Winter isn’t over yet, so here’s a reminder: You can get dehydrated in cold weather. And it isn’t always easy to hydrate, especially when you’re on a mission. If you’re active outside for less than 2 hours, it isn’t likely to be a problem. But if you’re out in the cold for hours or even days for a field deployment, the combination of heavy clothing and high-intensity exercise can lead to sweating, which contributes to dehydration.
You might not even feel as thirsty in cold weather as in the heat, because your cold-weather body chemistry could affect your brain’s ability to tell you when you need liquid. Cold weather also tends to move body fluids from your extremities to your core, increasing your urine output and adding to dehydration.
So when you’re in a cold climate, don’t rely on thirst to tell you when you need to drink. Drink often and before you’re thirsty. One way to determine your hydration status is to check the color and volume of your urine. (Snow makes a good test spot.) Dark, scanty urine indicates dehydration. Ideally, urine should be light yellow.
Water and sports drinks are the best fluids to maintain hydration, even in cold weather conditions. Carbonated and caffeinated beverages (including energy drinks) have a dehydrating effect because they increase urine flow. Also avoid consuming alcohol in cold weather. It might make you feel warm initially, but it can reduce your body’s ability to retain heat.
Enjoy exercising in the cold weather, but be sure to keep your water bottle in tow.
Personal trainers can help you safely start and maintain an exercise routine. They can keep you motivated and accountable when it comes to reaching your fitness goals. Finding the right trainer can be challenging but important. Think of it like a date: get to know your potential trainer to find out if you’re compatible. Here are a few things to look for:
- Education/Certifications. These days, anyone can become a personal trainer with a few mouse clicks. Is this person certified through one of the National Commission for Certifying Agencies (NCCA) such as National Federation of Personal Trainers (NFPT), American Council on Exercise (ACE), American College of Sports Medicine (ACSM), or National Academy of Sports Medicine (NASM)? These are widely accepted certifications. Better yet, does the trainer have a 4-year degree in kinesiology or exercise science? Is he/she certified in CPR and first aid?
- Experience. We all have to start somewhere, but experience is helpful. How long has this person been a certified personal trainer? What types of clients does the trainer usually work with? Does he/she have expertise in sports conditioning, pre-natal fitness, or post-rehabilitation? If possible, ask clients (past and/or present) about their personal experiences.
- Personality. You have to enjoy spending time with your trainer so that you’re fully committed to your training routine. Do you prefer a female or a male trainer? Someone close to your age? Choose somebody you like—someone who can motivate you.
- Business practices/Liability. Before you begin, make sure you understand all payment policies and procedures. Are your schedules compatible? What’s the cancellation policy? Does the trainer carry professional liability insurance?
- Fees. Personal trainers can be worth the money, but make sure you understand what you’re paying for. What are the costs? How long is each session? How often will you meet? Is it cheaper if you buy more sessions up front? Will you need to purchase a gym membership?
Is it safe to exercise when you’re sick? Those who have strict workout schedules aren’t likely to let the sniffles get in the way of their physical fitness. Exercise benefits include better weight control, improved mood, more energy, and healthier sleep. What’s more, just 30 minutes of regular exercise 5 times each week can improve your heart health and boost your immune system too.
Moderately exercising while you’re sick can be safe and, in certain cases, might actually improve symptoms such as congestion and low-energy. First, you need to determine “how sick is sick.” You can figure this out by using the “neck rule.” If you have symptoms above the neck—including sore throat, nasal congestion, sneezing, or watery eyes—then moderate workouts can continue. If your symptoms are below the neck—including cough, fever, fatigue, or body aches—then rest until the symptoms are gone. You can also use your temperature to determine whether exercising is okay. If you have a temperature of 101°F or higher, moderate or vigorous exercise isn’t safe due to risks of heat-related illnesses and dehydration.
Ultimately, the decision to exercise when you’re sick is up to you. If you’re too weak and fatigued to get out of bed, exercising might not be the best choice. If you have symptoms of a cold and your temperature is below 101°F, light to moderate exercise could be good for you. Make sure to see a doctor if your symptoms don’t improve or get worse.
How you treat your heart today can add years to your life—that’s the best gift you can ever give your loved ones! The latest research continues to show that eating a balanced diet with plenty of fruits, vegetables, beans, nuts, seeds, whole grains, and minimally processed foods is good for your heart. Reflect on what you eat as this can dramatically reduce your risk of heart disease. Make sure to include these heart-healthy foods in your nutrition plan too: luscious berries, leafy greens, a variety of nuts, and seafood (twice per week).
Want to show some love for your sweetheart this Valentine’s Day? Cards, flowers, and chocolate are ordinary—do something extraordinary!
- Surprise your sweetie with a fabulous meal. If you’re able, dine in this Valentine’s Day. Make a delicious spinach salad and salmon with a nut topping. Serve berries, frozen yogurt, and Chocolaty Delights (see recipe below) for the perfect dessert. You’ll save money, eat like royalty, and provide the nutrients your bodies crave. Don’t forget the candles and your favorite playlist!
