A room temperature of 30 degrees Celsius (86 degrees Fahrenheit) is generally considered quite warm for indoor living conditions. While personal comfort can vary, most people find this temperature to be on the higher side. It may feel hot and uncomfortable, especially if you're engaging in physical activity or don't have adequate ventilation or cooling measures.
Furthermore, prolonged exposure to high temperatures can have negative effects on health. It can lead to dehydration, heat exhaustion, and even heatstroke, particularly in individuals who are vulnerable, such as the elderly, young children, or those with certain medical conditions.
To maintain a comfortable and safe indoor environment, it is generally recommended to keep room temperatures between 20 to 24 degrees Celsius (68 to 75 degrees Fahrenheit). However, personal preferences can differ, and some individuals may prefer slightly warmer or cooler temperatures. It's essential to find a balance that suits your comfort while also considering the potential health implications of extreme temperatures.
