What is heat stress and how is it different from feeling hot?

"Heat stress is a medical condition, not just physical discomfort. It occurs when the body's heat regulation system is overwhelmed and core body temperature rises to dangerous levels. Unlike ordinary warmth, heat stress can lead to organ damage and death if untreated. The Heat Index which combines air temperature and humidity determines real risk, not the thermometer reading alone."

Which states in Nigeria are most affected by the 2026 heat warning?

"According to the March 2026 heat warning, the highest-risk zones classified as 'Take Action' cover much of the south-west, parts of north-central Nigeria, and sections of the south-south. Several northern states fall into the 'Be Prepared' zone. The FCT and surrounding states are also in elevated risk categories. All Nigerians should treat this period with caution regardless of zone."

What are the symptoms of heat stress in adults?

"Common symptoms include heavy sweating, dizziness, weakness, nausea, headache, and rapid heartbeat. As the condition progresses, sweating may stop, which is a dangerous sign. Confusion, hot dry skin, and loss of consciousness indicate heat stroke, which requires immediate emergency medical attention."

How do you treat heat stress at home?

"For mild to moderate heat stress: move the person to a cool or shaded area immediately, remove excess clothing, apply cool water or a wet cloth to the skin (especially the neck, armpits, and groin), and give water to drink in small, frequent sips. Do not give fluids to someone who is unconscious. If symptoms do not improve within 15–30 minutes, or if heat stroke symptoms appear, seek emergency medical help immediately."

Is heat stress the same as heat stroke?

"No. Heat stroke is the most severe stage of heat stress, but heat stress covers a range of conditions from mild heat cramps to dangerous heat exhaustion. Heat stroke is specifically when the body temperature rises above 40°C and the brain and organs are at risk. Heat cramps and heat exhaustion can often be managed with rest and rehydration. Heat stroke always requires emergency medical care."

Why is March one of the hottest months in Nigeria?

"March falls in Nigeria's peak transitional heat window after the Harmattan dry season ends but before the rainy season begins. During this window, moderating winds have died down, humidity is rising, and the sun strikes at a near-direct overhead angle across the tropical belt. It is historically the most vulnerable heat period of the year, and climate change is intensifying it further."

How can I protect my children from heat stress in Nigeria?

"Never leave a child in a parked vehicle. Dress infants in light, breathable clothing with good airflow. Increase breastfeeding or feeding frequency during hot days. Keep children indoors between 12 noon and 4pm. Monitor for signs of overheating, irritability, reduced urination, flushed skin and cool them down with damp cloth if necessary. Seek medical attention if symptoms persist."
