Why do paranormal researchers seem to only investigate at night?

There are actually several reasons for investigating in the dark.

Human’s other senses are heightened when sight is diminished.
Less people are out and about at night.
Many paranormal investigators have day jobs, too.
Certain paranormal events may occur habitually at a certain time of day.
Honestly, it does increase the thrill of doing the live investigations in these locations.

Humans’ other senses are heightened when sight is diminished.

This is a scientific fact. Our eyes do adjust somewhat to low-light situations, but our hearing, sense of smell, and all other sensory devices at our disposal become more in-tune with our immediate surroundings. A seasoned investigator will recognize this, and will work diligently to debunk any strange happenings that occur without immediately writing them off as paranormal.

Less people are out and about at night.

This is important because this means less noise pollution from the surrounding population. When a haunted location resides in the middle of a downtown location that is bustling during normal work hours, but calm and quiet at night, you would definitely choose the latter time to investigate it. It makes the whole situation much easier to decipher the paranormal from the explainable.

Many paranormal investigators have day jobs, too.

Sadly, this is just the reality. Investigating the paranormal would ideally be my full-time job, but for many in this passionate community, it is only a fun hobby. Thus, we work during the day and, when we have time, we investigate at night!

Certain paranormal events may occur habitually at a certain time of day.

This is true at night as well. Residual haunts may involve an event, such as a murder or accidental death, that occurred at a specific time of day. These events replay over and over, at or near the same exact time every day (or night), and could be the reason for a team of researchers to choose to visit a location at that time.

Honestly, it does increase the thrill of doing the live investigations in these locations.

As lovers of the spiritual realm, many of us do also enjoy a good scare every now and then. It’s one thing to watch a scary movie about ghosts in the dark, but it’s another altogether to live through a paranormal experience! The thrill of prowling around in the dark and happening upon these experiences is second to none.
