What Happens When We Sleep?

When we fall asleep, our bodies enter into a series of sleep stages that cycle throughout the night. These stages include non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. During NREM sleep, our bodies work to repair and restore physical and mental functions, while REM sleep is when our brains process emotions and memories. The sleep stages cycle in a pattern that repeats approximately every 90 minutes, with the majority of the night being spent in NREM sleep and the later stages of the night dominated by REM sleep.

Why Sleep is Important?

One of the most important functions of sleep is physical restoration. During NREM sleep, our bodies produce growth hormone, which helps repair and build tissues. This is particularly important for muscles and bones, which require time to heal and grow. Additionally, sleep is necessary for the production of cytokines, which help the body fight off infections and inflammation.

But sleep is also crucial for our mental health and well-being. REM sleep plays a role in processing emotions and memories, allowing our brains to consolidate and store information. Without enough REM sleep, we may struggle with memory formation and retention. Lack of sleep has also been linked to depression, anxiety, and irritability, as well as decreased cognitive function and problem-solving skills.

Getting Enough Sleep

So, how much sleep do we need to reap these benefits? The National Sleep Foundation recommends that adults get 7-9 hours of sleep each night. Children and teenagers require even more sleep, with infants needing up to 17 hours and teenagers needing 9-11 hours. Of course, these are just guidelines, and the amount of sleep each individual needs may vary.

Tips for Better Sleep

If you're having trouble getting enough sleep, there are several things you can try. Establishing a regular sleep schedule, avoiding screens before bedtime, and creating a relaxing bedtime routine can all help improve the quality of your sleep. Additionally, avoiding caffeine, alcohol, and large meals close to bedtime can also help you fall asleep faster and stay asleep longer.

In conclusion, sleep is a vital part of our overall health and well-being. By understanding the science behind sleep and its importance, we can work to get the quality and quantity of sleep our bodies need to function at their best
