Why having a restful weekend can actually leave you feeling WORSE on a Monday morning Hectic weekends feel six hours and 19 minutes longer It is because we measure time by gaining memories Study for online tickets shop polled 2,000 people Having a 'lazy weekend' may seem like the best way to unwind - but it makes us even more stressed. The average jam-packed weekend feels precisely six hours and 19 minutes longer than one spent on the sofa, a new poll has claimed. It is because we measure time by packing in memories - so the more we do, the longer the weekend seems. Lazy: But a weekend spent in bed or on the sofa can make us feel even more stressed on Monday because it seems shorter, a new poll has found A third of people who crammed social events into their schedule felt like they had three days off. Yet among those who had a lazy weekend, almost half - 43 per cent - said they had not had enough time away come Monday. TV neuroscientist Dr Jack Lewis, a regular guest on ITV's This Morning, said: 'How long a weekend seems to last is measured by how many memories spring to mind when we look back. If looking back at the weekend triggers a torrent of memories of being in new places, having exciting experiences and doing unusual things then this creates the perception that the weekend seemed very long - it must have been to pack in all those activities, right? If you think back to the weekend and no memories of note spring to mind because you had a restful but dull couple of days, then it can seem like it passed in the blink of an eye. TV neurologist Dr Jack Lewis: 'How long a weekend seems to last is measured by how many memories spring to mind' Living for the weekend: Watching a sports match is tiring but it makes you more motivated in the long run, according to a poll of 2,000 people for a tickets shop The study polled 2,000 people for the ticket sales website StubHub. General manager Brigitte Ricou-Bellan said: 'Time flies when you're having fun, but it's really interesting that the opposite is true when you look back at your weekend. Filling your weekend with different things to see and do - from live concerts to sporting events - really can make you feel more rested come Monday morning. The poll claimed 21 per cent of people who saw friends, went to gigs and concerts or watched sport felt like they had a 'proper holiday'. Going out left half of people happier, 28 per cent of them more rested and a fifth of them more positive when they returned to their desks. But keeping busy does not do much for our workload. The research found only one in ten people actually felt more productive after a busy weekend - probably the result of all that alcohol.
