Justin Timberlake sheds light on Lyme disease: What to know about symptoms, more
Timberlake shared in a July 31 post on social media that he was diagnosed with Lyme disease while on his two-year Forget Tomorrow World Tour.
"If you've experienced this disease or know someone who has -- then you're aware: living with this can be relentlessly debilitating, both mentally and physically," Timberlake wrote, adding, "When I first got the diagnosis I was shocked for sure. But, at least I could understand why I would be onstage and in a massive amount of nerve pain or, just feeling crazy fatigue or sickness."
The former *NSYNC member did not share further details of his diagnosis or treatment.
Timberlake's post about his diagnosis received hundreds of thousands of likes and comments, drawing attention to Lyme disease, a tick-borne infectious disease that, if left untreated, can affect the joints, heart and nervous system, according to the CDC.
Here is more to know about the disease.
What is Lyme disease?
Lyme disease, the most common vector-borne disease in the U.S., is caused by the bacterium Borrelia burgdorferi.
It is transmitted to humans via tick bites and is more likely to be contracted in the late spring, summer and fall.
In most cases, the tick must be attached to the skin for at least 24 hours before the bacterium can be transmitted. According to the CDC, removing a tick within 24 hours "greatly reduces" the risk of Lyme disease.

Lyme disease is most commonly found in the Northeast and upper Midwest, in states including Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Virginia and Wisconsin.
What are the symptoms of Lyme disease?
Symptoms of Lyme disease appear as soon as three days after the tick bite and include fever, headache and fatigue.
Another symptom of Lyme disease that can occur is a so-called "bull's-eye rash" that has red coloring and a red dot at the center of the rash, according to ABC News' chief medical officer Dr. Tara Narula. However it is not present in all cases and does not always appear as a bull's-eye -- sometimes it's just an expanding red rash.
Narula noted that a second stage of symptoms of Lyme disease can occur weeks to months after infection and may include issues such as cardiac inflammation, heart rhythm issues, neurological problems and meningitis.
A third stage of tick bite symptoms can occur months to years after a tick bite and include arthritis in large joints like the knee, as well as nervous system changes.
How is Lyme disease diagnosed and treated?
There are FDA-approved antibody tests used to diagnose Lyme disease, according to the CDC.
Most cases of Lyme disease can be treated with antibiotics over the course of 10 to 14 days. If left untreated, a wide range of symptoms may develop depending on the stage of infection including fever, rash, facial paralysis, an irregular heartbeat and arthritis.
What are ways to prevent Lyme disease?
The CDC recommends preventive measures such as treating your clothes and gear with products containing 0.5% permethrin.
They also recommend always doing a "tick check" after being outside and wearing insect repellent with Deet.

Ticks can also come into the home through clothing and pets, so the CDC recommends checking pets for ticks and tumble drying clothes on high heat for 10 minutes after coming indoors to kill ticks.
If you are ever in a situation where you are bitten by a tick, the CDC recommends tugging gently but firmly near the head of the tick until it is pulled away from the skin.
People who are outdoors in areas that may have ticks should also conduct a full body check when they return, including checking under the arms, in and around the ears, inside the belly button, behind the knees, in and around the hair, between the legs and around the waist, the CDC says.

Justin Timberlake speaks of 'debilitating' illness amid big spike in tick bites
As Americans head outdoors to enjoy the warm weather, more and more are being sickened by ticks, tiny creatures that can transmit a number of serious diseases. Justin Timberlake announced on July 31, that he is one of the estimated 476,000 people that are diagnosed with and treated for Lyme disease each year, an illness often transmitted through tick bites that Timberlake called "relentlessly debilitating." Meanwhile, emergency room visits related to tick bites have spiked in 2025, reaching their highest level in five years, according to the CDC's Tick Bite Data Tracker. The CDC reported by July 6 that the number of emergency department visits for tick bites had already exceeded nearly 10 years of July records, with 92 visits per 100,000 reported across the nation. Children ages 0 to 9 and people over the age of 70 were the most common of these ER visitors. Why is this tick season so bad? Climate change is one of the main factors impacting tick populations, according to experts at the Binghamton University Tick-borne Disease Center. 'Ticks can now move further north than they could before and establish populations,' Mandy Roome, associate director of the center, has said. 'Going back maybe 15 or 20 years ago, there wasn't much of an issue. Ticks were still around, people still got tick-borne diseases, but it wasn't quite the problem that it is now. We're also having really mild winters. Deer ticks are active anytime it's over 39 degrees, so we have a lot longer active periods for ticks now, unfortunately.' Roome said land use can also affect the tick population. She said construction activity can create new habitats for animals like mice, which can pass on pathogens to ticks. What is Lyme disease? Justin Timberlake shares 'debilitating' diagnosis 'The deer, the mice—when their ranges and numbers increase, we absolutely are going to see an expansion of ticks," Cassandra Pierre, an assistant professor of infectious diseases at the Boston University's Chobanian & Avedisian School of Medicine has said. "And longer warmer weather also allows for there to be more exposure to ticks, because people are out more." Why are tick bites dangerous? Ticks can carry several diseases capable of infecting humans and animals. People typically get Lyme disease, for example, when they are bitten by a tick carrying borrelia bacteria, according to the Mayo Clinic. Humans can also contract a variety of other pathogens from ticks, according to the CDC, including: Anaplasmosis Babesiosis Bourbon virus Colorado tick fever Ehrlichiosis Hard tick relapsing fever Heartland virus Lyme disease Powassan virus Rickettsia parkeri rickettsiosis Rocky Mountain spotted fever Soft tick relapsing fever STARI Tularemia 364D rickettsiosis How to prevent tick bites If you expect to be in an area where ticks live, such a park, backyard or campsite, be extra careful when venturing outside. Ticks can be a year-round annoyance, but they are most active in the warmer months of April through September. Where are ticks found?

