Although spending a bad night from time to time may not be anxious, the sleep disorder continuously can lead to problems ranging from weak immunity, to anxiety and depression, to weight gain and chronic diseases, according to Metro.
How does sleep affect less than 6 hours on the body?
The immune system is severely affected
During sleep, the body produces important immune substances known as cytokines, which are necessary to fight infections and viruses. When we reduce our sleep hours, the production of these substances decreases, weakening our ability to resist diseases.
A 2023 study showed that those who sleep less than 6 hours per night showed a weaker immune response to vaccine, especially between males and adults between the ages of 18 and 60 years.
Anxiety, depression and a vicious ring
Lack of sleep increases anxiety, and anxiety in turn exacerbates insomnia. The sleeping expert, Dr. Suo Picok, indicates that the brain remains in an ongoing state of anxiety, which impedes entry into a deep sleep. She adds that this continuous tension may weaken the ability to face emotional challenges or enjoy positive experiences.
Hormonal disorders in women
Dr. Katrina Lidirle, a sleeping and biological clock specialist, explained that the lack of sleep affects thyroid hormones, which leads to menstrual disorders, and may reach an interruption of ovulation or frequent miscarriage.
Overweight
Bad sleep disturbs the balance of hunger and satiety hormones such as leptin and grylin, which increases appetite and pushes to eat excessively, and thus leads to obesity.
Productivity is declining
Lack of sleep affects mental performance, memory, and attention. An American study showed that employees who sleep 5 hours a day lose more working days than their counterparts, who sleep 8 hours.
Public health is in danger
Lack of sleep may lead to heart disease, high blood pressure, strokes, diabetes, and even Alzheimer’s. Dr. Sue says: Sleep deprivation is not just temporary fatigue, but a long -term threat to your health.
