1:47 am. Arjun, 33, is lying in bed with his eyes wide open.
His body is exhausted. His mind is not. Tomorrow's client call. The email he forgot to answer. The thing his manager said at 6 pm that may or may not have been a dig. A song from 2009.
It feels like a laptop with 40 browser tabs open, the fan whirring, too hot to close.
If you can't sleep at night like this, here is the first thing to know: your brain is not broken. It simply never got the signal to close the tabs.
Can't sleep at night? The usual insomnia causes
Adults need 7 or more hours of sleep a night for good health, according to sleep experts. Many of us get far less, and the reasons are usually ordinary:
- The day never ended: work messages till 11 pm keep your brain in office mode.
- Screens in bed: in one study, people who read on a glowing screen before bed took longer to fall asleep and felt less alert the next morning than those who read a printed book.
- Overthinking at night: the first quiet moment of the day is when every worry finally gets your attention.
- Late chai or coffee: caffeine can stay in your system for hours.

How to sleep better: close the tabs one by one
The tabs do not close by force. They close one at a time.
You cannot shout a brain into sleep. You close the tabs gently, with these simple sleep hygiene tips:
- Set a screen curfew: phone on the charger, outside arm's reach, 30 minutes before bed.
- Do a worry dump: write tomorrow's three biggest worries on paper. Your brain can let go of what is written down.
- Fix the wake-up time: wake at the same time daily, even on Sundays.
- Cut caffeine after 3 pm: switch the evening chai to warm haldi milk.
What research says about a calmer night
Magnesium for sleep: the dimmer switch
Magnesium is a mineral your body uses to calm nerves and relax muscles. Think of it as the dimmer switch on your brain's lights. In a study of older adults with trouble sleeping, magnesium supplements supported better sleep time and sleep quality compared with placebo.
A safety note on magnesium side effects: your kidneys remove extra magnesium from the body. If you have kidney disease, ask your doctor before any magnesium supplement. High doses can also cause loose motions.
L-theanine benefits: calm without drowsiness
L-theanine is a natural compound found in tea leaves. It is one reason a cup of tea can feel calming rather than jittery. In a four-week trial in healthy adults, L-theanine supported lower stress and better sleep quality, without making people feel sleepy during the day.
Remember Arjun's 40 tabs? Magnesium helps dim the lights. L-theanine helps quiet the chatter. Two different angles on the same restless night.

A calmer evening, in one drink
Daily Boost in you includes 100 mg of magnesium and 100 mg of L-theanine, along with other daily nutrients, in one lime-flavoured drink. Both have been studied for calm and sleep quality. It works best alongside your screen curfew and fixed wake-up time, not as a replacement for them.
If poor sleep lasts more than a few weeks, or you feel low most days, please speak to a doctor. Good help is available.
Back to 1:47 am
Three weeks later, Arjun's phone charges on the dresser across the room. His three worries sit on a notepad by the bed. He reads one page of a paperback, yawns twice, and turns off the lamp.
He does not see 1:47 am that night. He sees 6:30 am, and for once, he feels like he slept.
Your one step today: tonight, put your phone on charge outside arm's reach 30 minutes before bed, and write tomorrow's three worries on paper.
Daily Boost in you
100 mg of magnesium and 100 mg of L-theanine in one lime-flavoured daily drink, to go with your screen curfew.
