Where Can I Find High Quality Ozone Lamps?

uv curing bulbs

Ozone occurs naturally from ultraviolet light although the ozone layer filters most of the UV light emitted by the sun.  Ultraviolet (UV) light refers to wavelengths emitted at frequencies higher than visible light. Ultraviolet, or beyond violet, refers to light frequencies in the range of 100 to 315 nm, whereas visible light is in the range of 400 to 700 nm.

UVC germicidal lamps deliver powerful UV radiation at an effective 254 nm, proven to sterilize and disinfect against many germs and viruses. When UV light is emitted in shorter wavelengths in the range between 160 to 240 nm, ozone will be produced.  Photolysis of oxygen, O2, is the process which disrupts the oxygen molecule, creating valent oxygen atoms which attach to individual oxygen molecules, creating ozone, O3.  

Quartz glass ozone lamps emit UV rays in the range of 185 nm to effectively decompress the oxygen in the air and create ozone.  Ozone disinfectant lamps are used worldwide in a number of water and air sterilization systems, eliminating harmful germs and foul odors.  UVC ozone lamps improve air quality by eliminating harmful contaminants, microorganisms, volatile organic compounds (VOCs) including ammonia, sulfides and mercaptans.

Light Therapy for Mood and Sleep Disorders

LS post 68

Light therapy, also called phototherapy, is a way to treat various mood disorders and depression, specifically seasonal affective disorder (SAD).  SAD commonly occurs to people that live in the northern hemisphere during fall and winter months when sunlight is significantly reduced. People that use light therapy to ease symptoms of SAD sit next to a bright light that mimics natural outdoor sunlight.

According to the Mayo Clinic, light therapy can be quite successful in treating a number of mood and sleep disorders including:

  • Seasonal Affective Disorder, SAD
  • Nonseasonal types of depression
  • Sleep disorders
  • Dementia
  • Adjustment to night work schedules

Phototherapy is thought to successfully treat these disorders by affecting chemicals in the brain which are linked to mood and sleep.  Light therapy is also used to treat many different skin conditions such as acne, eczema and psoriasis although those UV phototherapy lamps are different from light therapy lamps for SAD. 

Light therapy lamps for mood and depression should filter out UV wavelengths which can damage your skin and eyes. Some people may think that using a tanning bed is good enough to treat seasonal and nonseasonal depression, although this is a myth.  Tanning beds are not an alternative to phototherapy lamps and will increase your chances of developing skin cancer.

Reasons You May Want to Try Phototherapy

Phototherapy can provide many benefits to improve symptoms of SAD, depression and sleep problems. It is a good idea to talk with your doctor about light therapy and the reasons why you’d like to try it. Be sure to purchase a quality phototherapy lamp designed to treat the symptoms you desire and be aware of any risks involved.

You may want to try light therapy for many reasons such as:

  • Your doctor recommends light therapy for seasonal depression
  • Your doctor recommends combining light therapy with antidepressants
  • You need to avoid taking antidepressants During pregnancy or breast-feeding
  • Light therapy is safe with few side effects

Phototherapy can provide many benefits when used in combination with antidepressants and or psychological counseling.  If you experience side effects they usually do not last long and may include mild symptoms such as:

  • Headache
  • Eyestrain
  • Agitation or irritability
  • Nausea
  • Manic or euphoric state associated with bipolar disorder

Talk with your doctor if you experience any of these symptoms or have concerns about light therapy affecting your thoughts or mood such as experiencing mania or hyperactivity. It is important to talk with your doctor about using light therapy for mood and sleep disorders, especially if you have any conditions that make your skin or eyes sensitive to light. Some anti-inflammatory medications and antibiotics can increase sensitivity to sunlight along with some herbal supplements like St. John’s Wort.
