Constant Daylight Leads to Insomnia, Suicide
New research in the journal BMC Psychiatry claims constant sunlight may cause sleep disturbances, leading to insomnia and ultimately raising suicide risk. For the study, scientists analyzed suicides in Greenland between 1968 and 2002, finding a cluster of suicides during summer months when the days are longer. Experts speculate days of constant sunlight may cause an imbalance of brain chemicals linked to mood and when paired with lack of sleep, could be deadly; Reuters investigates.
I’d have to put tinfoil on the windows! Dr. Fuhrman told me it’s about balance. Sunlight is necessary, our bodies convert the sun’s ultraviolet rays into vitamin D, which improves bone health, but sleep is important too. When we sleep our body removes brain waste and this allows for normal function of the nervous and endocrine systems.
In related news, expectant mothers getting enough sun are more likely to have children with stronger bones and sunlight helps older people avoid depression.
