Nigeria could experience an additional 31,400 heat‑related fatalities from September 2026 to February 2027, according to a projection by the Climate Impact Lab. The estimate links the surge in deaths to a strengthening El Niño pattern, prompting urgent calls for Nigerians to adopt practical measures that mitigate heat stress.
Key points from the report include:
- An expected rise of 31,400 heat‑related deaths within a six‑month window.
- Heat exposure can trigger dehydration, heat exhaustion, heatstroke, headaches, dizziness, fainting, skin rashes, sunburn, disrupted sleep and reduced concentration.
- Vulnerable groups such as the elderly, children and people with chronic illnesses face heightened risk.
- Immediate lifestyle changes—hydration, appropriate clothing, altered work schedules and improved shade—are recommended to curb the health impact.
When does heat become dangerous?
Severe weakness, dizziness, persistent headaches, nausea or profuse sweating may signal heat exhaustion. Move the individual to a cooler environment, loosen tight clothing and help them cool down. If they are fully conscious and can swallow safely, provide water.
What should be done in a heatstroke emergency?
Heatstroke is a medical emergency. Call emergency services without delay and begin cooling the person while awaiting help. Do not give fluids to anyone who is confused or unconscious. Prioritise older adults, young children and persons with conditions like diabetes.
How can you stay hydrated?
Keep a supply of safe drinking water at your desk, in transit or while shopping. Sip regularly instead of waiting for thirst to appear. Water‑rich foods—such as watermelon, oranges and cucumber—can supplement hydration but should not replace plain water. Those on medically prescribed fluid limits must follow their clinician’s guidance.
What clothing choices help in hot weather?
Opt for loose, lightweight fabrics like cotton or linen. Light‑coloured garments and breathable shoes improve comfort. A wide‑brimmed hat, sunglasses and an umbrella add extra protection outdoors. If formal attire is required, select lighter fabrics and consider layering with breathable pieces.
How can daily routines be adjusted?
Ask whether errands truly need to be done at noon. Shift walks, exercise or market trips to early mornings or evenings when temperatures are lower. Schedule strenuous outdoor work for cooler periods and minimise direct sun exposure during peak heat hours. Outdoor workers should take frequent shaded breaks, and parents must monitor children’s play, sports and school activities. Never leave a child unattended in a parked vehicle.
What home improvements reduce indoor heat?
Air‑conditioning may be unaffordable for many, but closing curtains or blinds during the hottest part of the day blocks solar gain. When outdoor air is cooler, open windows safely to enhance ventilation and use fans to circulate air. Avoid indoor activities that generate excess heat during peak temperatures.
Why is sunscreen important?
Apply a broad‑spectrum, water‑resistant sunscreen with at least SPF 30 to exposed skin before heading outside. Reapply every two hours, or sooner after swimming or heavy sweating, following product directions. Sunscreen complements—not replaces—shade, protective clothing and limited sun exposure.
What responsibilities do institutions have?
- Schools should rethink outdoor sports, assemblies and other strenuous activities during the hottest periods, while ensuring students have ready access to drinking water and cool spaces.
- Employers, especially those with outdoor staff, need to adjust work schedules where feasible, provide adequate rest breaks and heed heat warnings seriously.
- Government must enhance public safety by installing shade structures at bus stops, motor parks and other high‑traffic areas where commuters spend long periods exposed to the sun. Prioritising covered waiting areas is essential for community health.
By integrating these habits and policies, Nigerians can better protect themselves against the mounting threat of extreme heat.
