how do i increase my reaction time!

Basically, you improve just by playing, but if you want to speed things up a bit, you can use Human Benchmark and do KovaaK's exercises like Gridshot or Piano Tiles. If you play Valorant, there's a site called Oki Aim—it's pretty good for a web-based tool. If you play CS or Fortnite, you can use in-game maps. Anyway, this is just what worked for me; it might not result in a massive improvement, but I hope this helps! :D

Reaction time is a difficult thing to improve because there are several different things that people call "reaction time." Your raw physiological reaction speed is relatively constrained, while perception, anticipation, decision-making, and motor execution are much more trainable. With 195ms going to maybe 170-150ms should be possible though IMO.

Sleep, fatigue, general health, stimulants such as caffeine, and your hardware/setup can affect measured performance. You can improve Reaction Time somewhat through practice, just don't expect huge changes. Reflex Flick - Fair - Precise or other reflex flick scenarios are good for that (Im not a pro so mby there are better ways, I can only say what I know).

You can get better at recognizing things though. This is huge in games. An experienced player doesn't necessarily have a dramatically faster reaction time, but often detects relevant information faster because they know what to look for. Becoming good at Target Reading will also help a lot.

Also check out the video Viscose made about this (https://www.youtube.com/watch?v=OJcE6lRTipM), I think its really well explained & might help you!

its hard to sort of train for this, the easiest way to improve it by some degree is to get a high hz monitor

isn't the correct wording here decrease as you want a lower reaction time?
