Heat-Health Watch regions:
|
|
What do the different levels mean?
Level 1 - Awareness — the minimum state of vigilance during the summer. The majority of the time the risk of a heatwave will be less than 50%. However, when the risk exceeds 50% this will be indicated by 'Level 1 - Awareness - Increased risk'.
|
Advice for level 1:
If you are worried about what to do, either for yourself or somebody you know who you think might be at risk, contact NHS Direct at www.nhsdirect.nhs.uk or on 0845 4647.
|
Level 2 - Alert — triggered as soon as the risk is 80% or above for threshold temperatures being reached in one or more regions on at least two consecutive days and the intervening night.
|
Advice for level 2:
Heatwaves can be dangerous, especially for the very young, very old or those with chronic diseases.
|
| Advice on how to reduce the risk, either for yourself or somebody you know, can be obtained from NHS Direct at www.nhsdirect.nhs.uk or on 0845 4647, or from your local pharmacist. |
Level 3 - Heatwave — triggered as soon as the Met Office confirms threshold temperatures will be reached in one or more regions.
Level 4 - Emergency — reached when a heatwave is so severe and/or prolonged that its effects extend outside the health and social care system.
Advice for level 3 or 4:
Stay out of the sun. Keep your home as cool as possible — shutting windows during the day may help. Open them when it is cooler at night. Keep drinking fluids. If there is anyone you know who might be at special risk, for example an older person living on their own, make sure they know what to do. |
