FITT-SPF: How to exercise safely in the sun this summer.

People who exercise are probably familiar with FITT—frequency, intensity, time, and type—the basic principle behind almost all fitness programs. The FITT principle applies to everything from running to weightlifting to yoga. For people who exercise outdoors there are three more letters that are important to know, especially in the summer: SPF. This is the topic of my Health & Fitness column in the Aiken Standard this week.

First, a bit more about FITT. Exercise prescriptions are based on four key concepts that allow training to be tailored to meet individual goals. Frequency refers to how often you are training, usually expressed as days per week. Intensity is how hard you are working, which could be running or walking speed or the amount of weight you are lifting. Time is simply how long you are exercising per session. Type is the specific type of training you are doing, which we typically think of as endurance (like walking), resistance (lifting weights), or flexibility (stretching).

Keep in mind that there is interaction between these components. Less intense exercise like walking is typically done for longer than more intense exercise such as interval training can be done in shorter sessions. Some people focus on one type of training at a time, as in weight lifting to increase strength or yoga to enhance flexibility, while others do exercise that includes some endurance, resistance, and flexibility training in the same session. Many group exercise classes and programs like CrossFit are examples of combining multiple aspects of fitness in one session. Since everyone has a different starting fitness level and goals, FITT can be manipulated to meet a variety of needs.

Many types of exercise, especially endurance or aerobic training, can easily be done outdoors. Walking, running, cycling, and water sports like stand-up paddle boarding and kayaking, are popular outdoor activities, especially in the summer. Being active outdoors in nature improves health and wellbeing beyond the fitness benefits of the exercise itself, so “going green” with your workouts is a great idea! Some sun exposure is necessary for your body to produce vitamin D, an essential nutrient. But excessive sun exposure can increase the risk of skin cancer, the most commonly diagnosed form of cancer.

Excessive sun exposure is a real risk of exercising outdoors, especially for prolonged periods of time. Cycling, running, water sports, and skiing have been identified as sports that increase the risk of some types of skin cancer. Unfortunately, sunscreen use among outdoor athletes is low. According to survey results, at least half of college athletes never apply sunscreen before games and practices and those who report using sunscreen don’t use it regularly.

Marathoners, who can accumulate 1,000 or more hours of sun exposure during training per year, are more likely to be diagnosed with skin cancer than non-runners, but only about half use sunscreen, according to one study. Regular sunscreen use is even lower in the general population—about 30% of women and 15% of men—so even if you aren’t an athlete it is likely you are still at risk.

The good news is that there is much you can do to reduce your risk of skin cancer while you are active outdoors. First and foremost, properly applying (and reapplying every two hours) a broad-spectrum sunscreen with an SPF of 30 or higher is the best way to protect exposed skin. Some sunscreens are more water and sweat resistant, but still need to be reapplied regularly.

Second, covering exposed skin with light-colored clothing, a hat, and sunglasses is smart. Some clothing is more resistant to UV rays than others, so look for a higher ultraviolet protection factor (UPF). Obviously, you need to find a balance between protecting your skin and allowing sweat and heat loss to keep you cool.

Third, try to exercise outdoors in the early in the morning or later in the day when the sun’s rays are less direct. Keep in mind that you should still use sunscreen on cloudy days as UV rays can penetrate clouds. This also tends to be when temperatures are lower, too, so exercise may be more comfortable.

The bottom line is that summer is a great time to be active outdoors. By taking a few precautions you can do it safely, especially when it comes to reducing your risk of skin cancer from excessive sun exposure. You can learn more about skin cancer risk and prevention from the American Cancer Society and the American Academy of Dermatology.

It’s not too late to celebrate Walktober!

Walking is a great way to be active to help you lose weight, increase your fitness, and improve your health. The most common form of exercise is walking, and for good reason: it doesn’t require any special equipment (beyond comfortable shoes) or skills, and you can do it almost anywhere.

