1. Multitasking
"Multitaskers might feel like they’re getting more done, but it almost always takes longer to multitask than to devote your attention to one thing at a time," says psychologist Lucy Jo Palladino, PhD, author of Find Your Focus Zone: An Effective New Plan to Defeat Distraction and Overload.2. Boredom
Dull tasks can sap your ability to focus and make you more vulnerable to distractions.
"When you’re bored, almost anything else can be more attractive than what you’re doing," says Gordon Logan, PhD, a psychology professor at Vanderbilt University in Nashville, Tenn.
3. Mental Distractions
When you’re worrying about money, trying to remember if you took your vitamins, and replaying a conversation in your head that didn’t go as planned, it's hard to settle down and stay focused on a project you’re trying to complete.4. Electronic Interruptions
"It’s easy to fall into aiding and abetting in your own distraction by checking your email all the time," Kegan says. "If you’re trying to concentrate, you can lose your train of thought every time you hear 'You’ve got mail'."5. Fatigue
Many studies show that loss of sleep impairs attention, short-term memory, and other mental functions. "Your attention falls apart when you’re sleep deprived," Baime says. Sleep needs vary, but most adults do best with seven to nine hours of nightly sleep. Getting at least seven hours of sleep will go a long way toward improving your focus during the day.6.
