Top 10 Frequently Encountered Misconceptions Concerning Water

1 2

The reason why so many people are confused regarding whether or not they should drink water, what type and how much, resides in the conflicting information that is widely accessible on the internet nowadays. While the medical community advocates one thing, you will also be able to find exactly the opposite suggestions somewhere else. Most misconceptions arise from the misinterpretation of the doctor’s advice and here is a short top ten list for the most frequently encountered ones. However, keep in mind that this specific list is not exhaustive and you should consult with your physician for further clarifications.

 

1. The 8 glass of 8 ounce per day rule always applies for everyone

This myth most likely originates from the RDA recommendations issued more than 50 years ago, but more recent studies indicate that the 8 glasses of water is not exactly the optimal quantity. Specialists suggest that you should aim to ingest approximately 12 glasses of 8 ounces of liquid (irrespective of its provenience, be it juice, fruit, vegetables, etc.). The researchers from Institute of Medicine who issued these recommendations also advise increasing the quantity in accordance to the intensity of the daily physical effort and excessive heat that determines more perspiration.

 

2. Tooth decay is primary determined by drinking bottled water

Well, tooth decay is more of an indirect effect of the widespread bottled water consumption. The origins of this misconception come from the association of the higher occurrence of dental cavities with the popularization of the bottled water. Because the substance known as fluoride is not present in bottled water as it is in its tap counterpart and due to the fact that fluoride helps in mineralizing the teeth, it is easy to understand the roots of this myth. However, the fluoride deficiency can be compensated by switching to a brand of toothpaste that contains a higher quantity.

 

3. Drinking water is directly responsible for skin moisture

The effects of water on the moisture levels of the epidermis are negligible at best. The only time when there is a clear link between them is when you are experience severe dehydration. In fact, the dryness/moisture levels of the skin are influenced by external factors and in an extremely low percentage by the internal ones.

 

4. The proper water consumption has no influence on weight loss

It is fairly true that water has no direct impact on the person’s weight, but the indirect effects are definitely real. For example, when you switch from beverages with a high amount of calories to water, you will be able to quench your thirst without adding to your weight. In addition, water has the ability to make your stomach feel full, making it less tempting for you to eat at random points of the day. Take into account the cleansing properties and the ability to hasten the metabolism and you can easily understand the link between water and weight loss.

 

5. Drinking water during your meal has a negative impact on digestion

The theory that water should not be included in your meal and that you should wait a bit to drink water after you eat have absolutely no scientific basis. In other words, there is no hard evidence to support them. These ideas most likely come from the fact that diluting the gastric acid slows down the digestive process, but they have not been proven so far. Therefore, researchers even recommend that you drink one glass with your meal, because you will feel full faster.

Top 10 Most Dangerous Aquatic Species

1 2

Of all the aquatic species that have the power to cause the death of humans, this list compiles the ten most dangerous of them. The modus operandi of all of these animals may be very different – yet each one of them is what we would call ‘dangerous’.

 

1. Box Jellyfish (Chironex fleckeri)

Although ‘box jellyfish’ denotes the entire Cubozoa class, the most dangerous of them all is the deadly Chironex fleckeri. The venom of this species is the most deadly in the animal kingdom and is reported to be able to kill 60 humans within a period of 3 minutes.

 

2. Yellow Bellied Sea Snake (Pelamis platurus)

The venom of this dangerous sea snake is several times more potent and deadly than the most venomous land snake. The bite itself is painless and may even go unnoticed by the victim. Symptoms start showing around after half an hour of the bite, and if immediate medical attention is not received, the victim goes into cardiac arrest after six to twelve hours.

 

3. Saltwater crocodile

Crocodiles are territorial and they do not like intruders. They have been known to attack small boats and canoes and result in human deaths. Though you may argue that this is not exactly an aquatic animal, it hardly matters when you are been attacked by in water.

 

4. Great White Shark (Carcharodon carcharias)

All of us are familiar with the Great White – the popular star of the movie “Jaws”. Great Whites are expert hunters and know how to immobilize prey and render them helpless while they finish them off. There are reported incidents of Great Whites being responsible for the deaths of innocent swimmers off the coast of USA.

 

5. Blue-Ringed Octopus

This common name refers to several octopus species of the genus Hapalochlaena – small and beautiful octopuses that have a venom powerful enough to kill humans.

