Lack of sufficient sleep may cause emotional problems such as losing temper and interpreting things negatively, according to new research.
Sandra Tamm of Department of Clinical Neuroscience at Karolinska Institutet did a study of 117 people using MRI and PET techniques to study how sleep deprived people react to emotional impressions. It was found that experimentally induced sleep loss caused negativity bias. It causes a more negative interpretation of emotional stimuli and impaired emotional regulation.
The study points to the need to have adequate rest and sleep to prevent emotional problems for developing and avoiding the risk of developing depression.
