Here Are Some Serious Repercussions of Sleeping Less Than 7 Hours a Night

The human body needs its restorative sleep to function accordingly. Having a good night sleep is of great essence for having an optimal health. If that is not the case the body will start to experience certain disturbances that will eventually lead to the rise of various health issues. Not to mention the fact that after having a sleepless night the affected person feels moody, sleepy and not being able to perform its daily tasks.

Due to the rise of the modern technology people are more and more having sleepless nights. The addiction to the blue screens of the phones or laptops contributes to this sleep disorder. Their influence disturbs the production of the melatonin, a hormone accountable for sleeping which results in lack of sleep. The human body needs at least 8-hour sleep in order to regenerate itself and function optimally. In the case of sleep deficiency there are consequences on the health and well-being of the body.

The Negative Effects of Sleep Deficiency

  1. Higher risk of cardiovascular disease

As per conducted study researchers have discovered that people who lack sleep suffer from higher blood pressure and heart rate. Sleep deficiency leads to a high concentration of C-reactive protein which is an important marker of a cardiovascular disorder.

  1. Lower immunity

While sleeping the body is resting and in that period the immune system regains its strength and thus functions accordingly. Not enough sleep reduces the body’s defenses almost immediately. As per a conducted study on 42 participants who did not have a restful sleep there has been obvious reduction in the immune system response.

  1. Low concentration

As a result of a sleepless night the concentration in the upcoming day is substantially lower.  According to NHS UK, sleep deficiency prevents the brain from seeing things clearly when there is the need for focusing which reflects on our ability to do the simplest tasks. Therefore, make sure to have a good night sleep in order for your cognitive faculties like memory and concentration to be at their optimal levels.

  1. Weight gain

When not having proper sleep the food cravings are higher, especially for high calorie meals. This urge is because we lack the energy but these food choices are unhealthy that will eventually lead to weight gain. According to researchers at the University of Texas this offsets an energy deficit in the metabolism which is one of the major causes of obesity.

  1. Depression

People who suffer from insomnia are twice as likely to suffer from depression as per a released report by The Journal of Affective Disorders. Many studies have confirmed this finding and because of that as a first step of treating depression is restoring good night sleep.

  1. Irritability

As a result of a sleepless night the affected person is more irritate and anxious during the day. As per conducted studies sleepless nights trigger negative reactions and decrease the impact of positive events on the brain. Hence, the increased irritability is inevitable in everyday events.

  1. Isolation and loneliness

Lack of sleep leads to loneliness and isolation, which will impede our healthy socialization with the other people. This commonly happens to the younger generation as they are trapped in this vicious circle which isolates them from other people. This affects their social relationships and the consequences are social isolation and feeling alone.

  1. Lower libido

Testosterone that is accountable for sexual desire is produced mainly while sleeping. So, when the body does not get its needed sleep the production of this hormone is being disturbed which leads to reduced libido. In such cases erectile dysfunctions are becoming a common issue that hinders the sexual fulfillment of the affected person.
