Joanna Fong-Isariyawongse, University of Pittsburgh You stayed up too late scrolling through your phone, answering emails or watching just one more episode. The next morning, you feel groggy and irritable. That sugary pastry or greasy breakfast sandwich suddenly looks more appealing than your usual yogurt and berries. By the afternoon, chips or candy from the break room call your name. This isn’t just about willpower. Your brain, short on rest, is nudging you toward quick, high-calorie fixes. There is a reason why this cycle repeats itself so predictably. Research shows that insufficient sleep disrupts hunger signals, weakens self-control, impairs glucose metabolism and increases your risk of weight gain. These changes can occur rapidly, even after a single night of poor sleep, and can become more harmful over time if left unaddressed. I am a neurologist specializing in sleep science and its impact on health. Sleep deprivation affects millions. According to the Centers for Disease Control and Prevention, more than one-third of U.S. adults regularly get less than seven hours of sleep per night. Nearly three-quarters of adolescents fall short of the recommended 8-10 hours sleep during the school week. While anyone can suffer from sleep loss, essential workers and first responders, including nurses, firefighters and emergency personnel, are especially vulnerable due to night shifts and rotating schedules. These patterns disrupt the body’s internal clock and are linked to increased cravings, poor eating habits and elevated risks for obesity and metabolic disease. Fortunately, even a few nights of consistent, high-quality sleep can help rebalance key systems and start to reverse some of these effects.

How sleep deficits disrupt hunger hormones

Your body regulates hunger through a hormonal feedback loop involving two key hormones. Ghrelin, produced primarily in the stomach, signals that you are hungry, while leptin, which is produced in the fat cells, tells your brain that you are full. Even one night of restricted sleep increases the release of ghrelin and decreases leptin, which leads to greater hunger and reduced satisfaction after eating. This shift is driven by changes in how the body regulates hunger and stress. Your brain becomes less responsive to fullness signals, while at the same time ramping up stress hormones that can increase cravings and appetite. These changes are not subtle. In controlled lab studies, healthy adults reported increased hunger and stronger cravings for calorie-dense foods after sleeping only four to five hours. The effect worsens with ongoing sleep deficits, which can lead to a chronically elevated appetite.
Sleep is as important as diet and exercise in maintaining a healthy weight.

Why the brain shifts into reward mode

Sleep loss changes how your brain evaluates food. Imaging studies show that after just one night of sleep deprivation, the prefrontal cortex, which is responsible for decision-making and impulse control, has reduced activity. At the same time, reward-related areas such as the amygdala and the nucleus accumbens, a part of the brain that drives motivation and reward-seeking, become more reactive to tempting food cues. In simple terms, your brain becomes more tempted by junk food and less capable of resisting it. Participants in sleep deprivation studies not only rated high-calorie foods as more desirable but were also more likely to choose them, regardless of how hungry they actually felt.

Your metabolism slows, leading to increased fat storage

Sleep is also critical for blood sugar control. When you’re well rested, your body efficiently uses insulin to move sugar out of your bloodstream and into your cells for energy. But even one night of partial sleep can reduce insulin sensitivity by up to 25%, leaving more sugar circulating in your blood. If your body can’t process sugar effectively, it’s more likely to convert it into fat. This contributes to weight gain, especially around the abdomen. Over time, poor sleep is associated with higher risk for Type 2 diabetes and metabolic syndrome, a group of health issues such as high blood pressure, belly fat and high blood sugar that raise the risk for heart disease and diabetes. On top of this, sleep loss raises cortisol, your body’s main stress hormone. Elevated cortisol encourages fat storage, especially in the abdominal region, and can further disrupt appetite regulation.

Sleep is your metabolic reset button

In a culture that glorifies hustle and late nights, sleep is often treated as optional. But your body doesn’t see it that way. Sleep is not downtime. It is active, essential repair. It is when your brain recalibrates hunger and reward signals, your hormones reset and your metabolism stabilizes. Just one or two nights of quality sleep can begin to undo the damage from prior sleep loss and restore your body’s natural balance. So the next time you find yourself reaching for junk food after a short night, recognize that your biology is not failing you. It is reacting to stress and fatigue. The most effective way to restore balance isn’t a crash diet or caffeine. It’s sleep. Sleep is not a luxury. It is your most powerful tool for appetite control, energy regulation and long-term health.

