For centuries, many health myths have emerged in the community. Some have been tried, tested, and taken as facts, but others have nothing more than fantasy.
Health related myths are common and appear for various reasons. Some may be stories from ancestors that have been passed down from generation to generation.
At other times, it can be a science of the past but was received earlier, as the results of a study from the mid-20th century, discovered by modern scientific methods to be less accurate than originally thought.
There are five most common health myths that you need to know, as reported by Medical News today, the following.
1. Drink 8 glasses of water per day
The Center for Disease Control and Prevention (CDC) is unambiguous in this regard, stating that drinking enough water every day is good for overall health.
The question is, how much water is enough? The CDC notes that there are no guidelines for how much water to drink every day.
But, they are connected with the National Academy of Sciences, Engineering and Medicine , which says that women need 2.7 liters and men need 3.7 liters of total water per day.
The total water point is very important; this does not refer to how many liters of water you have to drink, but about how much water you consume from different drinks and foods.
It’s important to note that the average total water intake of people drinks, including caffeinated drinks, make up about 80 percent of their total water intake, with the remaining 20 percent actually coming from food.
Many people believe that the recommended amount of daily water is eight glasses, equal to 2.5 liters.
This number does not take into account the amount of water we get from drinks or other foods at all. This number does not appear in official or scientific United States guidelines on water consumption. So why do so many people believe in this suggestion?
A 2002 study claimed eight glasses per day – known daily 8 × 8 – returned a misinterpretation of one paragraph in the 1945 government report.
In it, the Food and Nutrition Board of the National Research Council wrote, “The right water requirement for adults is 2.5 liters per day. The usual standard for a variety of people is 1 milliliter for each food calorie. Most of this quantity is contained in fast food. “
As a recommendation, this doesn’t seem too controversial, and it really seems more or less in line with what was said by the National Academy of Sciences, Engineering and Medicine in 2018.
But the author in 2002 believed that people only pay attention to the first sentence, and over time, they ignore statements about foods that contain water. This then led to the very wrong impression that 2.5 liters of water should be consumed every day beside any water we drink from other drinks and food.
Most importantly, the authors of this study found no scientific evidence to support the 8 × 8 theory in terms of health benefits.
2. Cold temperatures cause flu
Although historically, people assumed that cold temperatures caused people to catch colds . Nowadays, people are generally more aware that you have the flu not because you are in bad weather, but because of a virus.
A person is infected by a cold virus, known as rhinoviruses, through physical contact or in the same room as an infected person.
This is especially true if an infected person coughs or sneezes, or if we have touched several objects that have been touched by an infected person.
So, it seems pretty clear that the cold temperatures that cause people to catch the flu are myths. The mechanism that becomes cold can actually make us more susceptible to colds.
Cold viruses try to enter the human body through the nose, but they are usually trapped in mucus. Usually, mucus returns to the body, is swallowed, and the virus is neutralized by stomach acid.
But when we breathe cold air, the nasal passages become cold. This slows mucus movements, and this means that live rhinovirus has more opportunities to penetrate the mucus barrier and enter the body.
The study also found that cold viruses develop in colder weather, because they are less able to survive at normal body temperature.
So, it’s mostly caused by viruses and not just the consequences of cold weather.
3. Squeezing fingers can cause arthritis
Squeezing fingers does not cause arthritis. They generally report that people who squeeze their fingers at risk are almost the same as arthritis, like those who have never experienced arthritis. So, not squeezing your fingers will not increase the risk of arthritis.
When we squeeze our fingers to make a sound, the researchers explain, we pull our joints slightly, which causes decreased pressure on the synovial fluid that lubricates the joint. When this happens, bubbles form in the liquid.
Pressure variations cause fast-fluctuating bubbles, which create a distinctive cracking sound, which is very fun when massaging, right?
4. Deodorants can cause breast cancer
Some people suggest that there might be a connection between the use of deodorants and the development of breast cancer. This is based on the assumption that chemicals from deodorants affect breast cells, given that they are applied to nearby skin.
Nearly all studies that have tested this have found little evidence to support claims that deodorants can cause breast cancer.
One retrospective study revealed that breast cancer sufferers who use deodorants are regularly diagnosed as younger than women who do not regularly use them.
But because this is a retrospective study, the results cannot prove the relationship between deodorant use and the development of breast cancer.
The National Cancer Institute said that additional research would be needed to prove that the relationship between the use of deodorants and breast cancer.
5. Eggs are not good for the heart
Since the 1970s, there has been a strong focus on health care caused by cholesterol in heart disease. Eggs are rich in nutrients, but they also have the highest cholesterol content of ordinary foods.
Because of this, some people recommend that we eat only two to four eggs per week, and that individuals with type 2 diabetes or a history of heart disease should eat less.
But new research shows there is no connection between eating lots of eggs and cholesterol imbalances or an increased risk of heart problems and type 2 diabetes.
The study notes that sometimes, people who eat more than seven eggs per week increase low-density lipoprotein cholesterol, or “bad” cholesterol, but this is almost always matched with an increase in similar high density lipoprotein cholesterol, which has protective properties.
Evidence shows that eating two eggs every day is safe and has a neutral or slightly beneficial effect on risk factors for heart disease and type 2 diabetes.
According to the CDC, eggs are one of the most nutritious and economical foods offered by nature, and that the main health risks posed by them are the risk of Salmonella infection. The CDC provides guidance on how to best avoid Salmonella.
Well, Healthy Friends, still believe in some of these myths?
