Energy Drinks And Health Effects

The consumption of energy drink is common in all age groups and is significantly increasing. Energy drinks are almost available in all countries in different brands. It is assumed by most people that drinking it, is safe and guarantees its purpose which is giving energy but the health effects are mostly forgotten.  The health effects can range from mild to severe or even dead. Even with all the health issues, the energy drink market will increase to about $21 billion in annual sales by the end of 2017.

The health effects of energy drinks are cardiac arrest, headaches, type 2 diabetes, vomiting, high blood pressure, increased anxiety, insomnia, risk behaviour and nervousness. It has been reported in the United States that due to energy drinks there have been 18 deaths, 150 serious injuries and the number of hospital beds doubled, from 2004 to 2012. The health issues of energy drinks are clear but still the consumption of it, keeps increasing and reasons might be that people either ignore the facts or they need to be educated. In the United States, the consumption of energy drinks have always been on a rise and it is expected that from 2014 to 2019 it will increase up to 52%, which is an enormous amount.

Internationally, energy drink market has raised by 15% and will continue to increase. Surprisingly, the largest consumer is Latin America and interesting North America is the second lowest.

Energy Drinks Shows Impressive Stamina

The customers of energy drinks are almost everyone ranging from teenagers, adults and maybe even kids. Also, it is consumed by male and female. It is found that 66% of energy drink consumption are by people ages 13 to 35. But it is considered that males consume it more than females. In a study by Nowak and Jasionowski, they had 1481 female and 1148 male participants from which they concluded that males usage of energy drinks are higher than females. It was found that 60.8% females and 74.5% males, consumed energy drinks. An interesting fact found in the study was that about 21% of teenagers took energy drink for no specific reason whereas it is mostly taken for the reasons of tiredness, physical activity or caffeine consumption. 

One sad story related to energy drinks was in the case Lanna Hemann, a 16-year old who died from consuming the drink while being on vacation without her parents. To make the long story short, she consumed an energy drink from which she went into cardiac arrest and passed away.

In conclusion, the consumption of energy drinks is related to many health issues which may result in even death. With the increase in energy drink market, it possesses a risk to everyone but especially young people because they might not be aware of the health effects. Therefore, avoiding energy drinks completely is the best way to live a healthier life.

Are Electric Cars Better?

As we all know, Earth is the only planet known to this date which supports life. There is no other planet in this humongous universe which has the qualities of Earth, such appropriate level of oxygen, moderate temperatures and most importantly water. So, keeping our home, Earth, suitable to live should be the first priority but unfortunately, we are destroying it by emitting a tremendous amount of Carbon dioxide (CO2) from driving vehicles. According to  International Council On Clean Transportation, the CO2 emission has decreased from 2012 to 2015 by a small amount but they are looking to reduce it much more by 2020. In 2012, the average CO2 emission for a 1400 kg passenger vehicle was 132 g/km and 130 g/km in 2015 but they are trying to reduce it to 90 g/km by 2020. In 3 years, they were able to reduce CO2 emission by only 2 g/km and by 2020 there is no guarantee of it being reduced by 30 g/km.

So, a better option is having electric cars, which does not use any gas and saves on CO2 emissions. Electric cars get their fuel from electricity generated by coal, natural gas, hydro, nuclear and wind. So, the CO2 emissions in electric cars are from the electricity source. According to the U.S. Department of Energy, electric cars use the least and gasoline use the most amount of CO2 according to national averages. Annually, electric cars used 5,000 pounds of CO2 equivalent compared to gasoline cars which use 11,658 pounds of CO2 equivalent.

Also, driving an electric car is much cheaper than a gasoline car. According to Transport Canada, traveling 210 km per week at $1.00 gas price, will cost $12.60. But traveling the same distance in an electric car will cost $3.15 with electricity being at 1.5¢ per kilometer. So, driving an electric car can save $9.45 per week and it produces much lower CO2 numbers. Also, it lowers the health and environmental risks associated with higher amounts of CO2 in the atmosphere.

Health risks associated with higher amounts of CO2 in the atmosphere can lead to shortness of “breath, deep breathing, headache, dizziness, vomiting and even death.” Although, emissions of CO2 are lead by major factories as well but gasoline cars are also considered to be a main source.

Carbon dioxide emissions cause environmental issues as well. According to Environmental and Climate Change Canada, CO2 results in melting of glaciers, warmer temperatures, heat waves, burning of forests and heavy precipitation. Also, the environmental changes due to CO2 emissions are dangerous to humans, such as the melting of glaciers will lead to higher sea levels  which can kill lots of people and leave many homeless.

In conclusion, driving electric cars reduces CO2 emissions leading to less health and environmental issues. Also, electrics cars tend to save money which can be used elsewhere.

Will Human Head Transplant Work?

Science has advanced very much in the field of medicine with discoveries that give people another chance to live. In the past century, there have been many new inventions including new medicines, vaccinations and organ transplant in humans. However, the idea of a head transplant was only a mystery which was only seen in movies such as Frankenstein. Surprisingly, that fiction is about to become a reality in the near future. In the next year or two, Italian neurosurgeon Sergio Canavero is to perform the first ever human head transplant which will evolve science to new echelons.  According to Canavero, the surgery is intended for those who have a fully functioning head, but endure a paralyzed body from the neck down due to some type of incurable disease or injuries suffered from accidents. The healthy head will be placed onto a healthy body of someone who is brain dead, and there is “90 percent” chance for the surgery to succeed.  Similar to other complications, “of course there is a marginal risk” according to Sergio Canavero.

The surgery of head transplant never performed before, and with the risks being higher than any other normal standard operation, Valery Spiridonov, a Russian computer scientist is willing to be the first patient. Spiridonov suffers from a motor neuron disease called Werdnig-Hoffmann Diseasewhich leads to the shrinking of the muscles every day and can cause difficulties breathing and swallowing. Currently, there is no cure for the disease and the head transplant can be a potential cure in the near future. Head transplant can also be a cure for those suffering from spinal cord injuries due to accidents, such as car crushes, falling from heights and others.

The estimated time for the operation is about 36 – 72 hours, with about 80 surgeons involved, and the estimated cost to be about 11 million British Pounds which is $15 – 16 million US dollars.  The procedure of the operation will involve, first cutting the head of the patient with a really sharp blade, then using special surgical glue called polyethylene glycol, to attach the head into the new body and then stitching up the blood supplies. Afterwards, the patient will be put into coma for about four weeks to allow the head to heal with the new body, and small electric shocks given in order to improve the flow of connection. After the patient wakes up, everything is expected to be normal such as the functioning of the senses and movement coordinations. If this operation succeeds, more people could experience a second chance at survival and a new life. For a detailed procedure, please read this.

In conclusion, I think head transplant operation is another step towards expanding science and with its success, it can give lots of people hope and perhaps a new life to look forward too.
