Would this be due to lack of light in the morning when waking up?

If so, that's a solved problem these days. There's hundreds of ways to have lights that turn on in the morning. Having some kind of wakeup-light (simply two bright Philips Hue bulbs in the bedroom ceiling lamps these days) and taking vitamin D has solved the issues I've had with living far north, where it's dark most hours in the morning in mid-winter.

Most of us solve it by flooding our face with phone light in the middle of the night ;)

You can say the same thing about lack of light at night?
