10 things about sleep you should know

How do you normally sleep? Do you enjoy a deep and curative sleep? Or are you perhaps one of those people who wake up often during the night? Without a doubt, insomnia is the worst affliction that we can suffer from at night. And another aspect is, if it becomes chronic it can lead to quite serious health problems.

Today in our blog we want to invite you to discover 10 fascinating aspects about sleep that you will certainly find interesting. And remember, a continual lack of sleep is something that we must treat in a proper way.

Never limit yourself to exclusively using the classic sleeping pills or benzodiazepines since sometimes a simple change in our daily habits or diet can give us excellent results.

1. Lack of sleep can cause weight gain

A recent study published in the magazine Endocrine Society revealed something that we should keep in mind. If we suffer from chronic insomnia or we don’t achieve a curative sleep at night, our metabolism slows down and the functioning of our lymphatic system is altered.

Our body stops adequately filtering out toxins, the liver cannot effectively purify itself and this causes us to gain weight little by little. However, the simple habit of going to bed at the same time each night and of resting adequately for at least 6 to 8 hours, is a wonderful gift we can give our health in general. And this will also help us lose weight!

2. How many hours should we sleep each night?

In general this depends on each person. There are some people who need to sleep for 9 hours in order to feel clear headed in the morning; on the other hand, some people only need 6 hours. However, it is important that you keep these points in mind:

  • You should never sleep less than 6 hours.
  • The ideal for sufficient rest is to enjoy at least 5 uninterrupted hours of sleep.
  • If you are an adult, it is not recommended that you sleep more than 11 hours at once (unless you need to recoup many hours of sleep that you previously lost). If you sleep more than 11 hours you may feel the opposite effect, that is, you may wake up tired.

3.  Sleeping too little can cause loss of bone mass

A work published in the magazine Journal of Bone and Mineral Research Review, informs us about a very important aspect that you should be aware of:




  • Sleeping too little and suffering from sleep apnea has been linked to osteoporosis.  Why? Sleep apnea causes our body to receive less oxygen, causes inflammation and as a consequence, changes our metabolism. All of this affects our bone mass.

4. Sleeping too little can cause dementia

In this case, we must also add sleep apnea to insomnia which can cause this worrisome risk to appear. The continual lack of oxygen night after night directly affects our brain health, produces small mini-strokes which, sooner or later, result in dementia. This is something very dangerous.

Remember that it is vital that you consult with your doctor if you suffer from sleep apnea.

5. What if we do a little exercise?

Something so simple like going for a walk for 15 minutes after dinner will help you not only to achieve a good sleep but also to sleep for additional hours straight. Therefore, do not hesitate to do a little exercise each day. It’s worth it!

6. The benefits of a small nap

Who said that a nap is only for bums? Not at all! Sleeping in the middle of the day for 15 to 20 minutes will help you to recoup the sleep you lost during the night and, at the same time, it will relax you and help you be calmer at the end of the day.

7. The benefits of yoga or meditation

According to what the experts say, those who usually suffer from higher levels of insomnia are those people aged 50 years or older. Doing some type of relaxing exercise each day is very positive for everyone but in the case of older ones the benefits are even greater.

If you are motivated to try yoga, for example, you will discover how you can achieve a much deeper sleep, and further improve other areas of your life.

8. Insomnia overstimulates our brain

The brain needs our body to rest during the night because this is the time when it can perform its own functions such as organizing information, sending orders to the lymphatic system to detox the body, storing memories, dreaming …

Now then, if you stay awake and your brain overstimulates, you will suffer from headaches, tiredness in the morning, lack of concentration …

9. Insomnia makes us lose “a little” bit of our memory

Just as we have indicated before, the brain needs a good night sleep in order to organize information, to sort and log data and memories. If this does not happen, if you have a sleepless night, the brain cannot perform any of these functions. Little by little, you will begin to note that it is more difficult to remember information, such as forgetting appointments, conversations, dates … Sleeping is so important!!

10. During the night we experience a real “brainwashing”

Surprised? It is just an expression for a very curious function:

  • During the night, our brain cells shrink so that the cerebrospinal fluid can pass more freely. The job of this liquid is to carry away all the waste products which the cells have produced during the day. As you can see, this is something very important and if we do not sleep properly this function cannot be performed and we will suffer from an accumulation of toxins.
