It's Too Hot: How To Stay Safe During The Caribbean Heat

Lately, it feels as though everyone in the Caribbean is saying the same thing.
"This heat is unbearable."
We joke about melting and that “whatever God is cooking… it done.” We complain about how impossible it is to sleep. We laugh about needing three showers a day and still feeling sticky five minutes later. But beneath the humour is a reality we should not ignore:
Extreme heat is more than uncomfortable. It can become dangerous.
For many of us, the heat isn't lasting for a weekend or a single heatwave. It stretches on for weeks and sometimes months, affecting our sleep, our energy, our mood, our productivity and, for some people, their health.
This isn't the heat we grew up with.
Climate scientists have been saying for years that the Caribbean is among the regions most vulnerable to the effects of climate change — and what we are experiencing now, the sustained, relentless heat that stretches week after week, is part of that reality.
As temperatures continue to rise, understanding Caribbean heat safety is no longer simply about staying comfortable. It helps us respond not just as individuals managing discomfort, but as communities facing a long-term challenge that requires long-term thinking.
The good news is that there are simple things we can do to reduce the immediate risks to ourselves and our loved ones and stay safe in times of extreme heat.
Don't Wait Until You Feel Sick
One of the biggest mistakes people make is waiting until they feel dizzy or unwell before taking the heat seriously. By the time you develop symptoms such as dizziness, nausea or weakness, your body may already be struggling to regulate its temperature.
Instead, think about staying cool as something you do throughout the day, not just when you begin feeling overheated.
Drink fluids regularly rather than waiting until you feel thirsty. If your urine is consistently dark yellow, it may be a sign that you need to drink more fluids.
Wear lightweight, loose-fitting clothing whenever possible. Choose lighter colours that reflect rather than absorb heat. If you need to be outdoors, wear a wide-brimmed hat or use an umbrella to reduce direct sun exposure. A good pair of sunglasses can also help protect your eyes from the intense sunlight while making it more comfortable to spend time outdoors.
Whenever possible, schedule errands, exercise or outdoor work early in the morning or later in the afternoon when temperatures are lower. If you work outside, take regular breaks in the shade. Rest is not laziness. It is one of the ways your body protects itself.
If you're spending long periods outdoors, don't forget sunscreen on exposed skin. Protecting yourself from the heat and protecting yourself from the sun go hand in hand.
If you take regular medication and find yourself struggling unusually with the heat, speak with your doctor or pharmacist. Some prescription medicines, over-the-counter medicines and even certain herbal remedies can affect the body's ability to regulate temperature or increase the risk of dehydration.
Protecting yourself during periods of extreme heat isn't about avoiding the outdoors altogether. It is about understanding your body's limits and making small adjustments before the heat becomes dangerous.
Keeping Your Home Cooler
Not everyone has air conditioning. I myself do not. Many Caribbean families rely on fans, open windows and whatever breeze they can find. While these may not eliminate the heat, small changes can make your home more comfortable.
Close curtains or blinds during the hottest part of the day to reduce direct sunlight entering the house. Open windows in the early morning or evening, when temperatures are lower, to encourage airflow if it is safe to do so. One thing that has made a noticeable difference in my own home is using blackout curtains. Rather than keeping every curtain open all day, I keep the blackout curtains closed in the rooms where the afternoon sun is hitting the walls or shining directly through the windows. On the cooler side of the house, I open the curtains to let in natural light. As the sun moves, I switch them. It helps reduce the amount of heat building up inside the house and can make the rooms feel noticeably cooler.
Use fans to improve air circulation, remembering that fans help cool people more than they cool rooms. I also have more than one in the rooms I use more. If you're using a fan, try creating cross ventilation by opening windows on opposite sides of the house whenever it is cooler outside. Moving air through the home is often more effective than simply circulating the same hot air. Turn off unnecessary lights and electrical appliances that generate additional heat.
Choose lightweight bedding and clothing to sleep in. Consider taking a cool shower before bed to help lower your body temperature and improve sleep.
If you live beneath a zinc roof, you already know that the temperature inside your home can become much hotter than outside. Spending time in the coolest room of the house during the afternoon can sometimes make a noticeable difference.
Eat For The Weather
During very hot weather, many people naturally lose their appetite. That's okay. Instead of eating one or two large, heavy meals, consider smaller, lighter meals throughout the day.
Fresh fruits with high water content, salads and other lighter foods can feel easier on the body during periods of intense heat. Freeze a bottle of water overnight before long journeys or outdoor activities. As it melts throughout the day, you'll have cool drinking water for much longer. Alcohol can contribute to dehydration, while excessive caffeine may do the same for some people.
Water is essential, but if you are spending long hours outdoors, exercising, teaching classes, working in the sun or sweating heavily for extended periods, you may also benefit from replacing electrolytes lost through sweat. Sports drinks, oral rehydration solutions or electrolyte tablets can help in these situations. Personally, I keep cold coconut water in the fridge during particularly hot weeks. When I've been teaching outdoors or spending long periods in the heat, I find it a refreshing way to rehydrate alongside drinking plenty of water. I also keep a jug of homemade iced tea in the fridge. I find I'm much more likely to keep drinking fluids throughout the day if they're cold and refreshing rather than forcing myself to drink plain room-temperature water. Remember, the goal is not simply replacing water, but also replacing some of the salts your body loses during prolonged sweating.
