Health officials issue urgent warning after discovering first case of deadly bacteria carried by tick in US: 'Raising public awareness … is critical'
Researchers in Connecticut have identified a dangerous pathogen carried by a rapidly spreading, invasive species of tick, Patch reported.
The Asian longhorned tick (Haemaphysalis longicornis) is considered invasive in the United States, with initial sightings recorded in 2010, 2013, and 2017.
Many tick species pose a risk to human health because of their efficacy in spreading disease, particularly bloodborne illnesses such as Lyme disease, babesiosis, and ehrlichiosis. That third pathogen is the one found by the Connecticut Agricultural Experiment Station.
According to NBC Connecticut, an Asian longhorned tick that tested positive for the bacterium responsible for ehrlichiosis "was found in Fairfield County sometime between 2021 and now."
"This discovery highlights the growing threat posed by invasive ticks," CAES Passive Tick and Tick-Borne Disease Surveillance Program Director Goudarz Molaei said. "Raising public awareness of emerging tick-borne illnesses is critical to both human and veterinary health."
Tickborne disease has been on the rise for decades.
"As typically colder and drier climates become warmer and wetter, there has been an expansion of ticks in the northern hemisphere and at higher altitudes where they were previously unable to survive," a Pfizer advisory cautioned.
Scientists say rising temperatures and volatile weather patterns are driving their incursions into new areas, as a study published in Scientific Reports in January evidenced.
Because the Asian longhorned tick is a relative newcomer to the U.S., researchers are still working to determine the gravity of the risk it poses to both humans and animals.
Researcher Risa Pesapane co-authored a paper about the species and its effect on livestock, citing the deaths of three head of cattle in Oklahoma in 2021.

"To have been taken down by exsanguination by ticks, you can imagine that was tens of thousands of ticks on one animal," she explained.
At first glance, the worrisome proliferation of disease-spreading ticks seems insurmountable — but there are ways to reduce your risk of tick encounters and tick-related illnesses.
Chemical-free pest control methods are one way to avoid tick bites, and the Global Lyme Alliance recommends "products that use picaridin and oil of lemon eucalyptus" as effective deterrents on par with chemical pesticides.
Surprisingly, rewilding your yard may be another way to reduce the risk of encountering ticks, according to the David Suzuki Foundation.
"A growing body of ecological evidence … shows that replacing lawns with native plant gardens can disrupt tick-host interactions and reduce tick-borne disease risk, while also restoring biodiversity," the Foundation wrote.
Pesapane urged a multifaceted strategy for tick mitigation. "For a variety of reasons, I tell people you cannot spray your way out of an Asian longhorned tick infestation — it will require an integrated approach," she explained.

The science of sleep paralysis, a brain-body glitch making people see demons and witches
Sign up for CNN's Sleep, But Better newsletter series. Our seven-part guide has helpful hints to achieve better sleep. Baland Jalal lay in bed terrified, experiencing his own real-life horror film. Newly awake, the 19-year-old could see his surroundings but couldn't move or speak, and he didn't know why. He thought, ''My God, what do I do?'' Jalal, now 39, said of that moment in 2005. 'I tried to call my mom (and) dad, but no words would emerge from my throat. … I had this ominous presence of a monster, and it lifted my legs up and down. 'It strangled me, trying to kill me. And I was 100% sure that I was going to die,' Jalal added. 'It literally feels like all the evil of the universe is condensed into a bubble, and it's in your bedroom.' This type of hallucination is a hallmark for many people with sleep paralysis. It occurs during transitions into or out of rapid eye movement, or REM, sleep, similar to a traffic jam at a busy intersection — your brain, awake and alert, and body, still asleep and immobilized, collide momentarily, said Dr. Matthew P. Walker, director of the Center for Human Sleep Science at the University of California, Berkeley, via email. Following deep sleep, REM sleep is the next critical phase of sleep cycles, characterized by more dreaming that's also extra vivid and lifelike, and by faster heart rate and breathing. It's essential for memory, concentration, mood regulation and immune function. Jalal's experiences propelled him to study this phenomenon around the world. He aimed to discover the cause of sleep paralysis, he said, and why some people with the diagnosis 'have these powerful encounters where it feels like evil of epic proportions.' He has since earned a doctorate in psychiatry and is now a researcher in Harvard University's psychology department and a