BEAT THE HEAT: Be prepared to tackle the scorching summer

Published: 03 Jul 2013 - 02:26 am | Last Updated: 31 Jan 2022 - 02:35 pm

About 40 cases of heat exhaustion were treated at the Emergency Department of Hamad Medical Corporation (HMC) in May this year. 

But from June through September, five to ten cases of heat exhaustion are expected daily for treatment at the Emergency Department. 

Senior Consultant at the Emergency Department of HMC, Dr Saad Abdulfattah Al Nuaimi, advises people to take precautions to prevent heat-related illnesses.

Dr Nuaimi says drinks containing caffeine or alcohol should be avoided, and so should be heavy meals. Leaving children and infants inside parked cars can be risky in summer as the temperature inside a vehicle standing in the sun can increase dangerously.

Also, people on a low-salt diet are advised to seek a doctor’s advice to maintain their mineral levels, especially while doing physical exercise. 

According to Dr Nuaimi, heat exhaustion is a common illness in summer. It occurs when the body’s temperature control system fails due to exposure to high temperatures (eg above 35؛C) and humidity. 

Symptoms of heat exhaustion include cramps, fatigue, weakness, headache, dizziness, nausea, and occasionally vomiting, but usually consciousness is retained. Body temperature might be between 38 and 39 degrees Celsius, says Dr Nuaimi.

A person suffering from heat exhaustion should be immediately moved to a cooler area, his clothes should be removed or loosened and a cool shower should be given, if possible. Plenty of cool drinks and some salty snacks, too, should be given.

People having mild heat exhaustion are advised to go to a Primary Health Center, while those with symptoms such as drowsiness or loss of consciousness need to be taken to the Emergency Department. Cases where symptoms persist more than an hour after first aid, or where the person has co-morbidities such as diabetes, hypertension or obesity, should also be taken to the Emergency Department.

Good habits to follow during summer 

 

• Increase fluid intake to stay hydrated and replenish the water your body loses due to excessive sweating. 

• Avoid drinks containing caffeine or alcohol, as these can cause you to lose more body fluids.

• Eat small snacks throughout the day. Avoid heavy meals and hot food as these can increase body temperature. Salty snacks and fruit juices can help replenish salts and minerals lost through excessive sweating. If you have a chronic illness and are already on a low-salt diet, however, you will need to consult your doctor regarding the amount of salt you can safely consume.

• Stay indoors in a cool place as much as possible. Avoid going out between 10am and 3pm as the temperature is usually at its peak during this time. Schedule outdoor activities such as sports in the early morning or evening hours when it is cooler.

• If you need to go outdoors, it is best to stay or rest often in shady areas. Wear a hat, sunglasses and sunscreen of SPF 15 or higher, applied about 30 minutes before exposure to the sun. 

• Wear lightweight, light-colored, loose-fitting clothing. 

• Having someone accompany you is also advised when you have to stay or work in a hot environment. Heat-related illness can sometimes progress so rapidly that you may suddenly become drowsy or unconscious, so it is helpful to have someone around who is aware of the situation. 

• During exercise, drink two to four glasses of water or other cool, non-alcoholic fluids per hour. If you exercise outdoors, start slowly to allow your body to acclimatise to the hot weather. If you start having a fast or strong heartbeat and are feeling tired, stop exercising for that day, rest in the shade and take plenty of fluids. 

• Never leave infants, children or pets unattended in a parked car, as temperatures can rise rapidly inside the vehicle.

• Check frequently on people at greater risk of suffering from heat-related illness, such as the elderly, young children and babies, and those who are obese or have chronic illnesses such as diabetes, hypertension or other co-morbidities.
 

Heat-related illnesses: Symptoms and first aid 

(Suggested by the Hamad Medical Corporation) 
Heat cramps are muscle pains and spasms caused by exposure to high heat and humidity, resulting in loss of fluids and electrolytes. Adequate intake of fluids and salty snacks can help prevent heat cramps.
What to do If you suspect heat cramps, stop all activity in the hot environment. Rest in a cool, shaded area and take plenty of cool drinks.
 
Heat syncope usually happens to those who exercise or stand for a long time in a hot environment, becoming dehydrated and developing a fainting attack. 
What to do: Move the person to a cooler, shaded area; make the patient lie down and slowly drink an adequate amount of fluids. If symptoms persist, the person should be immediately brought to the Emergency Department.
 
Heatstroke (or sunstroke) is the extreme stage of heat exhaustion which causes damage to the central nervous system. The person will have a very high body temperature, usually exceeding 40 degrees Celsius, increased pulse rate, headache, dizziness and nausea, and may also sometimes suffer convulsions or go into a coma. If not treated early, heatstroke can rapidly lead to death.
What to do: First-aid treatment is the same as that for heat exhaustion, but the person should immediately be transported to the Emergency Department. If the person has nausea or is vomiting, make him lie in a lateral position (on one side) so he can expel the vomit and avoid aspirating it into his respiratory tract. If he has convulsions, make sure he is away from things that could cause injury, such as fire or electricity.
 
Heat rash occurs when sweat glands or ducts become obstructed due to excessive sweating, resulting in red pimples or blisters which usually affect the neck, upper chest, the area below the breast, in the armpit, in the elbow, and in the groin. 
What to do Avoid further exposure to heat and humidity. Keep the affected area dry and apply dusting powder. Avoid any ointments or creams, which can further block the sweat glands and worsen the condition. 
 
Sunburn is usually a first-degree burn which causes some redness and pain in the skin. 
What to do Sunburn is best prevented and healed by avoiding exposure to the sun, especially for fair-skinned people, and using sun creams. If the sunburn becomes very painful and blisters appear, seek medical advice.
