The UK may not be known for extreme heat, but summer temperatures can sometimes rise high enough to cause serious health problems. For many Africans living in the UK, especially older adults, young children, and people with existing health conditions, understanding the warning signs of heat-related illness can help prevent emergencies.
At Naija UK Connect, we encourage our community to stay informed and stay safe during periods of hot weather.
Heat Exhaustion vs Heatstroke: What’s the Difference?
Heat Exhaustion
Heat exhaustion happens when the body becomes too hot and struggles to cool itself effectively. While it is usually not life-threatening, it can become dangerous if left untreated.
Common symptoms include:
- Excessive sweating
- Headache
- Dizziness or feeling faint
- Confusion
- Nausea or loss of appetite
- Muscle cramps in the arms, legs, or stomach
- Fast heartbeat or rapid breathing
- High temperature (38°C or above)
- Extreme thirst
Young children may become unusually sleepy, weak, or less active than normal.
Heat exhaustion can affect anyone, even healthy individuals, particularly after exercising in hot weather, spending long hours in the sun, or becoming dehydrated.
When Heat Exhaustion Becomes Heatstroke
Heatstroke is a medical emergency that requires immediate attention. It occurs when the body’s temperature rises to dangerous levels and can no longer regulate heat effectively.
Warning Signs of Heatstroke
Seek urgent medical help if someone:
- Still feels unwell after 30 minutes of resting in a cool place and drinking water
- Stops sweating despite feeling very hot
- Has a body temperature of 40°C or higher
- Experiences shortness of breath or very rapid breathing
- Appears confused or disoriented
- Has a seizure
- Becomes unconscious
- Is unresponsive
If you notice these symptoms, call 999 immediately.
How to Help Someone with Heat Exhaustion
If you suspect someone has heat exhaustion:
1. Move Them to a Cool Place
Take them indoors to an air-conditioned room or a shaded area away from direct sunlight.
2. Remove Excess Clothing
Loosen or remove unnecessary clothing to help the body release heat.
3. Cool Their Skin
Use any available cooling methods, such as:
- A cool, wet cloth or sponge
- Spraying water on the skin
- Cold packs on the neck and underarms
- Wrapping them in a cool, damp sheet
4. Encourage Fluids
Offer water, sports drinks, or oral rehydration solutions to help replace lost fluids.
5. Stay with Them
Monitor their condition closely and ensure they begin to recover.
Most people with heat exhaustion should feel noticeably better within 30 minutes.
Practical Tips for Africans Living in the UK During Hot Weather
- Drink water regularly, even if you don’t feel thirsty.
- Avoid spending long periods in direct sunlight, especially between 11am and 3pm.
- Wear light, loose-fitting clothing.
- Keep homes cool by closing curtains during the hottest parts of the day.
- Check on elderly relatives, neighbours, and vulnerable community members.
- Never leave children or pets in parked vehicles.
Stay Safe This Summer
Hot weather can affect anyone, regardless of age or fitness level. Knowing the difference between heat exhaustion and heatstroke could help save a life.
If symptoms do not improve within 30 minutes, or if you suspect heatstroke, call 999 immediately and seek emergency medical assistance.
