Science shows how much sleep we need at night

How much sleep should we get? What do experts say about that? You will be surprised to learn the scientific verdict on the amount of sleep we should do if we want to enjoy good health and be truly productive.

Many times (and incorrectly) we take sleep hours off to work, study, or train, thinking that we will make more time. But we forget that the benefits we have from a vacation in the right amount are far greater.

1. Helping Fight Depression

Depression is associated with stress hormones such as adrenaline and cortisol. A few hours of sleep increases their production, while if the body relaxes and sleeps well, it facilitates the presence of melanoma and serotonin. These substances oppose negative effects caused by stress and help us to feel better emotionally.

2. Maintain cardiovascular health

Sleeplessness increases the level of blood stress hormones. This, in turn, causes an increase in blood pressure and heart rate. In this sense stress is considered a risk factor in cardiovascular disease.

When we sleep, the brain continues to work because the neural connections do not stop. Some studies have shown that sleep right after study brings improvements in memory.

4. Helping to Lose Weight

Sleeplessness causes the stomach to release more appetite hormone. That's why sleep deprivation is linked to obesity.

5. Contributes to Strengthening the Immmune System

Another of the sleep systems is the immune system because it regenerates and strengthens itself to fight germs and toxins. In other words, if we rest well, we will have a better chance of avoiding infections.

How much sleep should you sleep by science?

As we have seen, sleep affects almost all systems that make the body work. That is why mental, physical, and emotional health depends on the quality of sleep as well as the level of productivity we have.

You probably heard the theory that says we should sleep eight hours a day. This comes from 1938, when Nathan Clayton, a researcher, spent just over a month in a dark cave with one of his students. When they analyzed their sleep pattern, they realized that they slept from 8 to 8 hours a night.

There are several studies supporting that eight - hour sleep brings health benefits. For example, in the case of students, bad sleep has proved to be negatively changing academic performance. The same is true of the workplace.

On the other hand, some studies confirmed that mortality is the lowest among those who sleep 7-8 hours a day and higher for people who sleep less than 4 hours a day. The fact that during the day you perform as expected, sleeping less than 8 hours, does not mean that this is positive for your health.

When we do not get enough sleep, only negative things happen. From health changes to mental and emotional complications. The consequences can be more serious than we think. These are some of the things that happen when we don't get enough sleep.

Increasing risk of Type 2 diabetes causes less insulin relief - the hormone that regulates blood sugar.

Anxieties of anxiety cause stress and, as a result, feelings of anxiety and depression.

Loss of sexual desire can cause low testosterone disorders in men. Poor, poor-quality rest contributes to a reduction in lipids and low sperm production.

It reduces muscle growth that happens especially after the age of 30.

So now that we have information, we know that an extra hour of sleep can be very useful to our health, employment, and all the activities we engage in.

Adults need 8 hours of sleep and babies 13, and teenagers 9. If we multiply these hours for the rest of our lives, we'll find out that we've spent a lot of our lives sleeping.

The question is, is it worth investing all this time in your sleep in exchange for a healthier life? Or will we continue to take time to get some sleep until the body is too late?
