A clear dose response relationship between light intensity and clinical benefit emerged from a meta-analysis of 39 comparative studies. Strong light of 6000 to 10 000 lux works better than medium light −1700 to 3500 lux—and both work better than dim light. Typical depressive symptoms respond best to treatment.
Teenage girls who drink plenty of milk may end up with higher peak bone mass as adults, say investigators from the USA who questioned over 224 women about their childhood and adolescent calcium intake (American Journal of Clinical Nutrition 1999;69:1014-7).
