"DST has mixed effects on health. In societies with fixed work schedules it provides more afternoon sunlight for outdoor exercise.[70] It alters sunlight exposure; whether this is beneficial depends on one's location and daily schedule, as sunlight triggers vitamin D synthesis in the skin, but overexposure can lead to skin cancer.[71] Sunlight strongly influences seasonal affective disorder. DST may help in depression by causing individuals to rise earlier,[72] but some argue the reverse.[73] The Retinitis Pigmentosa Foundation Fighting Blindness, chaired by blind sports magnate Gordon Gund, successfully lobbied in 1985 and 2005 for U.S. DST extensions,[3][74] but DST can hurt night blindness sufferers.[75]
Clock shifts disrupt sleep and reduce its efficiency.[10] Effects on seasonal adaptation of the circadian rhythm can be severe and last for weeks.[76] A 2008 study found that although male suicide rates rise in the weeks after the spring transition, the relationship weakened greatly after adjusting for season.[77] A 2008 Swedish study found that heart attacks were significantly more common the first three weekdays after the spring transition, and significantly less common the first weekday after the autumn transition.[78] The government of Kazakhstan cited health complications due to clock shifts as a reason for abolishing DST in 2005.[79]"
