Another reason for living longer in colder climates is when your colder, the body needs additional mitochondria to warm you up, and mitochondria also slows the aging process.
Body temperature is one of the most well known and important factors involved in lifespan; increased body temperature has been shown to negatively associate with longevity (i.e. earlier death) and conversely, lower body temperature is associated with increased longevity and reduced aging.
It can keep you looking younger.
Cold weather enhances the complexion and rejuvenates skin, Wong says. In a way, it slows down the aging process—think of cryotherapy spa treatments or splashing cold water on your face in the morning—and keeps skin tight, vibrant and radiant.
You're exposed to less sunlight
“Vitamin D and vitamin K levels drop in the winter, and are associated with darker circles under the eyes, giving the appearance of significant aging due to paler, more transparent skin,” explains Patricia Wexler, MD, New York City dermatologist and founder of Wexler Dermatology.
Cold activates a cellular cleansing mechanism that breaks down harmful protein aggregations responsible for various diseases associated with aging. In recent years, studies on different model organisms have already shown that life expectancy increases significantly when body temperature is lowered.
Another study noted that cold showers contribute to the “improvement of the immune system, cardiovascular circulation and vitality,” although proven associations remain unclear. There is also data that suggests showers may decrease inflammation, increase longevity, and improve your metabolism.
Warm Weather is Safer
Studies have shown that death rates are higher in cold climates. People who have easy access to heat & good housing may not be as affected, but for those who are struggling, the winter & cold weather could be a killer.
Exposure to heat can destroy collagen and elastin fibers in the dermis, eventually causing it to become thinner and weaker, leading to premature wrinkling. Heat may also stimulate angiogenesis (new blood vessel growth), which can lead to broken capillary veins, red blotches, and uneven pigmentation.
your skin appears to age faster in the desert). Contrary to a humid climate where the loss of water is replaced by water from the humid air, in the desert your skin pulls water from inside (the dermis) by increasing its Natural Moisturizing Factor (NMF).
Skin that's likely to age faster:
People living in sunny climates are exposed to more UV light throughout the year, even if they do not sunbathe or deliberately seek the sun. There is a cumulative build up of UV damage over the years, even if they never get burnt.
Colder temperatures can act as a tonic or astringent reducing clogged pores and keeping them less visible. Cold weather also slows down and prevents the secretion of sebum, keeping shine at bay and waterproofing your skin and hair. Open pores and less oil means reduced acne as well.
Cold weather clears your pores
Cooler weather can act as a tonic or astringent – reducing clogs and keeping pores less visible and refined. Cold weather also slows down and prevents the secretion of sebum, which waterproofs the skin and hair, keeping shine at bay and reducing acne.
The intense cold causes the blood vessels to contract and tighten, so when the skin returns to normal, the blood vessels dilate back quickly. This sudden flow of oxygen and blood from the face can make the skin look glowier and plump.
In research compiled as recently as two years ago, it was determined that people living in cooler regions of the world may live an average of 2.2163 years longer than those who don't.
Anywhere from 65 to 78 degrees is considered safe. The ideal temperature would be whatever seniors find most comfortable within that range. To prevent an elderly person from becoming too cold, it's recommended the room temperature never drops below 65 degrees.
Cold weather has been shown to dry out your skin and make it more susceptible to wrinkles and other signs of aging.
Naturally dry skin is likely to age faster because the drier the outer skin layers, the less pliable they are. Well moisturised skin is more elastic: “Natural oils and sebum in the skin aid moisture, making the skin appear more plump and moist,” says Alabassi.
“The optimum environmental temperature for skin (and for the human body) is around 64.4°F – 71.6°F. This allows for optimum heat exchange between the body (at 98.6°F) and the outside. “Dry skin is an issue related more to humidity (and dew point) rather than temperature itself.
The researchers found that by the tender age of 45, people with a faster pace of "biological aging" were more likely to feel, function and look far older than they actually were. And that relative sprint toward old age began in their 20s.
For example, the team suggests that the biological aging process isn't steady and appears to accelerate periodically — with the greatest bursts coming, on average, around ages 34, 60, and 78.
A woman's sexual desire is said to 'peak' from the ages of 26 to 32, while men are at their horniest at 18. For women this is probably linked to a general boost in confidence and sexual experience, though, rather than any major changes in hormones.
Finally, there's also research to suggest that your immune cells are more sluggish in cold temperatures than in warmer temperatures, which is why feeling cold or spending time in cold weather is more likely to make you sick.
The human immune system can be activated when exposed to the cold [2] and this enhances your ability to fight infections. Practising sport, or walking, in winter can help to reduce your likelihood of contracting illnesses as a result of this.
