Stay Fit, Stay Safe: Exercising in the Summer
In the summer, we lose so much fluid so it is important to replace lost fluids with electrolytes -- liquids containing sodium, magnesium and potassium.— Joy von Werder, USAT triathlon coach and owner of Train to Tri coaching
The heat of the sun can be
merciless during warmer months, especially for those who like to
exercise outdoors. Whether you're a cyclist who hammers out hours in the
saddle or just someone who enjoys a morning jog or an occasional boot
camp, there are safety precautions you should keep in mind when
exercising outdoors in high temperatures. Heat stresses the body and
causes responses that could be dangerous when left untreated. Keep your
body cool and your workouts safe by being mindful of a few factors, such
as exercise times, nutrition, hydration and clothing.
Your Body's Response To Heat
Your core temperature rises when
you exercise in the heat, and your body responds with its natural
cooling mechanism: sweat. As sweat evaporates from your skin, it helps
to reduce your body temperature. However, prolonged exposure to the heat
can result in excessive sweating and dehydration, which in turn can
cause you to develop heat-related illnesses such as heat exhaustion,
heat cramps, and the most dangerous -- heat stroke. Fortunately, there
are several preventative measures that you can take to avoid getting
sick in the sun.
What Should You Drink?
Sports drinks are meant to aid in hydration and replace vital nutrients lost during intense exercise. If you're just going for a morning jog or doing a moderate workout in the gym, water is fine. However, for workouts lasting more than an hour or taking place in extreme heat, a sports beverage will help your body replace sodium and electrolytes lost through excessive sweating. Sports drinks may also help prevent dehydration because they're more flavorful -- many people are more likely to keep on sipping a sports drink than plain water because it's tastier.Pay Attention to Additonal Hydration and Nutritional Needs
The single most important
element to safely exercising in the heat is hydration. When you're
planning to train in heat, take a preemptive strike against dehydration
by beginning to consume water an hour or two before your workout begins.
During exercise, strive to drink about seven to 10 ounces of liquid
every 15 to 20 minutes. Joy von Werder, Florida-based USAT triathlon
coach and owner of Train to Tri coaching, is very familar with the
brutality of outdoor training in hot conditions. "In the summer, we lose
so much fluid so it is important to replace lost fluids with
electrolytes -- liquids containing sodium, magnesium and potassium,"
recommends von Werder. Your nutritional needs also increase during
workouts, especially in the heat. Vitamins play a critical role in
energy production, and since they're often lost through excessive
sweating, it may be a good idea for those who regularly train in hot
temperatures to supplement with a multivitamin.
Wear Clothing Designed For Exercise in the Heat
Working out in a cotton t-shirt
is a thing of the past. These days, the market is flooded with high-tech
clothing and fabrics to help you stay cool in the heat. Wear
lightweight, light-colored clothes made of sweat-wicking materials like
CoolMax, Drymax or Smartwool, to keep from becoming a hot, soggy mess.
Remember, sweat cools your body as it evaporates from your skin, so
clothing that keeps sweat trapped on your body will interfere with this
natural cooling mechanism. There are also special materials available
that block a portion of the sun's harmful UV rays which can lead to
sunburn and overheating. These fabrics are rated by an Ultraviolet
Protection Factor (UPF). Like SPF in sunscreen, UPF measures the degree
to which fabric disrupts UV rays, ranging from 15 (good) to 50+
(excellent). Although these fabrics can help prevent sunburn, it is
still very important to wear and reapply a sweat-proof sunscreen every
90 minutes, suggests von Werder.
Acclimate to Hot Environments
To prevent overheating
outside, give your body the chance to adapt to hot environments. If you
live in a cool, dry region, the heat and humidity of other areas will
come as a shock to your system. Ease into training in these environments
over a couple of weeks by slowly increasing your exercise intensity and
duration. When possible, save your highest intensity training for
cooler months. For example, if you're planning to run a marathon, choose
a race in early summer or winter. This will allow you to complete your
hardest training in the cooler spring and fall months.
Create a Backup Plan
On days when the heat is just
too much for your planned workout, have a backup plan that either
shortens your workout or takes it inside. When the heat is too intense,
"some people prefer to exercise indoors and take part in an indoor
cycling or spinning class, or swim," says Von Werder. Working out
indoors may seem boring, but you'll be able to train harder and longer
without putting yourself at risk for developing heat-related illnesses.
Finally, make sure you discuss your medical risks with your doctor. If
you have a condition that leaves you prone to overheating, plan your
workouts accordingly.
