Light Pollution Disrupts Mosquitoes’ Diapause, Extending Biting Season and West Nile Virus Risk, Study Shows

A recent study by researchers at Ohio State University has suggested that light pollution in urban areas can have a significant effect on the behavior of mosquitoes that transmit West Nile virus. The study found that exposure to artificial light at night may disrupt the winter dormancy period, known as diapause, for female Northern house mosquitoes, causing them to delay their period of dormancy and remain active longer into the fall. This delay can potentially put humans and animals at greater risk of contracting West Nile virus, which is transmitted when infected mosquitoes feed on mammals.

The study also found that exposure to light pollution suppressed the accumulation of water-soluble carbohydrates, an essential food source for mosquitoes during the winter. Additionally, the accumulation of the sugar glycogen was reversed in mosquitoes exposed to artificial light at night. While this delay in diapause may have negative consequences for mammals in the short term, it could also reduce the survival rate of mosquitoes in the long term, as they may fail to fully engage in preparatory activities needed to survive the winter.

These findings have important implications for understanding the impact of human activity on the behavior of insects and their potential to transmit diseases. The researchers plan to carry out field studies to see if these lab findings hold true in the wild. As artificial light at night continues to be a growing concern in urban areas, these results suggest the need for further investigation into the effects of light pollution on insect behavior and the transmission of disease.

8 Daily Habits to Support Your Heart, Kidney and Metabolic Health

8 Daily Habits to Support Your Heart, Kidney and Metabolic Health

8 Daily Habits to Support Your Heart, Kidney and Metabolic Health

(Feature Impact) When it comes to protecting your heart, supporting your kidney function and improving your metabolic health, you’ll find the advice for each one looks similar. That’s because your body’s systems are deeply interconnected: what affects one will have ripple effects across the others.

Cardiovascular-kidney-metabolic health, or CKM health, is a perfect example. When any one of these systems is compromised, it can lead to problems with the others. Therefore, it’s not uncommon for health problems like heart disease, stroke, diabetes and kidney disease to develop or worsen simultaneously – a condition collectively known as CKM syndrome.

The reverse is also true, so habits that are healthy for your heart will have a positive effect on your kidneys and metabolic system and vice versa. Consider these simple strategies that align with the American Heart Association’s Life’s Essential 8, a list of healthy steps that can improve overall health. Learn more about how these habits and health measures affect your CKM health at Heart.org.

  1. Choose Healthy Foods – Food is your body’s fuel, so fill your tank wisely. Certain types of foods can help your blood pressure, cholesterol, blood glucose and triglycerides stay within healthy ranges, while poor nutrition can push those numbers into more dangerous territory. Focus on vegetables, fruits, whole grains, plant-based proteins (e.g. beans, legumes and nuts) and lean animal proteins (e.g. seafood, skinless poultry and low-fat dairy). Drink plenty of water throughout the day and limit added sugar and salty or fatty foods.

