There's something in the air, and it's not just pollen. Spring
break, spring vacation, spring weddings -- spring fever. We want to get out,
wear less, mingle lots. Kids feel it, too. Talk to any teacher, you'll likely
hear there's craziness in the classrooms.
That energy surge, in whatever form it takes, is a function of
longer days and lots more sunlight, says Michael Smolensky, PhD, professor at
the University of Texas-Houston School of Public Health. He is co-author of the
book The Body Clock Guide to Better Health.
Stress incontinence has an annoying way of showing up at the most
You're jogging along, feeling great -- and then you realize your running
shorts are damp with urine. Later that night, during a romantic rendezvous with
your partner, a trickle of urine appears again, definitely spoiling the
Lest you think stress incontinence is a problem only of middle-aged or
elderly women, think again. Surprisingly, young women actually have more stress
In fact, many facets of everyday life are governed by seasonal
patterns as well as circadian rhythms -- our internal biological clock,
Smolensky tells WebMD.
"These are the rhythms of life, and we take them for
granted," he says. "People accept the fact that our bodies are
organized in space -- that our toes are at the end of our feet, and the hairs
on our head stand up. But we give little thought to the fact that our bodies
are structured in time."
Spring Brings Changes in Hormones
When seasons change, the retina -- the inner layer of the eye
that connects to the brain through the optic nerve -- naturally reacts to the
first subtle signs in the amount of daylight, says Sanford Auerbach, MD,
director of the Sleep Disorders Center at Boston University. This reaction
triggers hormonal changes, including an adjustment in melatonin, a hormone that
affects sleep cycles and mood changes.
During the long darkness of winter months, the body naturally
produces more melatonin. For people prone to seasonal affective disorder, all
that melatonin triggers a winter depression. In spring, when melatonin
production eases up, so does depression.
"There's more daylight, so people have more energy, sleep a
little less," Auerbach says. "People who have manic-depressive problems
[bipolar disorder] may be more manic in springtime."
Body image springs into our consciousness this time of year.
We're shaking that craving for carbohydrates that makes us put on weight, says
Smolensky. "It's likely a carryover from our ancestors who had a
hibernation-type biology. In the fall, they began putting on weight to get
through the lean times of winter."
