New Delhi: It used to be a routine practice in India to massage infants and give them a sunbath. But changing lifestyles in recent decades have confined kids to indoors. This has led to emergence of Vitamin D deficiency as a major problem among infants.
A study from Delhi has suggested an estimate for the minimum duration for which infants need to be exposed to sunlight every day to achieve sufficient levels of vitamin-D in their body.
Doctors at the University College of Medical Sciences, New Delhi enrolled 100 infants and asked their mothers to record the time, duration, and the body area exposed during sunbath every day starting 6 weeks of age.
The study found that an exposure of as low as about 30 minutes of sunlight per week with about 40% of the child’s body exposed to the sunlight can help achieve adequate vitamin-D status at 6 months of age. The researchers also found that the ideal time to give the sunbath is between10 AM and 3 PM.
