Is Your Dog S.A.D.?

Most of us are familiar with the Winter Blues- feelings of sadness, depression, and lethargy that can last the whole winter.  The Winter Blues are officially known as Seasonal Affective Disorder, or S.A.D.  It is caused by a reduced amount of sunlight during the winter.  In northern climates, where there is less sunlight during winter than in southern climates like ours, S.A.D. affects people at a higher rate.  But even here in South Texas, we can be affected by it.  A study showed that 2% of the Florida population is affected by S.A.D, and in New Hampshire it affects 10%.  S.A.D. is caused by the effect that the reduced amount of sunlight has on hormones.  Reduced sunlight causes an increase in melatonin (a hormone which is produced at night that causes sleepiness and lethargy) and a decrease in serotonin (a hormone which is produced in daylight and  regulates appetite, mood, and sleep and is used in antidepressant medications).  The recommended treatment for S.A.D. is often light therapy, also known as phototherapy.  This is where you spend a certain amount of time each day in front of a lamp that simulates daylight.  However, some experts agree that any modern compact fluorescent white light bulb that is advertised as being “full spectrum” or “daylight” is just as effective.

lunaThe suggested therapy for dogs is similar to that for humans- when your dog is indoors, use full-spectrum light bulbs that simulate daylight.  Also, put your pet’s bed near a window or skylight to make the most of what little natural sunlight there is.  In addition to this, if it is possible and your schedule allows, try to take your dog for a walk or let your dog outside during the brightest daylight hours.  By helping your dog, you will be helping yourself as well.
