Cigarettes with a low tar content are not a safer option.

No comments

 According to studies, smoking cigarettes with a high tar content, as compared to cigarettes with a medium tar content, significantly increases your risk of lung cancer. Therefore, cigarettes branded as low-tar or ultra-light are a safer bet, correct? Wrong. This apparently obvious assumption is untrue, according to research comparing the lung cancer risks of various kinds of cigarettes.

The research lasted six years and enrolled over 900,000 adults in the United States over the age of 30. The researchers examined the risk of lung cancer death in men and women who were current or past smokers or who had never smoked. When the study's findings were examined according to the tar rating of the cigarettes smoked, it was shown that the risk of lung cancer death was greatest for smokers of unfiltered cigarettes with a high tar content. There was no difference in the risk of lung cancer death among smokers of medium-, low-, and very low-tar cigarettes.

Even in moderation, alcohol can cause harm to your brain.

This research is still being monitored

Even moderate drinking may be detrimental to your brain, according to research published online by The BMJ on June 6, 2017. Researchers from the University of Oxford and University College London discovered that imbibers, even those who matched standards for moderate drinking, experienced a greater rate of cognitive loss and brain shrinkage than teetotalers.

The study tracked 550 men and women for 30 years, evaluating their brain structure and function to ascertain the long-term effects of alcohol usage on the mind. They discovered that the more people drank, the more atrophy happened in the hippocampus, a seahorse-shaped region in the brain involved in memory storage. Individuals who consumed 17 standard drinks or more of alcohol per week had the greatest risk. However, even moderate drinkers had an increased risk of cognitive impairments.

The facts about sex and testosterone

No comments

Testosterone is a hormone that plays an essential part in men's health, but its primary purpose is to enhance sex drive and performance.

Testosterone levels tend to drop as people become older. They reach a peak in early adulthood and then begin to decline at a rate of up to 1% each year around the age of 40. An injury or disease (such as an infection), chemotherapy or radiation treatment, or some medicines can induce a sudden fall.

Men might suffer from a weak libido and erectile dysfunction when testosterone levels drop too low. Low levels can also lead to tiredness, mood swings, loss of muscular mass, and bone strength.

Most men can maintain sufficient testosterone levels long into their late adulthood. Maintaining good health might also assist to slow down the ageing process. Many older men, however, consider testosterone replacement treatment (TRT) as a way to replenish decreased levels. It's reasonable to believe that TRT might make a man feel younger and give his sex life more physical strength and good health.

Plant protein may help you in living a longer life.

Protein is necessary for men to maintain muscle mass and strength as they age. According to research published online by JAMA Internal Medicine on July 13, 2020, the source of that protein may also influence how long people live. Scientists studied the diets of almost 400,000 people aged 50 and over who ate plant-based protein, red meat, and eggs. After then, they were tracked for more than 16 years. People who ate primarily plant protein rather than red meat or egg protein had a 13 per cent to 24 per cent decreased chance of dying from any cause.

Can urinary tract infections be prevented?

Can we prevent urinary tract infections?

If you've never had a urinary tract infection (UTI), take note: while the illnesses are uncommon in older males, they are frequent in older women, occurring in 10% of women aged 65 to 85. Up to a third of women who get a UTI will experience a recurrence within six months.

"E. coli bacteria which live in the intestines are responsible for roughly 80% of all recurrent UTIs and continue to generate antibiotic-resistant germ strains. The bacteria' ability to adhere to the urinary tract can make them extremely difficult to eliminate.

The causes of urinary tract infections

UTIs can develop in any part of the urinary system, including the kidneys, bladder, ureters (the tubes that carry urine from the kidneys to the bladder), or urethra (the tube that carries urine out of the body).

Female anatomy — especially, the short urethra that opens to the outer world just above the vagina — has an effect on women's susceptibility. This is because germs from the rectum, particularly E. coli (officially known as Escherichia coli), can be pushed into the urethra opening by wiping or sexual intercourse. They can then ascend the urethra to the bladder.

"Because males have a larger urethra, they seldom acquire UTIs,"  "However, occasionally, a man's enlarged prostate gland obstructs the passage of urine from the bladder, resulting in urine pooling and providing a breeding ground for germs.

How to Reduce the Harmful Effects of Air Pollution on Your Health

No comments

What is pollution?

Pollution is defined as anything that is introduced into the environment by humans that damages human health or ecosystems. There are different types of pollutions and they all affect human health. Air pollution, water pollution and soil pollution. These forms of pollution happen by the use of heavy metals, chemicals, gasses, germs, and even noise.

The combustion of fossil fuels (coal, gas, and oil), as well as wildfires, contribute to outdoor air pollution. These produce toxic fumes, smog (due to ground-level ozone), and soot (fine particles) that are dangerous to inhale. Fireplaces and home cookstoves that utilize gas, coal, or biomass fuels like wood or agricultural waste, which are sometimes used in low-income countries, are among the sources of indoor air pollution.

Since the passage of the Clean Air Act in 1970, air pollution in the United States has significantly decreased. However, certain air pollutant levels have risen in recent years, and air pollution continues to have severe national and global health impacts.

Different studies over the years have frequently repeatedly shown that increased outdoor air levels of fine particulate matter correspond to increased hospitalizations for chronic obstructive pulmonary disease exacerbation, stroke, diabetes, heart disease, pneumonia and other severe health issues. Whether it is a long term exposure or short-term exposure, they are all effective.

