Working the night shift may cause dangerous health conditions, long-term risk of disease

Working through the night can put a toll on your body and overall health. 

More than 9 million adults in the United States work shifts at night, according to the U.S. Census Bureau.  

There are many jobs in a variety of industries that require staff at night, including medical professionals, flight attendants, hotel receptionists, construction workers, truck drivers, firefighters, law enforcement and others. 

CANCER TRENDS REVEALED, INCLUDING MOST COMMON TYPES OF THE DISEASE AND BIGGEST RISK FACTORS

Working the night shift requires adjusted sleep schedules and meal times, which are two contributing factors to the health problems associated with late-night hours that could include an increased risk of cancer, gastrointestinal disorders and more.

  3. Increased risk for cardiovascular disease

1. Increased cancer risk

Studies have shown an increased risk of certain cancers among those who work the night shift.

The National Toxicology Program (NTP) drew its own conclusions based on “systematic review methods and established criteria” about a link between working the night shift to certain cancers, according to a 2021 report by the organization. 

Studies have shown several different health risks linked to frequently working the night shift for extended lengths of time.  (iStock)

The NTP found “high evidence” that frequently working the night shift disrupts circadian rhythms and can cause breast cancer in women and prostate cancer in men. 

A circadian rhythm is the body’s internal 24-hour clock. One factor that affects a circadian rhythm is light.

Working the night shift disrupts the body’s circadian rhythm because a person is working during a time when the body’s natural instinct is to sleep. 

If you are someone who often works the night shift, the Centers for Disease Control and Prevention (CDC) recommends trying to stick to a similar sleep schedule even on the days when you are off from work to help your body get into a better routine.

2. Possible gastrointestinal disorders

When you work the night shift, you may eat at odd hours. 

Possible gastrointestinal disorders you could face include abdominal pain, gas, diarrhea, constipation, nausea, vomiting, change in appetite, indigestion and heartburn, according to The National Institute for Occupational Safety and Health (NIOSH).

A disturbed circadian rhythm can again be to blame for these gastrointestinal problems because the body’s internal clock may not properly function when food is eaten at abnormal hours during the night. 

HERE’S WHY YOU’RE BLOATED – AND WHAT TO DO ABOUT THE COMMON DIGESTIVE CONDITION

It is important to keep yourself fueled with food and hydrated with plenty of water while you’re on your feet working long hours at night. 

What you eat at work, and even where you eat, can help ease these digestive problems, according to NIOSH. 

Recommended foods for work hours include vegetables, salads, soups, fruits, wholegrain sandwiches, yogurt, cheese, eggs, nuts and green tea.

The NIOSH also suggests seeking a different environment to eat away from work and try to enjoy your meal with other coworkers. 

Avoid eating between midnight and 6 a.m. if possible to help form a relatively normal meal routine, NIOSH recommends.

3. Increased risk for cardiovascular disease

Heart health could be a risk from many years of frequent night shifts. 

Research has made a connection between certain risk factors that could be prevalent in those who work the night shift that are associated with cardiovascular disease, such as smoking and metabolic disturbances, according to NIOSH.

Those with high blood pressure could be at a higher risk of developing cardiovascular disease and diabetes if they work frequent night shifts, according to findings published in August 2022 by the Journal of the American Heart Association.

The study spanned over 12 years, in which 36,939 participants in the U.K. Biobank were monitored. 

It was found that those who had high blood pressure and worked night shifts had a 16% higher risk of developing heart disease, diabetes and stroke than those who worked during normal daytime hours, according to the study.

4. Psychological concerns

Working the night shift can come with many psychological concerns.

Individuals who frequently work during the night can experience extreme fatigue and feelings of isolation. 

One mental health concern prevalent for those who work the night shift is depression.

In 2023, a study was published in the National Library of Medicine backing this concern. 

A systematic review and meta-analysis was done to determine whether there was a link between depression and nurses working night shifts. 

 

The study found “a significant association between night shift work, the circadian and sleep disruption it causes and the risk of depression in nurses.”

One walking habit could signal a healthier brain after 80, scientists say

One walking habit could signal a healthier brain after 80, scientists say

NEWYou can now listen to Fox News articles!

Older adults identified as “super movers” are about half as likely to develop cognitive impairment than their peers.

That’s according to a recent study led by Stony Brook Medicine in New York, which evaluated the cognitive function of 4,000 adults 80 and over who participated in multiple aging and longevity studies over several years.

Among this group, 6% to 10% were classified as super movers, which means they walk at a much faster pace than others of the same age and gender — at speeds comparable to people three decades younger.

The super movers were found to have about half the risk of cognitive decline compared to seniors with typical gait speed.

The findings were published in the journal Neurology on June 16.

“The study reinforces that mobility and brain health are closely connected,” lead study author Dr. Joe Verghese, MD, neurologist at Stony Brook Medicine, told Fox News Digital. “This suggests that preserving mobility may be an important marker of healthy brain aging and resilience.”

