Our reviewer sheds some light on the best dawn simulation alarms, from Lumie and Philips to Dreamegg

• The best eye masks to help you sleep better

To wake each day in darkness is a plight you wouldn’t wish on your worst enemy, yet that’s what many of us do routinely throughout winter. Getting up in the dark decouples our life from our circadian rhythm (our body clock), with bodily processes such as cognition and metabolism put to work before they’re fully prepped.

Thank heavens, then, for sunrise alarm clocks. These “dawn simulation” devices glow with gradually intensifying brightness as your wake-up time approaches, kickstarting your circadian rhythm before you get out of bed. For many users, this results in a happier, healthier start to the day.

Every other Tuesday, AJ Daulerio wakes up at 5.30am and meditates for five to 20 minutes before beginning his multistep daily journaling protocol: reading a selection from a poetry anthology, then a passage from one of his daily wisdom readers (his go-to is a heavily annotated copy of Leo Tolstoy’s A Calendar of Wisdom); writing his Fear of the Day and gratitude list, then sharing his spiritual takeaway in a note to his three kids.

After a banana and coffee, Daulerio trains Brazilian jujitsu before hitting a 9.45am meditation at Besant Lodge – a community center just below the Hollywood sign that once served as a meeting place for mid-century mystics – immediately followed by him leading a recovery meeting of his own through Zoom.