Paying attention to how your body responds becomes even more important during prolonged periods of hot weather.
Exercise Smarter, Not Harder
Staying active is important, but extreme heat may require some adjustments.
Exercise earlier in the morning or later in the evening whenever possible. Reduce the intensity of your workout if temperatures are unusually high. Drink water before, during and after exercise. If you're struggling to sleep, avoid doing strenuous housework or exercise immediately before bed, as your body temperature needs time to fall before you can sleep comfortably.
Most importantly, listen to your body.
If you begin feeling faint, dizzy, nauseated or unusually exhausted, stop exercising immediately, move into the shade or a cooler area and begin cooling down.
Pushing through extreme heat is not a sign of strength. Recognising your limits is.
A Few Other Things That Help Me
Over the years, I've picked up a few habits that make the heat a little more manageable. They may not all work for everyone, but they've certainly helped me.
If you have long, thick hair like me and have a tendency to sweat in it, think about how you're wearing it during prolonged periods of extreme heat. Many Caribbean women and men naturally have thick, curly or coily hair that can trap heat around the head and neck. Wearing your hair in plaits, cornrows, braids or another protective style may allow for better airflow and make you feel more comfortable, especially if you spend time outdoors.
When I feel really heated, I run cool water over my wrists, face and arms. It sounds weird, but I also rinse out my mouth. Not sure why it helps, but it works! Also, sometimes, I put a cool cloth around my neck. It’s a little thing, but it can help your body cool more quickly during very hot weather.
One thing I always do is unlock the car, open all the windows and let the trapped hot air escape before I get in. Even a minute or two can make a surprising difference. I also use a windscreen visor and put a small towel on my steering wheel, whenever I'm parked. It doesn't stop the car from getting hot, but it helps reduce the amount of direct sunlight heating the dashboard and steering wheel. And here's a little tip many people don't realise: the trunk is usually the coolest part of the car. I keep things like my yoga mat there instead of on the back seat, where they would spend hours baking in direct sunlight.
Check On The People Most At Risk
Heat does not affect everyone equally.
Older adults often become dehydrated more easily and may not notice the warning signs as quickly. Young children cannot regulate body temperature as effectively as adults.
Pregnant women, people living with heart disease, diabetes or other chronic illnesses, and those taking certain medications may also be at greater risk.
People who work outdoors including, construction workers, farmers, gardeners, delivery drivers, security officers, traffic wardens and vendors are exposed to heat for much longer periods than most of us.
Take a few minutes to check on family members, neighbours or friends who may be vulnerable. Sometimes a simple phone call can make all the difference.
Heat Doesn't Affect Everyone Equally
Advice like "stay inside" or "turn on the air conditioning" sounds simple, but it isn't realistic for everyone.
Many Caribbean families live beneath zinc roofs that trap heat throughout the day. Some people work outdoors because staying home means losing income. Others experience power outages just when they need fans or air conditioning most. Some communities have limited access to cool public spaces.
Extreme heat is not only a weather issue. It is also a public health issue and, for many families, an economic one. Recognising these realities helps us respond with compassion instead of judgement.
Don't Ignore The Warning Signs
Heat-related illnesses usually develop gradually, but they can become life-threatening if ignored.
Heat Exhaustion — is the body's warning that it is struggling to cope. Common symptoms include:
Heavy sweating
Weakness or fatigue
Dizziness or light-headedness
Headache
Muscle cramps
Nausea or vomiting
Cool, pale or clammy skin
If someone develops these symptoms:
Move them into the shade or a cool place.
Encourage them to sip cool water if they are fully alert.
Loosen or remove unnecessary clothing.
Cool the body using damp cloths, cool showers or fans.
If symptoms worsen or do not improve, seek medical attention.
Heatstroke — Heatstroke is a medical emergency. Warning signs may include:
Confusion or unusual behaviour
Difficulty speaking
Loss of consciousness
A very high body temperature
Hot skin (which may be dry or still sweating)
If you suspect heatstroke: Call emergency medical services immediately.
Move the person into the shade.
Begin cooling them immediately using cool water, wet towels, fans or ice packs placed on the neck, armpits and groin while waiting for medical help.
Do not delay treatment while hoping they will recover on their own.
Don't Forget Your Mental Wellbeing
Living with relentless heat is exhausting. Poor sleep, constant discomfort, difficulty concentrating, feeling irritable or unusually emotional are all experiences that many people report during prolonged periods of extreme heat.
Be patient with yourself. Recognise that your body is working harder simply to stay cool. Whenever possible, build small moments of recovery into your day, even if that simply means sitting quietly with a cool drink in the shade for a few minutes.
Looking After One Another
The Caribbean has always known how to care for its communities. We check on neighbours after storms. We share food when someone is struggling. We look out for older relatives and vulnerable friends. Extreme heat asks us to extend that same spirit of care.
Sometimes protecting someone doesn't require special equipment or medical training.
Sometimes it begins with asking a simple question. "Are you okay?"
During periods of extreme heat, that question could save a life.
