cycling to treat clinical depression has been shown to be effective, without the adverse side effects of pharmaceutical use.
And an analysis of other health studies has shown that lifestyle exercises, such as cycling to work, improved overall mood and mental health.
Other research shows that regular physical activity can even boost overall self-esteem.

Environmental Benefits of Cycling – science-backed

Environmental problems are a highly discussed topic in today’s modern landscape of global issues and with so many different plans and solutions being offered up, most seem to overlook a very simple solution: try to cycle more often.
It’s no secret that motor vehicles’ immense carbon emissions are quite bad for the environment. According to the EPA, a typical passenger vehicle emits about 4.6 metric tons of carbon dioxide in one year.
One person switching to cycling for transportation could, on average, reduce carbon emissions by almost five metric tons a year. If hundreds or thousands switched over, the environmental benefits would be massive.

Why and How You Should Try Cycling

Exercise is one of the most important factors in leading a healthy life, and as we said before, with so many different varieties, it can be difficult to choose the one that’s right for you. 
But if the research and evidence show anything, it’s that cycling offers a tremendous amount of physical, mental, emotional, and environmental benefits to those who try it. 
With such extensive gains, cycling might be right for you. 
Besides all of these health benefits, cycling also gets you from point A to point B while giving you moderate exercise and mental balance. (Not to mention that it’s probably the only exercise out there that lets you sit down the entire time!)

Does cycling strengthen your immune system?

When you think about it, our immune system does a remarkable job of defending us against disease-causing organisms. We take our immune systems so much for granted that we only really pay attention to it when a germ successfully invades, and we get ill. While the shelves are stocked with ‘miracle-pills’ that claim to boost our immune system, it turns out the solution may have been under our noses the whole time in the shape of two wheels and a saddle…

Why our immune system is incredible
Your immune system is your body’s natural defence against infectious agents such as viruses, bacteria, parasites, and even tumour and cancer cells. It’s even involved in your body’s response to injury and trauma. It does this by producing white blood cells and other chemicals that attack and destroy the foreign substance that’s made it past your body’s defences.
Your immune system can recognise millions of different antigens and deploy the appropriate tactics to eradicate nearly all of them. When it’s working as it should be, this impressive defence system can protect against health problems ranging from the common cold to cancer. So, if you’re feeling in tip-top shape today, take a moment to give your immune system some appreciation – it truly is amazing.

It all goes downhill with age

The bad news is the immune system declines by about 2-3% every year starting in our 20s, hence why we’re more susceptible to infections as we get older. This is because the thymus – one of the organs of the immune system and is where immune cells called T cells mature – begins to shrink when we’re young adults. By the time we’re middle ages, it’s only 15% of its maximum size, and since T cells are responsible for attacking harmful antigens you can see why our immune system suffers!
Don’t worry though as there are some advantages to getting older! As we age, our immune systems develop more defences against antigens. The reason being that we acquire antibodies to the germs we’ve defeated in the past, which is why adults suffer from fewer colds than children.

Where does cycling come into all this?

We’ve heard the bad news, but the good news is there’s a simple way to combat the decline of our immune system, and it’s something a lot of us are doing already: cycling. A recent study conducted by Aging Cell followed 125 long-distance cyclists, some were now in their 80s, and found they had the immune system of 20-year-olds.
They discovered that the long-distance cyclists were producing the same level of T-cells as adults in their 20s, compared to a group of inactive adults who were producing very few. As a result, the researchers believe that doing a physical activity such as cycling, will help people respond better to vaccines, and will be better protected against nasty infections such as the flu.
Not only that but because the cyclists have the immune system of someone in their 20s, they will have added protection against things such as rheumatoid arthritis and even cancer.

The long-term benefits of cycling on our immune system are very clear, but will we see any evidence of these immune boosts in the short term? The answer is yes. In the short term, it’s thought physical activity may help flush out bacteria out of your lungs and airways, therefore reducing your chance of getting a cold or flu. It’s also thought that our rise in temperature when taking part in a vigorous exercise like cycling may prevent bacteria from growing. The rise in body temperature helps our bodies fight infection better – this is why we get a temperature when we’re ill.
One thing’s for sure, getting on your bike for a scenic morning ride is a lot more enjoyable than queuing in your pharmacy for some cold or flu treatment. There’s never been a better excuse to get some miles under your belt – prevention is better than a cure, right?
