Bright Light May Boost Testosterone Leave a comment

April 22, 2003 — Waking up to bright light may trigger a rise in male hormones that seem ease sexual brokenness and other side effects of depression. A unused shows that early morning light therapy caused a surge in a pituitary hormone called luteinizing hormone (LH) that raises testosterone levels in men.

Previous considers have appeared that bright light treatment of every day exposure to specially designed, high-intensity light boxes can lighten numerous indications of sadness, especially among people who suffer from seasonal affective disorder (Pitiful) during winter months.

Researchers say sexual dysfunction, including misfortune of libido and diminished sexual action, are commonly detailed symptoms among people with misery as well as visit side effects of upper solutions.

In this think about, distributed in the current edition of Neuroscience Letters, analysts examined levels of LH following one hour of bright light treatment (1,000 lux) from 5-6 a.m. for five days in a push among 11 solid men ages 19-30. The same group too was uncovered to a fake treatment light (less than 10 lux) over a comparable period.

Researchers found that LH levels expanded by 69.5% after bright light therapy, but those levels were unaltered after placebo light exposure.

The ponder also looked at whether levels of the hormone melatonin, which rises at night and is thought to play a role in the natural sleep cycle, could be affected by light therapy. Past ponders in animals had recommended that melatonin might meddled with a light therapy-induced LH boost, but analysts found no prove of this impact in humans.

Analyst In-Young Yoong, MD, PhD, who conducted the ponder at the University of California, San Diego, and colleagues say their findings propose bright light therapy may not only ease sexual brokenness in men, but it may too trigger ovulation in ladies, which is also controlled by LH.

Researchers say future studies should look at the effect of light therapy on LH levels in discouraged people to see in case it has the same hormone-raising impact found in these healthy volunteers.