You can meet basic physical activity recommendations by walking briskly for 30 minutes most days of the week. Even this amount of walking can lead to a lower risk of diabetes, heart disease, and some cancers as well as improved mental health, cognitive function, and greater feelings of wellbeing.

Now that cooler fall weather is finally here, spending time being active outdoors is more enjoyable. That is the spirit of Walktober, an initiative adopted by health organizations, companies, and communities around the globe. October is a great time to take advantage of opportunities to go for a walk!

Walking, like any exercise, has substantial health benefits. These benefits are even greater if you are active outdoors. Being active in a natural environment has been shown to have an impact on mental health including enhanced feelings of energy and diminished fatigue, anxiety, anger, and sadness compared to similar activity conducted indoors. Research shows that exercise outdoors leads to physiological changes in brain blood flow that are associated with psychological benefits.

When you go for a walk outdoors you may get a better workout. This is mostly due to the fact that you will likely walk faster outdoors, but other factors like uneven ground and hills add to your effort. The good news is that even though you may exercise at a higher intensity outside, you may feel that your effort is lower than for the same exercise indoors. This is partly because the pleasant visual stimuli outdoors distracts you from sensations of effort during exercise. And much of the psychological benefit of outdoor exercise occurs in the first five minutes, so even short bouts of activity are meaningful.

If you are new to walking for exercise, you can start with 10–15 minute sessions and work up to 30 (or more!) minutes at a time. This can be as simple as going for a short walk outside when you have a break at work or taking your dog for a walk around the neighborhood. It’s also a good idea to walk with a friend or in a group, which can provide motivation and accountability. And, of course, it is a great way to spend time together.

If you have been exercising indoors, this is a perfect time to take your activity outdoors. Going for a hike in the woods or a long walk around town can build your endurance, especially if you encounter hills along the way. Running outdoors can break the monotony of the treadmill or other indoor exercise equipment. This might not replace your workouts at the gym, but it can certainly add to your activity.

The best part is that walking outdoors is something the whole family can do. Beyond the health benefits for everyone in your family, it sets an excellent example for your kids (and grandkids). Many experts agree that increasing opportunities for outdoor play and exercise is important for helping children grow up healthy and happy.

Every little bit of activity you do outdoors will have both physical and psychological benefits to help you become and feel healthier. So, get outside and get active this Walktober!

The heat is on! How to safely enjoy outdoor summer activities.

It’s that time of year again: school is out and the temperature and humidity are up. Since summer is officially underway it is a good time to revisit some common sense guidelines to make exercise, work, and play outdoors in the summer heat safe and enjoyable for your entire family. This is the topic of my Health & Fitness column of the Aiken Standard this week.

Water fight


Drink plenty of fluids

When it’s hot you have to sweat to lose heat and maintain your body temperature. High humidity makes sweating less effective, so you sweat even more. Losing lots of water through sweating can lead to dehydration. At the very least, you probably will feel fatigued but in more severe cases dizziness, low blood pressure, and fainting can occur.

For this reason it is important to drink plenty of fluids before, during and after your outdoor activity. As a general rule, a cup (8 oz.) of water every 15 minutes is sufficient for most people. Thirst is a good indicator of fluid needs, but you should take frequent breaks to rehydrate. You can see how dehydrated you are by weighing yourself before and after outdoor exercise. Every pound you lose is equivalent to 16 oz. of water you need to replace.

Make sure to remind kids to take breaks since they can get so busy playing that they forget. Water, juice, sports drinks, and other soft drinks are equally effective, so pick something you and your kids will drink.

Take breaks

The longer you are active the hotter you will get and you may feel more fatigued because of the heat. Taking frequent breaks will give you a chance to rest, cool down, and get something to drink.

Seek out shade

Being in the sun means that you will feel even hotter because you gain heat from the sun’s rays. Spending as much time as you can in the shade will help you stay cool. While this isn’t always practical for all activities, look for shady spots to take breaks.

