Why Carpal Tunnel Syndrome Is More Than Just a Typing Disorder
It's a condition that can significantly impact your work, hobbies, and overall quality of life. The good news? Over the last decade, our understanding of how to diagnose and treat CTS has advanced dramatically. Whether you're just starting to notice symptoms or have been struggling for years, there's a clear path to relief.
This guide will walk you through what's happening inside your wrist, bust some common myths, and explain the modern, effective treatments that can get you back to feeling your best.
Imagine a narrow tunnel running through your wrist. This isn't a metaphor—it's a real anatomical space called the carpal tunnel. Through this passage run the tendons that flex your fingers and, critically, the median nerve. This nerve is a superstar; it provides sensation to your thumb, index finger, middle finger, and half of your ring finger, and it controls the muscles at the base of your thumb [1].
Carpal Tunnel Syndrome occurs when the space inside this tunnel narrows or the tissues within it swell, putting pressure on the median nerve. Think of it like a garden hose getting kinked. When the flow of water (in this case, nerve signals) is restricted, problems arise. The result is pain, numbness, tingling, and eventually, weakness in your hand and fingers [9]. As detailed in information from the National Institute of Neurological Disorders and Stroke, ignoring these signals can lead to permanent nerve damage [5].
Many people believe CTS is caused exclusively by typing on a computer all day. While repetitive hand and wrist movements are certainly a major risk factor, they are only one piece of a much larger puzzle. The development of CTS is often multifactorial.
According to the Centers for Disease Control and Prevention (CDC), a combination of personal and occupational factors often contributes. Other significant risk factors include:
Blaming your keyboard alone oversimplifies the issue and can prevent you from addressing other underlying factors that are just as important for management and prevention.
Getting an accurate diagnosis is the first and most critical step toward relief. Your doctor will start by listening to your story—when the symptoms started, what they feel like, and what makes them better or worse.
Next comes a physical examination. Your doctor may use a few classic in-office tests to try and reproduce your symptoms:
While these tests are helpful, they aren't foolproof [7]. For a definitive diagnosis, your doctor will likely recommend electrodiagnostic studies. These tests, which include nerve conduction studies (NCS) and electromyography (EMG), measure how well your median nerve is functioning. They are considered the gold standard for confirming CTS and determining its severity [8]. In some complex cases, an ultrasound or MRI might be used to get a better look at the structures in the wrist [6].
For most mild to moderate cases of CTS, the treatment journey begins with non-surgical, or 'conservative,' approaches. The goal is simple: reduce pressure on the median nerve and allow it to heal.
A 2021 study confirms that a few key strategies are highly effective first-line treatments [2].
If your symptoms are severe, if you have muscle weakness, or if conservative treatments haven't provided enough relief, it may be time to consider surgery. The procedure, called a carpal tunnel release (CTR), involves cutting the ligament that forms the 'roof' of the carpal tunnel. This creates more space for the median nerve, instantly relieving the pressure.
CTR is one of the most common and successful procedures in medicine. There are two main ways to perform it:
Both techniques are highly effective [2]. However, studies suggest that the endoscopic approach often leads to a faster recovery and less immediate postoperative pain, allowing patients to return to their activities sooner [3]. The idea that surgery is a painful, last-ditch effort with a long recovery is largely outdated. For the right patient, it offers a definitive, long-term solution.
Ultimately, there's no single 'best' treatment for everyone. The right approach for you will depend on the severity of your symptoms, your overall health, your daily activities, and the results of your diagnostic tests.
The most advanced clinical thinking advocates for an individualized plan that combines all this information [8]. Working with your doctor, you can weigh the pros and cons of each option. Some patients find lasting relief with a simple night splint, while for others, surgery is the most direct path to restoring full hand function and ending the sleep-disrupting pain for good.
Carpal Tunnel Syndrome can feel like a frustrating and persistent intrusion on your life, but you don't have to just live with it. With a better understanding of the condition and a wealth of effective, evidence-based treatments available, relief is within reach. The key is to listen to your body's signals and seek medical guidance early. A proactive approach, guided by a healthcare professional, is your best bet for preventing long-term issues and ensuring a full recovery.

