The smell of sun cream, bubble gum and fish and chips have been revealed among a list of 40 scents which trigger nostalgic childhood memories of school days, holidays and loved ones.
The study of 2,000 adults also found freshly mown grass, candy floss and rain on hot tarmac set the senses harking back to years gone by.
Experts found a waft of lavender, peppermint and were most likely to spark memories of their grandmother, while the smell of petrol, musty sheds and Old Spice were likely to prompt memories of grandfather.
The research, commissioned by Disneyland Paris also found more than half of Brits said the aromas of holiday destinations trigger lasting memories.
Additionally the results showed eight in ten of those polled said a whiff of a certain aroma instantly transports them back to a specific memory – more than 70 per cent said those memories were happy ones.
Professor Barry Smith, a sensory expert who worked with Disneyland Paris said: ‘More than any other sense, smell can evoke powerful, emotional memories. Whole scenes of people, places and things can be brought back to life by the mere hint of a long forgotten scent.
‘The rooms in a friend’s house, a boat trip, the sound of a voice, can all be conjured up by smell’s power to reproduce the scenes for us.
‘The top 40 scents show a wide array of things that awaken our senses and stay with us for the rest of our lives.
‘They show the pleasure we take in experiencing smells and the powerful emotions they evoke.
‘Happy memories from childhood are bound up with particular smells, and it is the sense of smell that will preserve our link to them.
‘Whether it’s a seaside holiday, a visit to a fairground or a sunny walk through a forest, suddenly smelling a particular scent can suddenly take us right back there, re-creating the whole sensory experience.’
The influence of childhood memories on us as adults was clear with six in ten saying our early memories affect us powerfully as adults.
Certain smells really do stick – the over 55s were just as likely to associate the scent of candyfloss with fun childhood attractions as were the under 25s.
The power of the senses remains strong despite age – over 55s were just as able to recall memories as the 18-24s.
