Summer
is a great time for being active. Even if you live where it gets hot or
humid, there are ways you can stay in shape year-round. But make sure
to take precautions when you are active outside.
Be safe in the heat
If the temperature is lower than
80 F (27 C),
you usually can be active outside without taking extra precautions. It
depends on how active you already are and how used to hot weather you
are.
But anytime you exercise, it's a good idea to take these normal precautions:
- Drink plenty of water. This is very important when it's hot out and when you do intense exercise.
- Don't exercise as hard when it's hot. Take rest breaks. Exercise more slowly than usual or for a shorter time.
- Stay in the shade when you can.
- Avoid exercising during the hottest times of the day.
- Wear light-colored, breathable clothes.
- Watch for signs of heat exhaustion, such as nausea, dizziness, cramps, and headache. If you notice any signs, stop your activity right away, cool off, and drink fluids.
When the temperature gets above
80 F (27 C),
consider the heat and the humidity. Both can put you at risk for
heat-related illness. The hotter or more humid it is, the higher your
risk. For example, if the humidity is 60% (moderate):
- Be careful when you exercise in temperatures of 80 F (27 C) to 85 F (29 C). Find shade, take regular breaks, and drink plenty of fluids.
- Experts advise being extremely careful between about 85 F (29 C) and 91 F (32.8 C).
- Conditions are considered extremely dangerous at temperatures over 91 F (32.8 C).
When it is more humid, you should be careful at even lower
temperatures. Higher humidity can make it feel hotter, since your body
cannot cool off as well by
sweating.
This puts you at a greater risk for illness. For more information, see
the website www.nws.noaa.gov and search for "heat index."
Older adults and children are at a higher risk for heat-related
illness and should be extra cautious. Remind children to drink plenty
of fluids before, during, and after activity.
If you are
overweight,
have health problems, take medicines, or use alcohol, you may be at a
higher risk for heat-related illness. You may also have trouble if
you're not used to exercising in warmer weather.
In hot weather, drink plenty of fluids before, during, and
after activity. Water or sports drinks are best. This helps to prevent
dehydration
and heat-related illness. Water is all you need if you are exercising
for less than an hour. For longer exercise periods, sports drinks
contain carbohydrate and minerals called
electrolytes that may help your endurance and keep you from getting muscle cramps.
