A fresh spell of extreme summer weather has prompted US authorities to issue heat advisories across parts of Texas and Oklahoma, with forecasters warning that temperatures combined with humidity could make conditions feel as hot as 110 degrees Fahrenheit.
The National Weather Service has cautioned residents that the combination of intense heat and moisture in the air significantly increases the risk of heat-related illnesses, particularly for vulnerable groups such as the elderly, children and outdoor workers.
The advisory comes as much of the southern United States continues to experience an early-season heat wave, raising concerns about public health and safety.
Heat index expected to reach dangerous levels
According to the Hindustan Times, meteorologists have warned that actual temperatures, coupled with high humidity levels, could push the heat index into the range of 105 to 110 degrees Fahrenheit in several areas.
The heat index measures how hot conditions feel to the human body when humidity is factored in alongside air temperature. Higher humidity reduces the body's ability to cool itself through sweating, increasing the likelihood of heat exhaustion and heat stroke.
Weather officials have urged people to limit outdoor activities during the hottest parts of the day and remain indoors whenever possible.
Authorities have also stressed the importance of checking on elderly neighbours, relatives and anyone who may be particularly vulnerable to extreme heat.

Residents urged to take precautions
According to the Hindustan Times, the National Weather Service has advised people to drink plenty of fluids throughout the day and spend as much time as possible in air-conditioned environments.
Residents have been encouraged to wear loose-fitting, lightweight clothing and avoid direct sunlight for extended periods. Those who must work outdoors are being urged to schedule physically demanding activities during the early morning or late evening hours when temperatures are lower.
Officials have also highlighted the dangers of leaving children or pets unattended inside vehicles. Even on moderately hot days, temperatures inside a parked car can rise rapidly to life-threatening levels within minutes.

Heat-related illnesses remain a serious concern
According to the Hindustan Times, health experts warn that prolonged exposure to extreme heat can lead to heat exhaustion, which may cause dizziness, weakness, nausea and excessive sweating. If left untreated, it can progress to heat stroke, a medical emergency that can result in organ failure and death.
The Occupational Safety and Health Administration has advised employers to provide regular breaks for outdoor workers in shaded or air-conditioned areas. Anyone showing symptoms of heat-related illness should be moved immediately to a cool location and given medical assistance if necessary.
Authorities continue to monitor weather conditions across the region and have urged residents to stay updated through local forecasts and emergency alerts as the heat wave persists.
