To celebrate healthy sleep and help others learn about sleep’s vast importance, World Sleep Society hosts an annual awareness day in March, World Sleep Day.

World Sleep Day 2020
 

March 13, 2020. The slogan is “Better Sleep, Better Life, Better Planet.”
 

World Sleep Society created what they call the “10 Commandments of Sleep Hygiene for Adults” back in 2008 and they still hold true today. Follow these 10 Tips for Better Sleep from World Sleep Society.

How much sleep do we really need?

If you are a teenager or young adult you may be surprised. It is recommended that teenagers (14-17) sleep between 8-10 hours, however it may be appropriate for them to sleep as much as 11 hours. Young adults (18-25) are recommended to sleep 7-9 hours however, it also may be appropriate for this age group to sleep 11 hours. Older adults (26-64) are also recommended to sleep 7-9 hours, however it may be appropriate for this group to sleep 10 hours.
 

If you are not waking up refreshed or regularly feel tired and sleepy during the day (or when you should be awake and alert) it is helpful to see how you respond to different amounts of sleep. Try sleeping an extra hour or more each night for at least two weeks. If you do not feel any better see your doctor as soon as possible. Information about your day to day activities including sleep habits can help your doctor identify the underlying cause/s. The National Sleep Foundation (USA) has a great sleep diary you can use to track your sleep and daily activities. Click here to check it out. 

World Sleep Day 2019


March 15, 2019. The slogan: “Healthy Sleep, Healthy Aging.”

“Getting good quality and quantity of sleep is one key to aging well, improving the odds of physical, cognitive and emotional health. Getting good sleep in young adulthood and middle age reduces the risk of obesity and hypertension, protects against age-related cognitive decline and Alzheimer’s Disease, and has been associated with decreased rates of depression. In some studies, regular sleep has even been associated with fewer signs of aging in facial skin and better tissue tone. Look better, feel better, be better. There is a lot to be said for giving good quality sleep a high priority in our daily lives.”- Dr Timothy I. Morgenthaler, MD is a Professor of Medicine and Co-Director of the Mayo Clinic Center for Sleep Medicine.
 

Sleep hygiene. How do those two words translate into a great night’s sleep? 

“Good sleep hygiene means making sleep a priority and following daily routines that allow you to do so,” explains Liborio Parrino, MD, Associate Professor of Neurology at Parma University, Italy and chair of the 2018 World Sleep Day Committee. “Simply put, good sleep habits can cause good sleep quality. And studies have shown quality of sleep is even more important that quantity of sleep.”

World Sleep Day 2018
 

The 2017 Nobel Prize in Physiology or Medicine was jointly awarded to Jeffrey C. Hall, Michael Rosbash and Michael W. Young for their “discoveries of molecular mechanisms controlling the circadian rhythm”.

This Nobel Prize is an exciting acknowledgment of sleep research that will hopefully lead to answers for those living with circadian rhythm sleep disorders. To honour this great achievement the slogan of World Sleep Day 2018 is ‘Join the Sleep World, Preserve Your Rhythms to Enjoy Life’. The goal is to raise awareness of the importance of circadian rhythms in healthy sleep.

What is the circadian rhythm and why is it important to preserve regular circadian rhythms?

Circadian rhythms refer to a cycle within the body. Our circadian control genes that create cellular oscillations affecting cell function, division and growth, along with critical physiological functions such as behavior, hormone levels, sleep, body temperature, immune responses and metabolism. When these rhythms are disrupted, we see increased rates of cancer, diabetes, obesity, heart disease, depression and many other diseases.

 

The circadian rhythm plays such an integral part in sleep health. Preserving regular circadian rhythms have been found to lower the risk of sleep disorders, mental health disorders and chronic health issues. Sound sleep is one of the three pillars of good health along with a balanced diet and regular exercise. Individuals who get an entire night’s sleep without any interruptions experience lower rates of high blood pressure, diabetes, obesity and other chronic illnesses.
