Why do we feel more relaxed and happy after a session? From β endorphins to serotonin, this is what happens to the brain.
That feeling of relaxation and slight euphoric well-being that you experience after a session is not a placebo. Controlled exposure to UV rays triggers a biochemical chain that culminates in the release of β endorphins and the production of serotonin, two key neurotransmitters for mood.
1 - The light-skin-brain cycle
- UV B rays convert 7 dehydrocholesterol into vitamin D.
- This process stimulates keratinocytes to release β endorphins.
- The β endorphins reach the brain via the blood and bind to opioid receptors, generating a feeling of well-being.
2 — Scientific data
A JAMA Dermatology study (Fell et al., 2014) showed +44 % plasma β endorphin after 6 minutes of UV exposure compared to filtered light. Another trial of 100 subjects showed a significant decrease in the SAD (Seasonal Affective Disorder) score after three weeks of controlled sessions.
3 - Serotonin & circadian rhythm
Bright light (over 10 000 lux) inhibits daytime melatonin and increases serotonin. Although the solarium does not replace classic light therapy, an 8-10 minute cycle (solarium Type 3) provides the brain with sufficient light stimulation to improve alertness and motivation.
4 - Guidelines for exploiting the mood boost effect
- Timing: session between 10:00 and 14:00 to synchronise sleep-wake rhythm.
- Frequency: 2 sessions/week are sufficient; avoid daily use.
- Duration: respect the Skin Control minutes; the endorphin effect is dose-dependent but saturates after 15 minutes.
- Post-session: hydration and brief light physical activity (walking) amplify serotonin.
5 - Who benefits most
- Office workers exposed to little natural light.
- People with mild 'winter blues' or seasonal energy loss.
- Athletes seeking post-training muscle relaxation.
Conclusion
The Blue Light solarium, with its controlled timing and Type 3 solarium, not only offers a golden complexion: it is also an ally for mind and energy when the sun is scarce.
Give yourself a 'mood boost' break: treat yourself to a 10-minute session, leave with an extra smile and your skin ready for the weekend!
