Donald Trump, Marissa Mayer, and other big bosses are sleeping all wrong, according to a new McKinsey report

We're often in awe of the highly successful people who say they only get a few hours of sleep a night, from $4 and $4, who clock around four hours, to $4 and $4, who get closer to six.

We might conclude that somewhere within their sleep deprivation lies the key to success.

But $4 by McKinsey researchers suggests that these people are successful in spite of their sleep habits.

According to the report, sleep deprivation negatively affects four key leadership behaviors and, consequently, can hurt a business's financial performance:

1. Being focused on results

$4 points to $4 that shows how sleep deprivation is comparable to intoxication in the way it impairs cognitive abilities.

The individual performance on a range of tasks of people who are awake for 17 to 19 hours, for example, is equivalent to that of a person with a blood alcohol level of 0.05%, the legal drinking limit in many countries.

Beyond 20 hours of being awake, the same person's performance is comparable to someone with a blood alcohol level of 0.1%, which meets the legal definition of drunk in the US, the report says.

To be results oriented, the report suggests, you need to be able to focus, avoid distractions, and see the bigger picture, something that would be very difficult to do if you were essentially drunk on the job.

2. Solving problems effectively

The McKinsey report points to other studies, which find that $4 leads to new insights, $4 help creative problem solving, and $4 is directly linked to creative thinking, all of which are key in effectively solving problems.

3. Seeking out different perspectives

Sleep affects all three stages of the learning process: before learning, it helps your brain encode new information; after learning, it helps your brain consolidate information and form new connections; and before remembering, it helps to retrieve information from memory, researchers say.

"These processes are critical to the ability to seek, encode, and consolidate different perspectives," $4

According to the researchers, sleep $4 to improve decision making in situations that involve weighing different options and avoiding tunnel vision.

"$4 the commonly heard advice that rather than making an important decision or sending a sensitive email late at night, you should sleep on it," $4.

4. Supporting others

The report points to more research that suggests sleep deprivation negatively affects your emotional state.

When you lack sleep, your brain is $4 misinterpret facial or vocal cues and overreact to emotional events. You're $4 express your feelings in a more negative manner and tone of voice. $4 to fully trust someone else. And when you're the boss, your employees $4 to feel engaged with their work.

It's hard to support others emotionally when you're struggling with your own emotions.

All four of these behaviors add up to high-quality executive teams, and as a result, are a strong predictor of a robust bottom line, the McKinsey researchers say. When they are compromised, leaders and their companies suffer.
