| It is well known that exposure to heat waves and cold spells can cause serious health problems for older people. And fog and air pollution affect the vulnerable of all ages. | It is well known that exposure to heat waves and cold spells can cause serious health problems for older people.

| More than 100,000 people with heart conditions were monitored over a two-year period, during all weathers. For these people the risk of death or needing hospital treatment for heart failure increased with every 1C drop in temperature, especially in winter. | More than 100,000 people with heart conditions were monitored over a two-year period, during all weathers.

| If the temperature dropped 10C in a week, a frequent occurrence in northern climes, there was a 7% rise in admissions of these patients. | If the temperature dropped 10C in a week, a frequent occurrence in northern climes, there was a 7% rise in admissions of these patients. |
| But when the pressure was high for a period of seven days the risk of heart failure increased by 4.5% for every extra 10 millibars in atmospheric pressure. This does not mean the high pressure alone was to blame, rather the weather conditions the pressure caused. | But when the pressure was high for a period of seven days the risk of heart failure increased by 4.5% for every extra 10 millibars in atmospheric pressure.

| The longer the high pressure lasted the greater the risk. In high summer, still, dry, weather creates conditions for a heat wave that will be dangerous for some people, especially if combined with air pollution. | The longer the high pressure lasted the greater the risk.

| But it is the winter systems, often known as blocking highs, that are most deadly. These allow fog to form that over time becomes laden with pollutants. In addition, these are often periods when the temperatures drop steeply, a dangerous combination. | But it is the winter systems, often known as blocking highs, that are most deadly.
