What’s healthier to drink: cold or hot water? Here’s what an expert says
NEWYou can now listen to Fox News articles!
A viral wellness trend asks a simple question — is warm or cold water healthier? — but the science behind it is more nuanced.
Previous research shows that food and beverage temperature has a measurable effect on things like anxiety and gut discomfort.
One of the most long-standing health claims is that ice-cold water boosts calorie burn by forcing the body to heat it up. While this is grounded in science, the actual impact may be minimal.
Ultimately, experts say, the health impact of water temperature depends on the goal — weight loss, athletic performance, digestion or comfort.
Does cold water boost weight loss?
“As per research, in the 90 minutes after consuming cold or room temperature water, energy expenditure increases minimally by 2.9% (cold water) and 2.3% (room temperature),” Tanya Freirich, a registered dietitian and diabetes expert in North Carolina, told Fox News Digital.

While the body does expend energy to warm up cold water, Freirich noted that it’s “not significant enough to make it worthwhile” for weight loss. Hot water doesn’t exactly melt fat, however, she added.
For those looking to lose or manage weight, Freirich suggests focusing on “how much” rather than “how cold.” She pointed to research involving overweight women who added an extra 1.5 liters of water to their daily intake. Over eight weeks, the participants saw measurable weight loss.

“The extra water may suppress the appetite or may play a part in energy production and expenditure,” Freirich said. The temperature of drinking water should not affect how well the body utilizes nutrients, she added, noting that more research is needed.
For those exercising in heat and humidity, the goal should be to rehydrate without excessive fluid loss through sweat. Research on thermoregulation suggests there is an ideal water temperature for athletes.

While drinking water can trigger sweating as the body regulates its temperature, 60.8 degrees Fahrenheit was associated with the least amount of perspiration.

“Cool, but not cold,” Freirich emphasized. Drinking water in this specific range helps the body rehydrate efficiently without causing gastrointestinal distress.
Warm water and digestion
There are several reasons someone might opt for warm water, including its effect on relaxation and digestion. Studies have found that warmer liquids can accelerate gastric emptying, effectively waking up the gut.

The benefits may be mental as well. Freirich points to research showing that hot black tea leads to lower levels of cortisol — the body’s primary stress hormone — and greater subjective relaxation after stressful tasks.

Medical triggers
Freirich warns that very cold water can cause difficulty for those with swallowing disorders, or can trigger migraines and “brain freeze” in people with sensitive nerves.

Furthermore, those with irritable bowel syndrome (IBS) may find that ice-cold drinks trigger digestive discomfort.
Ultimately, the best temperature is the one that encourages people to drink, the dietitian said. The general recommendation for adults is to consume seven to eight glasses of water per day.

“Most importantly, it is important for everyone to stay adequately hydrated,” Freirich said.

Cancer survivors may see surprising benefits from one specific exercise, study says
NEWYou can now listen to Fox News articles!
For many, surviving cancer comes with an automatic new lease on life but other survivors continue to experience physical and emotional challenges long after treatment ends.
Yoga may significantly reduce the insomnia, fatigue and mood disturbances many survivors endure after remission, a recent clinical trial found.
Mood disturbance and insomnia are “two of the most pervasive and troubling side effects experienced by cancer survivors for years after completing adjuvant treatments,” the researchers reported in the Journal of Clinical Oncology.
SIMPLE DAILY HABIT MAY HELP EASE DEPRESSION MORE THAN MEDICATION, RESEARCHERS SAY
They noted that both symptoms can substantially inhibit survivors’ ability to perform everyday activities.
The study, funded by the National Cancer Institute, compared 204 cancer survivors receiving standard survivorship care alone with 206 survivors who paired standard care with the Yoga for Cancer Survivors (YOCAS) program. Most of the participants were female breast-cancer survivors.
A clinical trial showed that yoga may help ease symptoms cancer survivors experience after treatments. (iStock)
YOCAS is a four-week intervention that incorporates two types of yoga – hatha, which is traditional and more active, and restorative, which is more passive. Both forms involve slow, gentle movements, breathing exercises and mindfulness, according to the American Society of Clinical Oncology (ASCO), which published a news release on the study’s findings.
Participants in the YOCAS group practiced yoga, on average, for 180 minutes each week over the course of three sessions.

At the end of the trial, the YOCAS participants reported overall improvements to mood, anxiety and fatigue, while the standard care group did not.
“Additionally, improvements in insomnia stemming from YOCAS yoga may be mediated by changes in overall [mood disturbance] and fatigue,” the researchers wrote.
“[The study is] an important advance because it offers survivors, who are likely already managing multiple medications, a non-pharmaceutical solution for reducing four different side effects at once,” Fumiko Chino, MD, a cancer researcher and associate professor in breast radiation oncology at MD Anderson Cancer Center, told ASCO.

