Mood Shield

How your mood and energy interact, and what it means when one drops before the other.

What is Mood Shield?

Mood Shield tracks the relationship between your mood and energy over a 3-day window. It detects whether mood is leading or lagging energy, and whether they're moving together or diverging.

It's named for what it reveals about your emotional defenses. When mood holds up while energy drops, your mood is acting as a shield, buffering your system. When mood drops first, that's an early warning that your defenses are thinning.

Why it matters

In ADHD, mood and energy share the same self-regulation resource pool [1]. When that pool is being drained, mood and energy don't always drop together, and which one moves first tells you something important.

Research on emotional dysregulation in ADHD shows that mood shifts often precede energy crashes by a day or two [2]. By the time energy is visibly dropping, mood has often already started to fall. Mood Shield surfaces that asymmetry so you can act on the early signal.

The reverse is also useful. When you're coming out of a low phase, mood often rises before energy does. Catching that early is one of the most reliable indicators that recovery is starting.

How it works

Mood Shield looks at your last 3 days of mood and energy data. It compares the trend in each and categorizes the relationship into one of five states.

ValueWhat it means
ResilientEnergy is dropping, but your mood is holding up. Your mood is buffering the dip
Drain RiskMood is dropping while energy is still ok. Early warning. Energy often follows mood down
Heads UpMood and energy are both dropping at the same time. This is the highest-impact moment to slow down
LeadingMood is rising ahead of energy. Common early-recovery signal. The energy lift may follow
AlignedMood and energy are moving together normally. No asymmetry to flag

What you can do

  • When Resilient: Take it easy physically and let the mood carry you. Don't push into demanding work just because you feel good emotionally. The energy is still recovering even if the mood isn't.

  • When Drain Risk: This is your early warning. In ADHD, emotional drain often precedes an energy crash by a day or two. Reduce demands now and protect your recovery window before your body follows.

  • When Heads Up: Both dimensions are dropping. This compound pattern can make drained phases hit harder and recover slower. Rest, remove pressure, and avoid starting anything new until one of these stabilizes.

  • When Leading: Mood lifting ahead of energy is a common recovery predictor. Protect this window, don't overload it. Light work is fine, but let the energy catch up before piling on demanding tasks.

  • When Aligned: Mood and energy are tracking together. No asymmetry to act on, just business as usual.

A note on the math

Mood Shield uses a 3-day rolling window, so it reflects what's happening right now rather than longer trends. For longer mood patterns, see Mood Drift. For mood weight during drained phases specifically, see Dip Pattern.

The signal applies an honesty check on Resilient: if your mood itself is very low, "resilient" is misleading. In that case, the state falls back to Aligned (or Heads Up if energy is also low), to avoid overstating buffer strength when both sides are struggling.
