How to Work at Night, Productively

In our post-industrial society, artificial lighting has become a cornerstone of modern living. Yet this pervasive light exposure carries real risks for our health — and above all for the sleep that decides how well we work the next day.

Understanding the effects of lighting on melatonin

Melatonin is the hormone that tells your body it is time to wind down. Light is the single biggest thing that suppresses it — but not all light is equal.

Overhead lighting

Overhead lights, though essential for daily activities, disrupt natural circadian rhythms by creating a perpetual daylight environment. Even a small amount of light in the room can hinder melatonin production, making it harder for your body to settle into a restful state.

Fluorescent and LED lighting

These sources emit substantial blue light, which suppresses the melatonin essential for regulating sleep. Their widespread use since the invention of the lightbulb has been linked to increased risks of obesity, depression, sleep disorders, and even diabetes.

Candlelight

Candlelight, with its warm and dim glow, is a gentler alternative — helping maintain melatonin and promote relaxation. Comprehensive research on burning candles and sleep is limited, but their calming effect is well-regarded for a restful pre-sleep environment.

Practical steps to optimise light exposure

1. 1

   Apply red light filters on your devices

   • iOS / macOS — Settings → Accessibility → Display & Text Size → Colour Filters, and enable a red hue. Night Shift (under Display & Brightness) also cuts blue light in the evening, though it is less effective. With the Shortcuts app you can automate the filter to switch on after sunset and off before sunrise; on Mac you may not be able to automate it, but you can make a shortcut button.
   • Android — Open Display settings to turn on Night Light or Blue Light Filter. Apps like Twilight add further control, letting you shift the screen to deeper red tones.
2. 2

   Use red lighting in your environment. Replace overhead lighting with red or RGB LED bulbs to cut blue light exposure in the evening. This small change can meaningfully improve sleep quality by supporting natural melatonin production.

3. 3

   Automate your light settings with technology

   • f.lux — Adjusts your screen's colour temperature to the time of day, reducing blue light at night.
   • IFTTT & Tasker — Automate device settings to enable red filters or dim the screen based on your local sunset time.
   • Philips Hue — Some smart bulbs — Hue and Wiz among them — offer circadian lighting that shifts colour temperature through the day. Just be sure to switch it on.
4. 4

   Embrace candlelight. Bring candlelight into your nightly routine to create a calm, low-stimulation atmosphere in the hour before sleep.

Integrating Solah's values

These lighting adjustments align with Solah's mission to harmonise health practices with spiritual observance. Optimising light exposure supports both productivity and spiritual wellbeing, fostering a balanced, fulfilling life.

Yet light is only one facet. True health draws on many elements, and aligning your life with them is essential — without habits like a consistent sleep–wake schedule, you may still wake up tired each morning. Solah guides you through this comprehensive view in phases, so every part of your wellbeing is attended to.

Work with the night, not against it

By understanding how different lighting affects sleep, and using the right tools to manage it, you can craft an environment that protects your rest and sharpens your daily performance.

Solah is built to be your partner on that journey — harmonising your daily routines with both spiritual and scientific insight, so your nights are restful and your days productive and aligned.
