Video Summary: Sleep Essentials (Parts I, II, and III)
Here are the KEY points covered in the videos above. Contact us directly with questions.
• Hours: 7.5 – 9.5
• Quality: 3- vs. 4- Stage Model (Awake, Non-REM, REM vs. Awake, Light Non-REM, Deep Non-REM, REM), Sleep cycles through stages over 90 minutes
• Age: Affected by Stage of Life (Infant, Teen, Adult, etc.). As we age, we sleep less but still NEED the same quantity/quality of sleep
• Circadian Rhythm: Sleep/Wake Cycle, Timing of food consumption, Exercise – our body adapts neuro-endocrine responses based on cyclical aspects of these factors.
• Life Span vs. Health Span: Optimal sleep patterns can positively improve the QUALITY OF LIFE as we age. Improve our HEALTH later into life.
• Reading, Writing – Stimulating activities will adversely affect ability to fall asleep.
• Exercise – Not within 2 hours of bedtime
• Devices – TV, Phones, Tablets, etc. (Blue light, Extraneous light “trick” our body into thinking we are in Daylight, which adversely affects ability to fall asleep d/t Circadian Rhythm)
• Naps – Adenosine, an important biochemical in the body, builds up throughout the day creating “sleep pressure”. This increased pressure allows us to acquire better sleep throughout the night. Naps (especially those 90 minutes or longer) will reduce Adenosine, decreasing the sleep pressure at Bedtime. For those who sleep well this may not be an issue. For those who find it difficult to sleep, naps should be avoided or be short in nature (i.e. 10-20 minutes).
Alcohol – while some may find alcohol helps them “fall asleep”, it also reduces the quality and depth of sleep throughout the night. It is a powerful diuretic and thus will require more voiding of the bladder during the night.
Meal Time – when you eat impacts hormonal levels in your body. To improve sleep quality it has been suggested to avoid eating within 3 hours of your Bedtime.
Caffeine – it is a stimulant and competes for the Adenosine receptors that promote sleep.
After ingesting caffeine 6 Hours later, 50% remains in your system12 Hours later, 25% remains in your systemYour sleep depth and quality will be affected by caffeine even if you feel like you get good sleep. Best to avoid caffeine; it is certainly recommended to avoid it after 12pm if you struggle with sleep
