6 Ways Sleep Affects Your Overall Health

Posted March 23, 2023

Sleep is an essential part of our daily routine, but it is often one of the first things we put off when we are busy or stressed. However, getting enough sleep is crucial for maintaining good health and wellbeing. In this blog, we will explore how getting enough sleep can affect your overall health and why it is important to prioritize a quality night’s sleep.

According to the Center for Disease Control, adults should be getting at least 7 hours of sleep each night.  Unfortunately, around 1/3 of US adults get less the recommended amount and the prevalence of short sleep duration has remained almost unchanged for the last decade. This is staggering especially when we consider the impact that sleep has on our overall health and wellbeing.

Getting the proper amount of sleep can help support and maintain our immunity, healthy weight, cardiovascular health, cognition, mood and skin.  Here are just a few examples of how sleep can affect these areas. 


Getting the right amount of quality sleep is extremely important for maintaining a healthy immune system. In a study on 153 men and women, they found that those with <7 hours of sleep a night were 3x more likely to develop a cold than those getting enough sleep.3

Healthy weight

Sleep helps our bodies to stay performing their best. This includes maintaining a healthy weight, and also our ability to lose weight (when we want to). During a weight loss intervention trial, researchers found that better subjective sleep quality increased the likelihood of successful weight-loss by 33% as did sleeping >7hours of sleep a night.4

Cardiovascular health

The effects of sleep on heart health have been well studied and are important in understanding public health.  How long you sleep as well as the quality of sleep you get both can have a large impact on our cardiovascular health. The MORGEN Study followed over 20,000 people for 12 years and found that short sleepers and especially those with poor sleep quality had a greater risk of coronary heart disease and cardiovascular disease than those with normal sleep.5


How long you sleep and the quality of sleep you get is directly correlated to improvement in cognitive tests. One example was a study from the World Health Organization on global aging and adult health which showed these exact results.6


There is a direct relationship between how well you sleep and your mood. In a study on 208 individuals, they found that sleep quality was directly responsible for an improvement in mood the next day.7


In a study on 24 women, just 2 consecutive nights of sleep restriction significantly altered skin and facial appearances including a reduction in skin hydration and skin elasticity.8

We learn more and more about sleep as researchers across the globe explore sleep and how it affects us.  With all of these positive effects, it is also important to explore how we can improve our sleep.  Trying to improve sleep is a huge market valued at over $64B in 2021. This includes everything from pillows to sleep masks, all with the promise of helping consumers.  Here at Kemin we are trying to do our small part to improve sleep health by creating natural extracts and proving that they work through clinical studies.
