You really CAN get out of bed on the wrong side, a survey has found. A poll of 2,000 adults found those who get out on the right side of the bed are more likely to wake up feeling tired and grumpy than those who get out of bed on the left. People who get out of bed to the right also take longer to shift their bad mood and are more likely to see their work affected by their tiredness. The survey also found nine in ten Brits wake up still feeling tired on three mornings a week, with the average adult saying it’s almost 10am before they start to feel properly awake. Having a bad night’s sleep is the most common cause of morning grumpiness followed by stress, waking up earlier than you need to and wet or cold weather. A spokesman for Spatone, which commissioned the research, said: “When you are obviously tired and grumpy, one of the first things people will ask you is whether you got out of bed on the wrong side.