leading expert on sleep paralysis. He also treats patients struggling with it. An estimated 30% of people worldwide experience at least one episode of sleep paralysis in their lifetime, according to the Cleveland Clinic. How many of those people have recurring and impairing sleep paralysis isn't clear, but the percentage is likely low, Jalal said. Here's what else you should know about sleep paralysis and how it can be managed. In REM sleep, our bodies are paralyzed so we don't act out our dreams and risk hurting ourselves or others, Jalal said. Sleep paralysis episodes are usually only a few minutes long but can last up to 20 minutes, according to the Cleveland Clinic. During sleep paralysis, however, 'we regain consciousness before the muscles regain their freedom from REM-induced paralysis,' said Walker, who is also a professor of neuroscience and psychology at the University of California, Berkeley About 40% of people with sleep paralysis have visual, auditory or tactile hallucinations, such as pressure on one's chest or feeling out of body, Jalal said. For about 90% of those individuals, the illusions are terrifying. They can include ghosts or cat- or alien-like creatures, and their actions can be as innocuous as simply approaching them or as nefarious as molesting or trying to kill them. In Jalal's academic travels, he discovered the contents and interpretations of hallucinations, views on what causes sleep paralysis, and episode frequency and duration can all also have a cultural basis. People living in Egypt and Italy, for example, would often see witches and evil genies, hold them responsible and think they could die from sleep paralysis, Jalal said. People in Denmark, Poland and parts of the United States, on the other hand, have less supernatural or exotic explanations and less fear. 'Why do we see these monsters? Is it the dreaming imagery … that's spilling over into conscious awareness?' Jalal said. 'My answer to that is, according to my research, no, not exactly. But it's part of it.' When you're aware yet paralyzed and confused, your natural reaction is to escape that situation. Your brain is bombarding your body with signals to move, but your body can't return any feedback. Jalal's theory, in short, is that your brain says, 'to hell with it' and concocts a story it thinks your body must be facing to be experiencing such bizarre symptoms. The reduced activity in your prefrontal cortex — responsible for reason and logic — also contributes to hallucinations becoming 'extremely realistic and emotionally charged, amplified by an overly active amygdala, the brain's emotional alarm center,' Walker said. Though scientists know that wake-sleep glitch is what's happening during a sleep paralysis episode, they're not entirely sure why. But there are several factors that can increase the risk of fragmented sleep and sleep paralysis. Those factors include stress and related conditions such as anxiety, post-traumatic stress disorder (PTSD), bipolar disorder and panic disorder, experts said. Much of Jalal's sleep paralysis occurred when he was in school. Now when he has an episode once or twice per year, it's usually during a high-stress period, he said. (Once you've experienced sleep paralysis, you can be conscious of that during an episode but still feel afraid.) Other common contributors are sleep deprivation, jet lag, an irregular sleep schedule, sleep disorders such as narcolepsy, and genetic factors, Walker and Jalal said. Obstructive sleep apnea, substance use disorder and some medications — such as those for attention deficit hyperactivity disorder — can also raise risk, according to the Cleveland Clinic. As scary as sleep paralysis may sound, it's not actually dangerous, experts said. But depending on how recurring it is, sleep paralysis can be a sign of an underlying sleep disorder, Jalal said. Regular episodes can also lead to anxiety around sleep and then avoidance of sleep, Jalal said. This pattern can interfere with your daily energy and ability to function. And if you often have frightening hallucinations, that can lead to anxiety or trauma-like symptoms. Sleep paralysis can be significantly alleviated with several practices or treatments, Walker said — starting with healthy sleep habits, for one. That includes seven to nine hours of restful sleep nightly. Maintaining a sleep schedule consistent in quality and quantity 'acts like tuning your internal clock, reducing the chance of disruptive wake-sleep overlaps — much like ensuring all parts of an orchestra are synchronized for perfect harmony,' Walker said. Also prioritize stress management, by using, for example, mindfulness and relaxation exercises, Walker said. Therapies can relieve certain underlying issues triggering sleep paralysis, including cognitive behavioral therapy, especially the version for people with insomnia. In more serious situations, medications are sometimes used, Walker said. Those include SSRI (selective serotonin reuptake