Health Tips for Hot Weather
Heat and humidity describe the summers of southeast Missouri.
Has this combination of weather conditions ever left you
feeling tired, headachy, nauseated or faint?
If so, you probably have experienced heat exhaustion.
Over exposure to heat can produce a range of effects from a
simple skin rash to a potentially deadly “heat stroke”.
Heat exhaustion is one step short of a “heat stroke” or
“sun stroke” and it may occur indoors as well.
These are not strokes as in the usual brain attacks involving
loss of blood flow to or bleeding within the brain.
Although, “heat or sun strokes” may cause brain injury when
body temperature exceeds 105-106 F.
Summer is a time of outdoor activity.
Whether you are playing softball in the park or building that
deck that you have long waited for, your activity indoors and outdoors
must be balanced with your body’s ability to cool itself or you will
develop heat exhaustion and ultimately heat stroke. There are a variety of conditions that limit our body’s
ability to cool itself. Old
age, obesity, illness with fever, dehydration, heart disease, poor
circulation, sunburn, medications and alcohol use can impair normal
body temperature regulation. Sweating
and the evaporation of sweat is a cooling mechanism. High humidity can
reduce the rate of sweat evaporation, which may effectively reduce our
body’s natural ability to cool itself.
Each year summer heat waves bring unusually high temperatures
that put people at risk for heat-related illness or death. However,
early recognition of the signs and symptoms of heat prostration and
swift treatment can often prevent serious consequences.
Symptoms of heat stroke include lethargy, confusion, stupor,
agitation, rapid pulse, hot and dry skin and sometimes loss of
consciousness.
Follow these
first-aid steps:
*Call 911
*Get
the person out of the sun
*Remove
clothing and sponge with cold water
*Fan
the person and continue with cold water application until emergency
medical assistance arrives or until body temperature is less that 101
degrees.
Don’t even wait for the signs of heat exhaustion to appear.
Drink water before, during and after physical activity.
Don’t wait for thirst. Drink
5-8 oz of water every 20 minutes of heavy physical exertion. For
extended activity, drink one of the “sports drinks” that replaces
electrolytes. If you are
traveling or have just moved to the area, let your body get used to
the heat and humidity. It
takes about 10 days to get acclimated so exercise, work and play less
vigorously. Wear loose,
lightweight clothing that allows your body to breathe.
Wear cool shoes made of mesh or canvas that allow your feet to
breathe. If you are
exercising in the heat be sure to use at least a 10-15 minute “warm
up” and “cool down” period.
Avoid alcoholic beverages---they dehydrate your body.
Take frequent breaks from whatever activity you are doing in
the heat and most of all, listen to your body.
If you feel ill, light-headed, nauseated, headachy or fatigued
get out of the heat and cool down.
If your symptoms persist or worsen seek emergency medical
assistance.
