4. Trying to Wring Even More Hours Out of the Day
We have a very sad fact to share. Brace yourself: Coffee cannot replace sleep.
We know, we know. We’re grieving too.
The truth is that doctors are serious when they tell you to get between seven and nine hours of sleep a night, every night, at least between the ages of 18 and 64. Less than that could affect your productivity and, worse, encourage your arteries to harden.
The importance of sleep cannot be stressed enough.
An article in the Harvard Business Review written by Harvard Medical School professor Charles Czeisler warns us that people who sleep less than five hours a night for five years in a row are three times more likely to develop hardened arteries.
“The importance of sleep cannot be stressed enough,” says Hamilton. “Sleep allows your body to process nutrients taken in during the day and allows your mind to process events of the day.”
There isn’t really a problem that insufficient sleep doesn’t make worse.
“Memory loss and mood disorders such as anxiety and depression have also been linked to sleep deprivation,” Hamilton says.
Even worse, skimping on your Zs can wreak havoc on your genes themselves, leading to DNA damage that raises your risk of cancer. We don’t know how to get more hours in the week either, but it’s clear that skipping sleep is not the way to do it.
