The Science of Sleep: Understanding What Happens When You Sleep

Sleep is integral to our survival, but most people don’t get the shut-eye they need. According to the National Sleep Foundation, 74% of adults do not get enough sleep. Lack of sleep impairs concentration and increases a person’s risk of obesity and diabetes. However, scientists also have found that lack of sleep causes stress and obesity.

Our bodies need sleep to function, but how much is enough? If you’ve been told that you need seven to eight hours of sleep each night, you may scoff at the idea, but a new study from the National Institutes of Health shows this may not be the case. The study investigated the average sleep needs of young adults and found that, on average, young adults need about seven hours of nightly sleep.

Sleep does a body good, and losing just one night of sleep can have a significant impact on your health. Sleep deprivation destroys your immune system, makes you less productive, and increases your heart disease and cancer risk. But a good night’s rest is more than a matter of physical health: get enough of it and wake up feeling more energized than before, and your mood improves. The problem of sleep deprivation and insomnia has become quite widespread among people in recent years. The problem is that people don’t realize how destructive it can be to their health. So if you fall into this category, you might want to try sleeping aids such as cannabis products (click here to learn more) or melatonin tablets, to get 8 hours of quality sleep.

Sleep is one of life’s most underrated necessities. While you might assume that you can function just fine in just a few hours of shuteye, this can spell disaster for your body. Cortisol, the stress hormone, increases during the night, making it harder for your mind to wind down. This can lead to poor concentration and memory, as well as fatigue.

Sleep: is one of the most mysterious elements of our health and wellbeing. It’s long been believed that sleep is a waste of time and that we’d be better off getting as much done as we can while we can. That view has been challenged in recent years. Scientists have discovered that sleep does a lot more than just allow our bodies to rest and recuperate-there are specific times when our bodies do most of their repair work. Researchers have found that the sleep and waking processes have biological connections that tie them closely together. Sleep and waking are so closely linked to each other that studies have found that sleep and waking are connected by so-called “sleep-wake cycles”-one cycle lasting about 90 minutes.

What Happens When You Sleep?

Your body goes through a lot of changes while you sleep, all of which are crucial for regulating and preserving your health. Sleep deprivation can have serious effects on your health, and your quality of sleep can have a significant impact on your stress levels, weight, and overall health. The average person needs about 7-9 hours of sleep per day. Many things happen when we sleep, but the most important thing is that we rest. When we rest, we sleep. When we sleep, our bodies repair and heal themselves. We wake up refreshed and ready to face the day when we sleep. Sleep helps your body heal, helps regulate your hormones, and increases your alertness during the day.

Sleep is hugely important to our health and wellbeing. But how much do we really understand about sleep? Sleep can be divided into three broad stages: non-REM (or light sleep), REM (or dreaming), and deep sleep. Non-REM sleep makes up 60-80% of sleep time and is mainly responsible for renewing and repairing body tissues, so most adults need between 6-8 hours of sleep per night.

Sleep is hugely important for our health-it’s how we recover from exercise and mental exertion and how we rest our bodies. But sleep doesn’t just come naturally for most of us, and most of the time (68% on average), we’re in REM sleep by 5 am and in a deep sleep by 10 am. For healthy adults, staying awake for 24 hours or longer is unhealthy since sleep is our body’s natural way of healing. So why don’t we sleep? There are a number of reasons, including too much caffeine, anxiety, and depression. But the big one is our internal circadian rhythms which dictate when we should sleep.

You spend a third of your life sleeping, and you probably don’t even realize how important sleep is. It’s important enough that sleep deprivation is actually dangerous. Sleep deprivation can lead to more serious health issues like diabetes, obesity, heart disease, and even depression. So, it’s important to get enough sleep, and the best way to do that is to go to bed at around the same time each night and wake up at the same time each morning.
