Beach holidays might be pegged as the ultimate kind of relaxation, but a new study has revealed how lying around doing nothing could do more harm than good.
Xinran Lehto, a tourism expert from Purdue University in Indiana, investigated the top factors that contribute to a restorative vacation and found that "variation" was key.
"Lying on the beach for many, many days is not the best way to recharge yourself,' she explained. "After a while you get bored and anxious, then you start thinking about work and things at home you need to do. That's not healthy for you."
Lehto urges stressed holidaymakers to pick places with "enough variation of interest and activities that have depth for you to be engaged with".
In her findings she reveals five factors that will contribute to a successful trip.
