What Does Your Body Do When You’re Asleep?

Spotlight on Sleep Health – Remember when you were a kid and would resist bedtime like sleeping was some kind of punishment? But then you’d wake up the next morning feeling like you just won the lottery? Well, turns out, there’s a lot going on while you’re sound asleep. Yes, your body is like a bustling city of activity where every little cell has a job to do.

Cleaning Crew:

Your body doesn’t just switch off once you close those eyelids. It continues to burn calories and use up energy to perform essential tasks. One of those is clearing out cellular waste that accumulates throughout the day. While you’re asleep, the brain basically checks into cleanup mode where it flushes out toxins and debris.

Think of it as a housekeeper coming in to tidy up your brain and leave it spick-n-span for the next day.

Growth Spurt:

If you’re a gym junkie, you might want to pay attention to this one. While you’re in deep sleep, your body releases Growth Hormone (GH) which is responsible for repairing and rebuilding tissues that have undergone wear and tear. This is why it’s important to get a good night’s sleep if you want to gain muscle or recover from an injury. GH is also crucial for bone growth and maintaining a healthy immune system.

Basically, sleep is the ultimate supplement.

Immune System Boost:

Sleep deprivation doesn’t just leave us feeling groggy and irritable, it can also weaken our immune system. Our body needs rest to produce and release cytokines that are essential for fighting off infection, stress and inflammation. So, the next time someone tells you to “sleep it off,” you’ll know it’s actually good advice!

Memory Lane:

Have you ever had trouble remembering something and been told to “sleep on it”? Turns out this is sound advice. Research shows that sleep plays a crucial role in consolidating memories, that is, turning short-term memory into long-term memory. When you’re asleep, your brain is busy replaying the day’s events and storing them in the appropriate parts of your brain.

This is why people who suffer from sleep deprivation may also experience memory loss.

Calming Down:

Ever notice how you are grouchy and irritable when you are sleep-deprived? One of the reasons behind this is that sleep plays a key role in regulating mood. When you are sleep deprived, your levels of cortisol (the stress hormone) goes up, leaving you feeling anxious and on edge.

Sleep also allows your brain to recharge and reset, leaving you feeling refreshed and ready to take on the day.

Hormone Havoc:

Ladies, listen up! Sleep can play a huge role in regulating hormones like oestrogen and progesterone. When you don’t get enough sleep, these hormones can become imbalanced, leading to a host of health problems including irregular periods, PCOS, and even fertility issues.

If you’re trying to conceive, make sure you’re catching those Z’s.

While we may not be eating while we’re asleep, our body is still working hard to digest the food we consumed earlier in the day. Our digestive system slows down, allowing it to focus on absorbing nutrients and preparing for the next day’s digestion.

A good night’s rest can actually help prevent digestive issues and keep our gut healthy.

Ditching the Bad Stuff:

Quite often we may have some pretty wild and vivid dreams while we sleep and they actually serve a purpose. Our dreams help us to process and let go of emotional stressors, negative thoughts and experiences. It’s important to note that dreaming occurs during the REM (Rapid Eye Movement) stage of sleep, so don’t cut your snooze time too short or you may miss out!

As you can see, there’s a lot happening inside your body while you’re dreaming away. Sleep is essential for our overall health and wellbeing, and our body sure knows it.  So, the next time you lay your head down to sleep, remember that your body is hard at work repairing, regenerating and preparing for the day ahead. It’s amazing to think of all the wonderful things our body is capable of and how beneficial a good night’s rest can be.

Next time someone tells you to “sleep on it”, take it from us, they’re not just being dismissive, they’re giving you sound advice. Happy snoozing!

Wishing you good nights & days ahead.
