Is it healthier to live in colder climates?

Winter can be brutal, but research shows you might get some health benefits during the colder months. When it’s cold, your body has to work harder to maintain its core body temperature — and as a result, you might burn more calories. Colder temperatures can help reduce both allergies and inflammation.

According to the genetic bottleneck theory, between 50,000 and 100,000 years ago, human populations sharply decreased to 3,000–10,000 surviving individuals.

Does cold slow aging?

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.

Warm, dry, sunny weather without excess heat or cold is immensely beneficial for our mental health.

Is your blood thinner in warmer climates?
