'Napuccino' trend: Caffeine before a nap could be key to better sleep

Caffeine and sleep may seem like polar opposites — but there may be a benefit to combining them.

The “napuccino” has become a popular method to optimize sleep and wake up with more energy by drinking a caffeinated beverage before lying down for a nap.

In a recent episode of the podcast “The Diary of a CEO” with Steven Bartlett, sleep expert Dr. Cheri Mah in Redwood City, California, introduced the napuccino as a “useful tool if you’re trying to have a temperate boost in alertness and performance.”

A napuccino requires drinking a caffeinated beverage of choice before taking a 20- to 30-minute power nap, according to Mah.

The caffeine will begin to kick in 15 minutes after consuming it.

“If you’re able to fall asleep within five to 10 minutes while the caffeine will start to come on board, then when you wake up after 20 to 30 minutes … the caffeine will have kicked in,” she said.

Research has shown that the energy from both the caffeine and the power nap is “more effective for alertness and performance improvement for a couple of hours,” compared to only drinking caffeine or napping alone, Mah said.

Fox News Digital reached out to Mah for further comment.

“By the time you get up from the nap (20 to 30 minutes), the caffeine is kicking in.”

Clinical psychologist Kelly Baron, PhD, director of the behavioral sleep medicine lab at the University of Utah, described the napuccino as a “really great and scientifically tested technique.”

“Having some caffeine, plus a short nap, is better than either one of those alone,” she told Fox News Digital.

This method has been tested with certain activities, such as driving performance and shift work, Baron noted.

“Short naps with or without caffeine are proven techniques to boost performance for those experiencing sleepiness,” she said.

Getting the standard seven to nine hours of sleep per night is ideal, the expert said, but that can be challenging for some people.

“Drinking coffee with a lot of added sugar or high-calorie creamers can offset some of the potential health benefits,” one expert warned. (iStock)

Los Angeles-based registered dietitian and nutritionist Ilana Muhlstein agreed that the napuccino can be a “great strategy to boost alertness,” but also noted it’s important to consider how people prepare their coffee.

“Drinking coffee with a lot of added sugar or high-calorie creamers can offset some of the potential health benefits,” she said.

“Consuming too much sugar can lead to energy spikes and crashes, which might counteract the energizing effect of the nap and caffeine.”

Muhlstein suggested drinking black coffee, or with a splash of regular or plant-based milk, zero-calorie sweetener like Stevia, or monk fruit.

“This way, you’re reaping the benefits of the napuccino without the drawbacks of excess sugar or calories,” she said.

Up to 400 milligrams of daily caffeine is deemed safe for most healthy adults, according to Mayo Clinic.

Heart disease threat projected to climb sharply for key demographic

NEWYou can now listen to Fox News articles!

A new report by the American Heart Association (AHA) included some troubling predictions for the future of women’s health.

The forecast, published in the journal Circulation on Wednesday, projected increases in various comorbidities in American females by 2050.

More than 59% of women were predicted to have high blood pressure, up from less than 49% currently.

The review also projected that more than 25% of women will have diabetes, compared to about 15% today, and more than 61% will have obesity, compared to 44% currently.

As a result of these risk factors, the prevalence of cardiovascular disease and stroke is expected to rise to 14.4% from 10.7%.

Not all trends were negative, as unhealthy cholesterol prevalence is expected to drop to about 22% from more than 42% today, the report stated.

Dr. Elizabeth Klodas, a cardiologist and founder of Step One Foods in Minnesota, commented on these “jarring findings.”

“The fact that on our current trajectory, cardiometabolic disease is projected to explode in women within one generation should be a huge wake-up call,” she told Fox News Digital.

NEARLY 90% OF AMERICANS AT RISK OF SILENT DISEASE — HERE’S WHAT TO KNOW

“Hypertension, diabetes, obesity — these are all major risk factors for heart disease, and we are already seeing what those risks are driving. Heart disease is the No. 1 killer of women, eclipsing all other causes of death, including breast cancer.”

Klodas warned that heart disease starts early, progresses “stealthily,” and can present “out of the blue in devastating ways.”

The AHA published another study on Thursday revealing one million hospitalizations, showing that heart attack deaths are climbing among adults below the age of 55.

