Sleep is a very important aspect of our life as it affects not only our mood and energy levels but also our physical state and mental abilities. However, not all of us have the time to get some restful sleep which leaves us feeling tired and disoriented in the morning. Knowing the science of sleep cycles may enable you to master your sleeping patterns. Complement this understanding with science of napping for energy and focus to optimize your daily performance. This blog post will dwell into the details of the sleep cycles, the mechanics of sleep, and the ways in which you can maximize your sleep to have a fresh wake-up experience.
Understanding Sleep Cycles
Sleep is not an objective condition but a complicated process which consists of a number of stages which occur in cycles all night. It is estimated that each of these cycles takes approximately 90 minutes and has both non-REM (rapid eye movement) and REM sleep.
The Stages of Sleep
Stage 1 (NREM 1): It is the lightest phase of sleep taking only a few minutes. It acts as the linking between the state of waking and sleep. At this age, your heart rate will reduce and your muscles will relax. You can have a short-lived contraction of the muscles or feel like falling.
Stage 2 (NREM 2): At the stage your body gets deeper into a stable sleep. The rate of your heartbeat slows down, and your body temperature decreases. Sleep spindles and K-complexes take place and these are the waves that are present in the brain and are found to aid in the protection of sleep and also in consolidation of memories.
Stage 3 (NREM 3): This stage is also referred to as deep sleep or slow-wave sleep, which is the stage that is important in physical renewal. NREM 3 repairs tissues, builds bone and muscle and boosts the immune system. It is because you are still non responsive to external stimuli in this stage, and thus hard to wake up.
REM Sleep: This is the stage when the brain is the most active and the eye moves fast like in the time we are awake. The cognitive processes like memory consolidation, learning, and processing emotions are impossible without the help of REM sleep. The major portion of dreaming is done during this stage.
During a normal night, you will repeat these stages severally with the level of the REM sleep being higher towards the end of the night. These cycles are important to understand in order to maximize your sleep.
The significance of Sleep Cycles
The science of sleep cycles tells you that it is not the amount of sleep that matters as much but the quality. When you wake up when you are asleep deeply, you will feel groggy and disoriented and this is called the sleep inertia. That is why setting your alarm clock to wake up at the end of a sleeping wave, especially in a light sleep such as the NREM 2 or REM can greatly influence how well you feel upon getting up.
The Exposure to Risk of Sleep Disruption
The problems that can be caused by interruptions on your sleep cycles include:
Heightened fatigue: Stolen sleep is stressful as it causes lack of REM and deep sleep causing daytime drowsiness.
Problem in thinking: Problems in memory, decision-making, and solving problems are caused by the absence of restorative sleep.
Mood disturbances: Sleep deprivation may cause irritability, anxiety and depression.
Physical health problems: Obesity is associated with chronic sleep disruption; diabetes, cardiovascular disease, and a compromised immune system.
By learning the art of sleeping cycles, one can reduce these dangers and improve on his or her overall well being.
How to maximize your sleep cycles

It may be necessary to use black out curtains, ear plugs or even white noise machines. The optimum room temperature to sleep is 60 to 67 degrees Fahrenheit (15 to 19 degrees Celsius).
4. Restrict alcohol and caffeine intake
Caffeine, alcohol can drastically interfere with your sleeping pattern. Caffeine should not be consumed in the afternoon or evening because it can be retained in your body hours and will not allow you to sleep. Though alcohol can also enable you to fall asleep much quicker, it can disrupt REM sleep resulting in interrupted sleep later at night.
5. Include Physical Exercise
Exercise also leads to improved sleep patterns, as it makes you fall asleep quicker and have a more satisfactory sleep. Goal of at least 150 minutes of moderate aerobic exercise a week. Nevertheless, complete exercise should be done as much as possible before going to sleep because it will cause alertness and cause more difficulty when falling asleep.

8. Be Mindful of Your Diet