  1. Stay Physically Active – Exercise doesn’t have to feel like a chore – in fact, some of your favorite hobbies may already count. The American Heart Association recommends aiming for 150 minutes per week of moderate physical activity like dancing, gardening or walking, moving quickly enough to elevate your heart rate and break a light sweat. Alternatively, choose 75 weekly minutes of vigorous exercise that gets you breathing hard and fast; think running, swimming, playing tennis or riding your bike on hilly terrain.
18083 detail embed3
  1. Avoid Nicotine – Tobacco and other nicotine products can raise your blood pressure, damage blood vessels and increase your risk of heart attack and stroke, which are all bad news for your CKM health. If you’re currently trying to quit, you aren’t alone, so don’t be afraid to seek out support groups and resources to help. 
18083 detail embed4
  1. Prioritize Healthy Sleep – Sleep gives your body a chance to rest and recover from the day, but it’s often one of the first things people sacrifice when life gets busy. Poor sleep can increase your risk for heart disease, weight gain and other issues. Aim for a solid 7-9 hours a night. Keep your bedroom cool, dark and comfortable, and do your best to limit distractions like late-night smartphone scrolling.
18083 detail embed5
  1. Watch Your Blood Pressure – When your blood pressure is high, it forces your heart to work harder to pump blood through the body, which can weaken it over time. It can also damage the delicate arteries in and around the kidneys, putting CKM health further at risk. Information is power, so check your blood pressure frequently to know whether further action is needed to keep it under control.
18083 detail embed6
  1. Manage Your Blood Sugar – High blood sugar can damage the kidneys, eyes, blood vessels and more, thereby increasing your chance of developing harmful CKM conditions. Controlling blood sugar is particularly important for people with diabetes. If you don’t have diabetes and still experience frequent blood sugar spikes and crashes, talk to your doctor.
18083 detail embed7
  1. Control Your Cholesterol – Cholesterol comes in both “bad” (LDL) and “good” (HDL) forms, requiring a balancing act to keep your levels within a healthy range. If LDL is high and HDL is low, your risk of clogged blood vessels, heart attack and stroke are higher. Healthy levels keep blood flowing to your heart and kidneys, supporting your metabolic health in the process. See your doctor for regular bloodwork so you can monitor cholesterol changes.
18083 detail embed8
  1. Maintain a Healthy Weight – Since excess body weight puts pressure on the heart, kidneys and other organs, a healthy body weight helps lower your risk of CKM syndrome. Whether you’re hoping to maintain or reduce your weight, regular exercise, healthy eating and quality sleep are all great ways to achieve your goals.

3 Steps to Support Mental Health for Rural Youth

Mental Health for Rural Youth Young people face a growing number of pressures, including academic expectations, social responsibilities, complex family situations and uncertainty about their own futures. Mental health support is important for all – but in many rural areas, those pressures are even greater. If the rural mental health crisis affects you or a loved one, consider these ways to help.

3 Steps to Support Mental Health for Rural Youth

(Feature Impact) Young people face a growing number of pressures, including academic expectations, social responsibilities, complex family situations and uncertainty about their own futures. Mental health support is important for all – but in many rural areas, those pressures are even greater.

According to the Centers for Disease Control and Prevention, the suicide rate for rural youth ages 15-19 is 74% higher than their urban counterparts. Barriers like limited insurance coverage, unreliable internet for telehealth, scarce providers, long drive times and lack of public transportation make it harder to get mental healthcare when it’s needed. Plus, asking for help can feel like opening oneself up to judgment and stigmatization.

That’s why Rural Minds, the only nonprofit focused on mental health for rural communities, created the Rural Youth Mental Wellness pilot program supported by Boehringer Ingelheim. It was developed by an advisory committee made up of rural youth to provide their peers with practical, free, accessible mental health resources. Incorporating feedback on the pilot, the updated program sponsored by the Sompo Foundation is now launching its national rollout.

“A young person’s ZIP code should never determine whether they can access meaningful mental health support where and when they need it,” said Jessica L. Schleider, Ph.D., director, Lab for Scalable Mental Health, Northwestern University. “Our lab is thrilled to partner with Rural Minds as they champion evidence-based, anonymous, freely available support tools designed to overcome barriers to help-seeking faced by rural youth across the country.”

If the rural mental health crisis affects you or a loved one, consider these ways to help.

Break the Stigma Surrounding Mental Health

In communities where self-reliance is valued, asking for help can sometimes be viewed as a sign of weakness. Young people who feel unheard and unsupported often struggle with being vulnerable, so they continue carrying their increasingly heavy burdens alone.

Parents, educators, healthcare providers, community leaders and peers can work to change that culture by normalizing mental health conversations. This includes helping teenagers feel seen and accepted by educating them on mental health issues and coping strategies, listening to their experiences without judgment, sharing your own stories and reminding them it’s courageous to seek support.

