Is 4 Hours of Sleep Enough?
Many people say that they sleep very little. Even Shahrukh Khan. But is 3-4 hours of sleep enough for a healthy lifestyle? SleepGuru explores.
Sleep affects productivity, health, creativity, beauty, and weight. Every aspect of your mind, body, and health are directly in tune with the quality and quantity of sleep.
The benefits of sleep are too numerous and significant to be ignored. So how much sleep do you really require? This article will explore that question.
Minimum Sleep Required
Research cannot predict the exact number of hours required by a body but it gives you a general rule of thumb. The prominent deciding factors are:
On average, about one-third of your entire lives is spent sleeping. As per the National Sleep Foundation, this translates to about 8 to 9 hours of sleep for an adult. Other factors that play an important role include:
- Sleep quality and pattern
- External factors like noise, mattress and eating pattern
The Sleep Cycle
As per Sleep Council, the sleep cycle is divided into:
- Non-rapid eye movement (NREM)
- Rapid eye movement (REM)
You initially enter the NREM stage which progressively deepens into NREM 1, 2 and 3. Thereafter it’s the REM stage where you dream. To be fully rested you need to experience all the 4 stages of sleep.
The Debate on Quality and Quantity
Sleep quantity refers to the number of sleep hours and quality is how well you actually slept. Sleep Foundation defines good sleep quality as:
- Falling asleep within 30 minutes of shutting eyes.
- Continue sleeping throughout the night.
- Drift back to sleep within 20 minutes in case you do wake up.
Poor quality sleep involves:
- Trouble falling asleep
- Frequent waking at nights
- Early awakenings.
Even 6 hours of quality sleep is better than 9 to 10 hours of bad sleep. It’s both quantity and quality that you want to aim for.
There are so many myths and facts about sleep. You can easily get confused with all that information. Below are some real facts to help you:
- Even one hour of sleep loss will eventually add up