The more alarming finding, according to Klodas, is that young women were found more likely to die after their first heart attack than men of the same age.

“This is all especially tragic since heart disease is almost entirely preventable,” she said. “The earlier you start, the better.”

Children can show early evidence of plaque deposition in their arteries, which can be reversed through lifestyle changes if “undertaken early enough and aggressively enough,” according to the expert.

Klodas suggested that rising heart conditions are associated with traditional risk factors, like smoking, high blood pressure, high cholesterol, diabetes, obesity and a sedentary lifestyle.

Doctors are also seeing higher rates of preeclampsia, or high blood pressure during pregnancy, as well as gestational diabetes. Klodas noted that these are sex-specific risk factors that don’t typically contribute to complications until after menopause.

The best way to protect a healthy heart is to “do the basics,” Klodas recommended, including the following lifestyle habits.

Klodas especially emphasized making improvements to diet, as the food people eat affects “every single risk factor that the AHA’s report highlights.”

“High blood pressure, high blood sugar, high cholesterol, excess weight – these are all conditions that are driven in part or in whole by food,” she said. “We eat multiple times every single day, which means what we eat has profound cumulative effects over time.”

“Even a small improvement in dietary intake, when maintained, can have a massive positive impact on health,” a doctor said. (iStock)

The doctor also recommends changing out a few snacks per day for healthier choices, which has been proven to “yield medication-level cholesterol reductions” in a month.

“Keep up that small change and, over the course of a year, you could also lose 20 pounds and reduce your sodium intake enough to avoid blood pressure-lowering medications,” Klodas added.

“Women should not view the AHA report as inevitable. We have power over our health destinies. We just need to use it.”

Common vision issue linked to type of lighting used in Americans’ homes

Common vision issue linked to type of lighting used in Americans’ homes

NEWYou can now listen to Fox News articles!

Nearsightedness (myopia) is skyrocketing globally, with nearly half of the world’s population expected to be myopic by 2050, according to the World Health Organization.

Heavy use of smartphones and other devices is associated with an 80% higher risk of myopia when combined with excessive computer use, but a new study suggests that dim indoor lighting could also be a factor.

For years, scientists have been puzzled by the different ways myopia is triggered. In lab settings, it can be induced by blurring vision or using different lenses. Conversely, it can be slowed by something as simple as spending time outdoors, research suggests.

Nearsightedness occurs when the eyeball grows too long from front to back, according to the American Optometric Association (AOA). This physical elongation causes light to focus in front of the retina rather than directly on it, making distant objects appear blurry.

Researchers at the State University of New York (SUNY) College of Optometry identified a potential specific trigger for this growth. When someone looks at a phone or a book up close, the pupil naturally constricts.

COMMON VISION ISSUE COULD LEAD TO MISSED CANCER WARNING, STUDY FINDS

“In bright outdoor light, the pupil constricts to protect the eye while still allowing ample light to reach the retina,” Urusha Maharjan, a SUNY Optometry doctoral student who conducted the study, said in a press release.

“When people focus on close objects indoors, such as phones, tablets or books, the pupil can also constrict — not because of brightness, but to sharpen the image,” she went on. “In dim lighting, this combination may significantly reduce retinal illumination.”

High-intensity natural light prevents myopia because it provides enough retinal stimulation to override the “stop growing” signal, even when pupils are constricted. (iStock)

The hypothesis suggests that when the retina is deprived of light during extended close-up work, it sends a signal for the eye to grow.

In a dim environment, the narrowed pupil allows so little light through that the retinal activity isn’t strong enough to signal the eye to stop growing, the researchers found.

In contrast, being outdoors provides light levels much brighter than indoors. This ensures that even when the pupil narrows to focus on a nearby object, the retina still receives a strong signal, maintaining healthy eye development.

The team noted some limitations of the study, including the small subject group and the inability to directly measure internal lens changes, as the bright backgrounds used to mimic the outdoors made pupils too small for standard equipment.

Researchers believe that increasing indoor brightness during close-up work could be a simple, testable way to slow the global nearsightedness epidemic. (iStock)

“This is not a final answer,” Jose-Manuel Alonso, MD, PhD, SUNY distinguished professor and senior author of the study, said in the release.
