300 years ago, nostalgia was considered a curse of the clinically depressed, but now, it is widely seen as a positive attribute of human
consciousness. It’s simply your brain reacting to a cognitive trigger from some part of your sense memory, or a pro- tective reaction of the brain to boost our spirits when we’re feeling blue.

Each memory tweaks some tiny subset of the neurons in the brain (the human brain has 100 billion neurons in all), changing the way they communicate. Neurons send messages to one another across narrow gaps called synapses. A synapse is like a bustling port, complete with machinery for sending and receiving cargo—neurotransmitters, specialized chemicals that convey signals be- tween neurons

Over the past five years, nostalgic ads have been appearing more frequently in advertising and marketing with millennials as their main target.
Although these ads are getting more common, marketers have known that millennials would be a nostalgia-fueled generation for some time now.

By tracking students over the course of a month, she and colleagues found that feelings of nostalgia were more common on cold days. The researchers also found that people in a cool room (68 degrees Fahrenheit) were more likely to nostalgize than people in warmer rooms.

Not everyone in the cool room turned nostalgic during the experiment, but the ones who did reported feeling warmer. That mind-body link, Dr. Wildschut says, means that nostalgia might have had evolutionary value to our ancestors long before Odys- seus.
