Scientists of the University of California have discovered new negative consequences of insufficient sleep. It turns out that sleep deprivation leads not only to a bad mood, lethargy and obesity, but also can cause diseases such as asthma, cancer and arthritis.
People whose sleep was less or more than the recommended 7-8 hours, had increased concentration of inflammatory proteins in blood. Such biomarkers are associated with various diseases – diabetes, hypertension, asthma and depression. The authors suggest that sleep disorders may be a risk factor for the development of certain diseases, as they affect the immune system.
Lack of sleep affects both mental and physical health
Over the past few years, surveys on sleep showed obvious sleeping problems According to the result, only half of adults have normal healthy sleep almost every night. Two of the six adults sleep less than seven hours a day.
It’s not a secret that we are a part of society and spend much time in it. There are so many temptations that replace sleep – cable TV, Internet, e-mail, chat rooms, plus long work shifts. The way we live is reflected on our sleep. Often sleep deficits are associated with the use of large amounts of caffeine, nicotine, and alcohol.

- Problems at work or in the family;

There is evidence that sleep deprivation is a serious problem.
Effects of sleep deprivation on the body:

Eight of ten couples say that their partner has sleep problems such as snoring, insomnia or restless sleep. Other couples have reported that sleep problems are so serious that the couple had to sleep separately. About 20% say that hey have less sex or even lost an interest in it because of lack of sleep.
In addition, recent studies have shown the development of other serious diseases on the background of sleep deficiency:
- Cardiovascular diseases;
- erectile dysfunction.
People just do not realize the importance of sleep and the possible consequences of sleep deprivation. Sleep plays an important role in maintaining health, as well as, for example, nutrition and exercise.
In addition, people do not talk about their problems to doctors. They think that everyone always wants to sleep, and nothing can be done about it. And doctors do not ask about it. Timely sleep disorders diagnosis and treatment is very important.
Symptoms of nighttime asthma are the following:
- Chest tightness;
- shortness of breath;
Asthma cough at night leads to sleep disturbances, resulting in feeling tired next day. Nocturnal asthma is a serious condition that requires an accurate diagnosis and effective methods of asthma treatment.

Asthma symptoms are aggravated during sleep. Many physicians underestimate nighttime asthma, however, such common symptoms as asthma cough at night and asthma attacks in sleep pose a potential threat to the life of the patient. Studies have shown that the majority of asthma deaths happens at night. Nocturnal asthma attacks can cause serious sleep problems:
- fatigue and irritability during a day.
They also have a negative impact on the general life quality and complicate the control over asthma symptoms during the daytime.
Sleep from a scientific point of view
Over the past decade, researchers have studied sleep mechanism carefully. Approximately 100 sleep disorders have been identified. Here are two of the main ones:
- Hypersomnia is a pathological increase in sleep duration. This disorder needs to be paid special attention to. The consequence of this phenomenon could be insomnia, which can cause weakening of long-held spotlight with sometimes dangerous consequences. Every year over 100,000 accidents happen due to driving in sluggish and drowsy state. The most common cause of hypersomnia is a voluntary renunciation of sleep because of social or economic reasons, such as work or “hanging out” on the Internet. We sleep 20% less than the previous generation. But there is no evidence that the previous generation needed more sleep.
- Insomnia is the most common type of sleep disorders which people complain for. This touches not sleep directly, but an ability to fall asleep and continue sleeping soundly. This is an inability to plunge into a long sleep, which should be long enough or “full” , so that the next morning we could feel rested and fresh for the whole day. Some people call depression is a cause of insomnia. But if insomnia is not treated, depression is inevitable.
Most people with sleeping problems also suffer from overexcitation, that means that a man is constantly ready and rarely sleeps. There is evidence that the majority of insomniacs have a systemic predisposition to hyperactivity 24 hours a day. They can not sleep, and then the whole next day are feeling miserable, tired, squeezed, having trouble concentrating. But it is not sleepy. They do not want to sleep, insomnia is always chasing them: they can not even sleep in the daytime.
Neurological scans show the difference between brain of a healthy man and a man suffering from insomnia. Scientists suggests that there is a genetic component of hyperactivity and insomnia.
Usually there is a genetic predisposition to insomnia. Most people struggle with it from childhood. They are small enough reasons for insomnia – a test the next day, the approaching holiday. At first glance, insomnia begins because of the rather banal reasons. In addition, sleep is very “fragile”, because such people are very prone to insomnia.
The consequences of insufficient sleep
At the health conference, the attention was focused on a chronic insomnia, including its huge impact on health (which is not often mentioned elsewhere). If children and adults (especially seniors) suffer from insomnia, all around suffer as well (parents, guardians). Employers are strongly affected, if they employ workers, who are, so called, night owls.
Basically, a person needs from seven to eight hours for a full recovery of the body and its functions. Of course, there are some exceptions. Some people need more time to rest than the others. And some people need short sleep. But such exceptions are rare.
If a person sleeps less than is required by his body, he may have serious consequences.
“Evidence has been found that chronic sleep deprivation increases the risk of early death“, – says Hunt. Research has shown that those who does not sleep, are at risk for cardiovascular disease and heart attacks. And one recent study has confirmed the link between asthma, chronic sleep deprivation and excess weight and obesity. These studies have made it clear that society pays a price for sleep neglect.
