Rest is crucial for both your physical and mental well-being. It stands as a fundamental necessity in our existence. A good night’s rest revitalizes you, whereas a deficit in sleep can significantly affect you. However, determining the ideal duration of sleep can be perplexing. This article will assist you in understanding whether four hours of sleep is sufficient for you.
Is 4 Hours Sleep Enough?
A recent extensive sleep study conducted by scholars at the University of Western Ontario, involving 40,000 participants, revealed that individuals who slept between seven and eight hours per night exhibited superior cognitive performance compared to those who slept either more or less. This study was also featured by the Sleep Research Society.
The research further indicates that insufficient sleep significantly impairs cognitive function. According to recent analysis by Healthline, sleep deprivation can lead to substantial physiological changes that heighten the risk of serious health issues such as obesity, diseases, and even premature mortality. The findings also suggest that excessive sleep could be equally detrimental to health. Nevertheless, the research clarifies that sleeping four hours per night does not fall under severe sleep deprivation.
What about just 4 hours of sleep? Neuroscientist Dr. Ying-Hui Fu believes it is possible to manage with only four hours of sleep nightly. Dr. Fu discovered in her research that individuals who felt perfectly rested after only four hours had all inherited a variant of the DEC2 gene.
How Much Sleep Do You Need?
The amount of sleep required is influenced by factors such as age, lifestyle, diet, and daily activities, and varies among individuals. While some are comfortable with just 4 or 5 hours of sleep, others may experience sleep deprivation after sleeping more than this. Various studies have attempted to determine the optimal sleep duration, although there remains debate among researchers.
We have provided a table below from the National Sleep Foundation that delineates the average recommended sleep duration for various age groups:
| Age | Hours Needed | May Be Appropriate |
