How Does Caffeine Affect Sleep? | Matthew Walker

Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep.

In this book, the first of its kind written by a scientific expert, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, Why We Sleep delves into everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.

I've been experimenting with quitting caffeine on/off for a while and I can say that caffeine certainly blocks my deeper sleep and dreaming. I have an entirely different kind of sleep when I'm off coffee

“To put into context- accelerating aging by 15-20 years is the same equivalent of losing 20% deep sleep.” Thank you for the great info as always Dr. Walker!

I was drinking one cup of coffee a day at 8am and it still affected my sleep 😢. I love the whole experience of drinking coffee but I think I'm going to have to face the reality that my body just doesn't agree with it.

I drinked 3 cups of coffee today without knowing this, its 5 am now, and I'm still wide awake after trying to sleep for hours. Not going to make this mistake again, thanks for the video.

Considering that he looks pretty good for 46 years old.. he must get pretty good sleep!!

The caffeine in my brain opposes this vehemently!

[KorokuGaming]

I had 2 cups of coffee during the day yesterday (I'm usually caffeine free) & my fitness tracker watch recorded the lowest amount of deep sleep I've had all year. Over a full night only 19% of my sleep time was recorded as deep sleep.

I'll be trying to limit my coffee to before 10am from now on like he states here.

I must be very caffeine sensitive. I rarely drink coffee, but even if I have one cup in the morning before my workout .. it seems to affect my sleep. Trouble falling asleep, racong thoughts. I think I'm not meant to be a coffee drinker..

Just pause the video and appreciate what u see. Colour of each object is complementing each other so well. From the window to the table and lamp on it, His skin hair shirt colour . I think its a deliberately designed to keep us focused on the lesson and not get lost.
Ps: distracted by my observations.

Lots of decaff coffee at your local indie coffee shop tastes great. Lots out there now. Try it!

I didnt sleep last night and thought the title said “How does cocaine affect sleep”

[Glymrl]

What about decaf coffee? I limit my caffeine intake. Sometimes l drink one cup with caffeine. Is it still harmful coffee without caffeine? I have heard that coffee takes away the minerals from the body.
