5 Hours vs 8 Hours Sleep: How Much Sleep Do We Need?

Manoj Prasad

In today’s busy world, many people think that resting and sleeping are useless activities and instead choose to work, hang out with friends, or watch TV.

However, this view is very different from the truth. Sleep is an important part of your physical, social, and emotional health, not just a time to do nothing. Without it, the mind and body have a hard time working right.

Let’s talk about why sleep is important, what happens when we don’t get enough, and why most people today might not be able to follow the sleep habits of old yogis and sages.

Why Sleep is Essential for Our Body and Mind

Sleep is an important part of keeping the body healthy and healing it. Here are some of the most important ways it improves our health:

1. Repair and Rejuvenate the Body

Several healing processes happen in the body while we sleep. Tissues are fixed and cells grow back, which is especially important for muscles that have been worked out or hurt. People who live busy lives can naturally repair themselves while they sleep. (Source)

2. Strengthen the Immune System

Getting enough sleep makes the immune system stronger, which helps the body fight off sickness and infections. When people don’t get enough rest, their immune systems weaken, making them more likely to get colds, flu, and other illnesses. (Source)

3. Support Heart Health

Sleep is a very important part of keeping your heart healthy. It keeps blood pressure in check and lowers stress factors, which can put stress on the heart. Lack of sleep over a long period of time has been linked to higher risks of heart disease, stroke, and other heart problems. (Source)

4. Clear Toxins from the Brain

During deep sleep, the brain gets rid of the dangerous chemicals that build up during the day. This process of cleansing helps the brain work better, remember things, and think more clearly. When people wake up after a good night’s sleep, they often have more clarity and can solve problems better. (Source)

5. Regulate Mood and Stress Levels

There is a strong link between sleep and happiness. Not getting enough sleep can make us irritable, anxious, or easily stressed. On the other hand, getting enough regular quality sleep makes us more emotionally strong and better able to handle stress. (Source)

The 5-Hour Sleep Experiment: A Wake-Up Call

To understand what happens when you don’t get enough sleep, look at the results of a study where people could only sleep five hours a night. The results were scary:

  • Reduced Concentration: Participants experienced significant difficulty focusing, highlighting how essential sleep is for cognitive functions like attention and decision-making.
  • Increased Stress Levels: The lack of rest heightened their stress, making it harder for them to manage emotions and remain calm in challenging situations.
  • Weakened Immune Response: Sleep-deprived individuals showed a reduced ability to fight off infections, underscoring the link between sleep and immunity.
  • Higher Blood Pressure: Sleep deprivation led to spikes in blood pressure, which, if sustained, could increase the risk of chronic heart conditions.

This experiment makes it clear that five hours of sleep is not enough for most people to stay healthy. Adults should get between 7 and 8 hours of sleep each night. This gives their bodies and minds the time they need to rest and get ready for the next day.

Why It’s Not a Good Idea to Compare Ourselves to Ancient Yogi’s

People often romanticize stories about old sages and yogis who did well with little sleep. Like, it is said that Buddha only slept for an hour every night for 45 years.

Even though they are interesting, these stories are about people whose lives were shaped by unusual spiritual practices, not by the facts of modern life.

The Yogic Lifestyle

The lives of yogis were very different from those of most people today. They spent their days meditating, fasting, and practicing spiritual discipline, which changed what their bodies and minds needed.

Their biology was largely changed by their sadhana (spiritual practice) and tapasya (austerity), which allowed them to perform with little sleep.

Modern Life’s Challenges

In contrast, today’s fast-paced lifestyle is characterized by:

  • Mental Overload: The constant barrage of information, social media, and multitasking creates mental clutter, making deep rest even more necessary.
  • Dietary Habits: Modern diets often include processed foods, sugar, and caffeine, which disrupt sleep patterns and overall health.
  • Stressful Routines: Work pressures, family responsibilities, and societal expectations leave little room for relaxation or mindfulness.

Unlike yogis, who were in a constant meditative state, most people today lack the mental and emotional discipline to achieve such balance. Therefore, trying to emulate their sleep patterns is neither practical nor healthy.

The Role of 7 to 8 Hours of Sleep in Modern Life

7 to 8 hours of sleep is not a privilege for most people; they need it. This time frame gives the body and mind time to process the day’s events, feelings, and obstacles. This is why it’s important:

Processing Emotions: The brain processes emotional events while we sleep, which helps us wake up with a clearer view of things and better control our moods.

Enhancing Productivity: People who get enough rest are more productive, creative, and able to solve problems.

Improving Physical Health: Sleep is good for your health in many ways, from reducing inflammation to controlling hunger hormones.

Promoting Longevity: Studies show over and over that people who get enough sleep are more likely to live longer and better lives.

Tips for Better Sleep in a Busy World

Create a Sleep-Friendly Environment: To get a good night’s sleep, keep your bedroom cool, dark, and quiet. If you need to, you could use blackout shades, white noise machines, or eye masks.

Stick to a Schedule: No matter what day it is, go to bed and wake up at the same time. This stability helps keep your body’s clock in sync.

Limit Screen Time Before Bed: Melatonin is a hormone that controls sleep. Blue light from computers can stop your body from making it. Stay away from electronics at least an hour before bed.

Practice Relaxation Techniques: Deep breathing, yoga, and meditation can all help calm the mind and get the body ready for sleep.

Be Mindful of Diet: Heavy meals, coffee, and alcohol should be avoided right before bed because they can make it hard to sleep.

The Sacredness of Sleep: A Modern Perspective

A holy act of healing and restoration, sleep is a gift that gives us the energy to start each day fresh.

Though stories about yogis and elders are interesting, it’s important to keep in mind that their lives were very different from ours.

They were at peace with nature and didn’t have to deal with the worries and distractions of modern life.

Most of us can’t live without sleep. It is the base on which good mental health, physical health, and social health are built. The more sleep we get, the better care we give our bodies and minds, so they can grow and thrive.

Don’t think of sleep as a waste of time; instead, see it as one of the best ways to heal. The simple phrase “sleep well, live well” can change your life for the better.
