There should be no concern with your phone being 1 meter or less away from you. Even at full wattage, a phone transceiver will give off around 100mW, in most realistic scenarios it will be less than a tenth of that.
Even if you used the maximum band power of 1 watt, that isn't really enough to do anything. At rest your body will produce about 80 Watts of heat energy, which is a much higher frequency than what your phone gives off and hence has much more energy per quanta. Also keep in mind that 1 Watt is going in all directions, at best you cover half the hemisphere and even assuming phone manufacturers aren't optimizing for phones to radiate away because that gives better reception at lower power, you'd be getting half a watt of energy from a device going maximum transmit power. A standard phone will likely give you less than 5mW of energy dosage.
The most that your phone can do is warm up your ear a bit if you put it under your pillow. By an amount that is likely to be not measurable with modern equipment.
And before noting about ionizing radiation; phones aren't high enough frequency or power to really do that at any appreciable level. Only high frequencies are capable of ionizing since it requires an atom receiving a certain amount of energy per quantum, and the energy per quantum is only related to the frequency, not the transmit power.
That and does GP have a WiFi router a few meters from the bedroom, which they always unplug at night (disclaimer: I used to do that). And the clock next to the bed? Battery or socket?
You also cannot unplug all of your neighbours routers, TVs and other devices.
It is very easy to get paranoid about specific wireless technologies, it is almost impossible nowadays to avoid "electrosmog" or particularly wireless emitters entirely though.