Summer nights are getting warmer due to climate change, sparking health concerns
When you typically think about extreme heat, a sweltering, sunny day may come first to mind. But climate scientists are also sounding the alarm on warm summer nights, saying they are quietly becoming a worrisome consequence of climate change -- and a serious public health concern. When nighttime temperatures don't drop low enough relative to peak daytime heat, it is harder for people to cool off, according to Climate Central, a nonprofit organization that analyzes and reports on climate science. Extreme heat is the leading weather-related killer in the United States, with heat waves responsible for more deaths than other extreme weather events like tornadoes, flooding, or hurricanes, according to the National Weather Service. This week, more than 200 million people across the U.S. from South Dakota to Florida and up the East Coast to Boston, are on alert for widespread, dangerous heat. Extreme heat warnings have been issued for large cities from Iowa to Florida, including New Orleans, Memphis, St. Louis, Omaha, Des Moines, Savannah, Raleigh, Charleston and Sioux Falls. In these areas, feels-like temperatures are forecast to soar into the triple digits during the afternoon hours, with the dangers remaining even after the sun sets. A dangerous temperature trend From 1970 to 2024, Climate Central analyzed average summer nighttime temperatures in 241 locations across the U.S. The organization found that these temperatures have warmed in nearly all locations, increasing by 3.1 degrees Fahrenheit on average. Looking to the future, warm summer nights are expected to become increasingly frequent in the coming decades, according to the Environmental Protection Agency (EPA). In many regions across the country, the EPA reports nighttime temperatures are projected to remain above 70 degrees Fahrenheit more often. Health risks The most serious health impacts of a heat wave are often associated with warm overnight temperatures, the EPA warns. The Centers for Disease Control and Prevention (CDC) echoes these warnings, saying if the air stays too warm at night, the body faces extra strain trying to regulate body temperature. Without this crucial drop in temperature, vulnerable populations -- including elderly people, children, and those with pre-existing conditions -- face heightened health risks, according to the agency. MORE: Heat stroke vs. heat exhaustion: Safety tips as dangerous temperatures hit US Prolonged exposure to high heat in the evenings has been linked to poorer sleep quality, which can impair immune function, exacerbate mental health issues, and increase the risk of chronic conditions such as heart disease, according to the CDC. While extreme heat and triple-digit temperatures frequently are the focus of attention and grab headlines, the lack of adequate overnight cooling is also a serious concern that amplifies the impacts of heat. Overnight cooling is essential for not just the human body, but infrastructure and ecosystems to recover after a hot day. Cities feel heightened temperatures Warmer overnight temperatures are also fueled by urban development. Cities with heat-retaining concrete and asphalt are particularly vulnerable to higher temperatures when vegetation is lost to more paved surfaces and buildings, according to the EPA. Compared with surrounding rural areas, urban locations have higher overall temperatures, especially at night. This is known as the "urban heat island" effect. Rising concentrations of greenhouse gases and increased atmospheric moisture are major contributors to the ongoing rise in nighttime temperatures seen in recent decades. As the atmosphere warms, it can hold more water vapor, which functions like an insulating layer, trapping heat and significantly limiting the amount of cooling that can occur at night, according to the National Oceanic and Atmospheric Administration (NOAA).

Heat advisory set in Ohio, 100+ degree weather coming. How to stay cool, latest forecast
Extreme heat is settling in over Ohio, making it feel like it's 100-plus degrees. According to the National Weather Service, the majority of the state will be under a heat advisory on Thursday, July 24, with heat index values — the measure of how hot it feels — of up to 104 degrees. And, the extreme heat could increase the potential for your car to break down as well as create a power outage at home because of the increased load on the electrical grid. Do you know what to do to keep yourself cool and safe during extreme heat? Here are some tips from the Ohio Department of Health and the U.S. Centers for Disease Control and Prevention, among others. What is 'corn sweat'? Does it affect Midwest humidity? Summer 2025 heat wave: Here are some surprising ways to stay safe. How to stay cool during Ohio's heat wave When the temperatures climb, the Ohio Department of Health has some advice on how to stay safe and cool. High-risk groups during a heat wave include infants, young children and older adults, according to the ODH, along with people with mental illness and chronic medical conditions such as heart disease, obesity, and poor blood circulation. People who are pregnant, work and exercise outdoors, and those without air conditioning in their homes are also considered high risk. Here's what ODH recommends: Drink cool fluids: Help your body cool down by staying well-hydrated with water. Don't wait until you are thirsty to start drinking water. Drink two to four cups of water every hour while working or exercising outside, and more on hot and humid days. Avoid alcohol or caffeine; they can add to dehydration and increase the effects of heat illness. Monitor or limit outdoor activities: Plan outdoor