It’s time for summer camping! However, during hot summer weather, it’s important to know the symptoms of heat stroke.
Heat stroke will develop with prolonged exposure to the heat, and generally happens along with dehydration. It can happen while summer camping, or while stuck in traffic without air conditioning. Heat stroke occurs when the body’s core temperature exceeds 104 degrees Fahrenheit. This will cause the body’s temperature regulation to fail. Consequently, this causes damage to the internal organs and brain. Heat stroke is life threatening, and if you or someone else has signs of heat stroke, call 911 immediately.
The 5 Main Signs of Heat Stroke
Heat stroke causes dizziness and possibly fainting, because the blood flow is quickly reduced to the brain. This is because extreme hot weather can cause increased blood flowing to the extremities and skin. This causes blood to collect in the legs, causing a sudden drop in blood pressure. If you have any feelings of light headedness or dizziness, get out of the sun and re-hydrate before you can faint.
Dehydration can cause a headache or even a migraine. During hot weather, you need more water to compensate for increased perspiration. If you spend time in the sun and develop a headache, heat stroke is a possiblity. Other things that can contribute to a heat related headache are the glaring sun and a sudden change in barometric pressure. If you develop a dull, throbbing headache, sensitivity to light and fatigue, get out of the sun right away. Drink lots of water, or a sports drink with electrolytes.
Dehydration as well as heat headaches can cause nausea. Nausea can lead to vomiting, which will worsen dehydration. Bright, glaring sunlight can also lead to nausea and vomiting. When the body perspires and becomes depleted of salt and electolytes, nausea also can happen. If you experience nausea while in the sun, find some shade, and drink an electrolyte drink, and eat a salty snack
When the body becomes over heated, then tries to cool down, the heart is under an increased level of strain. This in turn causes an increased the heart rate. When the weather is hot, up to four times the blood may be pumped every minute, as opposed to cool weather. This causes the heart to beat much faster and harder. If you experience a rapid heart beat during hot weather, find some shade and cool off with a fan.
Heat cramps can be an early sign of heat stroke. Heat related cramps are felt as spasms in the large muscles. These spasms are also accompanied by profuse sweating. These cramps occur in the large muscles groups, such as the legs if you are walking or running. Muscle cramps can also happen in the core muscles of the back and abdomen, as well as in the arms. Muscle cramps may also occur hours after activity. Dehydration and electrolyte depletion are related to these muscle cramps. However, when muscles become tired from over work, they can lose the ability to regulate contraction.
The best way to avoid heat stroke and the related symptoms, is to avoid exercise and over exposure under the hot sun.