Smart Gaming: How Parents Can Keep Kids Safe Online

Parents can enhance kids’ safety during online gaming by using privacy settings, researching games, enabling age checks, keeping personal information private, and utilizing parental controls and security tools.

Smart Gaming: How Parents Can Keep Kids Safe Online

(Family Features) Playing video games can be a fun, social experience. However, online gaming also poses real risks, especially for kids. As a parent, you don’t necessarily need to be a gamer yourself to help keep your children safe when the controller is in their hands.

Consider taking proactive steps like these to create a healthy online gaming environment for kids of all ages.

Check System Privacy Settings
As a first line of defense – before your child even starts gaming – spend some time in the device or console privacy settings. Here you can turn off sharing, disable location tracking, limit microphone and camera access and restrict how other users can interact with your child’s profile. Similarly, many games and platforms include built-in privacy settings that can be tailored to your child’s age and online experience. These settings may allow you to limit who can view your child’s profile or send a friend request, message or voice chat.

Research Games
Because not all games are created equal, look up game ratings through a service such as ESRB before buying or downloading to understand the maturity level of the game and determine if it’s appropriate for your child. To take it a step further, read reviews from other parents or watch gameplay videos to see if you deem not only the content but also the social interaction acceptable.

Use Facial Age Estimation
Online platforms are increasingly looking for ways to keep users safe, and that includes added levels of verification. As part of a multilayered approach to safety, Roblox is the first online gaming platform to require age checks for users of all ages to access chat features, enabling age-appropriate communication and limiting conversations between adults and minors. These secure age checks are designed to be fast, easy and secure using Facial Age Estimation technology directly within the app.

“Our commitment to safety is rooted in delivering the highest level of protection for our users,” said Matt Kaufman, chief safety officer at Roblox. “By building proactive, age-based barriers, we can empower users to create and connect in ways that are both safe and appropriate.”

Once age-checked, users are assigned to one of six age groups: under 9, 9-12, 13-15, 16-17, 18-20 or 21 and older, ensuring conversations are safe and age appropriate. Age checks are optional; however, features like chat will not be accessible unless an age check is completed. Chat is also turned off by default for children under age 9, unless a parent provides consent after an age check.

Keep Personal Information Private
It’s seldom a bad idea to be extra cautious when interacting with strangers online, even if they seem friendly enough while playing the game. Teach children what information not to share, including their full name, address, birthday, school name, phone number, email address, passwords or any photos that may contain any personal information (like a house number or school logo) in the background. Also encourage a screen name and generic avatar for added privacy.

Turn on Parental Controls
Designed to allow parents a supervisory role in their child’s online gaming experience, parental controls on many platforms include the ability to set schedules and limit playtime, restrict access to certain content or social features, require a password for purchases or set a spending limit.

Avoid Clicking Unfamiliar Links
Player profiles and in-game chats may include links to external sites, including those promising rewards or cheat codes. Because they can be used to gain access to personal information, remind your children to ask an adult before clicking any unfamiliar links while gaming so they can be verified as trustworthy.

Employ Privacy and Security Tools
While system or console-specific settings allow parents to set content restrictions, approve downloads, manage friends lists and more, additional layers of security are sometimes necessary. Extra safeguards such as antivirus and internet security software, DNS (domain name system) filtering and two-factor authentication can also be enabled to help keep kids safe online.

Why the First Year Behind the Wheel is the Most Dangerous: Data Shows Teen Drivers 3 Times More Likely to be in Fatal Crash

Teen drivers are significantly at risk of fatal crashes, with those aged 16-19 being nearly three times more likely to be involved in accidents than older drivers. The first year of driving presents heightened dangers, but with proper preparation, including coaching, technology, and smart insurance, families can mitigate these risks and promote safety.

Why the First Year Behind the Wheel is the Most Dangerous: Data Shows Teen Drivers 3 Times More Likely to be in Fatal Crash

(Feature Impact) The driver’s license photo may be slightly awkward, but the milestone is unforgettable. For families, a newly licensed teen means independence, busy schedules and a new set of responsibilities.

