The first problem you can have is - eyes problems. Spending more time in front of your computer can be harmful to your eyes.
The second - stress. Stress can cause many problems from high blood pressure to depression.
Here is my story...
This summer I went to a doctor with some health problems - I had an awful headache. Just to make picture clear - my headache was with me for 15-20 hours per day. So we did some tests showed that I had extremely high blood pressure.
“That’s odd” - I thought. I eat healthy food and I do sports.
I was confused. But the doctor said that it can happen because of stress. So I went to a psychologist to deal with this issue. We were talking about my life and interests. And I told her I trade… I believe I don’t need to continue this story lol
Since I trade a lot (I do. I could even tell this is an addiction). The doctor suggested me not to trade for about a week. That was impossible for me, but I tried. It was hard. It was more than hard. But in a couple of weeks, my headache disappeared.
I still trade but not as much as I used to. Now I practice blockchain games because it’s less stressful. Do I feel myself better? Yes. In July it was so painful so I thought that I will die. Now I don’t feel pain at all.
Conclusion:
I know it’s all individual. Some people trade days and night and they feel pretty good. I just told you my story with my experience. I don’t pursue anyone to stop trading. It’s just important for me to warn some people who can have the same problems.

Nice experience you have but I have different opinion. Not healthy because we always ignore our rules and avoid stop loss & take profit area ( greedy ). Only those things become our failure but i'm afraid many people always repeat it again. Have disciplines and believe with our skill is very important, no success with out ignore rules. I hope every one stay focus and disciplines with their rules.
