It's been proven: too much stress may speed up the development of cancer cells! If there are 8 signs, it's time to reduce stress

In the blink of an eye, the new crown epidemic has been breaking out for more than 2 years, and during the prevention and control period, people are inevitably anxious, nervous and panic ...... and numerous negative emotions are making people more and more mentally stressed.

In June, the World Health Organization released its World Mental Health Report 2022, which showed that approximately 1 billion people worldwide will suffer from mental health disorders in 2019; in 2020, the year of the new crown pneumonia outbreak, there was a 25% increase in depression and anxiety worldwide alone.

What damage does increasing stress do to the body? How can we effectively relieve? This article may be able to give you some inspiration.

It's been proven: too much stress may speed up the development of cancer cells! If there are 8 signs, it's time to reduce stress

A. Too much stress will accelerate the development and spread of cancer cells

During cancer treatment, doctors often emphasize optimism and instruct patients to take it easy and reduce stress. Can stress really have an effect on the disease? A study has given the answer.

Modern medicine believes that psychological stress is one of the risk factors for about 90% of human diseases. A number of studies have also been conducted to study this in depth, and it has been theorized that "psychological stress may cause certain hormones to kill immune cells.

On April 13, 2021, Cell Reports, a subissue of the leading medical journal CELL), published a study completed by researchers at Westhampton University in Canada.

It's been proven: too much stress may speed up the development of cancer cells! If there are 8 signs, it's time to reduce stress

The study observed in a mouse model that stress-induced hormones, glucocorticoids, substantially impair the function of innate T cells and weaken the immune system's defense against disease and tumors, thereby increasing the risk of cancer development, progression and spread.

Extra Lesson Tip: T cells are a cell type in the immune system that has antigenic immunity, while innate T cells are T cells that are in a pre-activated state and are able to respond to pathogens or cancer cells in an emergency.

Second, long-term stress, but also may cause 6 major problems

Some people think that stress is just a psychological problem, hold on, endure a little and pass, do not know, too much stress can also be accompanied by somatization symptoms, such as drowsiness, headache, easy to forget things, rash, acne, muscle and joint discomfort, gastrointestinal discomfort, high blood pressure ...... above symptoms may be accompanied by stress for a long time, will undoubtedly affect the normal conduct of work life.

In addition, long-term high-pressure state, the human immune system is damaged, continued decline, not only may induce cancer, but also easy to provoke 6 major health problems, worthy of attention!

1、White head overnight

When the body's hair or hairs are newborn, melanocyte stem cells are differentiated to produce melanocytes, which synthesize pigment to color the hair.

The vicinity of the hair or hair-dependent follicles is mainly innervated by sympathetic nerve cells. When the body is stressed, sympathetic nerve cells are stimulated to secrete large amounts of norepinephrine (mainly secreted by the sympathetic and adrenal glands), and this hormone stimulates melanocyte stem cells to become overactive or even depleted, resulting in insufficient sources of melanocytes and no source of coloring for the hair, which naturally becomes lighter and whiter.

2、Hair loss

There are many types of hair loss, and many people only focus on androgenic baldness and baldness, but in fact the most common clinical case of hair loss is resting alopecia.

Yang Shuxia, chief physician of the Department of Dermatology at Peking University First Hospital, introduces: resting hair loss, which refers to the advancement of a large number of hairs from the growth phase to the resting phase under the influence of multiple emergency factors, thus causing hair loss symptoms. The so-called multiple contingency factors refer to long-term excessive stress or factors related to it such as anxiety and depression.

Reminder: There is a delay in resting hair loss, which is usually exposed 3 months after the triggering factor.

3, increase the risk of osteoporosis in menopausal women

The medical journal Journal of Epidemiology and Community Health published a study completed by researchers at the University of Arizona that looked at aspects and information on social support, social stress and social functioning, as well as physical data related to bone density, in 11,000 menopausal women.

A comprehensive comparative analysis revealed that the higher the social stress, the higher the risk of decreasing bone density in the lumbar spine, total hip, and femoral neck of menopausal women. Among them, social function may increase the risk of osteoporosis in the femoral neck and total hip joint.

Researchers say that the underlying cause of changes in bone density may be due to changes in hormone levels such as growth hormone, thyroid hormone, cortisol, and glucocorticoids.