The most intriguing finding, according to Verghese, was that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.

In postmortem brain analysis, there was no difference in dementia-related pathologies between the super movers and the slower walkers, the study stated.

“This suggests they may possess resilience mechanisms that help preserve brain function even in the presence of age-related changes,” he said. “Understanding these resilience factors could lead to new strategies for promoting healthy brain aging.”

As the study was observational, there were some limitations, and it does not prove that walking faster prevents dementia, the researchers noted.

“Other factors, such as cardiovascular health, physical fitness or genetics, may also contribute to both faster walking and better cognitive outcomes,” Verghese said.

This study adds to growing evidence that what’s good for the heart and muscles also benefits the brain, he noted, adding that “staying physically active remains one of the most effective, evidence-based ways to support healthy aging.”

“Walking speed is best viewed as a marker of overall health, not a treatment.”

“The broader message is that physical activity is important at any age,” Verghese said. “Walking is an easy step-up point because you don’t need any special equipment. You can do it inside or outdoors, and you can do it on a regular basis. You can walk with a dog, you can walk with a friend.”

Any activity is beneficial if it’s done regularly and with the right intensity, he added.

Rather than just trying to walk faster, the neurologist recommends that seniors focus on maintaining mobility through regular physical activity, strength training, balance exercises and good cardiovascular health.

“Walking speed is best viewed as a marker of overall health, not a treatment,” Verghese noted.

Major public health guidelines from the CDC and U.S. Physical Activity Guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.

This can be achieved by walking 30 minutes a day, five days a week, or about 20 to 25 minutes most days. Another option is to engage in shorter sessions that add up over the day.

“You have to do it within your health limitations and medical conditions,” Verghese advised. “So if there are any medical concerns, I would get your physician to clear you before starting exercise.” The good thing about walking, he added, is that you can start at a slow pace and then gradually build up to a brisker pace.

“And then adding on strength and balance training, whatever age you are, I think is also important.”

Dr Oz warns Medicare scammers are stealing billions — and your personal information could be next

NEWYou can now listen to Fox News articles!

Medicare fraud is a multibillion-dollar problem that government officials say threatens both taxpayer dollars and Americans’ personal identities.

In a July 6 interview with Fox News Digital at the Great American State Fair in Washington, D.C., Dr. Mehmet Oz warned that every dollar stolen through Medicare fraud is a dollar taxpayers lose – a problem that has worsened since the COVID pandemic.

“If I had to just pick one thing to focus on to make healthcare more affordable in America, I’d go to health fraud and all the waste and abuse that accompanies it,” said Oz, who is the administrator of the Centers for Medicare & Medicaid Services. “And just to put this in perspective, we think it’s about $100 billion a year.”

Medicare fraud can include billing for services that were never provided, overcharging for medical equipment, using stolen patient or doctor information, or performing unnecessary procedures, according to the U.S. Government Accountability Office.

As the Trump administration ramped up efforts to combat fraud, CMS reported $41.9 billion in Medicare program integrity savings in 2025, up 59% from $26.3 billion in 2024.

Medicare fraud not only harms the federal budget and steals from taxpayers, but exposes seniors to identity theft, unnecessary care, higher premiums and reduced access, Oz cautioned.

Removing corruption from the healthcare system will have the greatest impact among seniors, since “so much of the fraud is perpetrated against them,” the administrator said.

“I’m talking about people tricking seniors to give up their Medicare beneficiary numbers, which is like a credit card basically,” he said. “These scammers can take those numbers and use them for all kinds of illegitimate purposes.”

“People are stealing from you by pretending to send you drugs you don’t want, wheelchairs you don’t need, [and] services you never asked for or don’t benefit from,” Oz added.

To prevent this, he shared his top advice for seniors: Do not give your Medicare beneficiary number to anybody, do not answer questions on a phone call from an unknown person and do not give away personal information.

“These scammers are calling seniors, tricking them, and once they have key information, they can steal it,” he said. “And I won’t know it and you won’t know it.”

“We want to protect people who need these programs the most,” Oz went on. “You do that by making sure scoundrels don’t corrupt the systems and steal money out of the till that is designed to help folks in dire straits when they’re vulnerable and in need of services.”

Seniors should never share their Medicare information with unknown people, the administrator advised. (iStock)

Removing fraud could “double the life expectancy of the trust fund that makes all this possible,” Oz predicted.

“If you’re worried about Medicare being there when you’re ready to retire in a couple decades, depending on how old you are, and you’re concerned that it might not last because of all the fraud that’s hitting it … you’ve got a good [reason to] worry,” he said.

“If we take the fraud out, we could double the life expectancy, which means you, your kids, your kids’ kids … they could all benefit from this beautiful safety net program.”
