Everyone wants to find the secret to a longer, healthier life. Researchers may have uncovered a simple trick you can do right at home, which can potentially extend your life by several years. The tip? Turn down your thermostat.
While it might sound too good to be true, there’s solid science behind this claim. Cold temperatures have been observed to stimulate reactions in skin and fat cells, potentially boosting life expectancy. This effect is primarily due to the activation of a receptor known as the TRPA1 channel.
How the Cold Affects Longevity
TRPA1 channels are found in skin and fat cells and transmit calcium to cells when activated. This calcium influx initiates a signaling chain that eventually reaches a gene called DAF-16/FOXO, which is associated with longevity. DAF-16/FOXO regulates a wide range of genes involved in various aspects of cellular life, including stress resistance, energy metabolism, and cell survival.
So, it seems that exposure to cold air could promote longevity by stimulating this gene. Shawn Xu, a researcher at the University of Michigan Life Sciences Institute, has explored this possibility in his studies. He notes that their findings raise the intriguing possibility that exposure to cold air – or even the pharmacological stimulation of the cold-sensitive genetic program – could promote longevity in mammals.
Of course, no simple trick will guarantee a longer life. However, understanding how cold exposure might work to promote longevity can pave the way for potential breakthroughs in promoting healthier, longer lives.
Brown Fat, Cold, and Health
According to Harvard Health, our bodies house a type of fat called brown adipose tissue (BAT), or brown fat. Unlike white fat, which stores excess calories, brown fat generates heat, helping us to stay warm in cold environments. Researchers have discovered that people with higher amounts of brown fat also tend to be leaner and have healthier blood sugar levels.
Activating brown fat in the body seems to have many benefits. Cold exposure can increase energy expenditure by increasing the activity of brown fat, which could potentially reduce fat mass and lead to weight loss. Furthermore, lower temperatures appear to stimulate the formation of new brown fat cells. So, even if it’s uncomfortable at first, turning down your thermostat might be prompting your body to make more brown fat, contributing to your overall health.
The Benefits of Cold Exposure
Cold exposure has also been linked to improved sleep quality, increased calorie expenditure, and a stronger immune system. Here are some ways to incorporate cold into your daily routine to potentially improve your health:
Cold Showers
Taking a cold shower has been shown to help improve blood circulation, reduce muscle inflammation after intense exercise, and even boost your mood. Start with lukewarm water, and gradually decrease the temperature until it feels cool and refreshing.
Cold Weather Exercise
Engaging in moderate exercise outside during colder temperatures can offer a range of health benefits including increased focus, decreased inflammation, and potentially promoting better metabolic function. Wrap up warm and enjoy the crisp outdoor air.
Ice Baths or Cryotherapy
While ice baths and cryotherapy have gained popularity among professional athletes, they’re not just for the pros. They can also help promote overall health and wellbeing by reducing inflammation and muscle soreness, improving blood circulation, and even boosting your metabolic rate. However, always proceed cautiously and consult with your doctor before starting any new health regimen.
Sleeping in a Cooler Environment
Setting your thermostat to a cooler temperature at night not only potentially promotes longevity but also helps improve sleep quality. According to the National Sleep Foundation, the ideal temperature range for optimal sleep is between 60 and 67 degrees Fahrenheit (15.5 to 19.5 degrees Celsius).
The Bottom Line
While completely guaranteeing a longer, healthier life is impossible, incorporating cold exposure into your daily routine shows promising potential. By activating specific genes and promoting the production of brown fat, cold temperatures might provide your body with numerous health benefits that contribute to improved longevity. So go ahead, turn down that thermostat, and begin to explore the world of cold therapy for better health and wellness.
