- The Ministry of Health offers a free low-temperature alert system customizable by province and period.
- Notifications provide daily information on risk levels and tips for protecting against extreme cold.
- Intense cold can affect both your health and the functioning of mobile devices, so it's vital to follow official recommendations.
Winter is here , bringing with it low temperatures, a phenomenon that can significantly affect the health, mobility, and safety of the population. Whenever cold waves intensify in Spain, the Ministry of Health activates a low-temperature alert system that allows any citizen to anticipate, protect themselves, and minimize risks associated with extreme cold. This completely free and voluntary service is sent directly to your mobile phone via SMS or to your email address, but requires prior subscription, which takes only a few minutes.
The alert system is part of the National Plan for Preventive Actions Against Low Temperatures , designed to protect public health and reduce the impact of harsh winter weather on vulnerable people, infrastructure, and transportation. This plan includes active risk monitoring, daily updates of temperature and mortality data, and coordination between government agencies to maximize prevention and response to episodes of intense cold.
Why are low temperature alerts on mobile phones important?
Low-temperature alerts not only warn of significant temperature drops, but also notify the associated public health risk levels . These levels are calculated based on specific temperature thresholds linked to increased mortality or the worsening of chronic illnesses, especially among the elderly, children, patients with respiratory or cardiovascular conditions, and the homeless.
Furthermore, extreme cold can cause traffic accidents due to ice, falls on public roads, and domestic carbon monoxide poisoning from the improper use of braziers, stoves, or fireplaces. Therefore, staying informed allows for preventative measures to be taken at home, when planning outdoor activities, or when caring for vulnerable individuals.
How does the Ministry of Health's alert system work?
The Ministry of Health has created an easy-to-use digital platform so that anyone can subscribe to low-temperature alerts . Through a form available on its official website, users can personalize their notifications based on their province and the time period they are interested in. This makes it suitable both for those who usually live in a particular area and for those planning to travel or spend time in other regions.
- Email and mobile number: Upon registration, the user can choose to receive alerts by email or SMS according to their preference.
- Province of interest: The system allows you to select the province for which you want daily, personalized information tailored to actual weather and risk data.
- Subscription period: You can define the date range in which you want to receive the information, which is ideal for those who only require alerts during trips, vacations, or certain times of the year.
Once you complete the form, the system sends a confirmation message (via email or SMS, depending on the option chosen). You must validate this message to receive notifications. If you wish to receive alerts for multiple provinces, you must subscribe to each province.
The notifications received include relevant information such as the expected minimum and maximum temperatures , the level of risk (classified into four categories easily identifiable by colors) and, sometimes, preventive recommendations that help to take immediate action.
- No risk (grey): Normal conditions, no specific warnings.
- Low risk (light blue): Caution, slight risk of health impact.
- Medium risk (medium blue): It is recommended to increase protection and pay attention to health advice.
- High risk (dark blue): Potentially serious impact on health, special attention to vulnerable groups and strict application of official recommendations.
Health and expert advice to protect yourself from extreme cold
The Ministry of Health, supported by scientific organizations and public health experts, has published key recommendations to minimize the effects of cold weather both at home and outdoors. These recommendations should be followed by the entire population, with particular emphasis on at-risk groups:
- Breathe through your nose Outdoors: This simple habit helps warm and humidify the air before it reaches the lungs, reducing airway irritation.
- dress in layers: Wearing several thin layers is more effective than wearing a single thick layer, as the layers trap heat and allow you to adapt to temperature changes.
- Controlled home ventilationIf you use braziers, fireplaces, or any heating system that can emit carbon monoxide, ventilate your home twice a day for at least fifteen minutes to prevent poisoning.
- Healthy nutritionMaintain a varied and balanced diet, drink warm beverages, and stay hydrated. Regular fluid intake helps combat the cold and strengthens your immune system.
- Check the weather forecastBefore you head out or plan any trip, check the weather and adjust your clothing and routines to the current alert level.
- Avoid going out during hours of extreme temperatures and reduces unnecessary physical effort when the cold is intense.
- Wear non-slip footwear to prevent falls in icy areas.
- Do not self-medicate: Some medications can aggravate the effects of cold or interact with the symptoms it may cause.
- Prioritize flu vaccination, especially if you are over 65 or suffer from chronic illnesses.
In addition, it is recommended to pay active attention to people in vulnerable situations : elderly people, patients with chronic diseases, minors and those who may not have sufficient resources to cope with the cold.
How do low temperatures affect mobile devices?
It's not just human health that's affected by the cold. Electronic devices, especially mobile phones , suffer malfunctions in sub-zero temperatures. Lithium-ion batteries experience chemical changes, reducing battery life and potentially causing unexpected shutdowns or a drastic decrease in performance. Similarly, touchscreens can lose sensitivity or stop responding correctly in low temperatures.
- Avoid charging your phone below zero degrees.; the charging process may be inefficient and damage the battery.
- Keep your phone in an inside pocket or thermal sleeve when you are outdoors.
- Don't leave your phone in the car or in places exposed to intense cold.
- In case of abnormal operation, turn off the device and, once at room temperature, restart it.
These tips will help you keep your phone operational and secure even in adverse weather conditions. Responsible use and proper storage ensure alert reception and continuous communication in emergency situations.
Advantages of customizing low temperature alerts
The Ministry of Health's alert system allows for complete customization . You can subscribe only for your vacation period, change provinces depending on your travels, or help family members receive relevant information on their devices. This flexibility makes it easier to protect your health, as well as the health of dependents, the elderly, and children. You can register others following the same process and ensure they also have access to accurate information about extreme cold.
The system's usefulness also lies in anticipating emergency situations: in the event of possible snowfall, frost, or critical temperature warnings, you can adjust your clothing, mode of transportation, or even postpone trips if conditions warrant.
Having a low-temperature alert system on your mobile phone is the best way to stay informed, react quickly, and protect your health against the risks of winter. Remember to keep your information updated in the alert system and always consult official recommendations to minimize the impact of extreme cold on your daily life.
