Mercury in the 1st House: 5 Ways it Can Affect You

Mercury in the 1st House

When Mercury is in your 1st House, your mind and intellect are one of the most important parts of your life. You are observant and thoughtful. You rely on your intellect and rationality when making any important life decisions.

To understand what it means when a planet lands in a house on your natal chart, you need to look at the meaning of the house, meaning of the planet, and how they interact:

  • The 1st House represents the identity, your approach to life and how you handle big life changes, how you make big life decisions.
  • Mercury is the planet of communication, expression and mindset.
  • When Mercury is in the 1st House, it means that you are an intellectual person who relies on their mind rather than their heart. You are curious and you always seek to find out more about everything. People view you as someone intelligent, someone you can seek advice from.

Note that this is just one facet of your natal chart. Other elements of your natal chart can overpower or contradict with the below points. To get an accurate reading, get a holistic reading of your full natal chart from an astrologer.
