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.


Nutrition, exercise, and health information can be confusing. 
But it doesn't have to be that way.
