July 2007: Heatwave
During summer young children under 4 years of age, and older people - especially those who live alone or in care homes, are at particular risk from the effects of the heat. Others at risk are those suffering from mental health problems, those with dementia, people suffering from chronic ill health e.g. breathing or heart problems, people who are physically active such as manual workers.
In August 2003 about 27,000 people across Europe, including 2,000 in England died as a result of the heatwave, 80% of these people were aged 75 and over. This is due to dehydration and heat exhaustion, which can cause irreversible damage to various internal organs leading to death.
In a severe heatwave the body can overheat, and dehydrate with the following symptoms:
- headaches
- nausea
- an intense thirst
- sleepiness
- cramps in arms or legs
- hot red and dry skin
- a sudden rise in temperature
- confusion and aggression
- convulsions and a loss of consciousness
To avoid dehydration and heat stroke:
- Plan your day so you stay out of the heat
- Avoid going out 11am-4pm - the hottest part of the day
- If you go out, stay in shade, wear a hat and light, loose cotton clothes
- Carry water
- At home take cool showers or baths - splash yourself with cold water, particularly face and back of your neck
- Eat as normal. Eat more cold food - salads and fruit. Avoid alcohol and caffeine which can increase dehydration.
- Check on older relatives to ensure they are staying cool, and drinking plenty of fluids.