inhibitor) or tricyclic antidepressants that can help manage a smooth flow between sleep stages or even reduce the REM phase of sleep. Generally, boosting the brain's serotonin levels somehow compensates for the loss of the REM phase, Jalal said. But rarely, long-term antidepressant use has been linked with REM sleep behavior disorder. While the aforementioned treatments can help reduce the frequency or length of sleep paralysis episodes, there isn't yet a gold-standard treatment that can stop an episode once it's happening. Jalal has been trying to officially create one over the past decade, though, and it's self-inspired. Called meditation relaxation therapy, the treatment reduced sleep paralysis by 50% after eight weeks for six people with narcolepsy, compared with a control group of four participants, found a small pilot study Jalal published in 2020. He currently has another study of the same treatment with more participants underway at Harvard. And the steps of Jalal's therapy are as follows: Cognitively reappraise the meaning of the attack. Close your eyes and remind yourself that your experience is common and you won't die from it. Emotionally distance yourself from it. Tell yourself that since your brain is just playing tricks on you, there's no reason for you to be scared or risk the situation getting worse because of your own negative expectations. Focus on something positive. Whether it's praying or imagining a loved one's face, this refocusing can make thoughts more pleasant rather than monstrous. Relax your muscles and don't move. Some experts say trying to slightly move your fingers or toes one by one may help you come out of an episode sooner. But Jalal's fourth step advises against this movement since you'd still be sending signals to paralyzed muscles and maybe triggering hallucinations. Viewing your own biology in a more objective way by learning more about the scientific basis of sleep paralysis is also helpful, Jalal said.

Couples who cuddle before sleep reap these health benefits, study reveals
Snuggling with your partner could be a win-win for your health. Cuddling at night promotes more secure attachment between partners and lowers stress levels, according to a new study published in the Journal of Social and Personal Relationships. Researchers from Auburn University examined data from 143 heterosexual "bed-sharing" couples, analyzing associations between physical closeness at sleep onset, perceived stress, attachment insecurity and sleep disturbance. Factors including daytime sleepiness, income, age, relationship length, sleep diagnoses and whether children or pets sleep in the bed were also considered. The results revealed that couples who assumed a physically closer position upon going to sleep were indirectly linked with "lower couple insecure attachment" (when they have trouble connecting emotionally) and lower stress. The researchers found no "significant" associations between physical closeness at sleep onset and the chances of sleep disturbance. While stress was found to be lower among cuddlers, the research found that cuddling did not increase sleep quality. The researchers concluded that physical closeness at sleep onset "may be a promising and amenable avenue for improving relational and physiological well-being." Sleep expert Wendy Troxel, PhD — a RAND Corporation senior behavioral specialist and licensed clinical psychologist in Utah — shared with Fox News Digital how these findings highlight the "vital role" that shared time and physical touch play in emotional well-being. Troxel, author of the book "Sharing the Covers: Every Couple's Guide to Better Sleep," commented on the "interesting" finding that cuddling did not influence sleep quality. "This suggests that it's the moments spent together before falling asleep — not necessarily sharing the entire night — that have the greatest positive effect on a relationship," said the expert, who was not involved in the study. "The simple act of cuddling before sleep likely triggers powerful psychological and physiological responses, such as increased emotional security and the release of oxytocin — the 'bonding hormone' associated with intimacy." These effects help reduce stress and deepen connection, which makes pre-sleep cuddling a "meaningful ritual for emotional health," Troxel said. "Whether you and your partner sleep together or apart, don't skip the cuddle before bed," she advised. "Even brief moments of closeness can enhance your relationship and overall well-being." While the study found that most couples sleep in the same position as their partner, 36.3% reported not touching or cuddling at night. Those who did touch reported sleeping back to back (19.6%), having some contact, like touching an arm or leg (23.1%), spooning (13.3%), intertwining (4.2%) and sleeping face to face (3.5%). Study co-author Josh R. Novak, PhD, associate professor at the Auburn University Department of Human Development and Family