People Who Consistently Get Less Than Six Hours of Sleep Have a Higher Risk of Dying Sooner Than People Who Consistently Get Six to Eight Hours of Sleep.

Date: 2023-12-14
For most of us, sleeping less than six hours a night harms more than just the brain. Short sleepers have a fivefold increased risk for stroke, and when combined with other common conditions, such as diabetes or high blood pressure, they can double the risk for heart disease and death.

According to a study, people who sleep less than seven hours per night have a 12% greater risk of dying than those who sleep seven to eight hours per night. Another study found that people who slept less than six hours per night were 2.5 times more likely to die over seven years.

However, a study of over one million people found that those who slept six or seven hours had a lower death rate than those who slept eight or more hours. The study also found that sleep regularity is more important than how long you sleep. 

In the hustle and bustle of modern life, a good night's sleep is often sacrificed for work, socializing, or binge-watching our favourite shows. However, recent research underscores the critical importance of sleep in determining our overall health and longevity. The phrase "People who consistently get less than six hours of sleep have a higher risk of dying sooner than people who consistently get six to eight hours of sleep" is not just a cautionary statement; it's a wake-up call to prioritize our sleep for a longer and healthier life.

The Sleep Connection to Longevity

The human body functions on a delicate balance, and one of the key orchestrators of this balance is the circadian rhythm, an internal clock governing our sleep-wake cycle. Disruptions to this rhythm, such as chronic sleep deprivation, can lead to a host of health issues and potentially shorten our lifespan. 

Understanding the Research

Numerous studies have examined the impact of sleep duration on mortality rates, consistently revealing a clear association between inadequate sleep and an increased risk of premature death. Individuals consistently receiving less than six hours of sleep are more susceptible to a range of health issues, including cardiovascular diseases, diabetes, obesity, and compromised immune function. These conditions, in turn, contribute to a reduced life expectancy.

The Six to Eight-Hour Goldilocks Zone

Experts often tout the ideal sleep duration as falling within the six to eight-hour range for adults. This range is considered the Goldilocks zone, where the body has ample time to progress through the essential sleep cycles, from light to deep sleep and REM (Rapid Eye Movement) sleep. This balanced sleep duration is associated with better cognitive function, emotional well-being, and overall physical health.

Strategies for Addressing Your Sleep Deficit

Recognizing the importance of sleep is the first step towards a healthier and potentially longer life. Here are some strategies to address the sleep deficit:

Prioritize Sleep: Make sleep a non-negotiable part of your daily routine, allocating sufficient time for quality rest.

Establish a Sleep Routine: Create a consistent pre-sleep routine to signal to your body that it's time to wind down. This may include activities like reading, dimming lights, or practising relaxation techniques.

Optimize Sleep Environment: Ensure your sleep environment is conducive to rest—a comfortable mattress, cool room temperature, and minimal noise and light.


It is impossible to overestimate the profound relationship between sleep and longevity. We must prioritize our well-being by first acknowledging the risks that come with regularly sleeping for less than six hours each night. It is critical to realize that getting enough sleep is essential for leading a healthy, fulfilling life, even in a culture that frequently celebrates hard work and sacrifices leisure for productivity. 

So, let's collectively reevaluate our priorities, embrace the sanctity of sleep, and pave the way for a healthier, more extended journey through life. After all, a well-rested life is a life well-lived.
