Sleep is essential for human beings as it is the time when the body undergoes repair and restoration. It is also when the brain sorts and archives the information that has been processed throughout the day. Yet, despite its importance, research has found that almost a third of adults get less than the recommended seven hours of sleep each night.
So, what’s the science behind sleep? There are two types of sleep: rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep. During REM sleep, the brain is active and eyes move rapidly while the body is paralyzed to prevent acting out dreams. In NREM sleep, the brain is less active, and the body repairs and restores itself.
Further studies reveal the impact sleep has on our health. Inadequate sleep has been linked to a range of health complications, including obesity, cardiovascular disease, diabetes, and depression. It also impairs cognitive function, alters mood, and can damage the immune system. Thus, improving sleep quality can have a positive impact on our overall health and well-being.
But what can we do to get better sleep? First, we need to establish a regular sleep routine and stick to it. This includes going to bed and waking up at the same time each day, even on weekends. We should also ensure our sleep environment is conducive to rest. This means investing in a comfortable mattress and pillow, reducing outside noise and light, and maintaining a cool temperature.
Additionally, consuming less caffeine and alcohol before bed, avoiding large meals, and minimizing electronic device use can also help us drift into a restful state. Lastly, if sleep deprivation persists, it may be wise to seek advice from a medical professional or learn effective sleep hygiene techniques to help us sleep soundly and achieve a healthy body and mind.
