1. Use silk pillowcases
Swapping cotton pillowcases for a silk material could help with beauty sleep in more ways than one, according to experts.
Over time, this habit can “keep the skin looking young and the hair lustrous and silky,” Skydan shared in an email message.

“There is no evidence that sleeping on a silk pillowcase minimizes acne breakouts, minimizes the formation of facial wrinkles or prevents split ends or chemical exposure,” she said via email.
“Don’t expect healthier skin or hair from making such a purchase.”
2. Try petroleum jelly before applying perfume
To help extend the longevity of perfume or cologne, Skydan suggested applying petroleum jelly to the skin prior to application.

“Apply a small amount of [petroleum jelly] behind your ears, wrists and neck, then spritz perfume over them,” she said.
“Viola! Your perfume will linger both in the morning and evening.”
3. Wash underarms and feet with benzoyl peroxide, but take extra care if doing so
To decrease surface bacteria and minimize body odor, Frey suggested washing the underarms and feet with benzoyl peroxide.
She did advise users to be careful when applying the product, however, as it can sometimes cause irritation and redness and could remove color from clothes.
Using benzoyl peroxide could help with reducing body odor in the warm, sweaty summer months, an expert advised, with some caveats. (iStock)
To help minimize side effects, Skydan also recommended checking the usage instructions on the benzoyl peroxide packaging.
For those who can’t tolerate the product, a mild cleanser is a good alternative, Frey said.
4. Use antiperspirant wipes for long-lasting protection
Using antiperspirant wipes could help maintain dryness for those who tend to sweat excessively, Skydan recommended.

Antiperspirant protects against sweat and odor, while a typical deodorant only prevents odor, according to Dove.

Antiperspirant wipes should be used at night once a week to “keep you dry for up to seven days,” Skydan said.
She added, “If you’re a heavy sweater, antiperspirant wipes should be in your arsenal.”
5. Know when to exfoliate your skin
“Exfoliate, exfoliate, exfoliate” seems to be a common tip given by dermatologists and skin experts.
“Regular exfoliation keeps your skin healthy, smooth and fresh by removing dead skin cells and stimulating new cell growth,” Skydan told Fox News Digital.

Frey, however, only recommends exfoliating for the purpose of removing dead cells, dirt and oil — and says to do so with caution, noting that it can be difficult to measure the positive effects.
“Measuring cell turnover is a very difficult, time-consuming and expensive metric to accurately measure,” she said.
“If you have healthy skin, forget the exfoliants and scrubs.”

An accidental lab discovery has opened the door to entirely new ways of preventing the flu.
While investigating how influenza replicates, researchers discovered that different flu strains use completely different strategies to infiltrate human cells, SWNS reported.
By targeting the specific molecules the viruses rely on, scientists found that they could block them from entering new cells and halt their replication altogether.
5 THINGS YOU NEED TO KNOW BEFORE GETTING YOUR FLU SHOT, ACCORDING TO DOCTORS
Researchers say these “fundamental insights” into seasonal influenza highlight a clear path toward developing better preventive medications.
“The hope is that fundamental, curiosity-based research like this helps to pave the way for novel strategies to treat and prevent influenza infections,” principal investigator Dr. Emily Bruce, from the University of Vermont’s Larner College of Medicine, said in the SWNS report.

While several flu strains cause illness, H1N1 and H3N2 influenza A viruses are the most common. However, current flu tests cannot differentiate between them, and clinical treatments are identical for both.
Although vaccines and antivirals are available, Bruce noted a “dire” need for better medications to stop the virus from spreading cell to xxcell.
“You don’t get sick when a virus is in one cell,” he noted. “You get sick because a virus replicates itself and goes into many more cells.”
HOW LONG YOU’RE CONTAGIOUS WITH THE FLU — AND WHEN IT’S SAFE TO GO OUT
The study, which was published in The Journal of Virology, originally aimed to map how viral RNA segments are transported within cells to create new viral particles.
The team used H1N1 and H3N2 viruses isolated from the nasal passages of positive patients in 2022.