Top Ten Geysers

1 2

You can find Geysers in several parts of the world, in various land conditions and different climates. Iceland has several geysers in a barren lava field. Also there are several geysers in New Zealand amidst lush jungles. Yellowstone National Park in the U.S.A. has more than 200 active geysers. “Old Faithful,” the most notable geyser here erupts every 65 minutes for about four minutes, and this natural phenomenon has been happening for nearly eighty years without a miss. Its water can reach up to a height of 120 to 150 feet.

 

1. Old Faithful

Old FaithfulThis is a cone geyser which can be found in Wyoming, in Yellowstone National Park in the United States. Old Faithful was named in 1870. This geyser along with the Old Faithful Inn, is part of the Old Faithful Historic District.

 

2. Steamboat Geyser

Steamboat GeyserThis geyser in Yellowstone National Park’s Norris Geyser Basin, is the tallest active geyser in the world. Water may rise up to 300 feet into the air during major eruptions. Steamboat’s major eruptions are followed by powerful jets of steam.

 

3. Excelsior Geyser

Excelsior GeyserThis is basically a hot spring in the Midway Geyser Basin of Yellowstone National Park in the United States. This geyser discharges 4,000 to 4,500 gallons 93 °C water per minute. It was an active geyser till 1890 which erupted to 300 feet high.

 

4. Splendid Geyser

Splendid GeyserThis notable geyser is located in the Upper Geyser Basin of Yellowstone National Park in the United States. This geyser is a part of the Daisy Group and its eruptions are unpredictable and infrequent. During eruptions, it can reach a height of 200 feet.

 

5. The Great Fountain Geyser

The Great Fountain GeyserThis is a fountain-type geyser situated in the Firehole Lake area of Lower Geyser Basin of Yellowstone National Park, Wyoming. This geyser is the only predicted geyser in the Lower Geyser Basin and erupts every 9 to 15 hours. Its maximum height is about 75 feet to over 220 feet.

Top 10 Dams By Height

1 2

Barriers which are built across flowing water, such as rivers or large streams, are called dams. These barriers help us to utilize the power created by the rapid flow of water for generating hydro-electricity and the water itself for irrigation. When the flow of water is restricted, collecting in a single area, this forms a reservoir. Dams are also built to protect the surrounding areas from being flooded. In nature, dams are also built by beavers, to protect their homes and young ones from dangerous predators.

 

1. Rogun Dam
The Rogun DamThe highest dam ever built is the Rogun Dam, across the Rover Vakhsh in the southern part of Tajkistan. There were initial problems in building this dam and the project was shelved temporarily. However, later on a partnership was formed with Russia in order to complete the project, accomplished in 1990. This dam is 335 meters high, with a summit length of 660 meters, making it the highest dam in the world today.

 

2. Nurek Dam
The Nurek DamThe Nurek Dam stands next to Rogun Dam on the Vakhsh River. Located in Central Asia this is the world’s largest rockfill dam and, at a height of 300 meters, is amongst the highest in the world as well. Constructed between 1961 and 1980, it has 9 units generating hydroelectric power. These units were installed between 1972 and 1979.

 

3. Xiaowan Dam
The Xiaowan DamConstruction on the Xiaowan Dam was started in January of 2002, and continues today. This hydroelectric arch dam, on the River Lancang in south west China, is going to be one of the highest dams in the world, coming in third after the Rogun and Nurek dams, with a completed height of 292 meters. It is also going to be the world’s second largest dam in terms of hydroelectric power. The 6 power-generating units will each have a 700 MW capacity.

 

4. Grand Dixence Dam
The Grand Dixence DamBuilt to hold back Lac Des Dix in Switzerland, the Grand Dixence Dam is the highest dam in Europe. It is 4 kilometers long and 285 meters high. When it is full, the depth is of 284 meters and it holds 400 million cubic meters of water. Though the River Dixence is one of the smaller rivers in the area, water collects here in large quantities due to tunnels which bring in water from other sources. The lake is at its maximum depth in September.

 

5. Inguri Dam
The Inguri DamA hydroelectric dam, Inguri is in the country of Georgia. With a height of 272 meters, it is amongst the highest dams in the world. The Inguri Power Station is located in Abkhazia with the dam is built on the Inguri River. Construction of this dam began in 1961 however it was competed only in 1987. There are five generators at the Inguri Power Station.
