Home
The rooms you spend most of your life in. Air, water, the bedroom and the way a room is arranged are the parts of your environment you can actually check and change.

Where the sun comes in, and where it doesn’t
Some of the sun reaches your home directly: daylight comes in through the windows, and the bedroom is where night, light and Earth’s magnetic field meet your sleep. Air and water are here for a simpler reason. They are measurable, they change what your home feels like, and readers asked about them.
