ClockNews #28: Asthma, Constant Light and Insomnia

Time Allergy and Asthma Medications for Best Effect

Allergy and asthma sufferers can maximize the benefit of their
medications by taking advantage of their bodies' natural circadian rhythms,
according to Richard Martin, M.D., Professor of Medicine at National Jewish
Medical and Research Center.

Body clocks response to constant light

Constant light has long been understood to disrupt our internal
clocks, resulting in problems like jet lag and health problems in extended-shift
workers. A study led by Vanderbilt researcher Douglas McMahon reveals that
although the clocks of individuals exposed to constant light may get out of
synch, they keep ticking.
synchronization of our internal biological clocks has important health
consequences. For example, babies held in the neonatal intensive care unit under
constant dim light can show lower weight gain than those on a more natural light
cycle. Repeated jet lag can also have adverse health effects.

Habits may cause insomnia

"The majority of people say they always have slept fine until
recently. Almost all kids sleep pretty well and wake up annoyingly perky and go
to bed and get up when mom and dad tell them.It’s only later on that people need
to use medications and they have sleep disturbances," said McNally.
