Weekend sleep may make up for deficits, but enough sleep every night is better

Share

A study by Swedish researchers suggests that possibly, long weekend sleeps may compensate for short weekday sleeps. The study involved over 43,000 people who were followed for 13 years.

Researchers found that those who slept fewer than five hours a night all week long had a 52 per cent higher mortality rate, or chance of death, compared to those who slept seven hours every night. But if those who had short weekday sleeps slept in on their days off, their mortality rate was the same as those who consistently got seven hours of shuteye.

Those who slept a long, nine hours a night had no higher mortality. The study was published in the Journal of Sleep Research.

Prof. Kimberly Cote says sleep is powerful and everyone should make it a priority.

Consequences for safety and performance

While the study is interesting, it has limitations, says Kimberly Cote, a psychology and neuroscience professor at Brock University and a past president of the Canadian Sleep Society.

She says death is not the only consequence of sleep deprivation, and that no one should conclude from this study that it’s okay to miss out on sleep during the week and make up for it on days off. “When you cut down on your sleep for even one night, there’s negative consequences the next day for your well-being and your performance,” she says.

“Even that one-hour time change in the spring is enough that we see increased auto accidents around the world. So, it’s not a good idea to restrict your sleep. There are consequences for your safety, your performance and your functioning.”

Not everyone needs the same amount of shuteye, but sleeping between seven and nine hours an night is considered optimum for most people.

Sleep as important as food and exercise

Cote says the best advice is for individuals to find out how much sleep they need and then to consistently get that amount. She wishes everyone understood how important sleep is for our well-being. “A good way to think about it is that sleep is as important for your health as diet and exercise. It seems to be the thing that people don’t take as serious.”

She notes that some cultures consider sleep to be a luxury and that people who sleep in are lazy or unproductive. But she says: “We should thing of sleep as a performance enhancer…Sleep is powerful. It’s needed for the totality of your well-being and everyone should make it a priority.”

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.