What is the impact of air pollution on your health?

This year, a study looked at worldwide models of pollution levels and risk assessments of the global population over the course of 14 years. It links fossil fuel consumption to over nine million premature deaths worldwide in 2018 — one in every five fatalities — with over 350,000 deaths in the United States. Heart attacks and strokes account for the majority of these fatalities.

What is the endocannabinoid system (ECS)?

No comments

Many of us have heard about some of our bodies' transmitter systems, such as the sympathetic nervous system, which controls our fight-or-flight response. Fewer people are familiar with the more recently discovered endocannabinoid system (ECS), which is remarkable given that the ECS is essential for nearly every element of our day-to-day functioning. The endocannabinoid system regulates and controls many of the critical body functions which include memory, emotional processing, temperature control, inflammatory control, immune responses, eating, learning, pain control and even sleep. The ECS is at the forefront of innovative worldwide research and medication development. The endocannabinoid system is currently at the centre of renewed international research and drug development.

What is the endocannabinoid system (ECS)?

The ECS comprises a vast network of chemical signals and cellular receptors that are densely packed throughout our brains and bodies. The brain's "cannabinoid" receptors – the CB1 receptors - outnumber several other receptors in the brain. They function similarly to traffic cops, regulating the amounts and activity of most of the other neurotransmitters. They regulate things by increasing or decreasing the activity of the system that requires adjustment, immediate feedback, hunger response, alertness or temperature.

Our bodies generate chemicals called endocannabinoids that stimulate these receptors which have a structural similarity to the molecules found in the cannabis plant also known as hemp. The very first endocannabinoid that was discovered was called Anandamide which is named after the Sanskrit word ananda for bliss. Anandamide is a lipid mediator that acts as an endogenous ligand of CB1 receptors. These receptors are also the primary molecular target that is responsible for the pharmacological effects of Δ9-tetrahydrocannabinol. The psychoactive ingredient in Cannabis sativa is Δ9-tetrahydrocannabinol. Each of us has tiny cannabis-like molecules floating around in our brains. Humans have been using cannabis for almost 5,000 years, and it effectively works by hijacking this ancient cellular machinery.

The second type of cannabinoid receptor, the CB2 receptor, exists mostly in our immune tissues and is critical to helping our immune functions and control and it plays a role in modulating contraction, intestinal inflammation and pain in inflammatory intestinal bowel conditions. CB2 receptors are particular targets of drug development because they don’t cause the high (stoned) associated with cannabis that stimulating the CB1 receptors does.

New treatment for pericarditis approved

No comments

This is an ongoing research

An infection, heart surgery, or unknown causes might cause the pericardium (the lining surrounding the heart) to become irritated. Pericarditis is a type of irritation that causes acute, stabbing pain in the centre of the chest. Although it normally goes away after four to six weeks, some people have many attacks.

Menstrual periods that are irregular and long are connected to a shortened lifespan.

Is it possible to predict your longevity based on your current or previous menstrual cycle? A study published in The BMJ on Oct. 3, 2020, linked irregular or menstrual periods that are long (defined as 40 days or more) both in adolescence and adulthood to a higher risk of early death (before age 70) than those with normal or short menstrual cycles. The researchers discovered that the link was stronger for fatalities from heart and blood vessel disease and among women who smoked, based on data from roughly 80,000 women who took part in the Nurses' Health Study II.

Cancer treatment may be aided by gut microorganisms. This research is still ongoing and being watched.

Researchers at the National Cancer Institute's Center for Cancer Research discovered that changing the type of microbes in the gut helped people with metastatic melanoma (a type of skin cancer that is aggressive) react to immunotherapy treatments that had previously failed them.

Is getting more sleep going to help me avoid dementia?

No comments

Will sleeping for extended periods protect you from dementia? Is this a true statement?

According to several published research, persons who sleep fewer than seven hours or more than nine hours a night are more prone to acquire different chronic illnesses, including dementia, than those who sleep seven to nine hours. These studies, on the other hand, have flaws. Some did not have a large number of patients. Others focused on how long people slept when they were 65 years old, rather than how long they slept when they were younger. Other trials lasted just around ten years, making it difficult to make any conclusions regarding long-term health impacts. Finally, the majority of research just accepted the individuals' claims regarding how long they slept. We also tend to lie a little when we report on our healthy living routines.

So, while I was inclined to believe that getting enough sleep was crucial for one's health and may even guard against dementia, I wasn't persuaded. However, recent research published in the journal Nature Communications on April 20, 2021, has gone a long way toward persuading me. 8,000 50-year-olds were chosen and tracked for 25 years by researchers. Participants in the research kept track of how long they slept each night, and some even wore gadgets that tracked their body movement, ensuring that their sleep reports were reliable. To put it another way, the study overcomes many of the flaws of previous research.

The study's findings were shocking. When people aged 50 slept an average of seven hours per night compared to those who slept just six hours per night, it was shown that those who slept less were 22 per cent more likely to acquire dementia. When adults aged 60 were compared, those who slept less were found to be 37% more likely to acquire dementia. The odds of acquiring dementia were considerably higher for those who slept less than six hours every night – people like you.
