Why is Sleep So Important?

Sleep is an essential component of our physical and mental health that allows our bodies to rest and recharge. A healthy sleep schedule can be challenging while juggling the responsibilities and pressures that accumulate throughout the day. Nonetheless, it is critical to prioritize how and when you sleep in order to improve the quality and productivity of the day.

Why is Sleep So Important?

Poor sleep can be both a consequence and cause of poor mental health. Moreover, maintaining unhealthy sleep schedules can often lead to the development of mental health disorders such as anxiety or depression. Conversely, an individual already struggling with a mental health disorder can develop sleep disorder, exacerbating the preexisting disorder.  

While ongoing research continues to understand the effect of sleep on our mental health, evidence indicates that mental health disorders can have negative consequences on sleep health. It is estimated that 90% of youth who struggle with depression experience sleep problems. It is important to prioritize your sleep and maintain healthy sleep habits, particularly when coping with physical or mental health challenges.

Sleep cycles are divided into four stages. The first three stages are known as non-rapid eye movement (NREM) sleep, and the final stage is known as rapid eye movement (REM) sleep. During the first and fastest stage of NREM sleep, the body transitions from being awake to being asleep as muscles relax, breathing slows and heart rate decreases. The second stage of NREM sleep is the longest–muscles become even more relaxed, body temperature decreases and eye movement stops. The third stage of NREM sleep is when the body reaches its most relaxed state, comprising the most important stage of feeling refreshed the next day. The final stage of sleep is known as REM sleep where blood rate, heart rate and breathing will begin to increase. Dreaming typically occurs during this stage.

The four stages of sleep, lasting for approximately 90-120 minutes, cycle throughout the night. Sleep cycles and their duration can vary from person to person and there are many studies that dive deeper into the specifics of each cycle.

The amount of sleep each person needs can vary based on multiple factors. A primary indicator of how much sleep a person needs is their age. Younger individuals tend to require more sleep than sleep adults.

According to the CDC, the below table outlines the appropriate amount of sleep needed for each age group.
