April 09, Colombo (LNW): Authorities have cautioned that elevated temperatures are likely to affect large parts of the country on 10 April, with residents in multiple provinces advised to take precautions against the heat.
The advisory highlights that the “heat index” — which reflects how hot conditions feel to the human body when humidity is factored in — may reach cautionary levels in areas including the Western, Sabaragamuwa, Southern, Eastern, North-Western, Northern and North-Central provinces, as well as Monaragala District.
Meteorological officials explain that this index combines air temperature with relative humidity to provide a more accurate sense of discomfort and potential health risks. Even if actual temperatures are not extreme, high humidity can intensify the sensation of heat significantly.
Health experts warn that extended periods outdoors, particularly under direct sunlight, could result in tiredness and dehydration. In more severe cases, continued exposure without adequate rest or hydration may lead to muscle cramps and other heat-related conditions.
Members of the public are being urged to drink plenty of fluids, seek shade where possible, and avoid physically demanding activities during the hottest parts of the day. Special attention is also advised for vulnerable groups such as children, older adults, and those with existing health conditions, as they may be more susceptible to the effects of heat.
