Jellyfish are lurking off the Delaware beaches. How to stay safe, what to do if stung
While sharks seem to get all the attention, there's a more common concern, and if you run into them, you'll wish you hadn't.
We're talking about jellyfish. Here's what to know about them before you enter the water.
Summer fun in the First State: Welcome to our 2025 Delaware Summer Guide
Delaware is home to four different jellyfish, according to the Delaware Department of Natural Resources and Environmental Control. The jellyfish are:
Lion's Mane: The largest known jellyfish species in the world. The jellyfish's bright, trailing tentacles look like a lion's mane and are easy to spot because of their orange color. They can be as large as 6 to 12 inches across at the bell, or the rounded part at the top. The stinging cells are not known to be fatal to people. But the sting site will be very red and painful.
Atlantic Sea Nettle: This species is somewhat clear, with small white dots and reddish-brown stripes. Their sting is strong to severe, but not deadly to humans.
Moon Jellyfish: The moon jellyfish looks like an underwater flying saucer and lights up at night. They don't have strong enough stinging power to penetrate our skin, but if you happen to get brushed by one, you will feel a minor stinging sensation.
Sea Walnut: They're not true jellyfish, but Ctenophores, or comb jellies. If you do see one, don't fret. They're harmless to people.
While not fatal, some jellyfish stings are incredibly painful. According to the Mayo Clinic, after getting stung, you should do the following:
Carefully pluck visible tentacles with fine tweezers.
Soak the skin in hot water (110 to 113 degrees). It should feel hot, but not scalding. Keep impacted skin immersed or in a hot shower for 20 to 45 minutes or until the pain eases.
Apply 0.5% to 1% hydrocortisone cream or ointment twice daily to the affected skin.
If you are stung in the eye, you'll require medical care to control the pain and flush the eye.
If, by chance, you are stung by box jellyfish, which are found in tropical areas like the Indian and Pacific Oceans and not in Delaware, you will need medical attention and antivenom medication.
You may have seen the "Friends" episode where Monica was stung by a jellyfish. Don't do what Chandler and Joey did to fix the issue. Here's what to avoid, according to the Mayo Clinic.
Rinsing with human urine
Scraping out stingers
Rinsing with cold, fresh water
Applying meat tenderizer
Applying alcohol, ethanol or ammonia
Rubbing with a towel
Applying pressure bandages

TikTokers are obsessed with ‘fibermaxxing'. Here's what the experts say
Break out the chia pudding! The social media trend known as 'fibermaxxing' wants you to add more fiber to your daily diet. TikTok users tout the health benefits of including simple foods packed with the carbohydrate, including the relieving effects in the bathroom. Some TikTokers point to the recent rise in rates of colon cancer in young people, and note that eating fiber can help reduce the risk. To 'fibermaxx,' they're eating more chia seeds in their yogurt bowls, making meals with more beans, and taking supplements. While nutritionists are largely supportive of the trend, they have a few caveats. 'More isn't always better,' Mascha Davis, a registered dietician nutritionist and the owner of Nomadista Nutrition, told Health this week. 'Many people don't get enough fiber, but it's just important to be thoughtful about how you're doing it so that it's not too much too fast,' Kate Mintz, a registered dietitian at U.C.L.A. Health, also recently told The New York Times. Fiber is often used to fight constipation, helping stools to pass easier. 'Even if you suffer from constipation, increasing fiber all at once could make the situation worse before you get cleared out,' Jennifer House, a dietitian and founder of First Step Nutrition, also explained to Health. Getting too much fiber could lead to a bloated and uncomfortable experience, according to the Mayo Clinic. People need to be careful and methodical, and talking to a physician can help to determine what's a right amount, on a case by case basis. What's more, when people with autoimmune conditions such as Crohn's disease see symptoms flare up, they may need to eat less fiber to help manage symptoms. After stomach or intestinal surgery, doctors may also instruct you to keep a lower fiber diet that lets your digestive system heal. Before a colonoscopy the advice may be similar, helping to clear out the large intestine to ensure a successful procedure. But in general, Americans aren't getting enough fiber - more than 90 percent of women and 97 percent of men do not meet the recommended daily intakes. Total dietary fiber intake should be 25 to 30 grams a day from food, and not supplements, according to UCSF Health. Currently, dietary fiber intakes among American adults average about only 15 grams a day. Fiber is good for your gut, heart, and brain, and may also slash the risk of type 2 diabetes and heart disease. The Mayo Clinic recommends adding fiber to the diet slowly over a few weeks, letting the natural bacteria in your digestive system adjust to the change. Staying hydrated is also crucial and fiber works best when it absorbs water. So, what can you eat to fiber to the max? The next time you're at the grocery store, pick up some popcorn, beans, cereal, apples, oranges, peas, cauliflower, or carrots. Raspberries are a particularly fiber-rich fruit, packed with eight grams. "If you're going to have a cookie, have an oatmeal cookie," Joanne Slavin, a professor of food science and nutrition at the University of Minnesota, told the American Heart Association. "It doesn't take large amounts of fiber to have a real effect.'

