Lack of sleep could eventually lead to series of health issues and brain cells death being among them as quoting from the recent studies done by a few major international research organisations.
Looks no further, I myself am having this similar issue, only get a few hours sleep out of ordinary patterns in a day, and one of the major problems I'd always have throughout the day later is mood swinger, I tend to be hostile more easily than ever; even to the slightest problem as "low battery on my phone" could end up being a big problem to me, then my day is ruined.
I have been working out on it since so long as far I can remember, but all the ways that I could possibly think led to the dead end. Nothing seems to be effective.
Then I tried to relax by occasionally taking a weekend getaway whenever is possible, and here is to my amazement that it does seem to work and obviously costly too! But it is surely not for long till thing gets back to the square one. The unpredictable climate change - the heat - only adds up to the problem.
I even took supplements to ease my isomnia.
After consulting friends and some physicians, they came out with a rather odd but cold be true suggestion that time has come to start a family, or simply put to get married.
A suggestion that has yet to be put to test. My journey is far from the finishing line, still have a lot more to see.
If you have any better way to fight and put this to an end, why not share it with me, I'll feature that in one of my posts later?
