How much do you need to sleep every day?

Sleep is not a luxury, in fact, it is a necessity. All of us have different sleeping patterns and habits and how much you should sleep? It cannot be generalised. Ideally, eight hours of quality sleep every night is recommended by experts.


Since no two individuals have the same habits, lifestyle, eating habits etc. You are the best judge to figure out how much sleep is enough for you. A general rule to know if you are getting good, quality sleep every night, see how you feel in the morning. If you wake up tired, lazy, grumpy and a heavy head, most likely you did not get quality sleep. Study your sleeping patterns for a week or so and tweak it accordingly.

You are sleep deprived if:

  • You need an alarm to wake-up
  • Use snooze button
  • Cannot pull yourself out of bed, laze around
  • Become sluggish as the day passes
  • Yawn in meetings, lectures etc.
  • Get drowsy after eating or while driving
  • Always craving for a nap to get through the day
  • Fall asleep watching TV, relaxing in the evening
  • Sleep in most of the weekend
  • Doze off within 5 minutes of hitting bed

If you think you are sleep deprived, the only way to compensate is by getting more sleep!

You might be sleep deprived for a long period of time and might not even have realised. Look back and analyse past few months of your life. Chances are you would have a fairly good sleep deficit. You might need weeks even moths to recover.

First and foremost, cut back on caffeine and energy drinks. They might seem to be helping you boost energy and concentration, they are doing more harm to your sleep and disturbing your sleep patterns and keeping you awake longer than you need to be.

Try and go to bed little early, turn off your gadgets and phones. Don’t bother yourself about facebook updates and checking what your friends are up to. Remind yourself that you need to catch up on all the sleep you have missed on for good.

Health Hazards of Sleep Deprivation You Should Know


5 Major Health Hazards Of Not Getting Enough Sleep

Lack of Sleep Raises Your Risk of Type 2 Diabetes

There are a number of studies which suggest the lack of sleep play a significant role in insulin resistance leading to type 2 diabetes.

Another research showed women who slept five hours or less every night were 34 percent more likely to develop diabetes symptoms than women who slept for seven or eight hours each night.

According to research published in the Annals of Internal Medicine, after four nights of sleep deprivation (sleep time was only 4.5 hours per night), study participants’ insulin sensitivity was 16 percent lower, while their fat cells’ insulin sensitivity was 30 percent lower, and rivaled levels seen in those with diabetes or obesity.

According to Mark Mahowald, MD, director of the Minnesota Regional Sleep Disorders Center in Hennepin County, “The body’s reaction to sleep loss can resemble insulin resistance, a precursor to diabetes. Insulin’s job is to help the body use glucose for energy. In insulin resistance, cells fail to use the hormone efficiently, resulting in high blood sugar”.

It Raises Your Risk for Cardiovascular Disease

Studies suggest that a single night of inadequate sleep in people who have existing hypertension can experience elevated blood pressure the next day. Another study found that sleeping less than 6 hours or more than 9 hours, increased the risk of coronary heart disease in women.

Makes You Gain Weight

While we sleep, our bodies secrete hormones that help control appetite, energy metabolism, and glucose processing. So when you are not getting enough sleep, it upsets the hormone balance like increased production of cortisol, often referred to as the stress hormone.

According to a 2004 study, those who sleep less than six hours a day have 30 percent more chances to become obese compared to those who slept 7 to 9 hours. Sleep is now being seen as a potential risk factor for obesity along with the lack of exercise and overeating.

Lack of Sleep Kills Sex Drive

Sleep experts say that people who are sleep-deprived report lower libidos and less interest in sex which is related to low energy levels, sleepiness, and increased stress.

Poor sleep lowers testosterone levels significantly which leads to lack of sex drive in men. Sleep deprivation can also leave a long lasting impact on hormone levels.

A study, published this month in Journal of the American Medical Association (JAMA) states that getting less than 5 hours a sleep ever day for a week reduces testosterone levels drastically and more akin to someone who is 15 years older.

 Lack of Sleep Damages Your Skin

Chronic sleep loss can have a drastic effect on your skin. It could give you dark circles, wrinkles, dull skin which could make you look much older than you are.

Being sleep deprived increases the release of the stress hormone cortisol which breaks down skin collagen. Collagen is what gives you that smooth and elastic skin

When you don’t get enough sleep, your body releases more of the stress hormone cortisol. In excess amounts, cortisol can break down skin collagen, the protein that keeps skin smooth and elastic.

To conclude:

If you are among those who sleeps for six hours or less and think that is enough for you, chances are you are fooling yourself. Maybe you have adapted to live with less sleep. You might have your own reasons or obligations, getting proper sleep will add to your overall health and make you feel more energised, vibrant and happy.
