SAD Lamp
I want information about...
- wellbeing, mood, sleep, and energy levels during winter
What can it be used for?
A daylight therapy lamp and a Seasonal Affective Disorder (SAD) lamp are very similar, but not always exactly the same.
Both are designed to mimic natural sunlight and are used to help regulate mood, sleep, and energy levels - especially during darker months.
Daylight Therapy Lamp:
- A general term for lamps that emit bright, white light similar to daylight.
- Used for various purposes including improving alertness, sleep cycles, and mood.
- May not always meet the clinical standards for treating SAD.
SAD Lamp:
- Specifically designed to treat Seasonal Affective Disorder.
- Emits 10,000 lux of light (a key therapeutic intensity).
- Filters out UV rays to protect your eyes and skin.
- Often used for 30 minutes in the morning to simulate natural sunlight exposure.
You can buy these from some shops which sell lighting, electrical items or health and wellbeing products, or search on the internet for a 'daylight therapy lamp' or 'SAD lamp'.
Benefits
- Improves wellbeing: Mimics natural sunlight, which may trigger a chemical change in the brain to lift mood and reduce symptoms of depression. Can help with fatigue and sleep by helping to regulate circadian rhythms. Circadian rhythms are the body’s natural clock that tells you when to wake up, feel alert, and go to sleep - based mostly on light and dark.
- Convenient: Can be used at home, typically for 20-30 minutes each morning.
Things to Consider
- Suitability: All SAD lamps are daylight therapy lamps, but not all daylight therapy lamps are suitable for treating SAD. If you're considering one for SAD, make sure it’s 10,000 lux, UV-free, and ideally certified for medical use. To certified for medical use the device must be registered with the MHRA or carry a CE/UKCA mark, confirming it meets medical device regulations. If the person intending to use it has bipolar disorder, eye conditions (like glaucoma or cataracts), or light sensitivity, they should consult a doctor before use.
- Timing and Duration: Best used in the morning, following the instructions that are provided with the light. There is the risk that side effects could occur which include eyestrain, headache, nausea, or irritability, especially if used too long or too close. It is important to use it as per the instructions.
- Cost and Value for money: Costs can vary. Check reviews, consider if there is a warranty and what customer service is like.
