Stressors are Friends not Foes

As final exams approach and deadlines are surmounting so is stress. Stress can be seen as both a good and bad thing depending on how you react to these situations that cause it. The dictionary describes stress as a state of mental or emotional strain or tension resulting from adverse or very demanding circumstances. This natural response of our body can trigger other response systems such as our immune system and fight-or-flight response.

For many years we have been told that too much stress is a bad thing. That chronic stress will decrease our lifespans and cause a host of other health issues including anxiety, high blood pressure, and depression. This still stands, as the more stress that you have in your body the more detrimental it is to your health as your body fills with epinephrine and cortisol. Epinephrine and cortisol effect your heart by changing the width of your arteries, contracting them so your heart has to work twice as hard to pump blood through your system.

Benefits of Stress:

However, there can be upsides to stress. But this involves a mind-shift, looking as stress as your body rising to the challenge you are presenting it with. It can help motivate you to complete your goals, accomplish tasks efficiently or even boost your memory. When you change the way that you think about stress it can be used as a benefit. Stress can also help you face fears and overcome challenges. The only downside to accessing the full benefits of stress is the major mind-shift that you would need to undergo. But if you can accomplish that then the negative effects that stress can do to your body are in fact mitigated. This major study done by Harvard University speaks to the benefits that stress can offer when you change your mindset.

In conclusion, stress can be your friend if you know how to use it.

Stop cheating yourself! Probiotics can’t treat your stomach flu

Imagine your cousin is terribly exhausted by a stomach flu that he accidentally got during the weekend, and he pukes everywhere. Which treatment would you choose? One pill full of probiotics so that they can fight away the ‘bad germ’ that roams your cousin’s gut? Or just a simple hot water bag and a bowl of thin soup? Which treatment do you think will help you get rid of the terrible puking faster? I bet most of you would choose to take the probiotics, since from what we learnt on the internet, probiotics are effective in fighting away the ‘bad germs’ that lies inside your gut. They can adjust your gut microbes, make your skin looks better, help you digest food more efficiently, and finally build a well-regulated and healthy gut environment. More importantly, they are not as merciless as the antibiotics, which will kill whatever left in the gut and leave a gut free of both good and bad germs behind. At least, that was what most videos on Youtube say about the benefits of probiotics.

However, is it true? Is it possible for just a small pill of probiotics to have the ability to save your gut? How good are these small, almost invisible to naked eyes creatures? The answer,unfortunately, is no. In the case of a gut inflammation caused by virus or bacteria, the probiotics can do nothing better than simple placebos. According to two recent big studies in the U.S., probiotics are inefficient in preventing the development of moderate-to-severe gut inflammation, and symptoms of the researched subject shows no difference against the placebo group.

One of the research mainly focused on Lactobacillus rhamnosus and L. helveticus, both are commonly used probiotics. Participants of this research are 3 to 48 months old children that has been diagnosed as gastroenteritis, commonly known as the gut flu or the stomach flu. In this study, participants were randomly selected and separate into two groups, one receives the probiotics while the other group receive the placebo for two weeks. At the end of the study, the outcome of the participants were evaluated to determine if the probiotics or the placebo had treated their illness.  Among all the participants who received the probiotics, 26.1% of them developed into a moderate-to-severe gastroenteritis, while 24.7% of the placebo group developed a moderate-to-severe gastroenteritis. This means that the probiotics is of no use in preventing the development of moderate-to-severe gastroenteritis.

So what exactly should we do when we are facing a gastroenteritis? And is it true that probiotics are all useless? Researchers have not given a clear answer yet. What is true is that next time when a stomach flu strikes, do not panic, before purchasing the expensive probiotics, keep asking yourself do you really need it.
