Sleep is not a luxury. It is one of the biological necessities like food, water, and oxygen. However millions of individuals, particularly in the hectic way of life in India, routinely get less than 6 hours of sleep every night – without considering the covert harm it is inflicting on their physique and mind.
Whether it is young students who are studying to pass competitive tests or people in the IT sector who have to work late at night and home makers who are able to afford to sleep all night, sleep deprivation has become an unspoken issue in India. The worst part of the problem is that most people consider poor sleep as normal.
Sleep deprivation is not a normal condition. It is not harmless. And nor does it get better of its own.
Getting less than 6 hrs of sleep will always have a ripple effect in your body – it will impact your hormones, metabolic rate, memory, mood, immunity, productivity and overall health. This is a detailed article that dissects precisely what is going on to your body, why Indians are becoming sleepy, and what you can do to take practical steps to undo the damage.
Get down to it–into what exactly goes on with you when sleep comes to the back burner and you only live in simple clear human terms–let’s explore.
The Science Lesson: Why Less Than 6 Hours of Sleep is Dangerous
The circadian rhythm is a biological clock running on your body. This in house system governs:
- Hormone release
- Body temperature
- Appetite and digestion
- Energy levels
- Emotional balance
- Immune response
- Cognitive functioning
This system is interrupted when you do not sleep enough, which is below 6 hours. This is followed by a domino effect that gradually affects almost all of the organs.
Experts on sleep all over the world conclude:
Adults require 7-9 hours of sleep per day to be properly functioning.
Anything below 6 hours the body is on a command of stress, though your body may say it is fine. Indians can boast of many,I am able to work well with 4-5 hours of sleep.
But science claims otherwise.
Your flesh is aching– though you do not see that at the first instant.
Your Brain Smarts You Slower than you Think.
And when you are sleeping less than 6 hours:
Memory weakens
Your brain finds it hard to remember and memorize something. This is the reason why so many students study at night and end up forgetting what they read.
Focus reduces
Minor chores are more fatigued. You read that same sentence numerous times. You have problems concentrating during meetings.
The decision making is impaired
Judging part of the brain gets inactive resulting into impulsive or emotional judgment.
Reaction time drops
This is the reason why driving without sleep is like driving under the influence.
Creativity declines
Your brain is irrelevant in that it is trapped in the mode of survival – there is no place to be creative, solve problems or innovate.
Indian Example
Rohan, who is 27 and works as an engineer in Bengaluru, used to sleep late at 3 AM, having completed late-night work with clients of MNCs. He became asymptomatic in the mornings–but gradually began to forget things, commit coding errors, and experience attention deficits. He has increased his productivity up to twice after switching to a strict 7-hour sleep.
Such are the effects, subtle as they are, but mighty.
Stressing Hormone Shoots Through You
Having less than 6 hours of sleep raises the cortisol or the stress hormone.
High cortisol leads to:
- Anxiety
- Irritability
- Mood swings
- Increased blood pressure
- Accumulation of fats around the stomach.
- Faster aging of skin
- Higher sugar cravings
This is why when you have slept shortly you feel:
- More emotional
- Easily triggered
- More hungry
- Less patient
- Your body is not only tired but it is stressed.
It Depowers Your Immunity in Days
When you don’t sleep enough:
- The quantity of immune cells decreases.
- In your body less antibodies are produced.
- Inflammation increases
This leads to:
- Frequent colds
- Slow healing
- More infections
- Prolonged exposure to the risk of chronic diseases.
Indian Example
In the polluted winter season in Delhi, individuals who sleep poorly take sick leave of absence more often since their body has not been strengthened to resist the combined effects of the environment. Sleep deprivation combined with pollution is deadly.
Harder Than It Should Work Your Heart
Sleep Poors sleep subjects you to the Risk of:
- High blood pressure
- Irregular heartbeat
- Heart attack
- Stroke
The rest of your heart does not come at night. Months and years on this would become a time bomb.
The Indian health surveys indicate that the rate at which hypertension is among urban adults with irregular sleep schedules is considerably greater.
You Gain Fat Without Overeating
A lack of sleep (Less than 6 hours) interferes with the hormones which control hunger:
- Ghrelin (hunger hormone) Increases.
- You are stuffed, but you are so hungry.
- Leptin (saturation hormone) decreases.
What you are eating does not give your body the message to stop.
This leads to:
- Overeating
- Sugar cravings
- Snacking at night
- Slow metabolism
- Belly fat accumulation
This is the reason why even strict dieters do not lose weight when they are sleep deprived.
Your Skin Ages Faster
Sleep deprivation lowers collagen synthesis resulting in:
- Dark circles
- Puffy eyes
- Dull skin
- Fine lines
- Acne flare-ups
Cortisol dissipates collagen – the substance that renders your skin younger.
That is why sleep is the ultimate skincare routine that you can offer to yourself.
Productivity declines by 40 percent
The corporate culture in India fetishises late hours and early mornings.
The causes of sleep deprivation are:
- Slower thinking
- More errors
- Poor coordination
- Low motivation
- Decision fatigue
With a rested mind it will only require 2 hours to complete what a worn out mind requires 5 hours to finish.
Your Hormones are made Imbalanced
There are several hormones under the control of sleep:
- Insulin (blood sugar)
- Cortisol (stress)
- Ghrelin/Leptin (hunger)
- Melatonin (sleep cycle)
- Growth hormone (repair)
- Thyroid hormones
In case these stabilize the following may occur: Symptom exacerbation of PCOS/PCOD.
- Irregular periods
- Low fertility
- Low energy
- Joint pain
- Weight gain
The effects are felt more by women because they are sensitive to hormones.
