When our energy body expands, it picks up the energies which are around us. We start reacting differently to things which were always the same, simply because we now grasp their energy more easily.
Energising of the kundalini brings increased empathy, increased awareness/perception and intuition, coupled with the expansion of the energy body. That is what causes you to pick things up and also be affected by it. It’s a good thing, it’s a spiritual progress, but you have to learn to balance it out.
Simple things like daily meditation or chanting, or reading a kavach of a deity, or adding a handful of rock salt to your bathing water every 3-4 days will help cleanse your energies, daily morning exercises, etc.
Fundamentally, what you would do is – 1, something to protect your energies; 2, something to prevent outside energies from disturbing you (you will still sense them, just not be disturbed); 3, move on your spiritual path as per your calling.
Best way to achieve it is with meditation etc. However until that happens, few things mentioned above will help. Also can use some crystals like clear quartz etc. Even wearing a rudraksh helps in the same.

What I’m trying to say is that the cause of this is a spiritual growth which happened, and now you have to adjust with it for which 3 things would be done. There are soooo many ways of doing that, so you can pick what you like the most and may be even switch between them.
This is a phase on the path and will pass away 🙂

Astrological remedies are not really needed because there is no problem, just a new blessing.
