The complexity of the human brain is unparalleled across living species. And when you take into consideration the vast number of unique variables from person to person, it can become even more abstract.
With innumerous moving parts, how do we begin to recognize the potential for a mental health condition like depression?

We hone in on the everyday functions of our body.
The good news here is that we all know them: to eat, to sleep, to move, and to connect. The bad news is that these functions can be so subconscious that we forget to reflect on them. So let’s tune in.
Your body is talking
It’s easy to connect the dots looking backward. But by understanding and identifying potential signals early on, you’ll be better equipped to manage depression and thrive while doing it effectively.
Sleep changes
When it comes to sleep, even the smallest shift can be telling. Whether you’re finding yourself buried under blankets for 12 hours or staring at the ceiling at 3 a.m., changes in sleep habits and patterns can be meaningful. If slumber is a vehicle, then sleeping too much (or not enough) is the check engine light. Get under the hood, or find someone who can.
Energy levels
A lack of motivation or sudden loss of energy are two of the most common signals that your system can send when it needs additional support. We know that motivation comes and goes, but if the things that historically filled your cup now seem draining (or if your interest has waned entirely), it’s likely outside the realm of sporadic laziness.
Major — or minimal — appetite
True or false: Depression can interfere with taste receptors. (Hint: it’s true) And when your taste receptors are disrupted, your taste perception follows suit — so you can see where this could lead some to overeating, searching for the satisfaction of the flavors and textures they once loved. On the other end of the spectrum, however, depression and other mental health challenges like stress or anxiety can cause a total loss of appetite. Whether eating too much or not enough, depression’s effect on your relationship with food is a common one.
A social shift
Finding yourself declining invites or letting messages sit unread? You’re not suddenly antisocial. Depression often makes us feel like we’re watching life happen rather than participating in it. Recognizing this pattern is actually a sign of self-awareness.
Aches and ailments
Like most other things, depression doesn’t exist solely in your mind; it can show up as headaches, muscle tension, or general physical discomfort. Your body and mind are connected— when one is struggling, the other often becomes symptomatic.
A step (or leap) forward
Whether your body has sent you one or all of these signals, know that depression is treatable and that you’re not walking this path alone. Millions of people experience depression, and many have discovered effective ways to manage it. So start small with simple tasks — setting an alarm in the morning, making your bed, or sending a single text to a friend — or go big with professional guidance or support groups. But no matter the route, this is your reminder that there is light at the end of the tunnel.