18109 detail embed2Consider Single-Session Interventions

The first step is always the hardest when it comes to seeking mental health support, and not every struggling young person is ready or able to see a therapist. With access to free, confidential, self-guided materials to begin building mental wellness skills, the first step may be less scary.

Single-Session Interventions (SSIs) are brief, structured online courses designed to teach youth practical skills for handling stress, low mood, self-image and more. The Rural Youth Mental Wellness Program offers SSIs in partnership with Project YES (Youth Empowerment and Support), a free digital resource developed with Northwestern University’s Lab for Scalable Mental Health at the Feinberg School of Medicine.

Anonymous access to SSIs through the partnership provides strategies for:

  • Improving mood
  • Rethinking body image
  • Reframing negative thoughts
  • Knowing your power to change
  • Taking steps toward goals
  • Protecting LGBTQ+ pride
  • Handling self-harm urges
  • Staying safe amid dark thoughts

Each SSI typically takes 5-10 minutes. Although SSIs are not a replacement for therapy, they provide a research-backed source of support for young people experiencing bouts of stress or low-to-moderate distress.

Know When to Seek Professional Help

Self-guided resources and supportive conversations are a valuable starting point, but sometimes young people need qualified professional help. Look for symptoms like worsening mood or behavior, substance use, self-harm or difficulty managing everyday tasks, and take teens seriously when they express dark feelings.

Doctors and counselors can provide personalized support for youth in crisis, and the 988 Suicide and Crisis Lifeline offers free, confidential 24/7 support for mental health by dialing 9-8-8.

“I grew up in a small town where mental health was almost taboo,” said committee member Asheton Medlin. “Being part of the committee that built this program let me help make sure rural youth today have the support I didn’t. I’m excited to help bring these resources to them because this generation deserves the chance to grow up and change the world.”

Build Heart-Healthy Habits That Last with 4 Simple, Everyday Steps

(Feature Impact) Your heart works around the clock, making heart health one of the most important parts of your overall well-being. The good news is improving heart health doesn’t require an overnight transformation. Small, consistent lifestyle changes and healthy habits, including staying active and making smart food choices, can help support cardiovascular health.

Sit Less Throughout the Day

If you work in an office setting, spending long periods sitting may be the norm. Even if you exercise regularly, those long-seated hours may affect heart health. Look for opportunities to move more by taking short walking breaks, standing while on the phone, stretching between meetings or taking the stairs instead of an elevator.

Prioritize Foods That Support Heart Health

A heart-healthy eating pattern can begin with foods that are low in saturated fat and sodium, and provide beneficial vitamins and plant compounds, like fresh, juicy grapes. They contain 7% of the daily recommended intake of potassium per serving, are a good source of vitamin K and deliver beneficial antioxidants and other polyphenols, including flavonoids, that can help relax blood vessels and promote healthy circulation.

Some studies also suggest grapes have a beneficial impact on blood lipids and more. In fact, one study found women who consumed 1 1/4 cups of grapes every day benefited from reduced blood triglyceride levels, LDL cholesterol levels, inflammatory proteins and other markers of heart disease.

Whether enjoyed as a snack, added to salads or blended into smoothies, Grapes from California make it easy to add more heart-smart nutrition throughout the day. For example, this Warm Lentil, California Grape and Arugula Salad includes a quick homemade rosemary lemon vinaigrette to pack in the flavor and complement black lentils and sweet grapes.

Cut Back on Added Sodium

Adding heart-healthy foods like grapes to your menu is a good place to start, but caring for your cardiovascular system is also about what you’re not eating. Many packaged and restaurant foods contain more sodium than some people realize, making it important to read nutrition labels, prepare more meals at home and flavor foods with herbs, spices, citrus or vinegar instead of extra salt to support healthy blood pressure.

Make Good Sleep a Priority

Quality sleep affects many aspects of health, including cardiovascular. Adults should aim for 7-9 hours of sleep each night in a cool, comfortable environment. To get a good night’s rest, try limiting screen time before bed, blocking out light and avoiding alcohol or caffeine in the evenings.
