Mood & Mental Health
Anxiety
Persistent worry, nervousness, or physiological arousal — racing heart, shallow breathing, muscle tension — that interferes with daily functioning. Can be triggered or worsened by stimulants, hormonal changes, and overtraining.
Depression / Low Mood
Persistent feelings of sadness, hopelessness, low motivation, or anhedonia. While clinical depression requires professional care, many health practices have meaningful evidence for mood improvement.
Irritability
Increased emotional reactivity, short temper, or low frustration tolerance — often a sign of hormonal imbalance, sleep deprivation, blood sugar dysregulation, or overtraining.
Mood Swings
Rapid or unpredictable changes in emotional state — highs and lows within the same day — frequently linked to blood sugar instability, hormonal fluctuations, or stimulant cycles.
