Social effects of a heat wave

• A clear outcome of heat waves is a rapid rise in mortality. When a heat wave strikes communities can sometimes lose a mass of people through environmental and just simply the effects resulting from the extreme heat.
• Excessive heat which comes from heat waves and droughts causes psychological stress, to a degree which affects performance, and is also associated with an increase in violent crime.
• Extreme heat can cause diverse problems with health. Heat waves usually cause mass dehydration which can cause a long list of problems. 
• Heat waves also effect transport, through speed reductions on rail networks and the deterioration of surfaces on roads that have not been resealed following new standards for asphalting.
