but I read that as genuine concern, as you didn't know why I didn't sleep much.
Trying to get more sleep today, but either people keep me from sleeping (being loud outside, being my boss and thinking I need to work) or my organism decides to pump out cortisol or adrenaline and that keeps me awake.
Oh damn I’m sorry to hear about that, hoping things get better for you
idk if this helps but when there’s too much noise outside or too much stress inside I like to put on the radio quietly to drown it out, there’s something about being tuned into static-laden local broadcasts that makes me feel less lonely and more connected, not caught in the crazy buzz of the global internet but also not wallowing away by myself. It’s very comforting for me.
For the adrenaline aspects... I had insomnia for years from anxiety+ issues. I know it might sound silly, but doing breathing exercises helped me calm my heart rate down to have a better chance to fall asleep.
I do a version of the 4-7-8 Breathing Exercise at this site: https://www.verywellmind.com/abdominal-breathing-2584115 (I do more of a 4-5-5 and don't bother with tongue placement. Just alternating nose/mouth breathing and holding breath in between.) It was recommended to me by a therapist and it helped my issues. I haven't tried the other exercises on there though.
I’m in the same boat. A traumatic event happened to my husband and it’s got me so shaken up that I wake up at odd hours of the night with my heart pumping.
Seeing your stats, I'd start with always getting up at the same time. Going to bed at the same time is harder, when you always get up at the same time your body might feel sleepy in the evening.
Some other ideas:
Try to reduce light in the evening and use screen filter like Redshift or the one included in KDE or Windows.
Try to go outside more, preferrably directly after you stood up in the morning.
Reduce the temperature of your sleeping room
Use a weighted blanket
if you don't have the money for one, you can simply put any weights on your blankets so you move less and feel the pressure
drink less alcohol and sweetened drinks
consume less carbohydrates and more protein
drink more water throughout the day, at least approx. 0.4L/10kg body weight (so for a 75kg person, drink at least 3L)
I will try to keep your tips in mind. Drinking more and going more outside is definitely something I should do. Also maybe I will install curtains to make my room darker. The weird thing is I don't really feel tired not sure if I trust the stats from my phone but the screen on time seems pretty convincing that something is wrong. I almost drink zero alcohol and I eat healthy. Maybe I need to take melatonin spray again it really helped me in the past.
