Meditation will give you peace of mind and ability to control the negative thoughts, it provides control on subconscious mind with practice and much more.
Moolbandha-improves your ability to retain vital energy and helps to check nightfall
Jalandharbandha-improves pranic energy, good for thyroid and stamina
Uddiyanabandha- transmute vital energy towards sahastar chakra, flow of vital energy upwards
Mahabandha- when you do above three simultaneously
Mahamudra- similar to Moolbandha
Surya namaskar - overall fitness of whole body, combines several yogasanas so good
Shirsasana- blood flows towards brain so more oxygen to it. Good for improving mental capacity, health of hairs and teeth etc.
I would highly recommend you to practice them and experience the benefit yourself. (Many benefits maybe subjective depends on other variables like lifestyle habits, thought process etc. Good thing is there is no side effects😊)
In my opinion the crux is to engage and excercise body, brain and intellect…
So you should try it for sure.
Peace
