Can you deny the importance of good sleep?

A few months ago, I was at home after graduating from university. I experienced something different and unwanted or awkward conditions. Most of the time, I would use to feel lousy and clumsy. My brain would remain foggy for most of the day. I was unable to focus and concentrate on things properly. This losing interest and focus on my career were enough to make me even more depressed.

A few months went like that. One day, unexpectedly, I discovered an article stating the importance of good sleep. I gave it a read like many other random articles on my google feed. It was then that I realized to have some sleep issues. I had developed an unhealthy habit of sleeping late at night and then waking up late in the mornings(Perks of being at home).

So, I made some lifestyle changes, focused on my sleep patterns, and managed my bedtime to benefit from healthy sleeping habits to improve my overall health condition.

Here are some of my findings on the importance of good sleep. I’m sure you won’t be able to deny the importance of good sleep after reading the article.

Sleep strengthens the Immune System

Sleep can strengthen or weaken the immune system. Sleep bolsters both innate and adaptive immunity. Research shows that immune functions become active during sleep time. For instance: enhanced production of cytokines. These cytokines perform several immune functions including inflammation to trigger an immune response in case of emergency. The production of cytokines is associated with both the sleep and circadian rhythm(biological clock).
Sleep also improves the vaccine efficacy for adaptive immunity in the body. Therefore, sleep can be used as an indicator to see the effectiveness of vaccines.
