How does sleepless affect our health and weight control?

It has been shown that not sleeping enough hours is related to a decrease in concentration, in addition to irritability, tiredness and even an increased risk of suffering from psychiatric illnesses . Also, if you have set out to lose weight, this lack of sleep may make it difficult for you to reach your goal. Resurge Review

The act of sleeping is very important so that our body can carry out many of its main functions. In an adult it is recommended to sleep between 7 and 9 hours a day, but it can vary according to each individual. We can find people who with 6 hours have more than enough and others who need 10.

What happens when we don't get enough sleep?

We are used to very long working days, leaving very little time for leisure activities, which is why many of us sacrifice adequate rest to prioritize these activities.

Increased appetite

When we deprive our body of a correct rest, several hormonal alterations occur (especially Leptin and Ghrelin, they are hormones in charge of regulating hunger). Ghrelin stimulates appetite, while Leptin is responsible for reducing it. When we do not get enough rest, Leptin levels decrease, while Ghrelin levels increase, making those people who do not get enough rest more likely (in the long term) to be overweight or obese, as they will end up making more abundant intakes. In other words, an increase in fat mass is produced due to an increase in appetite.


It has been shown that when we don't get enough sleep we increase our food intake to try to supply the energy we lack, just as we increase our consumption of coffee and energy drinks. It is important to remember that a higher caffeine intake than recommended can have harmful effects on our body and cause insomnia, nervous states, anxiety and even gastrointestinal discomfort.

Also, this tiredness will make it difficult for you to make the right decisions when choosing the right food. It is important that you plan, that you have healthy food prepared both in the fridge and in the freezer and that you make a good purchase, so you will not give option to make bad choices. Of course, you should not abuse energy drinks, because as we have just commented, they can be counterproductive when it comes to providing us with a good rest.

Difficulty losing body fat

Cortisol is also known as the stress hormone. With sleep restriction, blood levels of Cortisol are increased, a consequence that makes it difficult to lose body fat. I recommend that you encourage relaxing activities to decrease stress levels and consequently reduce the amount of Cortisol in the blood.

If you are trying to lose weight, it is advisable to pay close attention to your sleep routine, without neglecting your eating habits, physical exercise and stress control .

It has been seen that people who suffer from both excess and underweight have a higher risk of insomnia, which means that it is very important to take care of your eating habits. It is important to follow a balanced diet, to stay at a healthy weight and maintain proper sleep hygiene. Furthermore, excess weight is directly related to the risk of suffering from sleep apne .