activities for the early morning or evening, when the sun is less direct and temperatures are generally cooler. Wear loose, breathable, light-colored clothing and a wide-brim hat, and use sunscreen that's at least SPF 30. Take frequent breaks in the shade or the air conditioning, and monitor youngsters playing outside. Check on your neighbors, family: Check on older neighbors, friends, and family, as well as those with chronic medical conditions, at least twice a day. Encourage them to stay in the air conditioning and to look for an air-conditioned shelter if necessary. Recommend that they take cool showers or baths to cool down. Don't forget your pets: Outdoor animals should have plenty of fresh water and a shady area to cool down. Also, never leave pets in vehicles. Even if the windows are cracked, the temperature inside can rise almost 20 degrees within the first 10 minutes. Heat waves and power outages: What to do if you lose electricity, AC Weather forecast for Akron, Canton, Columbus, Cincinnati Here's how hot it's expected to get around Ohio, according to the National Weather Service extended forecast. In the Akron-Canton region, the high today, July 23, will be near 90. The heat really hits on Thursday, July 24, when the high will be 93 with the heat index making it feel 101 degrees. And on Friday, July 25, temperatures will reach 88 degrees, with the chance of showers or thunderstorms. In Cincinnati, the high temperature will be near 93 today, July 23. On Thursday, July 24, the high will be 95 with the heat index reaching 106. And on Friday, July 25, the high will drop to 94 with the chance of rain. In Columbus, the temperatures today, July 23, will reach 91 degrees. The high on Thursday, July 24, will be near 94 degrees, with the heat index reaching 100. On Friday, July 25, the high temperature drops to 92, with the chance of showers or storms. What is the heat index? The heat index is the measure of how hot it feels when the air temperature is combined with the relative humidity, according to the NWS. It shows how comfortable it is to be outside since the body feels hotter in humid conditions. The more humid it is, the less sweat evaporates from people outdoors because the air already has so much moisture in it. That impacts the body's ability to cool itself, making it feel hotter. Know the symptoms of heatstroke, heat exhaustion and how they're different Heatstroke is a life-threatening condition characterized by several symptoms: A body temperature of 103 degrees or higher Red, hot, and dry or damp skin Rapid, strong pulse Headache Dizziness Nausea Confusion Unconsciousness People experiencing heatstroke need immediate medical assistance – call 911. Before help arrives, begin cooling the exhausted individual by any means possible, such as spraying them with a garden hose or using cool cloths. Move the person to a cooler place. Heat exhaustion is characterized by several symptoms: Heavy sweating Cold, pale, and clammy skin Fast, weak pulse Muscle cramps Tiredness or weakness Dizziness Headache Nausea or vomiting Move the exhausted person to a cool place, loosen their clothing, and have them sip water. If possible, put cool, wet cloths on the person or have them take a cool bath. If the individual begins throwing up, or if symptoms get worse or last for over an hour, then call 911. Pets in the heat: How to keep your dogs and cats safe and cool during the heat wave How to prepare for a heat wave and power outage If a heat wave is coming, the Federal Emergency Management Agency, American Red Cross and others have some advice on how to prepare for the hot weather and potential outages: Keep the heat out: If you are without air conditioning or lose power, you should try to keep the heat out of your house by closing the curtains or installing reflectors, such as cardboard covered in aluminum foil, to reflect the heat back outside, according to a national public service campaign to help Americans prepare for emergencies and disasters. FEMA also recommends moving to the basement or the lowest floor of the building since heat rises. Let some air in: If it's under 95 degrees, FEMA recommends opening a window and placing a fan near it to help with evaporative cooling. But keep the windows shut if the air temperature is about 95 or above. UNICEF recommends opening the windows at night to let in cool air. Stay hydrated: Drinking plenty of water helps prevent heat illnesses, according to the Red Cross, which says the average person needs about three-quarters of a gallon daily. Avoid sugary, caffeinated and alcoholic drinks. If you sweat a lot, add snacks or a sports drink to replace the salt you're losing. Gather emergency supplies: The Red Cross recommends having a two-week supply of food, water and medication on hand in case stores are closed during an outage. The organization advises having one gallon of water per person, per day, available in the event of an emergency. Be prepared to leave: FEMA recommends spending the hottest part of the day in a public building with air conditioning, such as a library, shopping mall or designated cooling center in your community, if your power is out. The Red Cross recommends having a go-kit — three days of supplies, including backup batteries and chargers for your devices — that you can carry with you in case you can't return home for a while. Protect these medications from summer heat If you have been prescribed medications, the heat can affect them if they are not stored properly (such as by leaving them in a hot car). And, some medications can make you more sensitive to the sun and heat, according to the Drug and Poison Information Center. Medicines affected by extreme heat include: Insulin Asthma inhalers Thyroid medications Epinephrine Medications that can increase the chance of a sunburn include: Acne medications Antibiotics Antihistamines Blood pressure medications Antipsychotics Non-steroidal anti-inflammatory drugs (NSAIDs) Oral contraceptives Sulfonylureas (used to treat type 2 diabetes) This article originally appeared on The Columbus Dispatch: Heat advisory in Ohio: Weather forecast, tips to stay cool, safe Solve the daily Crossword

