Heatwave: Tips to Stay safe as temperatures rise above 40°C

As Nigeria grapples with an intense early-year heatwave, the Nigerian Meteorological Agency has issued a warning about extreme heat stress affecting millions of citizens across the country.

With temperatures soaring above 40°C in several states and humidity levels worsening the discomfort, health experts are urging Nigerians to take immediate precautions to prevent heat-related illnesses.

In an advisory released on Tuesday, March 10, NiMet described the rising temperatures as a significant health risk. States expected to experience the most severe conditions include Kebbi State, Niger State, Kwara State, Oyo State, Kogi State, Nasarawa State, Anambra State, Abia State, Ebonyi State, Cross River State and the Federal Capital Territory.

Northern states such as Taraba State, Adamawa State, Plateau State, Kaduna State, Zamfara State and Sokoto State are also on high alert.

According to the agency, prolonged exposure to the current weather conditions could lead to thermal discomfort, dehydration, fatigue, headaches and reduced productivity. Vulnerable groups such as pregnant women, children, the elderly, and Muslims observing the Ramadan fast are considered particularly at risk.

Residents across affected areas have already reported adjusting their daily routines, with many choosing to remain indoors during peak sunshine hours. The combination of extreme heat and humidity increases the heat index, making the temperature feel hotter than it actually is and putting additional strain on the body’s cooling system.

*Tips to Stay Safe During the Heatwave*

*Stay hydrated* : Drink at least 2–3 litres of water daily, even before feeling thirsty, to replace fluids lost through sweating.

Eat water-rich foods: Fruits such as watermelon, oranges, cucumbers and pineapple can help maintain hydration. Avoid excessive alcohol and caffeine, which can worsen dehydration.

Avoid peak sun hours: Limit outdoor activities between 11:00 a.m. and 4:00 p.m., when sunlight and heat are most intense.

Dress appropriately: Wear light-coloured, loose-fitting cotton clothing that allows the body to breathe and reflects sunlight.

Protect yourself outdoors: Use sunscreen and carry umbrellas, hats or sunglasses when stepping outside.

Keep indoor spaces cool: Use fans or air conditioners where available. Keep windows and curtains closed during the day to block heat and open them at night for ventilation.

Reduce physical exertion: Postpone strenuous activities such as intense exercise or long walks. Outdoor workers should take frequent breaks in shaded areas.

Cool the body regularly: Take cool showers or baths, and place damp cloths on areas such as the neck or wrists to lower body temperature.

Look out for others: Never leave children, elderly persons or pets in parked vehicles or poorly ventilated spaces. Check regularly on neighbours or relatives with underlying health conditions.

Use oral rehydration when necessary: For excessive sweating, especially among children, oral rehydration solutions may help restore electrolyte balance.

*Symptoms of Heat-Related Illness*

Heat Exhaustion: Heavy sweating, pale or clammy skin, dizziness, nausea, weakness and a rapid pulse.

Heat Stroke (Medical Emergency): Extremely high body temperature above 40°C, confusion or disorientation, hot and dry skin, difficulty breathing, seizures or loss of consciousness.

*When to Seek Medical Help*

Immediate medical attention is advised if someone experiences confusion, fainting, seizures, persistent vomiting, chest pain, breathing difficulties, or stops sweating despite feeling extremely hot.

Authorities say early hydration, seeking shade, and reducing exposure to the sun remain the most effective ways to stay safe as Nigeria continues to experience unusually high temperatures.(Punch)
