We've talked a lot about blocking light at night. But the other half of a healthy circadian rhythm happens hours earlier — in the sunlight you get, or don't get, during the day.
Daylight is the anchor your body clock needs
Your circadian rhythm doesn't just respond to darkness at night; it calibrates itself against bright light during the day. Morning and daytime sun exposure is one of the strongest, most well-documented signals your body uses to set the timing of melatonin release later that night. Get that signal early and consistently, and your body has a much easier time knowing when it's actually supposed to wind down.
This is backed by real research, not just intuition: studies on morning light exposure consistently show improvements in sleep onset, sleep quality, and next-day alertness. It's one of the simplest, most accessible tools for supporting your sleep — and it costs nothing.
Why daytime light matters even if you're careful at night
You can have the best evening wind-down routine in the world — blackout masks, no screens, a dark room — and still struggle with sleep if your days are spent entirely indoors under artificial lighting. Your circadian clock needs contrast: bright, natural light during the day and genuine darkness at night. Without the daytime half of that equation, the nighttime half has less to work with.
Practically, this doesn't require anything extreme. A short walk outside in the morning, natural light near a window during the day, or simply choosing to eat lunch outside when you can all reinforce the daytime signal your circadian rhythm relies on.
Where sun protection still matters
None of this is an argument against sun protection. Skin cancer risk from UV overexposure is well established, and sunscreen and sunglasses remain appropriate tools for protecting your skin and eyes during prolonged or intense sun exposure — that guidance hasn't changed. The point here isn't to avoid the sun; it's to make sure you're getting some daylight exposure at all, especially in the morning, as part of a rhythm that also includes real darkness at night.
That's the other half of what VERALAS is built around: our silk masks and lavender routine handle the night. Getting outside during the day is the piece only you can do — and it makes everything else work better.
