Pregnant mothers who have not shied away from sunshine during pregnancy will be greatly benefited for they go on to have taller babies.
The 18-year project found that babies born in late summer and early autumn are around half a centimetre taller and have wider bones than those born in winter and spring, reports the Scotsman.
Researchers at Bristol University recommended that winter parents should consider taking vitamin supplements.
A study spokeswoman, Sally Watson, said: "Perhaps people shouldn't be quite so terrified of the sun.
"There's been a lot of panic about skin cancer, but people don't need to panic about the odd few minutes of exposure.
"A little controlled English sun is better than none."
