Yes, exposure to artificial light at night can negatively impact the immune system. Here’s how:
**Disrupts Melatonin Production** – Melatonin is a hormone that regulates sleep and has antioxidant and immune-boosting properties. Artificial light, especially blue light from screens and LED bulbs, suppresses melatonin production, reducing its protective effects.
**Alters Sleep Quality** – Poor sleep weakens the immune system, making the body more vulnerable to infections and inflammation. Inadequate sleep reduces the production of immune cells and antibodies needed to fight off illnesses.
**Increases Inflammation** – Studies suggest that nighttime light exposure can trigger chronic inflammation, which is linked to various health issues, including a weakened immune response.
**Affects Circadian Rhythms** – The body’s natural sleep-wake cycle (circadian rhythm) regulates immune function. Artificial light at night can disrupt this rhythm, leading to immune system dysfunction.
To reduce these risks, avoid bright screens before bed, use warm/dim lighting in the evening, and consider blackout curtains or sleep masks to minimize light exposure.
Verdict: True. Artificial light in the room while we sleep can negatively impact our health.