During the investigation, the team unexpectedly stumbled upon a cellular pathway that blocked the virus from entering lung cells, SWNS reported.

The data revealed that when a specific human protein called Rab11B was depleted, H3N2 viruses failed to enter human lung cells. H1N1 viruses were completely unaffected.
Using reverse genetics, the team mapped this defect and uncovered a brand-new, H3N2-specific role for Rab11B during viral entry.

“Viruses are like pirates from different countries hijacking someone’s ship,” Bruce said. “Different viruses, like different types of pirates, use different methods to get onboard.”
This discovery challenged the scientific assumption that all flu viruses enter cells the same way. (iStock)
“We had previously thought that all flu viruses used the same way to get into a cell, but we discovered that this is not true,” she went on. “H1N1 and H3N2 need different proteins to get in, and if you get rid of the right protein, a specific virus can’t get in.”

While these findings identify a critical cellular pathway for viral entry, the study was conducted using isolated cells, the researchers acknowledged.

Further research is needed to determine whether blocking the protein is safe and effective within a live, complex human respiratory system.
Bruce and the team hope to conduct further research to determine whether this Rab11B-dependency is a fundamental property of H3N2, or if it’s a trait unique to currently circulating flu strains.

Eating processed meat like ham, sausage and bacon may be linked to a higher risk of certain types of cancer, according to new research.
While health organizations have already confirmed that processed meat can contribute to colon cancer, this study looked closer at cancers in the upper digestive tract, where the link has historically been less clear.
To understand these connections, researchers from the European Prospective Investigation into Cancer and Nutrition (EPIC), one of the world’s largest long-term nutrition and cancer cohorts, tracked the health and diets of 450,112 people across Europe for an average of 14 years.

The study group included 131,426 men and 318,686 women, according to the study’s press release.
During the follow-up period, 876 people developed stomach cancer and 215 people developed esophageal adenocarcinoma, which is cancer of the tube connecting the mouth to the stomach.
For female participants, eating both processed meat and white meat was linked to an increased risk of developing the disease. (iStock)
Researchers tracked where the stomach cancers grew, separating them into the upper part of the stomach near the throat and the lower part of the stomach.
The researchers also sorted the tumors into two categories based on how the cancer cells appeared under a microscope: intestinal, which forms more organized structures, and diffuse, in which the cells are more scattered throughout the tissue.
BACTERIA IN YOUR MOUTH MAY TRAVEL TO THE GUT AND TRIGGER STOMACH CANCER, RESEARCH FINDS
After adjusting for other lifestyle factors, the researchers found that for every extra 30 grams of processed meat a person ate per day, their overall risk of stomach cancer went up by 9%. Eating that same extra 30 grams a day was also linked to a 13% higher risk of esophageal adenocarcinoma.
A standard single slice of regular deli-sliced ham or lunch meat averages around 28 grams, according to USDA data and nutritional tracking databases.
An extra 20 grams of white meat, such as chicken and turkey, was linked to a 12% higher risk of cancer in the main body of the stomach. (iStock)
An extra 20 grams of white meat, such as chicken or turkey, was linked to a 12% higher risk of cancer in the main body of the stomach, the researchers noted.
The study also revealed differences between men and women. For male participants, only processed meat showed a clear, statistically significant link to a higher risk of stomach cancer. For female participants, however, eating both processed meat and white meat was linked to an increased risk.

These findings align with global health benchmarks, particularly those established by the World Health Organization’s International Agency for Research on Cancer.
The agency has long classified processed meat as a known human carcinogen, primarily due to its strong, well-documented links to colorectal cancer.

However, health organizations have also consistently pointed to a potential, yet less definitive, relationship between these meats and cancers of the stomach.
Eating 30 grams of processed meat a day, or the equivalent to one slice of ham, was linked to a 13% higher risk of esophageal adenocarcinoma. (iStock)
Further scientific investigation is needed to confirm the findings and to account for other underlying risk factors, such as certain stomach infections, which could interact with dietary habits.

A key limitation of the study is its reliance on self-reported diets, which can sometimes lead to inaccuracies in how participants recall their meat consumption over time, the researchers noted.
