Cold weather health alerts are an essential public service aimed at protecting lives, health, and infrastructure when temperatures plunge dangerously low. These alerts, developed by the UK Health Security Agency (UKHSA) alongside the Met Office, provide critical warnings about cold weather risks between November 1st and March 30th each year. But what makes these alerts so vital, and how are they categorized to keep everyone informed and safe?
What Are Cold Weather Health Alerts?
Cold weather health alerts are warnings issued when low temperatures pose a significant threat to public health. Designed to reduce illness and fatalities related to cold weather, such as hypothermia and increased risk of heart or stroke incidents, these alerts also protect essential services like power supplies and transportation networks.
Issued jointly by the UKHSA and the Met Office, the alerts not only keep the general public informed but also provide guidance to NHS England, government departments, and healthcare professionals. For instance, during the winter of 2024-25, amber and yellow alerts were issued across most regions, reflecting elevated weather risks.
These warnings are categorized by their severity, ranging from green (minimal risk) to red (extreme risk). Each level of alert carries specific precautions for the public and professionals.
How Are Alerts Categorized?
Each level of cold health alert is designed to reflect the potential health and service challenges posed by cold weather:
- Green: Minimal risk to health. Routine advice is shared, encouraging preparedness in case temperatures drop further.
- Yellow: Elevated risk to vulnerable groups such as the elderly or individuals with chronic illnesses. Advice emphasizes extra vigilance and proactive measures.
- Amber: Risk to the wider population. This level typically sees higher demand for NHS services, travel disruptions, and an increased chance of health emergencies.
- Red: Extreme weather with widespread health threats, even for healthy individuals. At this stage, critical infrastructure such as power grids and transport systems can be severely impacted.
Why Does Cold Weather Pose Health Risks?
Science shows that exposure to extreme cold can wreak havoc on the human body by increasing blood pressure, slowing mental processing, and reducing blood flow to extremities. Studies have identified 18°C as a physiological tipping point; below this, your body works extra hard to maintain its core temperature, leading to higher risks for stroke, heart attacks, and other health conditions.
Cold temperatures also exacerbate illnesses such as flu and pneumonia, which tend to thrive during the colder months. The UK’s winter vomiting bug (norovirus) is another common issue during the cold season.
Recent experiments, shared by BBC Inside Health, demonstrated the effects of cold on brain blood flow and metabolic responses, a stark reminder of why adequate heating, proper clothing, and nutritious eating matter so much during winter.
How Are Alerts Communicated?
Public access to these alerts is simple. Those interested can register to receive notifications directly by email. For professionals and institutions, alerts come with guidelines and action plans tailored to mitigate risks. For instance, a national response might include ensuring sufficient heating in homes for vulnerable populations or reallocating NHS resources to handle increased emergency care needs.
How Can You Prepare?
Making changes to prevent the dangers of cold weather doesn’t have to be intimidating. Here are some steps to consider:
- Heat your home efficiently and aim for indoor temperatures of at least 18°C.
- Wear warm layers and focus on keeping your extremities covered.
- Stay active indoors; movement generates body heat and keeps circulation healthy.
- Consume nutritious and energy-providing foods to help your body cope with the cold.

Frequently Asked Questions on Cold Weather Health Alerts
What is a cold weather health alert?
A cold weather health alert is a notification issued by the UK Health Security Agency (UKHSA) and the Met Office when low temperatures bring heightened risks to public health and infrastructure. These alerts aim to prevent cold-related illnesses, such as hypothermia, strokes, and heart attacks, while ensuring systems like power grids and transport networks remain functional. Alerts are categorized into four levels, green (minimal risk), yellow (elevated risk to vulnerable groups), amber (wider population risk), and red (extreme risk), each tied to specific precautionary measures and responses.
Learn more details about the cold health alert system on UKHSA Health Alerts Dashboard.
Why are these alerts issued between November and March?
Cold weather health alerts are restricted to this period because it corresponds to winter months when temperatures typically drop below 18°C, the physiological tipping point for cold-related risks. During winter, illnesses such as flu and pneumonia multiply, and cold snaps can exacerbate pre-existing medical conditions. Between November 1st and March 30th, UKHSA and the Met Office consistently monitor weather patterns for early identification of dangerous cold spells, ensuring vulnerable populations, NHS resources, and infrastructure can prepare adequately.
How are health risks categorized in these alerts?
Cold alerts are color-coded based on risk severity:
- Green: Minimal risk to health; advice on preparation shared.
- Yellow: Elevated risk, especially for the elderly or chronically ill; proactive measures recommended.
- Amber: Health emergencies likely; NHS demands rise and travel disruptions occur.
- Red: Extreme weather; severe health risks even for healthy individuals and threats to power and transport systems.

What precautions can individuals take during cold alerts?
To stay safe during cold weather, aim to:
- Maintain indoor temperatures of at least 18°C, especially in living rooms and bedrooms.
- Wear warm layers that include gloves and socks to protect extremities.
- Stay physically active indoors to improve circulation and body heat.
- Consume energy-rich foods, including hearty soups or warm dishes, to support the body’s metabolic needs.
For additional advice, check out BBC Weather Warnings.
How can you register to receive cold weather alerts?
Registration is simple and open to the public. UKHSA offers an email subscription service where individuals and organizations can opt to receive these alerts directly. Healthcare professionals and government institutions also receive tailored guidelines to mitigate risks for vulnerable populations, such as ensuring adequate heating supplies in homes.
Get alerts directly by checking updates or registering through services like Met Office Weather Alerts.
Why does the human body struggle in temperatures below 18°C?
Below 18°C, the body must work harder to maintain core temperature, leading to physiological effects such as slower brain blood flow, weakened circulation to extremities, and higher risk of strokes and heart attacks. Conditions like norovirus (winter vomiting bug) also thrive in colder weather, increasing susceptibility among vulnerable populations.
