For many parents, getting their baby to sleep at night can become
a daunting task. Often times it seems that nothing will help; however,
researchers may have discovered a natural remedy: Sunlight.
According to a study, babies exposed to twice as much light during
the day (between noon and 4 pm) became better sleepers at night.
The study consisted of 55 babies who were
monitored for three successive days at the age intervals of:
- Six weeks old
- Nine weeks old
- 12 weeks old
Throughout the study, a light monitor was attached to each of the
babies' cribs. Parents were advised to go about their usual routines,
as well as keep a diary of their baby's sleep and crying patterns.
One theory explained the connection between light exposure and
sleeping by stating that higher light levels encourage early development
of the biological clock. This natural body clock regulates a wide
range of bodily functions, such as the secretion of melatonin. Melatonin
not only promotes sleep, but also plays an important role in well-balanced
sleeping patterns.
Based on their findings, researchers concluded that healthy doses
of daylight encourage babies to sleep at night. Thus, parents are
advised to take their babies out in sunlight.