4、Damage to the brain

The international journal Autophagy has published a study completed by Daegu Kyungpang Institute of Science and Technology, which confirmed that chronic stress increases autophagic death of adult hippocampal neural stem cells (NSCs), thereby damaging the brain, although the exact molecular pathological mechanism is unclear.

In addition, a study published in the international journal Biological Psychiatry by scientists from King's College London also pointed out that the stress suffered by women during pregnancy can have a negative impact on the development of the fetus' brain.

5, induced heart attack and sudden cardiac death

A study in the Journal of the American Medical Association (JAMA) found that 16% of the 918 patients with stable coronary artery disease who participated in the study had episodes of myocardial ischemia related to stress, 31% had myocardial ischemia related to conventional stress, and the remaining 10% had both conventional stress and stress characteristics. Also during the subsequent 5-year follow-up, there were 319 heart failure hospitalizations and 156 infarction deaths or cardiovascular disease deaths.

Studies have proven that the main risk factor for heart attack and sudden cardiac death in susceptible populations is mental stress.

6、Reduces immune function

The American medical journal Immunity published a study led by Scott Muller, a professor at the University of Melbourne in Australia, which found in experiments with mice that the nervous system in a stressed state showed inhibitory signals of immune cell activity that prevented them from making defenses against disease.

Third, there is a kind of pressure is actually good for the body

Long-term chronic stress naturally does more harm than good to the human body, but not all stress is bad, there are studies have found that there is a kind of stress may have some benefit to the human body.

In 2018, a Dutch study was published in the medical journal BMC Medicine, which found that multiple weekly saunas reduced the risk of cardiovascular-related death in long-term follow-up data from a frontier cohort, and that saunas can be considered a short-lived heat stress.

In 2018, a similar study in the medical journal Neurology (Neurology) confirmed the ability of sauna to reduce the risk of ischemic stroke. Some experts suggest that this may short time heat stress reduces oxidative stress, inflammation and other negative conditions in the body.

The above findings may indicate that when the body experiences acute physiological stress for a short period of time, it is possible that a degree of benefit can be obtained.

Fourth, how to effectively relieve stress?

In any case, the threat of long-term chronic stress on the human body still exists, and more and more people are now focusing on how to solve the problem of stress, 4 simple and easy to do methods or effective stress relief!

1、Keep high quality sleep

Nature Human Behaviour, a subjournal of Nature, published in 2019 a study from the University of California, Berkeley, which confirms that good deep sleep helps the brain to reshape the links between different areas and largely assists in stabilizing mood and relieving anxiety, while in contrast sleep deprivation increases the risk of negative mood by 30%.

2、Rational exercise

In a series of studies, a team at Massachusetts General Hospital at Harvard Medical School found that exercise reduces stress-related neural activity. The study confirmed that moderate intensity activity of 150 minutes or more per week reduced the risk of major adverse coronary cardiovascular disease by 16 percent. Highlights: This data was particularly strong in depressed and anxious populations.

3、Eat more fruits and vegetables

A new study published in Clinical Nutrition by a team of researchers from Edith Cowan University in Australia found that people who consumed more than 470 grams of vegetables and fruits per day were 10% less stressed than those who consumed less than 230 grams. The study confirms that increased intake of vegetables and fruits can reduce psychological stress.

Simon Radhavali Bagatini of the Institute of Nutrition at Edith Cowan University said that vegetables and fruits are rich in minerals, vitamins and other nutrients that improve oxidative stress and inflammatory responses in the body and may be the main cause of stress relief.

4、Frequent contact with nature

Numerous medical studies have found that a green space environment will have some effect on the inflammatory response in the human body, thus achieving the effect of stress relief. Therefore, it is recommended that we do more outdoor activities on a daily basis and often go to a green environment with more plants.

It's been proven: too much stress may speed up the development of cancer cells! If there are 8 signs, it's time to reduce stress

Of course, more than the above four ways to relieve stress, there are positive thinking exercises, confide in a friend, seek help from a psychiatrist, stress relief games, etc. are very good help to relieve pressure. With the accelerated pace of society, stress is a common problem faced by contemporary people. I hope we can learn to face stress squarely, make appropriate moves against it and eliminate the risk of stress in time. #Rumor Zero Project #Head Weekly
