by The National Weather Service (NWS) has issued Heat Advisories and Extreme Heat Warnings for parts of Arizona, Nevada, Idaho, Washington, Oregon, California, Texas, and Oklahoma as a dangerous heat wave is set to persist through the weekend and into next week.
Authorities are urging residents in these eight states to avoid direct sunlight, particularly during peak afternoon hours, to reduce the risk of heat-related illnesses.
Risks of Extreme Heat
Exposure to extreme heat can lead to serious conditions such as heat exhaustion and heatstroke, which can be life-threatening if not treated promptly. Vulnerable groups, including older adults, children, and individuals with preexisting health conditions, face the greatest risk.
The Centers for Disease Control and Prevention (CDC) warns that direct sun exposure increases body temperature and can intensify the effects of heat. Staying in shaded or air-conditioned areas during the hottest parts of the day significantly lowers the risk of heat-related illness.
Similarly, the NWS advises avoiding prolonged exposure to the sun during heat advisories to prevent heat stress and safeguard public health.
