When your sleep is interrupted, it is much likely to affect your mood and general well being than less sleep says a recent study. In this study conducted by researchers at the John Hopkins School of Medicine, Baltimore, they studied 62 men and women dividing them into three experiments. One group was made to wake up forcefully from their deep sleep, others were made to sleep late and the last group slept peacefully in an uninterrupted environment. The researchers studied the participants over a period of three days and and then published their findings in the journal Sleep, reports Independent. The group that was continuously interrupted from their sleep reported lower levels of positive mood and the second group reported 31% reduced levels of anxiety due to lack of sleep. The most significant finding was revealed in the group that had shorter periods of deep sleep affecting the energy levels.

According to the National Sleep Foundation, the adults aged between 18 and 64 should aim to get at least 7-9 hours of sleep every day for increased productivity. The foundation claims that getting enough sleep is very helpful in boosting the immunity system, enhancing the mood and increasing productivity. However, more and more studies prove that more than the duration of the sleep, it is important to have quality sleep. "When your sleep is disrupted throughout the night, you don't have the opportunity to progress through the sleep stages to get the amount of slow-wave sleep that is key to the feeling of restoration," says lead author Patrick Finan, assistant professor of psychiatry and behavioral sciences at John Hopkins University School of Medicine. The study used the experiments to display the effects of poor sleep on the brain and mood, reports Medical News Today.
