We all know how good it feels to get a good night’s sleep.
That’s because getting sleep is much more than just rest. It’s an essential biological process that allows our bodies and brains to rest, repair, and recharge, directly impacting our moods, cognitive functions and overall health.
Recent studies are allowing us to better understand the powerful effect sleep has on both our mental and physical wellbeing, which directly influences our daily productivity, emotional resilience, and long-term health.
The science behind sleep
According to the National Sleep Foundation, sleep serves as the body’s natural repair system, allowing crucial processes that don’t occur at any other time during the day.
During sleep, our brains consolidate our memories from the day, clear metabolic waste, and strengthen neural pathways essential for learning and decision-making.
The Australian Government’s Sleep Health Foundation backs this up, saying these processes are so important, that even a slight lack of sleep can significantly impair our ability to think and make decisions the next day.
Our physical abilities are affected just as much.
Good sleep gives our body the chance to strengthen our immune function, regulate the hormones responsible for hunger and stress, and repair our cells throughout our bodies.
So, it’s no surprise that people who get good quality sleep show better physical health, have lower rates of cardiovascular disease, and are better at managing their weight.
Sleep and our mental health
We all know how grumpy and tired we can be if we’re not getting enough sleep.
Sleep’s impact on mental health cannot be overemphasised. It has a huge influence on our ability to regulate our emotions, be resilient in times of stress, and effects our general psychological wellbeing.
During deep sleep, our brains process our emotional experiences by consolidating good memories and diminishing the intensity of negative emotional associations.
Proving that when something has upset you or given you stress, it’s always good to sleep on it.
The benefits go far beyond mood regulation.
Quality sleep enhances our attention span, improves problem-solving abilities, and boosts creative thinking.
This happens because sleep allows our brain to form new neural connections and strengthen existing pathways, essentially upgrading our mental processing power each night.
