Metro warns about coming high temperatures

WEB HEADLINE: Metro warns residents against these summer risks

Summer in the Southern atmosphere is almost here. Most of us welcome the hot weather, but it can bring detrimental effects to life in both plants and animal kingdoms, including humans.

Some places can be hit by heatwaves and endure a prolonged and persistent period of abnormal hot weather posing serious health risks to life and potential summer fire hazards.

City of Ekurhuleni Disaster and Emergency Management Services (DEMS) would like to send a cautionary alert to the people not to overlook the risks that come with the hot temperatures until it’s too late.

The main risks that a heatwave poses to life are:

• Dehydration

• Overheating

• Heat exhaustion

• Heat stroke.

Dehydration describes a deficit of total body water, with an accompanying disruption of metabolic processes.

Dehydration occurs when free water loss exceeds free water intake, usually due to exercise, disease, or high environmental temperature.

The most common warning signs and symptoms of dehydration include:

• Dry skin

• Dry mouth, as an early sign

• Sleepiness

• Thirst, as an early sign

• Decreased urination

• Muscle weakness

• Fatigue

• Headaches.Treatment of dehydration:

• Rest the affected person under the shade, dress lightly and brighter colours.

• Help them to sit down and give them plenty of water to drink. Avoid providing carbonated drinks.

• Giving them an oral rehydration solution to drink will help replace salt and other minerals which they’ve lost – you can buy this in sachet form any pharmacy.

• If they have any painful cramps, encourage them to rest, help them stretch and massage their muscles that hurt.

• Keep checking how they’re feeling – if they still feel unwell once they’re rehydrated then encourage them to see a doctor straight away.

Heat exhaustion is a condition which symptoms may include heavy sweating and a rapid pulse, a result of body overheating.

It’s one of three heat-related syndromes, with heat cramps being the mildest and heatstroke being the most severe.

Common signs and symptoms include the following:

• Confusion.

• Dark coloured urine.

• Dizziness

• Fainting.

• Fatigue.

• Headaches.

• Muscular or abdominal cramps

• Nausea and vomiting or diarrhoea.

• Pale skin

• Sweating profusely

• Rapid pulse rate.

Treatment of heat exhaustion:

• It is essential to get out of the hot environment and rest; preferably in an air-conditioned room or shady place.

• Drink plenty of fluids, especially sports drinks to replace lost salt. Avoid caffeine and alcoholic drinks.

• Remove any tight or unnecessary clothing.

• Take a cool shower, bath or sponge bath.

• Apply other cooling measures such as fans and towels.

If such measures fail within 15 minutes, seek emergency medical interventions because untreated heat exhaustion can lead to heat stroke.

Heat stroke: Heat stroke, also known as sun stroke, is a type of severe heat illness that results in a body temperature greater than 40°C.

Signs and symptoms of heat stroke:

• Dizziness or light headedness.

• Seizures or coma.

• Nausea and vomiting.

• Flushed and reddened skin.

• Slurred speech.

• Agitation.

• Disorientation.

• Delirium.

• Unconsciousness.

Heat sroke is a serious medical condition that can lead to organ failure and even death.

Treatment of heat stroke:

• Prompt cooling will bring core body and brain temperature back to normality within an hour. Do cold water immersion.

• Seek prompt medical intervention as soon as possible.
