This is the day you are most likely to have a heart attack: Study

(Asian News Hub) – Heart diseases affect millions of people and are the second biggest cause of death across the globe.

Each year, millions of people die due to a heart attack, which happens when something blocks the blood flow to your heart, so it doesn’t get the oxygen it needs.

Also known as myocardial infections, symptoms of a heart attack include discomfort, pressure or pain in your chest or arm, indigestion, discomfort, sweating, upset stomach, vomiting, severe weakness, anxiety, fatigue, fast or uneven heartbeat.

However, symptoms can vary from one person to another. However, it can be difficult to predict when a person is most likely to suffer from a heart attack.But a particular study has found the answer to this complicated question (to some extent). 

Monday Is The Day People Might Get A Heart Attack

But scientists have been successful to find about the day when most people might get a heart attack – MONDAY!

As per the study published in the American Heart Journal, most people are prone to getting a heart attack on a Monday. For the study, researchers analysed data from more than 1,56,000 hospitals for heart attacks for a total of seven years.

The findings revealed that the chances of having a heart attack elevate when a person is stressed, and Monday is considered to be a stressful day for most people. World Heart Day 2020: What it takes to live a heart-healthy life?

As per the study results, the rate of myocardial infarction (MI) was greater during the winter holidays or on Mondays. They also found that the chances of a person getting a heart attack are lower on weekends and during summer vacations.

The results show that people are at an 11 per cent higher risk of getting heart attacks on a Monday than any other day of the week.

Why Mondays?

Another reason could be your body’s clock is not aligned with your routine. Your body’s internal system us governed by a master clock called the circadian rhythm, which is responsible to keep your body in sync with the day and night cycle.

When or behaviour is out of sync with our internal clocks, it can lead to health problems, including a heart attack. This may also help explain why heart attacks are more likely to happen on a Monday.

According to Harvard Health, people tend to stay up later than usual on a weekend and then sleep late when the next day starts. It is a phenomenon known as ‘social jet lag.’ This causes a delay in the circadian rhythm because, on a Monday, you force your body to wake up on time. This misalignment can lead to elevated blood pressure levels and lead to changes in the nervous system function, which makes people more vulnerable to heart attacks.

Stress on a Monday is one of the biggest factors that could lead to a heart attack. When your stress levels are high, it causes the amygdala (part of the brain) to spike, which may trigger the bone marrow to produce more immune cells to fight stress. This could lead to inflammation, which, in turn, could hurt your arteries and heart.

What Can You Do?

As mentioned, one of the biggest contributors to heart diseases is unhealthy habits that throw your body’s natural rhythms out of whack.

Certain things you need to keep in mind include:

  • Eat a healthy diet that contains all nutrients
  • Avoid exposure to nighttime light exposure that may suppress the release of melatonin and disrupt your sleep
  • From eating to sleeping to waking up, make sure you stick to a schedule
  • Exercise regularly
  • Try deep breathing or meditation

Serosurvey would determine impact of possible 3rd Covid wave on children: DAK

(Asian News Hub) – Doctors Association Kashmir (DAK) on Saturday said serosurvey of pediatric population in the valley would determine the impact of possible third Covid-19 wave on children.

Serosurvey of children will give us a fair estimate of their vulnerability in predicted third wave,” said DAK President and influenza expert Dr Nisar ul Hassan.

“Serosurvey involves testing blood samples of individuals for antibodies that are developed after an infection,” he said.

“This will give us an idea about the percentage of pediatric population who might have developed natural immunity.”

Dr Hassan said recently, a serosurvey of general population including children aged 7 to 17 years has been completed in Kashmir, the results of which are awaited.  The sample size per district in the age group 7 to 11 was 40 and it was 80 in 12-17 age group.

“The survey needs to be extended to the age group of 0 to 6 years and the sample size per district should be 500 to 1000 to get a clearer picture of the actual percentage of children who have developed immunity against Covid-19,” he said.

Dr Hassan said there are speculations that children would be affected more than adults in possible third wave as this is the population group in which there is no vaccine yet.

“However, various serosurveys have dismissed the claim that the next wave will be affecting children exclusively,” he said.

“A pediatric serological study conducted by AIIMS, New Delhi at five different sites found that 55.7 percent children had developed antibodies,” DAK President said.

“The study found that seroprevalence of children and adults in the same regions were almost similar.”

“Another study conducted by PGI Chandigarh revealed that 69 percent of children had antibodies against Covid-19,” he said.

“These children had remained either asymptomatic or mildly symptomatic during the infection.”

“The data of the two surveys prove that children have acquired natural immunity against the virus and it is highly unlikely that the third wave will affect children more than adults,” said Dr Nisar.

“This is a big relief. Because the apprehensions expressed by several health experts about the third wave primarily targeting children had left people worried,” he said.

“But, we can’t derive conclusions on the data from other regions. We need to have our own data based on which decisions can be made ahead of the feared third wave,” he added.

Israel reports Pfizer COVID-19 vaccine effectiveness against infection down to 40%

(Asian News Hub) – The Health Ministry said Thursday that the effectiveness of the Pfizer COVID-19 vaccine in preventing infection and mild symptoms has dropped to 40%, according to new data collected over the past month as the delta variant spreads in Israel.

In a televised address, Prime Minister Naftali Bennett meanwhile called on Israelis who haven’t been vaccinated to do so as soon as possible.

“The Israeli government is investing billions so that there is a vaccine available in every location in the country, and there are still a million Israelis who simply refuse to be vaccinated,” he said. “The vaccine refusers are endangering their health, their surroundings and all Israeli citizens. If a million Israelis continue to be unvaccinated, this will force the others to shut themselves in at home.”

The effectiveness of the vaccine in preventing hospitalizations and severe symptoms stands at 88% and 91%, respectively, the ministry said.

Scientists discover more than 30 viruses frozen in ice, most never seen before

(Asian News Hub) – A group of scientists discovered ancient viruses frozen in two ice samples taken from the Tibetan Plateau in China, and most of them are unlike anything ever seen before.

The findings, published Wednesday in the journal Microbiome, came from ice cores taken in 2015 that scientists said began to freeze at least 14,400 years ago.

“These glaciers were formed gradually, and along with dust and gases, many, many viruses were also deposited in that ice,” Zhi-Ping Zhong, lead author and researcher at the Ohio State University Byrd Polar and Climate Research Center, said in a statement. “The glaciers in western China are not well-studied, and our goal is to use this information to reflect past environments. And viruses are a part of those environments.”

When researchers analyzed the ice, they found genetic codes for 33 viruses. Of the 33, genetic codes for four of them showed they are part of virus families that typically infect bacteria. Up to 28 were novel, meaning they had never before been identified.

The group said it doesn’t believe the viruses originated from animals or humans but came from the soil or plants. The scientists said roughly half of them survived because of the ice.

“These are viruses that would have thrived in extreme environments,” said Matthew Sullivan, co-author of the study and director of Ohio State’s Center of Microbiome Science.

“These viruses have signatures of genes that help them infect cells in cold environments – just surreal genetic signatures for how a virus is able to survive in extreme conditions.”

Sullivan said the technology used to study microbes and viruses inside the ice would lead to looking for similar genetic sequences in other extreme ice environments, possibly on Mars.

Senior author of the study Lonnie Thompson said the discovery of the viruses in glaciers of ice will help researchers understand how they respond to climate change.

“We know very little about viruses and microbes in these extreme environments and what is actually there,” Thompson said. 

“The documentation and understanding of that is extremely important.”