Timothy Pearman, Ph.D., director of supportive oncology at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University, told Fox News Digital he was not surprised by the results of the study.
“Yoga is one of the most widely studied and validated interventions for managing cancer-related fatigue, mood disturbance and overall physical health,” Pearman said.
Pearman said his wife, Jenny Finkel, is a yoga teacher and received her continuing education at Duke University’s integrative medicine program, which focuses on yoga for cancer patients.
“There are now a number of cancer-specific yoga teacher training programs nationwide,” Pearman said. “Yoga is a wonderful thing because it is very modifiable, meaning that even for people who have significant physical impairment, the exercises can be modified so that anyone can participate.”
He added that yoga is affordable, too, because “all you need is a mat and someone to show you how to do it.”
Osteoporosis, an increased risk of cardiac problems and issues with balance and stamina are other physical symptoms related to cancer treatment that yoga can help mitigate, Pearman said.
Cancer survivors who took part in an average of three yoga classes a week for four weeks reported reduced anxiety and fatigue, according to a recent study. (iStock)
Shari Botwin, a licensed clinical social worker based in Pennsylvania, is a thyroid-cancer survivor who specializes in working with victims of trauma, including cancer. She turned to yoga months after her diagnosis and told Fox News Digital the practice has been “transformative.”
According to Botwin, cancer survivors she’s worked with have dealt with emotional challenges that affect their healing process, including depression and survivor’s guilt. In addition to the physical relief yoga can provide, she said it can also offer “a supportive environment of peers, some of which are cancer thrivers.”

Botwin added that yoga can help survivors who have lost parts of their body reframe their thinking.
“It supports us into moving into a place of self-compassion rather than shame and self-hatred,” she said.
Yoga can help cancer survivors who struggle with guilt or shame to find a community of understanding peers, according to some experts. (iStock)
Almost any type of exercise can be beneficial for cancer survivors, Pearman said. He advises his patients to stick to the type of exercise they enjoyed prior to cancer.

What to do if someone is having a stroke, after Jill Biden revealed debate-night fears
Jill Biden says Joe’s debate performance made her wonder if he had a stroke
Former first lady Jill Biden revises her account of former President Joe Biden’s disastrous 2024 debate, now alleging she feared he was suffering a stroke. This new statement from the first lady contrasts sharply with her earlier public affirmations of his performance. Contributor Ben Domenech scrutinizes the timing and motivations behind this sudden shift.

Former first lady Jill Biden has expressed her concerns about former President Joe Biden’s health status, noting that she feared he was having a stroke during a 2024 debate against President Donald Trump.
Biden struggled his way through the performance, with long periods of silence, confused facial expressions and stammered speech. In a recent interview with CBS, Jill Biden commented that she was “frightened.”
“I don’t know what happened,” she said. “I mean, when I watched it, I thought, ‘Oh my God, he’s having a stroke,’ and it scared me to death.”
JILL BIDEN SAYS SHE THOUGHT JOE WAS HAVING A STROKE DURING HIS DISASTROUS 2024 DEBATE PERFORMANCE
A stroke occurs when there is bleeding in the brain or when blood flow to the brain is blocked, according to Mayo Clinic.
Identifying a stroke may be difficult, as symptoms can vary.
Stroke symptoms can include balance loss, weakness, slurred speech, face drooping, confusion and severe headaches. (iStock)
The American Stroke Association (ASA) identifies the following key warning signs, using the acronym “B.E. F.A.S.T.”
- B – Balance loss
- E – Eye (vision) changes
- F – Face drooping
- A – Arm weakness
- S – Speech difficulty
- T – Time to call 911
In a situation in which someone could be having a stroke, “the only” thing to do is to call 911, Fox News senior medical analyst Dr. Marc Siegel told Fox News Digital.

The doctor emphasized other symptoms to watch for, including weakness on one side, slurred speech, difficulty processing information and confusion.
The ASA also warns that severe headaches can also be a sign of stroke.
At the first sign of stroke, 911 should be contacted immediately, as 1.9 million brain cells die every minute that a stroke goes untreated. (iStock)
Siegel advised against giving the person an aspirin, as it could worsen bleeding in the brain if that is the cause of stroke.
With an ischemic stroke, that type of medication could be helpful.

The ASA says 1.9 million brain cells die every minute that a stroke goes untreated, which means earlier treatment leads to higher survival rates and lower risk of disability.
“In medicine, we use the term ‘time is brain,’” Siegel said. “This means that the faster you bring the patient to the emergency room, the faster they can receive emergency treatment if indicated to reopen the blocked artery in the brain, if there is one.”
Brain imaging should be done within the first several hours after seeking medical attention for a stroke, according to a top physician. (iStock)
Brain imaging can also be done on arrival at the ER, which should occur within the first several hours, Siegel said.
Anyone who is experiencing a stroke should not drive themselves to the hospital, according to the CDC. Instead, the person should get a ride or call 911 — as treatment begins inside the ambulance.

About 80% of strokes are preventable, the American Heart Association states.
Prevention includes managing high blood pressure, diabetes, atrial fibrillation and other risk factors.
One in four survivors have another stroke within the next five years, per CDC data, so those at higher risk should prepare a prevention and treatment plan.
