Sleep, Focus and Cognitive Performance

Do you wake up feeling exhausted?  Or have trouble concentrating at work? Or maybe your tolerance levels area lower than usual. It might be you are not getting enough sleep.

Cognitive performance is our ability to utilise the knowledge acquired by the mental processes in our brains. A well-functioning brain controls a range of voluntary and involuntary actions, such as our sleep-wake cycle, attention, perception, mood, emotions, hunger and memory.

When you lose sleep, it interferes with the functioning of certain brain areas and people who are exposed to Sleep Deprivation usually experience a decline in cognitive performance, changes in mood, decreased reaction times, loss in free recall and in facial recognition.

While losing sleep here and there won’t have much affect, ongoing loss of sleep can have a big impact over time, and can impair our ability to do well in school, at work, and in our daily life. Sleep Deprivation can make it significantly harder to focus, and pay attention and be productive.. This affects school performance and job productivity.

A lack of sleep can also slow your reaction time, which makes for dangerous driving and other safety related risks at work and at home. This can put not only your life in danger, but others as well.

We also need a good sleep to achieve our best innovative thinking and problem solving abilities. As you sleep, memories are reactivated, connections between brain cells are strengthened, and information is transferred from short to long-term. Without enough quality sleep, we can easily forget new information, old information and even memories. Getting a good night’s sleep can be crucial for school and university students throughout their semesters.

If you’re having trouble with any of the cognitive abilities mentioned above, you maybe not getting enough sleep.  Work at increasing the hours of sleep you get a night. Everyone is different as to how many hours you should get. We have lots of tips on how to improve your quality of sleep in our Ritualize program, with an entire Quest dedicated to it and a Learn section within the app accessible at all times. Check it out and set yourself the challenge of increasing the hours you get a night, and see if you notice any improvements in your work, school and daily life. Good luck!

Binge-watching before bedtime…

Are you guilty of it?

Since the introduction of streaming companies, such as Netflix and Stan, the era of scheduled programming has seemingly come to an end. Everyone can watch the content they like when they like. This unprecedented access has introduced a new viewing style: Binge Watching. Binge watching is defined as “watching multiple consecutive episodes of the same television show in one sitting on a screen, be it a television, laptop, computer or tablet.”

Prior research has indicated that media bingeing was associated with more anxiety, depression, and fatigue. Binge viewers also reported higher levels of loneliness and depression. In more recent studies, conducted by the Journal of Clinical Sleep Medicine, it was reported that binge-watchers had more fatigue, insomnia symptoms, poorer sleep quality, and feeling more alert before going to sleep. Those who binge-watch before bed had 98% more chance of having poor-quality sleep than those who didn’t.

Looking at bright screens, especially at night, can wreak havoc on your biology, because it is one of the cues that helps maintain our circadian rhythm, or body clock. When it gets dark, our bodies start to prepare for sleep, but bright lights can trick our brains into thinking it’s still daytime and it reduces our ability to secrete melatonin, which makes it not only harder to fall asleep, but also reduces the amount of sleep you get once you do fall asleep.

While we don’t expect you to stop watching shows, there is a way to help combat the binge-watching addiction. Dr Robert Oexman, a member of the American Academy of Sleep Medicine, says the best way to do it is on the weekend, and earlier in the day instead of the late evenings. Ideally, binge-watching should occur before 6 pm, and if that’s not possible, you should at least stop watching shows an hour before you start getting ready for bed.

Why Sleep is so Important

Sleep plays a vital role in good health and well-being throughout your life. Getting enough quality sleep at the right times can help protect your mental health, physical health, quality of life, and safety.

The way you feel while you’re awake depends in part on what happens while you’re sleeping. During sleep, your body is working to support a healthy brain function and maintain your physical health. In children and teens, sleep also helps support growth and development.

The damage from sleep deficiency can occur right away, or it can harm you gradually over time. For example, ongoing sleep deficiency can raise your risk for some chronic health problems. It also can affect how well you think, react, work, learn, and get along with others.

The amount of sleep you need each day will change over the course of your life. Although sleep needs vary from person to person, the chart below, from sleepfoundation.org shows general recommendations for different age groups. The recommendations are the result of multiple rounds of consensus voting after a comprehensive review of published scientific studies on sleep and health.

AgeRecommended Amount of Sleep
Infants & Newborns16–18 hours a day
Preschool-aged children11–14 hours a day
School-aged children9 – 11 hours a day
Teens8–10 hours a day
Adults (including the elderly)7–8 hours a day

To improve your sleep habits, it may help to:

  • Go to bed and wake up at the same time every day. For children, have a set bedtime and a bedtime routine. Don’t use the child’s bedroom for timeouts or punishment.
  • Try to keep the same sleep schedule on weeknights and weekends. Limit the difference to no more than about an hour. Staying up late and sleeping in late on weekends can disrupt your body clock’s sleep–wake rhythm.
  • Use the hour before bed for quiet time. Avoid strenuous exercise and bright artificial light, such as from a TV or computer screen. The light may signal the brain that it’s time to be awake.
  • Avoid heavy and/or large meals within a couple hours of bedtime. (Having a light snack is okay.) Also, avoid alcohol before bed.
  • Avoid nicotine and caffeine (including caffeinated drinks, coffee, tea, and chocolate). Nicotine and caffeine are stimulants, and both substances can interfere with sleep. The effects of caffeine can last as long as 8 hours. So, a cup of coffee in the late afternoon can make it hard for you to fall asleep at night.
  • Spend time outside every day (when possible) and be physically active.
  • Keep your bedroom quiet, cool, and dark (a dim night light is fine, if needed).
  • Take a hot bath or use relaxation techniques before bed such as meditation.
