Most guides written for workers heading to Europe assume cold weather. Gloves, thermal layers, boots, the dark afternoons. That advice is right for a winter placement in northern Europe. It is close to useless if your work is seasonal agriculture in southern Romania in July, or a summer construction site where the temperature on the concrete is far higher than the temperature in the shade.
Heat is the risk that gets taken least seriously, because it does not look like a risk. There is no ice to slip on. There is no machinery to respect. There is just a long day and a strong sun, and the damage builds quietly across the afternoon rather than arriving as an accident.
This guide is about what to watch for, what to do before you travel, and what to do on a day when the heat starts to win.
Why heat is a real hazard and not a discomfort
The body cools itself by sweating, and sweating only works if you replace what you lose. When you are working physically in heat, you can lose a significant amount of fluid in an hour, along with salts your muscles and nerves need to function. If you replace the water but not the salts, you can still become unwell. If you replace neither, you will.
The progression is predictable and it is worth knowing because the early stage is easy to miss and easy to fix.
Heat exhaustion comes first. Headache, dizziness, heavy sweating, nausea, muscle cramps, feeling weak or unusually irritable. The skin may be cool and clammy. You are still sweating, which is why people assume they are fine. You feel bad but not alarmed.
Heat stroke is the emergency. The body's cooling system stops working. Sweating may stop altogether. Skin becomes hot and dry. Confusion, slurred speech, loss of coordination, and eventually unconsciousness. This is a medical emergency and it needs an ambulance, not a rest in the shade.
The line between the two is not always obvious, and it can be crossed quickly.
What to arrange before you travel
Three things make a difference and all three are easier to settle before you leave.
Know what your employer provides. Water on site, shade, scheduled breaks in the hottest part of the day, and protective equipment are things an employer should be able to describe before you arrive. If nobody can tell you how the site handles a hot day, that is worth knowing now rather than in July.
Understand your health cover. Heat illness is a medical event and you want to know how it is covered before it happens, not after. Our guide to travel and health insurance for overseas workers (https://www.greenoutdoors.in/blog/travel-and-health-insurance-for-overseas-workers-what-you-actually-need) sets out what to check, and our guide to your pre-departure medical examination (https://www.greenoutdoors.in/blog/preparing-for-your-pre-departure-medical-examination-a-worker-s-guide) explains what the medical check does and does not cover. If you have a heart condition, are taking medication that affects sweating or fluid balance, or have had heat problems before, tell the doctor at your medical and tell your employer. This is not a reason to be refused work. It is a reason for the work to be planned properly.
Plan your working clothes. Light, loose, breathable fabric in a light colour, and a hat with a brim. Cotton is better than synthetic against the skin in dry heat. If your employer issues a uniform, ask whether there is a summer version.
On the day
Start hydrated, not just keep hydrated. Arriving at work already short of fluid is the most common mistake. Drink through the evening before, not only during the shift.
Drink before you feel thirsty. Thirst arrives after you are already behind. Small amounts often is better than a large amount at once.
Replace salts, not only water. If you are sweating heavily for hours, plain water alone can dilute what is left in your body. Oral rehydration sachets are cheap, easy to carry, and worth taking with you. Food with salt in it helps. If your employer provides rehydration salts, use them.
Use the shade in the middle of the day. In many hot regions the working day is deliberately split to avoid the peak hours. If your site does this, the schedule is not a convenience, it is the safety measure. Do not use the break to do heavy personal tasks in the sun.
Watch your urine. Pale yellow and frequent is what you want. Dark and infrequent means you are behind. This is the simplest self-check there is and it costs nothing.
Do not rely on energy drinks. High caffeine and high sugar drinks are not rehydration and can make things worse.
Acclimatisation is real, and it takes time
A worker who has been in a hot climate for two weeks tolerates heat considerably better than the same worker on day two. This is a physical adaptation and it cannot be rushed by willpower. The first week is the riskiest week. Take it more slowly than you think you need to, and do not judge what is sustainable from how you feel on the first day.
If a colleague goes down
Act first and argue later.
Move them out of the sun into shade or, better, into a cool indoor space. Loosen or remove excess clothing. Cool them actively with wet cloths, especially at the neck, armpits and groin, where the big blood vessels are close to the skin. Fan them. If they are conscious and able to swallow, give them fluids with salts, slowly.
Call for medical help. If they are confused, if their skin is hot and dry, or if they become unconscious, this is heat stroke and it is an emergency. Do not wait to see if they improve. Do not leave them alone. Do not give an unconscious person anything to drink.
Things that are not your job to guess
Rules about maximum working temperatures, mandatory breaks and what an employer must provide in hot conditions are set by national law and they differ between countries. We are not going to quote a figure for any of them, because a number quoted from the wrong country, or from an old version of a rule, is worse than no number at all.
Instead, ask two questions when you have them: what are the rules where I am working, and who do I ask if I think they are not being followed. A legitimate employer can answer both. If nobody can, treat that as information about the employer.
What you can do before you go
Read your contract and your health cover documents rather than filing them. Know what is provided and what is not. Take rehydration sachets with you. Pack light, breathable clothing. And treat the first week, wherever you are working, as a period of adjustment rather than a test of stamina.
Heat is manageable. It is the heat that is ignored that sends people to hospital.
