How Sleep Affects Health


Sleep is an important part of our daily lives, one which many take for granted. For those that are aware of the significance of a good night’s sleep, they often relate a grumpy mood and the lack of work drive as an unhealthy sign of the lack of sleep.

However, it goes well beyond this.

There are psychological effects of inadequate amounts of sleep that could put you at a risk of developing serious health issues including heart disease, diabetes and obesity.

Which then takes us to the next question…

Just how much sleep is healthy?

The average human being needs at least 8 hours of sleep. However, this is not a strict rule and some people may actually need more than this depending on lifestyle and general health. Some, on the other hand, is perfectly fine with around 6 or 7 hours of sleep a day.

Find out which is best for you. If after 8 hours of sleep you stiff feel lazy and unable to work properly, then you might need to increase the number of hours you spend between the sheets.

Let’s find out how sleep improves your overall well being

  1.    Better immunity

A lack of sleep will disrupt your body’s immune system. If you notice that you get sick easily and seem to catch a cold with every slight drop in temperature, then there is a chance that your sleeping is to blame.

  1.    Healthy mental state

We know that a lack of sleep can make you irritable and grumpy. What we may not know is that there is a correlation between a lack of sufficient sleep and mental disorders such as depression and anxiety.

Think about it for a sec! If you lack sleep for continuous nights and you remain grumpy for most days of the week, then anxiety and depression will not be too far behind.

  1.    Fighting diabetes

Sleeping fewer hours has been shown to affect how the body processes glucose. This puts you at a high risk of developing type 2 diabetes. In fact, studies have shown a correlation between diabetes and a lack of sleep, especially when getting less than 5 hours a day.

  1.    Sex drive

The lack of sufficient sleep affects the sex drive of both men and women with both showing less interest in sex. In fact, certain ailments such as sleep apnea lowers the levels of testosterone in men resulting in a lower sex drive.

  1.    Heart disease

There are studies that have shown an increase in heart rate due to inadequate sleep. Moreover, there is an increase in blood pressure which puts even more pressure on the heart.

How to counter the effects of inadequate sleep

If you feel like you’ve been getting less sufficient sleep, it’s time to hit the bed. Turn off any alarms during the weekends and let the body wake you up in the morning.

Don’t rely too much on caffeinated drinks during the day as these will disrupt your sleeping. During weekdays when you have to get up early for work, go to bed early.

Your body will not recover immediately but over a period of getting good sleep, you will feel different—more rejuvenated during the day.
