# TOP

> TOP (use.top) makes room-environment sensors for elite sports teams. A plug-in device with its own cellular connection measures the air (CO2, fine particulates, VOCs and NO2), temperature, humidity, light and noise in every room athletes sleep in, at home and on the road, and streams it to one dashboard for the performance staff. Teams use it to protect sleep, speed up recovery, and cut illness and soft-tissue injury on the road.

TOP is built for Directors of Performance, athletic trainers and team operations staff in leagues like the NFL, NBA, MLS, NHL, MLB and Formula 1. The device needs no app, no wifi and no installer: a kit manager plugs one in per hotel room before the team lands, and players plug one in at home. There is no camera, and the microphone reduces sound to a single decibel number on the device; audio is never recorded or transmitted.

## What we measure

Each page states the optimal range, what the condition does to a sleeping athlete, and the primary literature it is drawn from.

- [Room temperature and athlete recovery](https://www.use.top/metrics/temperature): optimal 64-72°F (18-22°C) for sleep
- [Room humidity and player availability](https://www.use.top/metrics/humidity): optimal 40-60% relative humidity
- [Bedroom CO2 and next-day performance](https://www.use.top/metrics/co2): keep under 800 ppm overnight
- [Room noise and deep sleep](https://www.use.top/metrics/noise): keep under 50 dB while they sleep
- [Light at night and athlete sleep](https://www.use.top/metrics/light): keep under 10 lux in the sleeping room
- [Bedroom air quality, PM2.5 and endurance](https://www.use.top/metrics/air-quality): keep fine particulates under 15 µg/m³
- [Bedroom VOCs and athlete recovery](https://www.use.top/metrics/voc): keep gases from paint, furniture and cleaning products near outdoor levels
- [Bedroom NO2 and athlete airways](https://www.use.top/metrics/nox): keep NO2 under the WHO 24-hour guideline of 25 µg/m³
