Sleeping With Bright Lamp Can Trigger Diabetes

A study conducted by Joshua Gooley, a health expert from Harvard Medical Scool in Boston said, sleeping with bright ambient conditions can increase the risk of type 2 diabetes. The study involved 116 participants aged between 18 to 30 years.

The participants were divided into 2 groups, one of which is conditioned to be in the room is brightly lit for 8 hours before bedtime. The other group was placed in a dim room with the same duration of 8 hours.

The result of examination of blood samples taken every 30 minutes showed the hormone melatonin production down 50 percent in participants who were in a bright environment. These hormones regulate related biological clock cycles between asleep and awake.


Besides triggering sleepiness, melatonin is also associated with some types of serious illnesses. Melatonin receptors located in nerve mentioned could increase the risk of cancer and type 2 diabetes if their activity is reduced.

"The study provides a big impact for night workers who are exposed to light throughout the night and then take a nap when the sun shines bright," Gooley said as quoted from HealthDay, Monday (17/01/2011).
