Our bodies run on internal clocks called circadian rhythms, which tell us when to wake up and when to sleep. These clocks are heavily influenced by light—especially the kind we’re exposed to during the day versus at night. New research suggests that when and how much light we get might play a bigger
Daytime sunshine plays a key role in keeping our bodies’ internal clocks ticking smoothly. When we don’t get enough natural light, these rhythms can become out of sync, and that may raise the chance of serious illnesses like cancer. A large study followed almost 90, 000 adults for nearly nine years,
Ever wondered why your body clock seems to go haywire when you work shifts? It turns out, the math models that predict our internal rhythms do well in labs but struggle in the real world. This is especially true for shift workers whose light exposure is all over the place. Researchers dug into this

Dentists have a unique chance to help with skin cancer. They look at the head and neck every day. This is important because most skin cancers show up in these areas. Why? Too much sun exposure. The sun's ultraviolet light can damage skin cells over time. Dentists are great at spotting issues in the
The night sky is no longer dark. Artificial light has taken over. This might seem harmless, but it could have serious effects on our health. One big worry is the link between nighttime light exposure and breast cancer risk. Light at night, especially the blue kind, messes with our bodies' natura
The time of year when a baby is born can affect their growth. This is especially true for kids born in Estonia between 1937 and 1962. The amount of sunlight a mother gets during pregnancy can change the nutrients available to the baby. This includes vitamin D and other important minerals. However, i
Did you know that light can affect the brain? A recent study explored how different light levels influence rat brain tissue. Researchers used 32 male Wistar Albino rats, splitting them into four groups: Control, Light, Dark, and Dim Light. Each group had 8 rats and was exposed to their respective co
