Vitamin C




Vitamin C plays an important part in the everyday function of our cells. It has many roles, some of which include helping with the healing of injuries, maintain the health of your teeth and gums, and helps your body absorb iron.1The most commonly advertised role of vitamin C is its ability to help with your immune system, but a common misconception is that vitamin C gets rid of colds. The truth behind that is that vitamin C can help prevent colds by building up your immunity or it can help with decreased the effects of a cold, but it does not rid you of it. 1 This is important to keep in mind because the human body can’t make its own vitamin C. 2
Mammals like goats, dogs, and cats can make vitamin C through their livers, but through time and many genetic mutations, human cells no longer can make it. 2 This is most likely due to humans were getting vitamin C readily from other sources like fruits and leafy greens so through out time, the need to make it went away. 2 The way genetic mutations usually work is that when you lose something that had a good function, you don’t survive, but the opposite was true with the stop in production of vitamin C in human cells. Apes, chimps, and gorillas also have the genetic mutation that doesn’t allow them to produce vitamin C, which might mean that our primate ancestors had the mutation first and it carried through to the human cells today. 2
Because of this mutation and the importance of vitamin C in the functioning of human cells, it is good to make sure you are getting enough. There is a lot of debate as to how much vitamin c a person need daily, but the most commonly used and recommended amount is 100mg-200mg a day along with a balanced diet.3

Sodium hypochlorite

Have a sneeze? Use some sodium hypochlorite!



Tired of having an itchy nose with the constant sneezing?

Your doctor telling you that your allergic to something called dust?


Worried that you might get asthma like your older brother?


Well have no fear; some good old bleach is here!!



Being allergic to almost everything in the house can be a pain because the home is where the heart is... not the pile of tissues! Studies have found that using bleach (sodium hypochlorite) as a disinfectant in the house can actually cure/calm many indoor allergies, while protecting against asthma and eczema1. But how can a simple white bottle sitting under that kitchen sink be so important? Let me explain! 

In 1785, a famous chemist known as Claude Berthollet created a wondrous chemical known as sodium hypochlorite; commonly known as bleach 2. He did this by mixing together chlorine gas with sodium hydroxide3. Initially this yellow tinted liquid was invented to fade out colours; but today we use bleach for other things such as a disinfectant. Sodium hypochlorite can be used as a disinfectant in swimming pools, antibacterial sprays, for nerve agent neutralization and at home3

The bleach found at home has a lower concentration (4-7%) of sodium hypochlorite in it3. This is because a higher dosage is not needed in order to effectively clean our homes! Our household bleach doesn’t just clean up dust, dirt and mold, but also kills some dangerous bacteria that can cause various infections3. Studies have found that families who clean their house with bleach have reported to catch less colds and flus4! They have also uncovered reduced risks of catching hay fever, calming down asthma attacks and eczema flares4.

Now with all good things there are always precautions. Don’t go too crazy cleaning your house with bleach, stay with the recommended amount that is 2-3 times a week4. As we know bleach is corrosive therefore it is essential to wear gloves when using this chemical! Don’t try to inhale it because that can cause many respiratory problems (something we are trying to prevent)5. Also, it is important to note bleach is meant for disinfecting surfaces, drinking it is a definite no as it can eat away your insides5.Bleach should never be mixed with other cleaning detergents because it can create dangerous chlorine gas!

Always remember it is still a chemical therefore needs to be handled safely. As long as the precautions are met, bleach is a great way to disinfect your house while keeping you healthy all year long!!