With Trends Like 'Japanese Walking,' Is Walking Actually Exercise? We Asked Personal Trainers
You've heard of "hot girl walks," but what about "Japanese walking"? It's also known as interval walking training, and The Washington Post reports that even though this technique is now going viral on TikTok, Japanese walking came about after a 2007, Japan-based study concluded that high-intensity interval walking training may help protect against age-related decreases in muscle strength and peak oxygen uptake as well as increases in blood pressure. A more recent, July 2025 study found that prefrail and frail older adults who increased their walking cadence by 14 steps per minute had a 10% increase in the odds of improvement during a 6-minute walk test, which represents an advancement in mobility, function or endurance. With these positive study outcomes, you may be wondering: Does walking count as exercise? To find out, we asked personal trainers. Is walking exercise? Yes, walking is exercise, and experts across physical and mental health disciplines agree. Sergii Putsov, a certified personal trainer with a PhD in sports science, says, "Walking for just 30 minutes every day can lower your risk of severe cardiovascular disease and dementia." April Crowe, a licensed clinical social worker at Paramount Wellness Retreat, adds that "walking in natural environments also boosts cognitive function and creativity, thereby providing a unique kind of therapy." Does walking do more than build your heart's strength? As it turns out, yes. The Mayo Clinic has identified additional health benefits of walking. According to the medical center, walking can improve muscle endurance, boost energy, lower blood pressure, strengthen bones and support the immune system. You can see benefits both outdoors and on a treadmill. Walking alone can also change the shape of your body. In 2017, the Journal of Physical Activity and Health did a meta-analysis of 22 clinical trials related to walking and health. The results revealed that brisk walking reduced waist circumference, fat mass and body fat percentage to a "clinically significant" degree in men and women under age 50 living with obesity. It can also lead to overall weight loss. So, that "hot girl walk" you take could cause noticeable changes to your body if you stick to it. Is walking enough exercise on its own? Walking can certainly be combined with other activities as part of a circuit. You can also walk as a warm-up for jogging or cycling. Walking on its own can deliver results and may have fewer negative impacts on your body than other high-impact sports. Gregor Parella, also a CPT, says of walking for walking's sake: "It is much better than jogging because jogging can put undue pressure on your ankles, especially if you're heavily built. On the other hand, brisk walking is one of the best exercises because it tones up your leg and calf muscles without the same pressure on joints. Even walking at a slow pace is better than being stationary at home, but a faster pace will also hasten the health benefits. A 2019 study in Atherosclerosis found that "walking pace was inversely associated with the risk of death and development of cardiovascular disease" in male physicians with an average age of 67.8. In other words, the faster you walk, the lower your risk of death and cardiovascular disease. Regarding how long you should walk, the US Department of Health and Human Services recommends at least 150 minutes of moderate-intensity physical activity each week, or 30 minutes a day for five days, for substantial health benefits. This can include walking briskly at 2.5 mph to 4 mph. Walking at a slow or leisurely pace (2 mph or less) is considered a light-intensity activity, which is likely to produce some health benefits compared to sedentary behavior, but not as many benefits as walking health benefits of walking There are many health benefits to walking. Not only can the activity lower cortisol levels, like all forms of exercise, and give you some fresh air, but you may see various tangible improvements in the following health indicators: Better sleep. Low-impact physical activity can lead to more fitful sleep. One small 2020 study published in Sleep Health found that increasing daily steps led to better quality sleep, especially among women.

Lower risk of type 2 diabetes. According to the American Diabetes Association, walking at least 30 minutes per day could help you stave off type 2 diabetes. Increasing your daily step count may keep your glucose levels in check. According to the American Diabetes Association, walking at least 30 minutes per day could help you stave off type 2 diabetes.

Lower risk of cancer. Walking may even reduce your risk of some cancers. A 2013 study out of Cancer Epidemiology, Biomarkers & Prevention found that postmenopausal women who walked at least seven hours per week had a 14% lower risk of getting breast cancer than women who walked three hours or less every week. Ways to take your walking to the next level If you hit a plateau with your walking routine, you can add some intensity to your walk without having to jog or switch activities. Making your walk more rigorous could increase the number of calories burned by giving your body a new challenge. Ways to up the ante on your daily walk include: Increase the time of your walk. If you're currently walking 30 minutes a day, add more time in 10- or 15-minute intervals. Putsov recommends walking at least 45 minutes a day if your goal is weight loss. If you're currently walking 30 minutes a day, add more time in 10- or 15-minute intervals. Putsov recommends walking at least 45 minutes a day if your goal is weight loss. Increase your speed. You can also add more intensity by picking up speed. Free fitness workout apps with GPS enabled, including Nike Run Club, can help you track distance and time to calculate your pace.

Find a hill to increase the difficulty of your trek. You may also want to add retro-walking (walking backward) up an incline. Getty Images How to stay motivated while walking It's easy to get excited about a new workout routine initially, and it's just as natural to get bored or frustrated when you stop seeing major results. You may find music and podcasts helpful because they make time appear to pass more quickly. Just make sure that these sounds are background noise so that you can still be aware of your environment and those around you. Crowe also recommends setting clear, achievable goals. She says it can help to remind yourself about how far you've come, explaining, "Recording all achievements made during walks, whether through mobile apps or personal journals, will act as a reminder," which can push you harder next time. If going it alone is making it harder to stay on track, try walking with a partner or seeing if there is a walking club in your area. Parella says a walking buddy can increase your sense of accountability and make the experience more fun. You may also try new scenery to stay motivated during a walk. Getting some sun will increase your vitamin D intake, which may improve your mood. Walking safety tips Before you hit the sidewalk on your daily walk or hot girl walk, be sure you're well-equipped for the task. While a neighborhood or lakeside stroll may seem harmless, you still want to set yourself up for a safe return.
