How sleep works: The reasons why we can't live without it

If you are one of the millions of people who always feels tired, you can blame it on your alarm clock, the industrial revolution and a general lack of understanding about the bodily behaviour. Or, maybe it is because you sleep too long.

It turns out the human body has an internal clock that is so precise, there are many factors that can cause you to wake up tired.

One thing that is known for sure - if you are not hitting every sleep cycle, you are not getting a good night's rest.

Fun Fact: Sleep is actually low budget time travel few hours ahead into the future.

why did i search for this when i was high?

I always wake up minutes before my alarm. So it’s good to know that I’m not depriving myself of sleep from setting an alarm

[alieunscripted]

This was really good and informative. It makes me want to take my sleeping habits seriously - mind you I do feel lousy when I don't get enough sleep. Also, I just keep thinking how incredible God is. Our body, even in the subconscious helps us.

It would do most of us good if someone shut the breaker off at midnight every night.

I've been in a lot of pain this week...but laying down on my side helps a lot. I've gotten 5 days where I've gotten 12+ hours of sleep and it has been glorious!

If there are 24 hours a day, and our body needs at least 8 hours of sleep, it is imperative that people should only work 8 hours a day and not longer than that! Reserve the remaining 8 hours for our lives, family and friends.

Waking up for school during N3 is the shittiest thing school does to me

I would spend 20 hours a day sleeping if I could. So much better than being awake.

I love falling to sleep to a YouTube doc, something with space in it.

For some really good sleep:
1. Work hard
2. Eat good
3. Hot shower
4. Good sex (in this order, well at least for me)
I promise you'll feel so refreshed in the morning. This was me when newly married.

She called me out :| I'm sitting here trying to sleep curious how sleep works

[TeeB]

Just woke up and im still in bed...why do we sleep? Just popped up in my head. 😁

[krishnaSagar]

anyone here who writes down their dreams... I do it, just after waking up because after sometime I forget them..

[nxnijuno]

This is interesting I hope this gives more storage to my brain learning this

[deepakkapurvirtualclass]

In the waking state, thoughts come 'automatically' in our minds. For example, i myself don't know what thought will come into my mind say after 10 minutes, 20 minutes etc. 

When thoughts come automatically to our mind, it 'seems' to us that we have consciouly 'thought' them.

What helped me to overcome insomnia was this book, I have tried everything, but this did work for me, is *how sleep well? of Michelle Peterson in amazon kindle*

[harperleigh]

My theory has always been that if you have to be woken up by an alarm clock you are not ready to get up. Every time I am woken up by my alarm clock I am exhausted all day. I sleep very well so I just go to bed in time that I will wake up before my alarm goes off.

When you are asleep you are simultaneously alive and dead. The only way to know for sure is to let the cat out of the box.

Wonder about the affect of serotonin. This is made in virtually every plant and animal. It has massive benefits, and it may be directly connected to or helped made by our micro biome in the gut during sleep. It may be so important that it's the reason living things sleep.
