Insomnia is a sleep disorder characterized by the inability to fall asleep. But waking up at night twice or thrice is not linked with any sleep disorder. You must also be aware about the pros and cons of various sleeping position for your health. Health experts believe that 8 hours of sleep is not necessary for healthy body and brain. Waking up during the night might be caused by some health problem or sleep disorder in some cases. But the new research suggests that waking up at night is actually good for health.
Segmented sleep is not a sleep disorder but a natural phenomenon.
People used to practice segmented sleep in the ancient times. Whenever they used to wake up at night, they used to complete the house jobs or do meditation.
The literature from the period of Industrial Revolution also mentioned about the health benefits of first and second sleep.
The period between these sleep is quite productive as brain releases a hormone of relaxation called prolactin at that time.
The phenomenon of waking up in the middle of the night and then sleep later is known as sleep maintenance insomnia. This sleep disorder is actually a sleep condition which is caused due to lack of segmented sleep.
Our ancestors used to practice segmented sleep because it is actually beneficial for body and brain. Although they used to wake up at night due to lack of amenities such as electricity, their body used to retort to the nature perfectly.
