Check out this article for the 15 Best Tips for 2025 for Healthier, More Sustainable and Connected Cold Days
Initially, those who live in cold regions or live in cities where winter arrived with force in 2025, have already realized that this year the low temperatures are here to stay.
According to the report of the World Climate Watch 2025, this will be the longest winter of the last decade in South American countries, especially in the south and southeast of Brazil, with peaks of thermal sensation below 0 °C in urban areas such as Curitiba, São Paulo and Porto Alegre.
In short, if before we were content to put on a sweatshirt and drink a hot tea, today surviving the cold requires more: thermal comfort, health, energy savings and even connection with technology.
Therefore, we have gathered the best updated tips for you to face the cold with much more intelligence and care, without sacrificing well-being and sustainability.
1. Invest in smart thermal clothing
Firstly, thermal clothing has evolved a lot by 2025. New fabric technologies with heat-conducting microfibers allow coats and socks to warm the body intelligently, without the need for layers and layers of clothing.
Brands like HeatSense BR and ThermoWear are already popular in the national market, including models rechargeable via USB-C.

2. Use portable heaters with motion sensors
One of the great innovations of 2025 is the compact heaters with presence sensors and app control. They only turn on when they detect movement in the room, avoiding wasting energy. Ideal for those who want to keep the room warm at night without worrying about electricity consumption.
Extra tip: the models SmartHeat Mini and EcoWarm Touch are now available in Brazil.
3. Take care of your skin (more than ever)
With low humidity and constant use of hot water, the skin tends to dry out a lot during winter. In 2025, dermatologists reinforce the use of moisturizers with ceramides, niacinamide and hyaluronic acid.
However, don't forget sunscreen: even on cloudy days, UV radiation continues to act.

4. Adapt your diet to maintain immunity
According to nutritionist Dr. Ana Meira, columnist for the magazine Live Well 2025, eating in the cold should be prioritized thermogenic foods, such as ginger, cinnamon, turmeric and pepper, as well as soups rich in vegetables, whole grains and good fats.
Vitamin D consumption has also become essential in 2025, as cloudier days reduce our exposure to the sun.

5. Reduce the use of electric showers with hybrid showers
With the rise in energy prices in 2025, many people are opting for hybrid showers (solar + electric). They heat water with solar energy during the day and only activate the electric heating element if necessary. In addition, there are models that automatically limit the shower time, helping to save money and preserve the environment.
6. Create cozy environments with warm lighting
The right light changes everything! Swap out white bulbs for warm tone lights (2700k to 3000k), which make the environment more welcoming and reduce the feeling of cold. LED lights with intensity control help regulate the atmosphere of the house according to the time of day.

7. Keep your body active even at home
The cold weather can be discouraging, but a sedentary lifestyle cannot take over. In 2025, indoor training apps like SweatHouse and the Nike Home Move offer quick plans (10 to 20 minutes) that help keep the body warm and circulation active, as well as preventing muscle pain caused by long periods of immobility.

8. Ventilate the house every day (even in cold weather)
Opening windows for 10 to 15 minutes a day helps to freshen the air, prevent mold and mildew, and reduce the spread of respiratory viruses. This practice has become even more important after the viral outbreaks recorded in early 2025, according to the National Environmental Health Agency.
9. Get a respiratory check-up and winter vaccinations
With respiratory illnesses expected to increase in 2025 — including new strains of flu viruses and climate-adapted rhinoviruses — doctors have recommended that adults and children keep their vaccination records up to date and have preventive respiratory exams between April and July.

10. Invest in smart blankets
Bluetooth temperature-controlled blankets are a trend in 2025. They allow you to adjust the heat on each side of the bed, ideal for couples with different temperature sensations. The model DualTemp SmartCover is one of the best sellers in Latin America.
11. Avoid humidity indoors with dehumidifiers
Excessive humidity can worsen allergy attacks, as well as cause mold and mildew. In 2025, compact and quiet dehumidifiers will become more affordable, including those with digital sensors that indicate the ideal humidity level (between 40% and 60%).

12. Reinforce the thermal insulation of windows
Next, replacing curtains with thermal blackout models or applying reflective films to windows can greatly improve the thermal comfort of your home.
In colder regions, it is even worth using sealing tapes to block cold air from entering through gaps.
Extra tip: in 2025, the state government of Paraná started a program to encourage thermal sealing to reduce electricity consumption in winter.
13. Drink more water (even if you’re not thirsty)
In cold weather, we feel less thirsty, but our bodies continue to lose water — especially in dry air. By 2025, hydration apps like WaterMinder gained extra functions, such as alerts based on ambient temperature and physical activity level.
14. Turn the cold into an opportunity for connection
By the way, cold days can also be the perfect time to reconnect with yourself and those around you. Have movie sessions, prepare a homemade fondue, play a game with a group or simply take the opportunity to slow down.
It is worth noting that the “conscious winter” trend gained strength in 2025, with more people valuing time at home as a form of self-care.

15. Show solidarity: donate blankets and clothes
In times of intense cold, small gestures save lives.
In this way, several national campaigns in 2025 have collected warm clothing, food and hygiene kits for homeless people. Get involved! Every city has a collection point and there is always someone in need.
The cold of 2025 may be challenging, but you can beat it with intelligence and care
Finally, in this year when winter has become harsher and longer, it is not enough to just wrap up warm: we need to understand the context, adapt our routine and use technology to our advantage. Taking care of our physical and mental health and the health of the planet is part of the new awareness of well-being that is growing in 2025 and is expected to expand even further by 2026.
With these practical, sustainable and cutting-edge tips, you can not only survive the cold — but also transform this season into your best moment of self-care.
