As most of you have heard, sleep is vital to a person’s well-being. A person’s mental health is bidirectionally connected to sleep which means that they go hand in hand. Sleep during the night is the body’s time to recharge and give itself some necessary maintenance. After a person has had a good night’s sleep they should be more resilient, calmer and more creative while having better problem solving and decision-making skills. On the other hand lack of sleep can lead to unfortunate consequences such as poor concentration, fatigue, increased irritability or worse.
Lack of sleep disrupts the brains emotional regulation system, especially the amygdala which is responsible for fear and stress related responses. This balances out by the prefrontal cortex which prevents overreactions when well-rested. Otherwise, a sleep-deprived person can become irritable and have increased anxiety. The stress hormone is lowered when a person is well rested while the brain recalibrates the nervous system lessening activity linked to anxiety. Deep sleep can help release mental tension, build resilience and allow a person to cope with different pressures without feeling overwhelmed.
Cognition is the skill that allows us to think, learn and solve problems which is highly dependent on sleep. It is how we process information that we’ve accumulated throughout our waking hours helping short-term memories become long-term memories. The brain’s memory center replays those recent experiences before transferring them to long-term storage. Sleep is what allows our mind to turn memories into broader narratives that make it possible to use understanding and creativity to our utmost advantage. This basically means that our minds are able to find connections between different ideas that can increase innovative and imaginative possibilities. If our sleep suffers, so does our ability to learn and work well.
Our quality of sleep can also be a make or break for our overall attitude and mindset. The right amount of rest is what regulates the mood, lowers stress and increases problem solving abilities. Lack of sleep could be the reason behind lack of attention and concentration. So, in other words, driving while sleep deprived isn’t any better than driving drunk so avoid it however and whenever possible.
Sleep can also help emotions to be processed properly. It can be a way for emotional experiences to be thought through in a safe environment. It can be an excellent benefit to the healing process of heartbreak, traumatic and stressful events. Depression and anxiety are at higher risk to those who are suffering from lack of sleep. Being able to manage and understand any and all emotions can be made more difficult when a person isn’t rested. The ability to access empathy and perceive necessary social cues.
As you have probably noticed, it is harder to motivate yourself when you’re feeling tired. This is because the brain’s reward system depends on sleep to function properly. Without sleep, you lose your drive to achieve goals and give focus to our priorities. We need to be able to give the best of ourselves to everything we do.
Sleep deprivation increases rumination, which is the tendency to dwell on problems and replay worries. This basically means that negativity increases when exhaustion arises. Once sleep is given the chance to soothe emotional circuits and restore cognitive control a person is able to think clearly and rationally. Sleep is probably what allows people to reset their minds for the better.
There are ways to improve the quality of your sleep to prevent the consequences mentioned. For starters, keeping yourself on a steady sleep schedule can help your body stay actively consistent throughout the waking hours of the day. This basically means going to bed around the same time each day and vice versa. It will benefit how and when your body works properly and when it’s ready for rest. This way your body’s internal clock doesn’t get confused. Stability is important for anything to function properly so why would sleep be any different.
It is also beneficial to make sure your bedroom has a peaceful atmosphere so your body can remain at restful and at ease When noise remains active, upbeat and loud your body remains alert and disrupts the body’s sleeping process. You should never underestimate the importance of the right atmosphere for the right time of day. Birds chirping in the morning can represent the dawn of a new day. Up tempo music sends the body signals to activity and movement. On the other hand, soft sounds can calm the mind.
As you may have been warned, phone usage before bed can be bad for your sleep. The artificial light that comes from the cell phone along with other electronic devices can easily keep you more alert making it harder for you to fall asleep. Not only that but the artificial light can decrease levels of melatonin which is the sleep hormone which helps control the cycle that decides when the body is asleep and awake. When your body doesn’t have enough of it will keep you awake at night and tired during the day. Your body will be confused about what state it should be in. That is why phones should be put away at least thirty minutes to an hour before sleep just to be cautious.
People drink coffee for the energy it gives them. People may make the mistake of drinking too many cups. That can and will cause them to have too much energy to be able to stay calm long enough to sleep. That means avoiding anything brings hyperactivity like sugar energy drinks, caffeinated drinks and alcohol. You may not like it, but you’ll thank yourself later.
As you have learned, sleep is very important for the ability to think clearly. There are many reasons why this is beneficial and like other things in life there are consequences without it. We all need to recharge and allow our body to take care of itself. We just need to prioritize how we spend our time and what we do to take care of ourselves.