Science, confirmed in a statement to Fox News Digital that the more physically close position couples are in, the more feelings of "relational safety" were present due to lower stress. "Sleep is one of the most important ways we can manage our physical, relational and mental health," the researcher said. "Research has substantiated that sleep and relationship functioning are bidirectional and cyclical — meaning that bad sleep can negatively impact your relationship, and difficult relationship dynamics can lead to worse sleep." "Sleep is one of the most important ways we can manage our physical, relational and mental health." Novak added that non-sexual physical affection has generally been deemed "critical" for relationships, but there seems to be more "emotional and relational benefit" when there's full-body contact. "My study suggests that cuddling with a partner can be both a barometer of how a relationship is doing and a way to maintain or repair a relationship, as well as lower stress levels," he said. The researchers did not study how much time was spent in a cuddling position, leaving Novak to be "skeptical" of whether it leads to sleep disturbances. "What happens most often is that cuddling only happens for a bit until both partners fall asleep, but there could be a select few that cuddle throughout the whole night," he said. For more Health articles, visit "My hunch is that most use cuddling to induce sleepiness and the feeling of safety and to reduce stress and anxiety, and that afterward either their body temperature increases too much, or there is discomfort and the need to shift around becomes necessary." Novak encouraged couples to cuddle if stress levels are high, as it's a nonverbal way to feel "secure and safe." "Although research needs to substantiate this further, it might also imply that, in the face of conflict during the day that is not solved or repaired … cuddling might be a way to start that process and move toward repair," he added.

This food staple is great for your heart health: Expert
It's a rice that's nice for your health. Red yeast rice won't go down as the most popular variety on earth, but it's one that health experts say should be on your radar. 'Red yeast rice is a brightly coloured compound used in food and health products that is made by fermenting rice with a special type of yeast known as Monascus purpureus,' Amanda Frick, vice-president medical affairs at Thorne, said, per the New York Post. 'Red yeast rice has been used in traditional Chinese and Western botanical medicine to maintain healthy cholesterol levels and support blood circulation.' According to research, the crimson product contains naturally occurring compounds that can help keep total and LDL cholesterol, as well as triglycerides — the most common type of fat in the body — at optimal levels. The rice variety also contains other compounds such as phytosterols betasitosterol, campesterol, stigmasterol and isoflavones that can help keep your heart running smoothly. The magic element has less to do with what's in it as it does with what's on it. 'Red yeast rice does get a lot more attention for its health benefits than your everyday white or brown rice. The 'magic' of red yeast rice isn't actually in the rice itself — it's in what's grown on it,' Frick said. 'While white and brown rice provide a source of carbohydrates and fibre (depending on the rice type), they do not contain the additional nutrients like sterols and antioxidants that are found in red yeast rice.' While referred to as a rice, it's actually more commonly found in powdered form or as a supplement, or in some fermented foods. 'There are foods like fermented tofu, red rice vinegar and Japanese rice wine (sake) that include red yeast rice,' Frick said. 'Depending on the specific use in traditional Chinese medicine, it may be best prepared with other food ingredients or at a particular temperature. 'For uses in botanical medicine, it's often preferred to offer in a supplement form for consistent delivery of the bioactive compounds in red yeast rice.' A zest for life: Savouring Italy's lemons and the Mediterranean lifestyle Nostalgia of flavours in Hong Kong's cuisine scene The side effects tend to be relatively mild — gas, tummy troubles, headache and reddish poop — but red yeast rice isn't for everyone. 'As with any new dietary supplement, it's important to discuss starting red yeast rice with your health professional, who can determine if this is the right option for you, your lifestyle and your overall wellness plan,' she said. 'Women who are trying to become pregnant, pregnant or breastfeeding shouldn't take red yeast rice. Those who have kidney or liver disease also shouldn't take it. Additionally, it may interact with certain medications, supplements, alcohol and grapefruit.' One potential red flag is contamination. Some red yeast supplements can contain citrinin — a toxic byproduct of the fermentation process that can damage kidneys or liver.