Get granny some AC: How using a fan when it's really hot out could actually make the elderly hotter
As New Yorkers sweat through relentless heat this summer, many are cranking up electric fans in a desperate bid for relief. But a shocking new study throws cold water on the popular cooling fix, warning it could actually backfire for older adults under certain conditions. Researchers found that in some blistering environments, sitting in front of a fan can increase body temperature in seniors — putting grandma and grandpa at greater risk of heat stroke and other serious health problems. 4 Thousands of people in the US suffer from heatstroke each year. SERHII – The study, conducted by scientists in Australia and Canada, tested how electric fans affect older adults under both dry and humid heat conditions. In the first phase, 31 adults aged 60 and older were exposed to hot, dry air — 100.4°F with just 15% humidity — simulating severe indoor heatwave conditions. Each participant completed four separate, three-hour sessions spaced at least 72 hours apart: fan only, skin wetting without a fan, skin wetting with a fan, and no intervention. Instead of cooling them down, fan use in dry heat caused participants' core body temperatures to rise by 0.5°F. They also reported feeling hotter and less comfortable. The findings suggest that, rather than cooling the body, the fan was actually pushing heat into it. Previous research from the same team found that fans used in hot, dry conditions tripled cardiac strain in older adults — a potentially deadly consequence for people with heart disease. 4 Extreme heat can exacerbate existing medical conditions and even accelerate aging. Felix Mizioznikov – 'In very hot and dry heat, fan use worsened all outcomes and should be discouraged for these conditions,' the study authors wrote. The second phase of the study focused on hot, humid conditions. This time, the researchers included 58 older adults — including 27 with a history of coronary artery disease, who had been excluded from the dry heat tests due to potential heart risks. In these tests, room temperatures again reached 100.4°F, but with 60% humidity. Unlike in dry heat, fan use in humid conditions slightly lowered participants' core temperatures by an average of 0.18°F. It also boosted sweating and made participants feel cooler and more comfortable overall. An earlier study by the same team showed that fans — with or without skin wetting — also helped reduce cardiac strain under similar humid conditions. 4 Studies suggest roughly 9 out of 10 homes in the US have some form of air conditioning. Satjawat – Together, researchers say the findings challenge CDC guidelines that advise against using fans when temperatures exceed 90°F, citing a potential increase in body temperature and related health risks. 'While air conditioning is an effective way of staying cool, it's not available to everyone, especially those most vulnerable to the heat such as the elderly and people with heart disease — so it's positive news that low-cost alternatives are effective, Dr. Daniel Gagnon, a researcher at the Montreal Heart Institute and co-author of both studies, said last year. 'Importantly, the study has shown that the weather conditions affect the type of cooling strategy that should be used — a vital piece of information that will help older people to stay safe in heatwaves,' he added. 4 Extreme heat events are becoming more frequent and intense in the US. Günter Albers – Heat waves are becoming more frequent across major US cities — and more dangerous, as sweltering overnight temperatures offer little relief from the day's heat. Each year, an estimated 60,000 Americans end up in the emergency room due to heat-related illnesses like heat exhaustion and heat stroke — and more than 13% of those cases require hospitalization, according American Medical Association. In New York City, the danger is already playing out. On June 25, a record-breaking 99°F scorcher sent 141 people to emergency rooms with heat-related issues — the highest single-day total since 2017. Extreme heat is the deadliest weather-related hazard in the US, with more than 14,000 deaths directly linked to heat since 1979. But experts warn the true toll may be far higher, as heat is often underreported or overlooked as a contributing factor. In New York alone, more than 500 people die prematurely each summer due to extreme heat — the vast majority inside their homes without air conditioning. The city operates cooling centers to help vulnerable residents, but for those relying on electric fans at home, the new research makes one thing clear: check the humidity. If it's dry, that fan could leave you even hotter than before.