Motor vehicle crashes remain one of the leading causes of death for U.S. teens, according to the Centers for Disease Control and Prevention (CDC). Data from the National Highway Traffic Safety Administration shows drivers ages 16-19 are nearly three times more likely to be involved in a fatal crash than drivers 20 and older, per mile driven.

The statistics are serious, but they’re also manageable.

“With the right preparation, teen driving doesn’t have to feel overwhelming,” said Susan Irace, manager, divisional claims at Mercury Insurance. “Experience is what young drivers are building. Parents can help shorten that learning curve with structure, technology and smart coverage decisions.”

Why the First Year Matters

Federal safety data shows crash risk is highest in a teen’s first year of independent driving. Night driving, teen passengers and distracted driving increase that risk – while seat belts, graduated licensing laws and supervised practice significantly reduce it.

In 2023, more than 2,800 teens ages 13-19 were killed in motor vehicle crashes nationwide, according to the CDC. However, teen crash rates have declined over time thanks to safer vehicles, graduated driver licensing programs and greater awareness of distracted driving.

Ways to Reduce Teen Driving Risk

The experts at Mercury Insurance encourage families to focus on preparation rather than panic.

1. Coach Early and Often

  • Log supervised driving time in different conditions – highways, rain, nighttime
  • Create a simple written driving agreement outlining expectations
  • Limit teen passengers during the first year
  • Make seatbelts non-negotiable

2. Let Technology Help

  • Choose vehicles with safety features like automatic emergency braking and blind-spot monitoring
  • Use telematics or safe-driving feedback tools to reinforce good habits
  • Activate smartphone “Do Not Disturb While Driving” settings

3. Review Insurance Before the Keys Change Hands

  • Add teens to your insurance policy promptly
  • Revisit liability limits to protect family assets
  • Ask about good student and driver training discounts

“Insurance is about preparation, not fear,” Irace said. “When families combine active coaching with the right coverage, they’re setting their teen up for safer miles ahead.”

Preparation Turns Risks into Confidence

The first solo drive is a milestone, but preparation determines what comes next. By pairing common-sense coaching with today’s vehicle safety technology and thoughtful insurance planning, families can support independence while managing risk responsibly.

Building a Birdhouse: A Step-by-Step DIY Process

Published

Building a Birdhouse: A Step-by-Step DIY Process

(Feature Impact) To add charm to your yard, encourage local wildlife and give you a front-row seat to nature, building a birdhouse is a simple weekend project that checks all of those boxes.

Building a Birdhouse

Seasoned DIYers and first-timers alike can follow this step-by-step guide to create a functional, welcoming birdhouse.

Step 1: Choose the Right Design
Start by deciding what type of birds you’d like to attract. Different birds prefer different house sizes and entrance types. A simple, classic birdhouse design makes the project beginner-friendly and works well for common backyard birds like wrens, chickadees and bluebirds. In general, plan for at least a 1-1 2/2-inch entrance hole, a 5-by-5-inch interior space and 2 inches or more of roof overhang.

Step 2: Gather Materials and Tools
Most DIY birdhouses can be built with basic materials and tools you may already have at home, including untreated cedar or pine wood, screws or nails, wood glue, sandpaper and exterior-safe paint as well as a measuring tape, pencil, saw and drill.

Step 3: Measure and Cut Wood
Measure and cut wood to make the front panel, back panel, two side panels, floor and roof. Then sand all edges for smooth assembly.

Step 4: Drill Holes
Using a hole-saw bit, drill the entrance hole into the front panel. Position it a few inches below the roofline to keep predators out. Next, drill 2-3 small drainage holes in the floor piece to prevent water buildup and help keep the birdhouse dry.

Step 5: Assemble the Birdhouse
Attach the side panels to the back panel using screws or nails. Add the front panel then secure the floor piece, slightly recessed, so rainwater can drain. Attach the roof last, making sure it slopes slightly to allow water to run off.

Step 6: Paint the Exterior
If you plan to paint your birdhouse, stick to neutral, nature-inspired colors. Light browns, soft greens or white help regulate temperature and blend into the environment.

Step 7: Mount Your Birdhouse
Once dry, place your birdhouse in a quiet, sheltered spot away from heavy foot traffic. Mount or hang it 5-10 feet off the ground, facing away from prevailing winds.
