Loneliness May Increase Illness, Cardiovascular Disease Risk- Physicians Warn

Researchers in the field of public health have found that persons who live by themselves have an increased likelihood of developing cardiovascular diseases and other maladies.

The likelihood of developing melancholy, difficulties sleeping, and other negative health outcomes may be elevated in individuals who live a life of loneliness, according to medical experts.

They claim that being alone causes an excess release of stress hormones, which in turn leads to an increased heart rate, as well as higher blood pressure and blood sugar levels—all of which are conditions that are categorized as cardiovascular disorders.

According to the World Health Organization (WHO), cardiovascular diseases (CVDs) are an umbrella term for a variety of conditions that affect both the heart and the blood arteries.

The notion that cardiovascular diseases are the biggest cause of death worldwide has been lamented by global health.

The World Health Organization (WHO) reported that cardiovascular diseases were the cause of death for an estimated 17.9 million individuals in 2019, accounting for 32% of all fatalities worldwide. Of these deaths, 85% were attributed to heart attacks and strokes.

In an interview with PUNCH HealthWise, a professor of public health at the University of Ilorin, Kwara State, Professor Tanimola Akande, and a public health physician, Dr. Timothy Olusegun, said that loneliness also lowers the number of antibodies produced to fight infection. They noted that this may make the body more predisposed to cancer. Professor Akande is also a public health researcher.

According to Professor Akande, feelings of isolation can make mental problems, diabetes, and cardiovascular diseases more difficult to manage.

Based on him, the inactivity that is brought on by being alone has a tendency to make the individual hypertensive. Additionally, the individual does not burn carbs from food, and as a result, the individual has a tendency to be obese, along with the issues that come along with being obese.

The professor of public health pointed out that an inactive lifestyle can also be caused by feelings of isolation.

"Loneliness means that a person stays for a long time without interacting with other people, and this gives room for inactivity, little or no social interactions, and giving room for diseases that particularly affect the mental health of such individuals."

"Loneliness can lead to diseases such as cardiovascular (heart disease and stroke), diabetes, and mental health difficulties such as depression and anxiety, drug addiction, suicidal tendencies, and dementia. Cardiovascular ailments include heart disease and stroke.

"A person who lives alone is likely to be sedentary and to waste an excessive amount of time dwelling on troubling or fruitless ideas. Some illnesses, such as depression, can cause an individual to withdraw from social interaction, which can manifest as feelings of isolation in the sufferer.

The public health expert responded to the assertion that people who are lonely will always have a cold by saying, "This is not always the case. However, lonely people who stay indoors in cold or moist environments tend to have symptoms of colds like running nose."

"Those who choose to live solitary lives need to understand the risks to their health and give up the practice." People who notice that certain folks are lonely can also be of assistance by offering them advice to engage in frequent social interaction and by making an effort to spend time keeping them company.

According to Dr. Olusegun, persons who spend a lot of time alone produce more cortisol, and an excess of this hormone is what leads to inflammation and disease.

According to the physician who specializes in public health, feelings of social isolation and loneliness can raise the risk of death by as much as 30 percent.

He emphasized the fact that persons who are socially isolated and lonely are more likely to participate in behaviors that are detrimental to their health.

"This is a serious public health concern because loneliness affects everything; each and every facet of a person's health and well-being."

"When people are isolated and lonely, they have a tendency to consume more, not exercise as much, and get less sleep than they need. Their actions towards their health continue to deteriorate.

"Another finding from this research suggests that persons who report feeling isolated are more likely to participate in risky behaviors, in comparison to those who report feeling more socially connected.

According to what he had to say, "Adults who live alone have a 40% increased risk of developing dementia and other cognitive impairments."

Dr. Olusegun went on to say that persons who live alone are more likely to have chronic inflammation, which can result in a variety of health issues such as cardiovascular disease, type 2 diabetes, rheumatoid arthritis, and even cancer.

When our immune systems go into action to defend us from danger or disease or to cure us, one of the mechanisms that they use is inflammation.

This mechanism, when it goes wrong, results in chronic inflammation. The body continues to send out alarm signals even if there is no evidence of any harm or threat. This particular form of chronic inflammation is responsible for the development of chronic health disorders.

According to the findings of a study that was presented at the annual meeting of the National Academy of Sciences, being alone can modify immune system cells in a way that makes a person more susceptible to being sick.

According to the findings of a study that was conducted by John Cacioppo, who is a professor of psychology at the University of Chicago, along with colleagues from the University of California-Los Angeles and the University of California-Davis, it was discovered that older persons who feel intense loneliness had a 14% increased risk for passing away before their time.

The study was carried out by the researchers by analyzing the gene expression in the leukocytes of 141 individuals ranging in age from 50 to 68 who were participants in the Chicago Health, Aging, and Social Relations Study. Leukocytes are white blood cells that are part of the immune system and help the body fight off infections.

The research group discovered that those who experienced loneliness had higher levels of CTRA gene expression in their white blood cells compared to people who did not experience loneliness.

They also discovered that CTRA gene expression predicted loneliness evaluated at least one year later, whereas loneliness predicted CTRA gene expression measured one year or more later.

According to them, this demonstrates that leukocyte gene expression and isolation work together to make each other worse over time.

The gene expression in the leukocytes of rhesus macaque monkeys, which the researchers say are a highly social species, was also analyzed by the researchers.

The monkeys came from the California National Primate Research Center, which is a facility that is regarded as having a high level of perceived social isolation.

Not only did lonely monkeys have higher amounts of CTRA gene expression in their white blood cells, but they also had higher levels of the neurotransmitter norepinephrine, which is implicated in the "fight-or-flight" response that is triggered in reaction to stress.

In addition, a different study that was featured by Medical News Today found that feelings of isolation and loneliness are issues that apply to people of all ages.

Despite the fact that older individuals are more likely to be lonely and have a greater mortality risk overall, Brigham Young University psychologists in Provo, Utah, showed in a meta-analysis that loneliness and social isolation better predict premature death among populations aged less than 65 years. This was the case despite the fact that older people are more likely to be lonely.

For the purpose of this investigation, the researchers analyzed the data from seventy different studies that had been carried out between the years 1980 and 2014, with a total of more than three million individuals.

The data includes information about feelings of loneliness and social isolation, as well as living by oneself.

The researchers found that an increased risk of early mortality was associated with social isolation, even after controlling for characteristics such as age, gender, socioeconomic level, and pre-existing health disorders. This was the conclusion they reached after conducting their study.

On the other hand, it was discovered that having social contacts can have a beneficial effect on one's overall health.

However, the study did make use of data from a relatively small age span, with the vast majority of the information coming from people in their later years.

The authors of the study admitted that participants with an average age of 59 or younger made up fewer than a quarter of the research that were evaluated, and participants younger than 50 made up only nine percent of the studies.

The researchers, on the other hand, noted that the impacts on physical health caused by loneliness and social isolation are comparable to those produced by obesity, and that current evidence indicates that "Heightened risk for mortality from a lack of social relationships is greater than that from obesity."
