Dought & clear, - Breathing exercises to heal the chemical imbalance in the brain

I am suffering from extreme OCD and chemical imbalance. I regularly
consult with the doctor . Along with the medicine he strongly
recommended me some breathing exercises. For example inhale air from
one nostril and exhale from other and like that. It is something like
breathing exercises done by hindu saints. I wanted to know that, is it
permissible for me to do these exercises as an exercise and not relate
it with spirituality or any form of worship.
Praise be to Allah.
Firstly: interest in treating disease by means of relaxation and
breathing exercises only became common amongthe people after the
spread of neuro-linguistic programming and self-development courses.
We have previously highlighted the idolatrous foundations on which
"vital energy", "energy meridians" and "out-of-body experiences" and
so on are based.
What further strengthens the doubts and concerns about suchmatters is
what is mentioned in the question about how these practices are
usually done by some Hindu clerics or "holy men".

Secondly:
If it turns out that there is some proven medical benefit in breathing
in this manner, and that it has a clear physical effect on the body,
which doctors know from their experience and research, then thereis
nothing wrong with the sick person breathing in the mannerdescribed
and using this as a remedy, especially ifthis is a way to treat his
disease.
But if the doctor is advising that without knowing of any physical
benefits based on experience, or he does not know how this kind of
breathing affects the body or how it benefits the person who does it,
then it is not permissible, because it comes under the heading of
imitating thedisbelievers without being certain of any beneficial
effect.
Shaykh Saalih Aal ash-Shaykh (may Allah preserve him) said:
The one who describes something as a means without any scientific or
shar'i evidence and becomes attached to it iscommitting minor shirk.
There are some means that lead to results and others that do not.
If the means leads to scientifically-proven results, in the sense that
it is something that people know, then we have to see whether Islam
allows it or not.
If Islam allows it, then it is permissible to use it,.
If Islam does not allow it,but it is still proven to beeffective, such
as treating disease with haraam things, in this case we say that it is
not permissible.
The third case is that in which there is no shar'i or scientific
evidence forit. In this case, pinning one's hopes on it is a form of
minor shirk. End quote.
