Have you been bothered by feeling down lately, struggling to have interest or pleasure in doing things you usually enjoy? While there may be many reasons why you’re not feeling like your normal self, there likely are some key symptoms you’re experiencing that aren’t helping you see the light (excuse the pun!), such as lacking energy, sleeping poorly, or finding it hard to muster the motivation to blaze through your to-do list. As a result, your daily rhythms become more and more out of whack, affecting your ability to function optimally and feel well.
How are circadian rhythm and mood linked?
Your body’s circadian rhythm is affected by how much light (natural and artificial) you’re exposed to. Light exposure to the retina is first relayed to the area of the brain responsible for coordinating your body clock (hypothalamus), before descending to your pineal gland (located in the epithalamus). Your pineal gland transduces signals from the sympathetic nervous system into a hormonal signal, which results in the production of hormones such as serotonin (the happy hormone) and melatonin (the sleep hormone).
In fact, your body needs serotonin to produce melatonin, as your pineal gland chemically alters one hormone to create the other in a process called synthesis.
How can light therapy help?
Studies suggest that the brains of people with depression often produce too much melatonin, causing circadian rhythm disruptions. Exposure to the right light at the right time of day is key in coordinating biological clock signals. Research shows that bright light therapy in the morning or early afternoon has tangible, physiological effects on our bodies and brains by suppressing melatonin production, thus contributing to enhancing alertness, improving sleep and waking, and boosting serotonin. Opting for dimmer lights with reduced or low blue light content in the evening is recommended to encourage the melatonin levels to rise naturally.
