Blackout is a performance move, not a comfort one.
Evening light delays melatonin and shortens the biological night, right when a packed schedule is already squeezing sleep. TOP flags the bedrooms leaking light before lights-out.

TOP tracks light in every bedroom they sleep in, around the clock, and flags anything outside this band before lights-out.
What light does to a sleeping athlete.
Light is the brightness in the room, and in the evening and overnight it signals the brain to suppress melatonin, the hormone that prepares the body for sleep. The most pronounced effects are on the body clock and sleep. Exposure to light at night can result in delayed sleep onset, lighter and shorter sleep, a disrupted circadian rhythm, and daytime grogginess.
Evening and overnight light delays melatonin and shortens the biological night, so sleep starts late and runs shallow, right when an away schedule is already squeezing it. Blackout is a performance move, not a comfort one.
The research
Not our opinion. The literature.
100 lux
One night asleep under ordinary room light raised heart rate, lowered heart rate variability and worsened next-morning insulin resistance, against a room under 3 lux.

~25 lux
Half of melatonin is suppressed here, dimmer than normal indoor light. The most light-sensitive athletes hit that at just 6 lux.

A "dim" room is fine for one athlete and wrecking another. The band protects the whole roster.

Ordinary room light before bed already suppresses melatonin and shortens the biological night.

This limit is for sleep and the wind-down before it. Daytime is the opposite: bright light supports alertness and a healthy body clock.
You control training, load and nutrition. Control the room too.
Put a TOP device in every one of your athletes’ bedrooms at home. It runs on its own cellular connection, needs no app or wifi, and streams light and five other room conditions to one dashboard, so you fix the room before anyone sleeps in it.
Plug in and go
Connect it to power and it’s working. No app, no pairing, no setup.
No wifi needed
It brings its own cellular connection, so the player's wifi never gets in the way.
Ready in minutes
Hand one to each player. It is live the night they plug it in.
Better sleep, better recovery, fewer injuries.
Thirty minutes, your schedule. We’ll show you the dashboard live and scope a pilot for the rooms your team sleeps in next.
