Sleeping well is essential for health. It's even just as important as eating healthy and exercising. Unfortunately, it is clear that our sleep has deteriorated and that many French people sleep poorly, for various reasons.
Poor sleep can negatively impact weight
People who sleep little tend to gain more weight. Moreover, prolonged lack of sleep would be one of the risk factors for obesity.
It is believed that the effect of sleep on weight gain is influenced by many factors, including hormones and motivation to exercise. In addition, there are natural solutions like CBD, which has the advantage of promoting sleep while promoting weight loss (products available online at this link).
Good sleepers tend to eat fewer calories
Studies show that people deprived of sleep have a greater appetite and tend to consume more calories. Indeed, lack of sleep disrupts the daily fluctuations of appetite hormones and is believed to be the cause of appetite disturbances. This is why people who lack sleep are more likely to have higher levels of ghrelin, the hormone that stimulates appetite, and reduced levels of leptin, the hormone that suppresses appetite.
Good sleep can improve concentration and productivity
Sleep is important for various aspects of brain function. This includes cognitive functions in general, concentration and productivity. All of these aspects are negatively affected by sleep deprivation.
Good sleep optimizes athletic performance
Sleep has been shown to improve athletic performance. In a study of basketball players, longer sleep was shown to significantly improve speed, accuracy, reaction times, and mental well-being.
Conversely, players lacking sleep have seen their sports performance drop significantly.
Lack of sleep increases the risk of heart disease and stroke
The quality and duration of sleep can have a major effect on many health risk factors. These are the factors that are believed to be the cause of chronic illnesses, especially heart disease. Indeed, during our sleep, our blood pressure drops, which allows the heart and blood vessels to rest a little. The less sleep you get, the higher your blood pressure stays during a 24-hour cycle.
A review of 15 studies found that people who don't get enough sleep are much more prone to heart disease or stroke than those who sleep 7 to 8 hours a night.
Sleep affects glucose metabolism and the risk of type 2 diabetes
Lack of sleep affects blood sugar levels and reduces insulin sensitivity. Indeed, in a study of healthy young men, restricting sleep to 4 hours per night for 6 consecutive nights caused symptoms of prediabetes. However, these symptoms disappeared after a week of increasing the duration of sleep.
Poor sleep habits are also strongly linked to the detrimental effects on blood sugar in the general population. To this end, it has been repeatedly shown that people who sleep less than 6 hours per night have an increased risk of type 2 diabetes.
Sleeping well improves mood
During the night, our brain processes our emotions. Our mind needs this time to recognize and react in the right way during the day. When we decrease this time of cerebral rest, we tend to have more negative emotions.
Chronic sleep deprivation can also increase your risk of suffering from a mood disorder. A large study has shown that insomnia increases the chances of developing depression five-fold.
Sleep helps strengthen your immune system
Our immune system identifies harmful bacteria and viruses in our body and destroys them. A permanent lack of sleep changes the way our immune cells work and they work less efficiently.
Sleep improves our social and emotional intelligence
Sleep has links with emotional and social intelligence. A person who does not get enough sleep is more likely to have difficulty recognizing the emotions and expressions of others. In fact, a study published in the Journal of Sleep Research looked at people's reactions to emotional stimuli. Researchers have concluded, like many previous studies, that a person's emotional empathy is lower when they don't get enough sleep.
Sleep helps regulate inflammation
There is a link between getting adequate sleep and reducing inflammation in the body.
Study suggests a link between sleep deprivation and inflammatory bowel disease that affects people's gastrointestinal tract. The study showed that insufficient sleep can contribute to these illnesses - and that these illnesses, in turn, can contribute to insufficient sleep.
Sleep is therefore a vital, often overlooked, part of the health and general well-being of every person. Sleep is important because it allows the body to repair itself and be fit and ready for another day. Adequate rest can also help prevent excess weight gain, heart disease, and increased duration of illnesses.