- Whip up Chocolaty Delights. Use cooking spray to grease the bottom of an 8 in pan. Blend one can of black beans (drained) and ¾ c water in a blender for 30 seconds. Add one box of brownie mix. Stir mixture well and spread in pan. Sprinkle ¼ c dark chocolate chips and ¼ c chopped walnuts on top. Bake according to box directions or until a toothpick (inserted in the center) comes out clean. Let your partner know that each tasty treat includes added protein, fiber, and iron—go ahead and indulge!
- Give a gift of lasting health. Consider a fitness app, pedometer, or walking shoes. Then invite your sweetheart to work out or take a long walk together.
Don’t let cold weather freeze your exercise routine. Use these tips to stay motivated, safe, and warm.
- Dress in layers. Choose synthetic materials such as polyester or polypropylene that stay close to the skin. Avoid cotton since it soaks up sweat! You can always remove layers as you get warmer.
- Protect your extremities—especially your fingers, toes, and ears. Circulation to these areas decreases in cold weather.
- Check the forecast. Wind chill, snow, and rain can make your body more vulnerable to the outside temperatures. Plan an indoor workout when the wind chill is extreme or the temperature drops below 0°F.
- Apply sunblock. You can still get sunburned in the winter so don’t forget the sunscreen!
- Stay hydrated. When exercising in cold climates, don’t rely on thirst to indicate hydration since you usually don’t feel as thirsty in cold temperatures. You need to stay just as hydrated in cold weather as you do when it’s hot outside.
- Ask your doctor. Certain symptoms might worsen in cold weather if you have asthma, heart issues, or Raynaud’s disease (when specific body parts feel numb due to to cold temperatures or stress). Talk to a healthcare professional about your concerns before heading outside for your cold-weather workout.

Little things you do during your workday can reduce the amount of time you sit, decreasing your chance of developing certain sicknesses. Many jobs involve hours of sitting. Commuting, sitting down for dinner and TV after work, and then sleeping only add to the time most people sit or lie down in their daily lives. The more time you spend sitting, the higher your risk of chronic illnesses such as heart disease, diabetes, and even some cancers. We offer some ways to move more throughout your workday.

Running is one of the simplest forms of exercise—just throw on your shoes and head out the door. But there are a few simple things you can do to ensure your run is safe too:
- Carry identification. Bring some form of identification with you. There are various types of wristbands and shoe tags to provide emergency contact and medical information too.
- Stay visible. Wear a headlamp and/or reflective gear so drivers can see you when it’s dark out—even at dusk and dawn. Make yourself visible to oncoming traffic.
- Turn the music down. Music can be a great way to help you keep pace. But if your tunes are too loud, you may not be able to hear cars or people coming up behind you. Keep music at a volume low enough that you can hear what’s going on around you, or try wearing just one earpiece when you run.
- Grab a buddy. Running with a friend is a great way to keep both of you motivated and accountable. But when you do run alone, let someone know and share your planned route.
- Use the crosswalk and follow crossing signs. Drivers tend to be more aware of pedestrians near crosswalks because in many areas pedestrians (runners included) have the right-of-way there. If you’re running where there is a crosswalk, use it.
- Don’t assume a car will stop just because you’re in a crosswalk. Make sure the driver sees you, slows down, and allows you to safely cross the street.
- Run against street traffic. Sometimes it’s easier to run on the shoulder or in a bike lane. Remember to run against traffic (normally the left side of the road) so you can see the cars and the drivers can see you.
Stay safe and happy running!
Feeling stuck in your workout routine? Periodization is a training method that can help you overcome the plateau and boredom from doing the same workout repeatedly. For example, if you follow the same lifting routine for too long, your body will eventually adapt to the stresses of training, and you’ll see little or no improvement in performance. Following a workout routine for “too long” depends on factors such as your age, training program, duration, intensity, and recovery. In order to see improvement, researchers suggest adding a periodization plan to your workout. Periodization works by changing different variables of a fitness routine (such as the amount of weight, number of repetitions or sets, or intensity) every 1–6 weeks. Changing components of your workout forces your body to constantly try to overcome the new stresses and encourages continual growth and increased performance.
Creating a periodization plan also reduces your risk of overtraining. Consult a certified trainer to design a program that can help you overcome any workout plateaus, or check out the Navy Operational Fitness and Fueling System (NOFFS) strength and endurance training series.
Thanksgiving is a day of full hearts and full bellies, but consider starting your day off right with a little burn. Calorie burn that is. Pretty much wherever you are, you can find a road race (also popularly known as a “turkey trot”), and most are family friendly. A morning race can be a great way to burn some extra calories before you gobble down your afternoon feast. If you’re not up for the race crowds, find a quiet road for yourself, go for bike ride, or enjoy some fall foliage on a hike. Whatever floats your gravy boat. Happy Thanksgiving, and thank you to all of our service men and women and their families.
