Is exercising with a cold harmful?

As the seasons change from summer to fall, the first thing that usually happens is the decrease in temperature which then leads to people getting the common cold. The common cold is usually just a neck cold, which in other words is a runny nose, clogged sinuses and a mild headache. People with the common cold are told that the best cure for it is rest so that the immune system is at its best, but what about those people that cannot rest and feel they need to be in the gym? I can help with that.

Some of the best exercises to do when you have a cold are walking, jogging, Qi gong, yoga and dance. Walking and jogging are considered to be good exercises because they are fairly low intensity, which means that it will not put much stress on your body, allowing your immune system to function at a high rate, and it clears your head while breaking a sweat. Qigong is an exercise that is a cross between martial arts and yoga that enhances the blood flow in your body and permits the immune system to be working at a high standard. Dance is also low impact and it lowers the cortisol levels in the body, which then will let the immune system to work at a greater level.

The worst exercises to do when you have a cold are endurance running, lifting weights, using machines at the gym, and team sports. Endurance running and lifting weights are bad because they are high intensity exercises and require a lot of your body’s resources to do these exercises, which leads to the decrease in energy put towards the immune system. Using machines at the gym and team sport are not good because these just influence the spread of the cold.

 

Having a cold is not a good enough excuse for sitting on the couch and watching the TV, so get out of bed and go for a walk or a jog to clear your head, but avoid going to the gym so that you are not the reason that everyone in the gym is sick. Here are a couple of simple yoga poses to help with your cold.

Imagination: Where Does It Come From?

You have probably seen this image on the left before. You might even have taken a personality test that identify you as a “logical left brainer” or a “creative right brainer”. Well, throw all those out the window because science has found a breakthrough in finding the origin of imagination.

 

As one of the oldest scientific myths,  people have identified themselves with the terms left-brained and right-brained with an assumption that some people use a particular side of brain more. Oh, you are logical and well-structured? You must be a left-brainer. Oh, you are creative and full of imagination? You must use your right brain a lot!

Through an extensive two year study, University of Utah researchers have completely busted this myth with identifying the specific networks in our  brain that process lateralized functions. We define lateralization as one hemisphere of the brain being more specialized in certain mental functions than the other. Based on the scanning images of 1,011 people’s resting brain, researchers studied functional lateralization in thousands of brain regions. They found that no individuals use their left brain network nor right brain network more as default.

For more information, this following Youtube video summarizes it perfectly.YouTube Preview Image

While these Utah scientists thoroughly proved that there is not left brain or right brain dominance in regards to creativity or logic, the origin of imagination is still unclear. The team who solved this mystery are the researchers from Dartmouth. They hooked the study participants up to fMRI and asked them to complete creativity related tasks, such as arranging shapes into complex patterns. The following is the fMRI image produced.

 A wide variety of neurons are activated to complete these tasks, but  as you can see,  the eleven highlighted regions of the brain distinctively made a clear “mental network” to generate imagination.

These eleven areas of the brain ARE the origin of imagination.

You may ask  that why is imagination important ? Spongbob here proves the point.

Befriending Fat In Your Diet.

This is what I ate for breakfast today:

Breakfast of Champions

That is almost 1000 delicious calories coming mostly from fat and protein. Did I mention I cooked it in butter?  Speaking of butter, I actually used to add multiple tablespoons of unsalted butter to my morning coffee instead of the usual cream and sugar.

For anyone having a minor heart attack just reading this and also wondering how I am not morbidly obese, prepare to be educated on the health benefits of a high fat diet.

“Science has proven that saturated fat has been wrongly demonized by the medical establishment for decades” – Yoni Freedhoff, Family doc., Assistant Prof. at the University of Ottawa, and founder of Ottawa’s Bariatric Medical Institute.

You too can have plenty of fat in your diet while staying healthy. Choosing to eat more fat instead of other macronutrients does not cause fat accumulation because weight gain/loss is mainly dictated by a person’s daily energy balance of calories consumed versus calories expended.  Other common misconceptions about high intake of dietary fat, include atherosclerosis (clogging your arteries), high cholesterol levels, and increased heart attack risk. However, as Mark Sisson, a highly prominent health author and blogger, points out, these are usually complex issues which correspond to one’s overall lifestyle and health and depend on many more risk factors. On the other hand, some beliefs are just completely wrong, for example, the Harvard School of Public Health notes that dietary cholesterol does affect total blood cholesterol at all, and this review published by Djousse and Gaziano in Current Atherosclerosis Reports concludes that “there is little evidence supporting a major association between dietary cholesterol and coronary heart disease risk in the general population”.

“Fat is not the problem,” says Dr. Walter Willett, chairman of the department of nutrition at the Harvard School of Public Health. “If Americans could eliminate sugary beverages, potatoes, white bread, pasta, white rice and sugary snacks, we would wipe out almost all the problems we have with weight and diabetes and other metabolic diseases.” – Sara Novak, Discovery Channel Fit & Health

With most of dietary fat’s falsely believed downsides out of the way, let’s talk about all of the health benefits of increased fat intake. Fat can be very nutritious. For instance, many sources of dietary fat such as egg yolks, butter and olive oil are also the richest sources of nutrients like choline, vitamin K2, and vitamin E, respectively. Mono- and poly- unsaturated fat’s, like those found nuts, plants, and oils, decrease your risk of heart disease as pointed out by the Mayo Clinic. Finally, my favorite benefit of a high fat diet is the increased testosterone, due to my hobby of weightlifting and testosterone’s beneficial effects on recovery and performance as shown in this article published in the Huffington Post.

My favourite cooking oil, coconut! A healthy source of saturated fat.
