Heat Illness Could Be Closer Than You Think

Heat Illness is a general term that covers a range of conditions, including heat cramps, heat exhaustion, and heatstroke. As the temperatures rise this summer, this common affliction could become a serious threat if ignored or underestimated.

In this brief post, we’ll help you to Spot the signs early and how to act fast.

Whether your team works outdoors, in a hot warehouse, or can't avoid wearing heavy PPE, here's what everyone should know:

1: Heat Cramps

What it looks like:

• Painful muscle cramps or spasms (usually in legs or abdomen)
• Heavy sweating during intense activity

What to do:
Move the person to a cool place, encourage them to drink fluids containing electrolytes like sports drinks or a solution of water with salt (1 teaspoon per litre), and gently stretch and massage the affected muscles. 

If cramps persist for more than a few minutes, are severe, or don't improve with self-care, seek medical advice. 

2: Heat Exhaustion

This is your warning sign. If ignored, it can lead to heat stroke.

Symptoms to watch for:

• Headache
• Dizziness or light-headedness
• Nausea or vomiting
• Weakness, fatigue
• Heavy sweating, cool or clammy skin
• Fast, weak pulse

What to do:
Immediately move the person to a cool place, preferably indoors with air conditioning, or at least into the shade. Encourage them to rest, lie down, and elevate their legs. 

Offer them cool water or an electrolyte drink to sip on. Apply a cool, wet cloth or spray them with cool water and fan them. If symptoms worsen or don't improve within 30 minutes call emergency services. 

Don't ignore it. Heat exhaustion can escalate quickly if not treated.

3: Heat Stroke - Medical Emergency

This is life-threatening. Immediate action can save a life.

Critical signs:

• Confusion, slurred speech
• Seizures or unconsciousness
• Body temperature above 103°F (39.4°C)
• Skin is hot, dry, or severely flushed (sweating may stop)
• Rapid, strong pulse

What to do:
Call 999 immediately. Move the person to a cool area and try to lower their body temp with ice packs, wet towels, or fans. DO NOT give fluids if they’re unconscious or confused.

What Employers Should Do

• Train your team to recognise symptoms in themselves and others
• Set up a buddy system on hot days
• Ensure easy access to water, shade, and rest breaks
• Have a plan in place to respond to heat emergencies

The Bottom Line:

Heat illness doesn’t just happen to “other people.” It can sneak up on anyone - even the fittest worker - especially when hydration and rest fall behind. When your team knows what to look for, they’re empowered to act fast, help each other, and stay safe.

Stay alert. Stay informed. Stay safe.
