A heatwave is affecting Guinea, prompting Dr. Mohamed Fanta Condé, a public health specialist, to alert the public about the risks of "invisible" dehydration. On November 12, 2026, Dr. Condé appeared on the RTG's Grand Angle program to discuss the effects of heat on the body and provide vital recommendations to protect vulnerable populations. He explained that the human body regulates its temperature at 37°C, but excessive heat can disrupt this balance, leading to severe consequences.
Dr. Condé warned that the disruption of the body's thermoregulation mechanism can simultaneously affect the cardiovascular, nervous, respiratory, renal, and muscular systems. This can cause an accelerated heart rate, decreased blood pressure, dizziness, cramps, and even seizures or heart attacks in severe cases. The specialist emphasized that one of the most significant and invisible signs of heat stress is dehydration, which can cause significant damage before becoming apparent.
The specialist advised consuming two to three liters of water per day and recommended drinking a glass of water before bed and upon waking to help regulate blood circulation. However, Dr. Condé cautioned against drinking ice-cold water, as the body needs to expend extra energy to bring it to a normal temperature, putting additional strain on the body and brain. He suggested opting for room temperature or slightly cool water instead.
Dr. Condé identified vulnerable populations, including infants, schoolchildren, pregnant women, and outdoor workers, as being at high risk. He stressed the importance of frequent breastfeeding for infants aged 0-6 months, as breast milk is composed of at least 70% water. In schools, where cases of fainting have been reported in overheated and poorly ventilated classrooms, Dr. Condé urged authorities to take action to prevent further incidents.
The specialist also highlighted the risks faced by people with chronic diseases, such as diabetes, hypertension, and kidney disease, and called for increased vigilance in areas where meningitis is prevalent, such as Haute-Guinée. He advocated for workers in outdoor settings, particularly in gold mining areas, to be given regular breaks in shaded areas to hydrate.
Dr. Condé emphasized the importance of protecting pregnant women, who should limit their movements during the hottest parts of the day and drink plenty of water to ensure the health of their fetus. He warned that inadequate hydration during pregnancy can lead to oxygen deprivation for the baby, potentially resulting in nerve damage and long-term consequences such as cerebral palsy.
The health expert concluded by urging the public to take precautions to prevent heat-related illnesses, particularly among vulnerable populations. By following his recommendations and staying informed, Guineans can reduce their risk of dehydration and other heat-related health issues during this abnormal heatwave.
