These announcements should communicate the anticipated arrival, duration, and severity of the potential heat wave. Calculating heat removed by cooling system using output fluid temperature. Evaporation occurs more quickly, and the cooling effect is more noticeable with high wind speeds and low relative humidity. Instruments in space like the Atmospheric Infrared Sounder (AIRS) on NASAs Aqua satellite and the ECOsystem Spaceborne Thermal Radiometer Experiment (ECOSTRESS) on the International Space Station (ISS) provide useful data for studying heat stress. Climate Adaptation Extreme Heat and Health, Centers for Disease Control and Prevention: Extreme Heat, The Centers for Disease Control's summary of Heat Response Plans, Potential risk factors (e.g., being very young or old, using certain medications, having physical or mental impairments that restrict mobility, homelessness or lack of access to air conditioned spaces, being socially isolated, working or spending extended time outside), Symptoms of excessive heat exposure (e.g., dizziness, nausea, confusion, muscle cramps), Recommended response and treatment (e.g., seek air-conditioned locations, stay hydrated), Provide community cooling centers, particularly in areas with low-income, elderly, and young populations, Ensure proper functioning of energy and water systems, Encourage citizens to check on their family, friends, and neighbors to ensure they have access to air conditioning, Communicate heat warning information and appropriate responses to the public (e.g., encourage staying indoors, provide symptom reminders), Establish systems such as hotlines to alert public health officials about high-risk or distressed individuals, Encourage energy conservation to reduce demand on electricity systems, Implement load restrictions for older roads, bridges, and rail to reduce traffic on vulnerable transportation infrastructure.
