Health officials have issued an amber heat health alert for several regions in England. This system is designed to provide early warnings to healthcare providers, social care sectors, voluntary organisations, and government departments when temperatures are likely to impact public health.
What alerts are in place?
The UK Health Security Agency has issued an amber heat health alert for the East Midlands, West Midlands, East of England, London, and the South East. Yellow alerts are in place for the South West, North West, North East, and Yorkshire and the Humber.
What do these alerts mean?
The alert system uses three levels: yellow, amber, and red, depending on the expected impact. Yellow alerts indicate that most people are unlikely to be affected, but vulnerable individuals may struggle. Amber alerts signal that the impact is expected across the entire health service, with the potential for the whole population to be at risk, requiring a coordinated response from services.
When are they in place?
The alerts are active from 2pm on Friday until 5pm next Wednesday.
Which groups are particularly vulnerable?
According to the NHS, the most vulnerable groups include older people, especially women over 75, those living alone or in care homes, individuals with long-term illnesses such as heart or lung conditions, diabetes, Parkinson's, and some mental health conditions, as well as patients on multiple medications. Babies, very young children, people dependent on alcohol or drugs, and those with Alzheimer's disease are also at higher risk.
What are the main risks?
Dehydration from not drinking enough water is a key risk, while overheating can worsen symptoms for those with heart or breathing problems. Heat exhaustion occurs when the body overheats and loses too much water and salt, with signs including tiredness, dizziness, headaches, nausea, excessive sweating, and intense thirst. If not cooled down within 30 minutes, heat exhaustion can lead to heatstroke, a life-threatening condition. The NHS advises moving the person to a cool place, removing unnecessary clothing, giving cool water or a sports drink, and cooling their skin with water or a fan.
How can vulnerable people stay safe?
The NHS recommends staying out of the sun between 11am and 3pm, wearing sunscreen, a hat, and light clothing, avoiding exercise, alcohol, caffeine, and hot drinks, and opting for cold food and drinks. To keep homes cool, close windows during the day and open them at night when temperatures drop. Electric fans can help if the temperature is below 35C.
