The new formula has been revealed by package holiday provider easyJet Holidays and Doctor of Happiness Andy Cope to help Brits capture every ounce of holiday happiness this summer.

Alongside sunshine, sleep and physical activity, research found for holiday happiness we need 3.9 hours away from our screens to help lower stress.

The research lifts the lid on when a holiday truly gets underway, with one in five (19%) saying they are in holiday mode as soon as their ‘out of office’ is on, while over a quarter (27%) believe it is from the moment you leave the house and almost one in 10 (8%) believe it is when you reach your destination.

And it takes Brits an average of two days to fully ‘switch off’ from work while on holidays, according to the study, with 4% even taking 7 days or more to truly wind down.

Dr Cope suggests that holiday happiness can be multiplied by the power of p, people, saying the optimum mix is 70% family time and 30% me time. Quality beats quantity, with the Happiness Doctor revealing that it’s not how much time you spend with loved ones, but how present and relaxed you are during it.

He also recommends nine hours of rest per day, three litres of water to improve overall brain function and mood and a small daily indulgence of a sweet treat by the pool – because you are on holiday after all.

In addition to the happiness formula, the top 10 holiday activities that make British holidaymakers happy have also been revealed:

Dr Andy Cope says: “Most people are living life fast, but we’re not necessarily living it well. Holidays give us all a chance to rest, rejuvenate and come back fully charged. Human brains are great at pre-living and re-living, which means we can start enjoying the holiday the moment it’s booked, and retain our happiness glow long after we get back.

The happiest holidays aren’t about ticking off sights, they're about feeling relaxed, present, and a little bit more like ourselves. My prescription for holiday heaven: aim for 25°C-ish, with sunshine, a light breeze, lovely people and zero emails.”

Stuart Wright, Customer Director at easyJet Holidays said: “At easyJet holidays, we believe the secret to a truly happy holiday lies in simplicity, inspiration, and ease. When you travel, you want to focus on what really matters –discovering new places, spending quality time with loved ones, and enjoying a well-deserved break from everyday life.
