Hot Weather in Nigeria: 10 Practical Ways to Protect Your Health During a Heatwave
The heat can make an ordinary day feel much more exhausting. Whether you're commuting to work, sitting in traffic, working outdoors, running errands or trying to get a good night's sleep, unusually hot weather can take a toll on your body.
And it is not just about feeling uncomfortable.
When temperatures rise, your body has to work harder to maintain its normal temperature. If it cannot cool itself effectively, you may become dehydrated or develop a heat-related illness.
This is particularly important for people who spend long hours outdoors, work in poorly ventilated spaces or have limited access to cooling.
The good news is that there are practical steps you can take to protect yourself and the people around you.
Here are 10 ways to manage your health during periods of intense heat.
1. Drink water regularly, even when you are not thirsty
One of the most important things you can do during hot weather is stay hydrated.
Your body loses water through sweating, and this loss can increase when you spend time in hot environments or engage in physical activity.
Do not wait until you feel extremely thirsty before drinking water. Keep a bottle nearby and drink regularly throughout the day.
A few practical habits:
Carry drinking water when leaving home.
Drink water regularly during work, travel and outdoor activities.
Drink water with meals and after physical activity.
Choose water more often than sugary drinks.
Eat water-rich foods such as watermelon, oranges, cucumber and other fruits and vegetables.
The amount of fluid you need depends on your activity, environment and health. People who have been advised to restrict fluids because of a medical condition should follow their healthcare professional's advice.
2. Reduce your exposure to the midday sun
If you can, plan outdoor activities for the cooler parts of the day.
Try to avoid strenuous activities during the hottest hours, particularly around midday and early afternoon. If your work requires you to be outside, take regular breaks and find shade whenever possible.
For example:
Schedule exercise or outdoor errands earlier in the morning or later in the evening.
Take breaks from direct sunlight.
Use an umbrella, hat or other suitable sun protection.
Avoid unnecessary outdoor physical activity during peak heat.
Remember that the temperature reported by weather services is usually measured in the shade. Direct sunlight can make conditions feel considerably hotter.
3. Keep your home and workspace as cool as possible
You do not have to be outdoors to experience the effects of excessive heat. Poor ventilation and indoor heat build-up can also make it difficult for your body to cool down.
Where possible:
Open windows when the air outside is cooler.
Close curtains or blinds to reduce direct sunlight entering rooms.
Use air conditioning where available.
Use fans where they provide effective cooling.
Reduce the use of appliances that generate unnecessary heat.
Move to a cooler room or shaded area when your space becomes uncomfortable.
If you do not have air conditioning, consider spending some time in a cooler, well-ventilated public or indoor space when the heat becomes difficult to manage.
4. Wear light, breathable clothing
What you wear can affect how easily your body releases heat.
Choose loose-fitting, lightweight clothing that allows air to circulate. Light-coloured clothing can also help reduce heat absorption from sunlight.
When going outside, consider:
Lightweight cotton or other breathable fabrics.
Loose-fitting clothes.
A hat or cap to protect your head.
Sunglasses to protect your eyes.
Suitable sunscreen on exposed skin.
Avoid wearing heavy clothing for long periods in hot environments where possible.
5. Pay attention to how your body feels
Heat-related illness can develop when your body struggles to regulate its temperature.
Early signs that you may be overheating include:
Heavy sweating.
Headache.
Dizziness or light-headedness.
Unusual weakness or tiredness.
Muscle cramps.
Nausea.
Feeling faint.
If you notice these symptoms, stop what you are doing. Move to a cooler place, rest and drink water if you are fully conscious and able to swallow.
Do not try to push through the discomfort or continue strenuous activity.
If symptoms are severe, persist or worsen, seek medical attention.
6. Take extra care of children and older adults
Some people are more vulnerable to the effects of extreme heat.
This includes infants, young children, older adults, outdoor workers and people living with certain medical conditions, including heart, lung and kidney conditions.
Children may not always recognise or communicate when they are becoming overheated. Older adults may also be more vulnerable, particularly if they live alone or have an underlying health condition.
During very hot weather:
Make sure children have access to drinking water.
Dress them in light, comfortable clothing.
Limit prolonged outdoor play during peak heat.
Check on older relatives and neighbours.
Help vulnerable family members access cooler spaces.
Never leave a child, older adult or pet unattended in a parked vehicle.
A parked vehicle can become dangerously hot very quickly, even when the windows are slightly open.
7. Be mindful of exercise and physical work
Exercise is important for your health, but intense physical activity in hot conditions can increase the risk of heat-related illness.
If you normally walk, jog, play sports or exercise outdoors, consider adjusting your routine.
You can:
Exercise during cooler hours.
Reduce the intensity or duration of your workout.
Take regular rest breaks.
Drink water before, during and after activity.
Stop if you experience dizziness, nausea, cramps or unusual weakness.
People whose jobs involve outdoor labour, driving, construction, market activities or prolonged exposure to heat should also take regular cooling breaks.
8. Know when heat becomes a medical emergency
It is important to recognise the difference between feeling uncomfortable in hot weather and experiencing a serious heat-related illness.
Heat exhaustion can cause heavy sweating, weakness, dizziness, headache, nausea and muscle cramps.
Heatstroke is a medical emergency. Warning signs can include confusion, unusual behaviour, seizures, collapse or loss of consciousness. The person may have a very high body temperature, and their skin may be hot. Do not assume that someone is safe because they are still sweating.
If you suspect heatstroke:
Seek emergency medical help immediately.
Move the person to a cooler or shaded area.
Begin cooling them promptly with cool water, wet cloths or towels, and cold packs where available.
Remove unnecessary outer clothing.
Stay with the person and monitor them while waiting for help.
Do not give fluids to someone who is confused, unconscious or unable to swallow safely. Do not delay medical attention while trying home remedies.
9. Do not ignore your usual health needs
Hot weather can place additional strain on the body, particularly for people living with existing health conditions.
If you have a medical condition or take regular medication, speak with your healthcare professional about any precautions you should take during periods of extreme heat.
Do not stop or change prescribed medication on your own.
Pay attention to unusual symptoms and keep important health information accessible, including your allergies, medical history, medications and recent test results.
If you feel unwell, seek appropriate medical advice rather than assuming the heat is the only cause.
