The Lagos State Government has warned residents to prepare for possible extreme heat as the strengthening El Niño climate pattern and the transition into the dry season raise concerns about rising temperatures, dry spells, dust and deteriorating air quality across Nigeria.
The Commissioner for the Environment and Water Resources, Tokunbo Wahab, issued the advisory on Friday, urging residents to take preventive measures to protect their health and prepare for potential environmental challenges.
Wahab explained that Lagos, as a densely populated coastal city, could experience intensified heat due to buildings, roads, limited green spaces and poor ventilation in some neighbourhoods, particularly densely populated communities and informal settlements.
He warned that prolonged exposure to excessive heat could cause dehydration, heat exhaustion and heatstroke. Children, older persons, pregnant women, outdoor workers, street traders, construction workers, waste handlers and people with underlying health conditions were identified as particularly vulnerable.
The commissioner also cautioned that heat conditions could worsen existing air pollution, as dry-season dust and haze may aggravate respiratory problems. Increased use of petrol- and diesel-powered generators during power outages could further deteriorate air quality. Residents were therefore advised to avoid open burning of refuse and limit exposure to dusty environments, especially those with respiratory conditions.
To minimise the risks, residents were urged to drink water regularly, wear lightweight and breathable clothing, seek shade and well-ventilated spaces, and avoid strenuous outdoor activities during the hottest hours. Schools, markets, workplaces and public facilities were also encouraged to provide drinking water, adequate ventilation and shaded areas.
Wahab advised residents to watch for symptoms of heat-related illnesses, including excessive sweating, dizziness, headaches, weakness, nausea and muscle cramps. Anyone experiencing these symptoms should be moved to a cooler environment and given appropriate cooling assistance, with medical attention sought where necessary. Sudden collapse or loss of consciousness, he stressed, should be treated as a medical emergency.
He further called for collective action to reduce urban heat through tree planting, protection of existing trees, preservation of green spaces, proper waste disposal and environmentally responsible practices.
The commissioner emphasised the need for collaboration among government agencies, health institutions, environmental experts, businesses and community stakeholders to strengthen climate preparedness and resilience.
He assured residents that the ministry, through its relevant agencies, would continue public awareness efforts and work with the Nigerian Meteorological Agency (NiMet), the Lagos State Ministry of Health and the Lagos State Emergency Management Agency (LASEMA) to improve preparedness and response to emerging environmental risks.
