Change it to warm light or turn on blue light filter on new equipments.

Blue light excite cortisol, suppress melatonin.
We need cortisol to wake up from sleep, melatonin to fall asleep.

9pm, we need melatonin. 4am we need cortisol.

Too much cortisol and too less melatonin can degrade our immune system.
