AEDs Arrive. Around 1980, the AED (automated external defibrillator) debuted. The 'automated' part is what is really exciting. Now people with only minimal training can successfully revive VF victims in the field, even before Emergency Medical Services personnel arrive.
Sensitivity has many shades of meaning but most relate to your response to your environment â either physical or emotional. Sensitivity to cold means youâre quick to notice the slightest chill â in the air or in another personâs actions. A sensitivity to pollen means youâre sneezing any time itâs in the air â you just always seem to react to it. Itâs the same with emotions â sensitivity means you pick up on the feelings of others.
There can be many medical reasons to feel cold, but it can also just be that an individual has a normal body temperature that is low, and then outside cold temperatures could be more noticeable. There can be hereditary factors. It is also true that adipose tissue (body fat) works as an insulator of body temperature, therefore, if someone has very little body fat and not much muscle, they may feel colder because it is easier for body heat to be lost.
