If you could make one small change today, what would it be?
Go to bed earlier and sleep longer – this is what research proposes.
Sleep is one of the few universal behaviors among mammals and birds, which suggests that it performs an important function. Although it feels necessary to recover from moving and exercising our bodies, studies show that sleep deprivation does not damage the body. On the other hand, it appears that sleep is essential for normal brain functioning, and mental exercise increases the demand for deep sleep.
The stages of sleep tend to follow an orderly sequence:
Sleep deprivation studies show numerous negative consequences not only to performance (fatigue, poor decision-making abilities, lack of energy) and memory (difficulty concentrating, forgetfulness, trouble remembering), but also to overall health – physical (weight gain, high blood pressure, compromised immune system) and mental (irritability, mood swings, symptoms of anxiety and depression).
Sleep has such a broad and significant influence because during the restoration stages there is a release of a number of hormones, regulating various systems in our bodies, such as ghrelin and leptin (regulating hunger/body weight), cortisol (involved in metabolism, stress and immune response), growth hormone (essential for tissue repair), oxytocin (aka “love hormone” involved in social behavior).
Additionally, both serotonin and dopamine – two essential neurotransmitters for our mental health and digestion (along the Gut-Brain Axis which I wrote about here – link to previous article?) – are also involved in the sleep cycle. Last but not least, during sleep the sympathetic nervous system, which is responsible for the flight-or-flight response gets a rest, and so do we – from various stressors or anxious thoughts we might have on our minds.
