Ultimately, despite their huge scope of impacts, heat and cold exposures
are individual phenomena and thus highly relative, researchers have found--from one person, home, neighborhood, city, and region to the next.
Effect of maternal cold exposure
on brown adipose tissue and thermogenesis in the neonatal lamb.
A study published in The New England Journal of Medicine in the late 1970s famously debunked the belief that the common cold is linked to cold exposure
, but British cold researchers have maintained that there is a cold air connection to the common cold.
The objective of this investigation was to determine whether stress (and mortality) caused by cold exposure
can be predicted from a reflex impairment index; therefore, it was important to generate variable levels of cold-related stress that would result in a full range of impairments (0 to 6; see below).
He was one of four climbers who died from cold exposure
Since cold exposure
causes this increase in concentration of thrombogenic factors in the blood of both young and elderly people, it might be expected that it would increase mortality rates in both age groups.
Protection from full sun also means protection from cold exposure
, an important matter in the case of the frost-sensitive Burmese honeysuckle.
Two other factors are extremely high birth weights, which complicate birth, and very low birth weights, which cause sensitivity to cold exposure
elsewhere may be more severe than our balmy shores, but a thick blanket of insulating snow protects much more effectively than our milder winter temperatures.
Women are affected nine times more often than men and it seems to be a change of temperature rather than simple cold exposure
that triggers an attack.
Furthermore, using a different strategy, one experiment in this study demonstrated that the development of cold adaptation was retarded when the contextual cues were changed for each daily cold exposure
, as would be predicted from the associative model.
one of Ember's scientific co-founders, found that inhibition of Aldh1a1 induced classic brown fat characteristics, including increased energy expenditure, protection against cold exposure
, lowered glucose levels and reduced weight gain.