As much of the US braces for extreme heat, statistics show 2,000 die from it annually
As extreme heat is forecast across much of the U.S. this week, health departments across the country are warning people to take steps to survive the potentially deadly weather. Extreme heat is the deadliest weather-related hazard in the U.S., claiming roughly 2,000 people annually, according to data from the Centers for Disease Control and Prevention (CDC). But experts note the official heat-related death toll may be undercounted due to heat sometimes not being considered as a factor in someone's death. The latest CDC statistics show that 150 heat-related deaths have already occurred in the United States in 2025, but the data is only partially tabulated due to delays in reporting. During the previous two years, more than 4,800 heat-related U.S. deaths were recorded, according to the CDC. Since 2020, there have been at least 9,436 heat-related deaths across the nation, the CDC noted. The CDC statistics show that the number of heat-related deaths increased from 1,156 in 2020 to 2,415 in 2023, before slightly declining to 2,394 last year. Meanwhile, the average number of heat waves that major U.S. cities experience each year has doubled since the 1980s, according to the federal government's Fifth National Climate Assessment. An analysis by Climate Central, an independent group of scientists and communicators that research climate change, found that between June and August 2024, the average person experienced an additional 17 days of "risky heat" because of human-amplified climate change, and that over the summer months, one in four people on the planet had no respite from the heat. The organization defined "risky heat" as days with temperatures hotter than 90% of the temperatures recorded in a local area from 1991 to 2020. Heat waves are becoming even more dangerous as overnight temperatures are too high to relieve people from the heat, prolonging heat stress and the associated heat risks. Extreme levels of heat stress have more than doubled over the past 40 years, a trend that is expected to continue, according to NASA's Jet Propulsion Laboratory in Southern California. Heat-related illnesses, like heat exhaustion or heat stroke, happen when the body cannot properly cool itself. While the body normally cools itself by sweating, during extreme heat, this might not be enough. In these cases, a person's body temperature rises faster than it can cool itself down and can cause damage to the brain and other vital organs. Hot days can affect anyone. Those who are pregnant, with a heart condition or other chronic condition, as well as children with asthma, can be especially affected. An estimated 70,000 people visit emergency rooms and an average of 10,000 are hospitalized annually due to heat. Between Jan. 1, 2023, and Dec. 31, 2023, there were a total of 119,605 emergency room visits across the country for heat-related illnesses, with 92% of those visits occurring between May and September, according to a report published in April 2024 by the CDC. July and August had higher than average ER visits due to heat than other warm-season months, including May, June and September, according to the report, which looked at data of ER visits caused by heat in 2023 and compared it to visits between 2018 and 2022. These findings are "consistent with record-breaking temperatures observed … in 2023," the CDC said. More than 200 million people across the country, from South Dakota to Florida and up the East Coast to Boston, are on alert for widespread, dangerous heat on Monday and into the new work week, and parts of the Southeast could experience the brunt of the sweltering conditions. The highest temperatures on Monday will be focused in the Southeast, from the Carolinas to Florida, where extreme heat indices -- that is, what the temperatures feel like when humidity is factored in -- are forecast to be between 105 and 115 degrees. Parts of Mississippi and Louisiana are on alert for heat indices up to 120 degrees. Extreme heat is also expected to continue on Monday and Tuesday in the Midwest, where over the weekend temperatures felt between 97 to 111 degrees from Lincoln, Nebraska, up into Minneapolis. The Northeast is in store for multiple days of dangerous heat. Heat indices in the Northeast are forecast to make it feel like the mid-90s to 104 on Monday. Officials in Boston, Philadelphia, New York City and Washington, D.C., have all declared a heat emergency for this week, which includes opening cooling centers and working with utility providers to encourage energy conservation and maintain electrical grid reliability. The New York City Emergency Management (NYCEM) and the Department of Health and Mental Hygiene are urging New Yorkers to take precautions to protect themselves from hot and humid weather that is expected to extend into Wednesday. NYCEM Commissioner Zach Iscol said this will the fifth heat emergency for New York City this season. "Prolonged heat like this is dangerous, especially for older adults, people with health conditions, and those without air conditioning," Iscol said in a statement. "Stay hydrated, limit outdoor activity, and find a Cool Option, whether it's a City cooling center like a library or a private space such as a friend's or relative's home."
