Part of Margaret Thatcher's formidable reputation was
down to how little she slept. The former Prime Minister was
believed to get by on just four hours of sleep each night and she
was not the only one.

Nikola Tesla, the 'grandfather of electricity' was
thought to sleep for just two hours a night, while Italian
politician Silvio Berlusconi only gets two to four hours, and
Barack Obama six hours. Now, a new infographic reveals some of the
sleeping habits of the world's most successful people, and most are
below the recommended levels of shut eye. Microsoft founder, Bill
Gates, averages seven hours sleep and billionaire Donald Trump only
gets three to four hours.


The National Sleep Foundation
recommends seven to nine hours of sleep a night for 18-64 years
olds to maintain a healthy lifestyle. Despite Thatcher's and
Obama's examples, politicians are the group with the most people
who get more than nine hours of sleep each night. The chart
also shows how people in marketing and PR get the least sleep, with
the sector having the highest number of people who sleep less than
three hours. '"We wanted to compare these individuals against
data from other people working in those sectors." said Made to
Measure Blinds who made the graphic.


The researchers took data from a YouGov survey, which
asked 1,401 working adults about their sleeping habits to create a
chart. People don't necessarily have to get unbroken sleep to get
their rest, however, research last year found that interrupted
sleep can be as physically detrimental as having no sleep at
all.


The study linked interrupted sleep
patterns and compromised cognitive abilities, shortened attention
spans, and negative moods. The researchers at Tel Aviv University
discovered that interrupted sleep is equivalent to no more than
four consecutive hours of sleep. Sleeping well is also linked to
better health, with those who get enough sleep more likely to have
better mental health and less likely to be overweight, develop high
blood pressure, raised cholesterol and Type 2 diabetes.
