Do we really need an 8 hour sleep?

12 January, 2017

We’re sick and tired of people saying that sleeping for 8 hours automatically means we had a good and quality rest but, is eight the magic number when it comes to sleeping hours? Today we review all the information on the matter so we can answer the question, “How many hours do I need to sleep so my body doesn’t want any more or less?

Do we need to sleep for 8 hours?

Most adults need to sleep for 7 to 8 hours, with a preference for a routine schedule. If you work shifts, you should adapt yours so your sleep hours are as uniform as possible. Sleep quality is way more important than the number of hours we sleep as it’s what really matters when it comes to achieving that snoozing effect that keeps the body rested.

Every person is different and there’s not a golden rule that apply to everyone. However, there seems to be a consensus on a 7 to 9 hour sleep to be the best thing for our body. If you’re tired during the day, use the weekend to get some sleep hours back. If even doing this you want to smash the alarm clock, you might have a lack of sleep that needs to be treated.

How much to sleep, agebased

As we get older, our body and mind need less sleep time to be active. If you want to check how much do we usually sleep depending on our age, you can check one of our old g!sleep posts.

You’ve surelly heard your parents and grandparents saying they don’t sleep that much anymore or they wake up very early in the morning. This is completely normal as their body needs less sleeping hours.

Does everyone need the same sleep?

In order to avoid a lack of quality sleep, we should be careful of sleeping enough so… how much is enough? It’s as easy as listening to your body learning to understand what it is asking for. Humans are made to feel sleepy when there’s no light, which is around 7 or 8 hours, and what most people feel good about. However, some particular cases may need more and 8 hours can feel like a total nightmare in the morning. On the other hand, there’s people that are as fresh as a daisy with less than 7 hours of sleep and sleeping more than that is completely pointless for them. Find what’s right for you and you’ll feel the difference. Healthier people fall asleep easily at night and wake up without the help of an alarm clock. You can try during the holidays and you’ll see how much does your body need. This way you can get to know the right amount of time for you! Some smartwatches such as Geeksme’s GME1 allow you to monitor your sleep so you don’t need to write down your information.

Never sleep less than 6 hours

Although there are some exceptions, sleeping less than 6 hours will usually make us feel bad. Some authors say that sleeping less than 6 hours is as bad as sleeping nothing at all, as both body and mind are so tired they can’t work properly.

Consequences of sleep loss

Not sleeping enough has serious consequences that affects humans both physically and psychologically. Besides being tired, sleepy, clumsy and having dark circles, we can be grumpy and suffer of memory loss in the long run. Sleeping less than we need causes recurring head aches and hallucinations and increases the risk of suffering a heart attack. Hormonal changes induced by sleep loss lead to lack of apetite and being more likely to suffer obessity. A proper sleep keeps us healthy and the opposite will decrease our life quality.
