The head of the Environmental Protection faction in Parliament has described the ultraviolet radiation levels in Tehran as critical and criticized the responsible authorities for inadequate and untimely information dissemination. Sima Rezaei announced on Friday, August 4, that the UV index in the capital reached 12 and urged Tehran residents to avoid sun exposure from 8 AM to 5 PM. According to the UV index chart, a value of eleven or higher is classified as having 'dangerous' effects on skin and eyes, and individuals exposed to sunlight with such a high index are advised to use protective gear such as hats, UV-blocking sunglasses, and sunscreen. The head of the Environmental Protection faction did not specify the responsible agencies for announcing this information but stated that she would request a report from the 'relevant authorities' about the actions taken next week. One of the opponents of announcing the UV radiation index in past years has been Mehrdad Ghatrā Samāni, head of the Ozone Measurement Center of Iran and the Middle East, who believes that publicizing this index causes 'panic and public anxiety.' According to the head of the Environmental Protection faction, from the beginning of October last year to August 4 this year, the average temperature in Tehran province has increased by one degree compared to the past thirty years. While officials of the Islamic Republic of Iran have announced 'heat' as the reason for nationwide closures on August 11 and 12, many users on social media have attributed this closure to 'electricity shortages.' Following the heatwave, some reports indicate the occurrence of fires and mine explosions caused by the fire around Evin Prison. Iranian news agencies reported on Friday, August 4, that parts of the grasslands around Evin Prison in Tehran caught fire, and several mines exploded in the area.