Keep in mind that shady areas at will change throughout the day, so plan your trip to the park accordingly. Also be aware that direct sunlight can make outdoor surfaces, like playground equipment, very hot. This is another reason to find shady areas to play.

 

Pick cool clothes

Lighter colored clothing will reduce heat gain from the sun. Synthetic fabrics that wick sweat from the skin can help keep you feel cooler, too. And having more skin exposed will allow you to lose more heat.

Wear sunscreen

Sun exposure is the leading cause of skin cancer. Always use a broad-spectrum (both UVA and UVB rays) sunscreen and apply—and reapply—it according to the instructions. You should also protect your eyes by wearing a hat or sunglasses.

Avoid the hottest times of the day

Try to plan your outdoor activity in the morning or evening to avoid the hottest times of the day. Keep in mind that the highest temperatures often occur in the late afternoon or early evening, so right after work may not be the best time for outdoor activities. Early in the morning is probably the best time since it tends to be cooler and less humid.

You may not be able to plan all of your activities in the shade or when it is cooler. This is especially true for people who work outdoors. In these cases, drinking plenty of fluids and taking frequent breaks is particularly important. By taking the right precautions, though, you can still enjoy your favorite outdoor activities all summer long.

Your Park Prescription

Since Earth Day just passed you are probably thinking about ways you can “go green” to reduce your impact on the environment. Many of these choices are also good for your health. For example, choosing food from local farms is associated with fewer “food miles” and a lower environmental footprint. It is also likely to be picked at the peak of freshness, meaning it is richer in nutrients, not to mention flavor. Walking or biking instead of driving is another way to protect the environment while you protect your health.

When it comes to exercise, you can literally “go green.” Being active outdoors in nature leads to enhanced feelings of energy, improved mood, and diminished fatigue, anxiety, and anger compared to similar activity conducted indoors. Additionally, some research suggests that outdoor activity may improve attention and productivity in adults and children. Even though the physical, mental, and social benefits of activity in a natural environment are well established, most recommendations just focus on activity, not where it is done. Making the outdoors your destination for activities for you and your family is the topic of my Health & Fitness column in the Aiken Standard this week.

The National Park Prescription (Park Rx) Initiative is designed to encourage people to make the outdoors their destination for exercise and family activities. In fact, April 24th was National Park Rx Day. The idea is to promote access to and use of parks, trails, and other green spaces and highlight the health, environmental, social, and economic benefits of having these resources in our communities. The benefits of parks can be enjoyed by everyone, regardless of age or ability, so enhancing public lands should be a high priority.

This isn’t new of course, but it’s nice to have a reminder. At playgrounds you commonly see as many children playing in the trees that surround the swings, slides, and monkey bars as you see on the playground equipment. Grassy areas serve as picnic spots, impromptu sports fields, and places to run and play. Trails through the woods offer a place to hike and bike as well as trees to explore and climb. Lakes, rivers, and streams (called water trails) are perfect for rowing, paddling, and swimming. And many public parks and green spaces have paved trails so that people of all ages in strollers or wheelchairs can enjoy the outdoors.

Fortunately, there many excellent parks and natural areas to explore in the Aiken area. Aiken State Park, several county and city parks, and neighborhood playgrounds make it easy to find a place to be active outdoors. There is no better place to experience nature than the vast Hitchcock Woods, located right in the heart of Aiken. Community organizations like the GAIT Foundation are dedicated to expanding access to natural areas for all types of outdoor activates. This makes it easy to find a place to walk, run, bike, hike, climb, swim, paddle, push, or ride.

It also makes it easy to follow the Park Rx. Being active is one of the most important things you can do to improve your health and wellbeing. Activity in a natural environment has additional physical, mental, and social health benefits. Share these benefits with others by planning outdoor activities with your family and friends. For maximum effect, you should do this as often as possible—everyday is best. And it doesn’t need to be a day long excursion. Even taking the dog for a short walk, playing outside with the kids, or doing yard work are good ways to reap the benefits of being active outdoors.
