Understanding Seasonal Mood Changes in Senior Loved Ones

Many families notice a shift in a parent sometime between October and February. She naps more, calls less, and seems flat during conversations that used to spark. Even in Southern California, shorter days and changing routines can affect how people feel. Seasonal Mood Changes may be mild and temporary, but a noticeable change in sleep, energy, or interest in everyday activities deserves attention. Senior Helpers looks at what families can watch for and when it may be time to involve a doctor.

Why Seasons Can Affect Mood

Less daylight can affect sleep and energy. The National Institute of Mental Health explains seasonal affective disorder, a type of depression tied to the change of seasons, and describes how professionals diagnose and treat it. Plenty of people just feel slower in winter.

Routines shift in winter too. Holiday gatherings come and go, grandkids head back to school, and outdoor time in Chino Hills or Corona may drop as evenings cool and the patio chairs go unused.

Seasonal mood changes do not automatically mean someone has SAD. Holiday schedules, fewer outings, changes in family routines, grief, health concerns, or spending more time indoors can also affect how an older adult feels.

Changes to Keep an Eye On

Look for changes that continue rather than judging one quiet afternoon. Signs worth noticing include:

  • Sleeping much more or less than usual
  • Changes in appetite
  • Losing interest in favorite activities
  • Pulling away from friends or family
  • Low energy or unusual fatigue
  • Irritability or restlessness
  • Difficulty concentrating
  • Feelings of hopelessness

Depression is not a normal part of aging, and older adults may show symptoms such as loss of interest, low energy, changes in sleep or appetite, or social withdrawal rather than obvious sadness.

If several symptoms last more than two weeks or begin interfering with daily life, encourage your parent to speak with a healthcare provider. The National Institute on Aging has information on depression in older adults, including when to seek help. Medical conditions and medications can sometimes cause similar symptoms, so a professional evaluation matters. If your parent talks about suicide or self-harm, call or text 988 right away.

Seasonal Mood Changes and Staying Connected

Social contact cannot replace treatment for depression, but regular connection can keep long stretches of isolation from becoming the default.

Try putting a few dependable points of contact on the calendar:

  • A weekly lunch or coffee visit
  • Sunday services or another familiar community activity
  • A short walk with a neighbor
  • A standing phone call with a sibling or cousin
  • A quick video chat with grandchildren

Keep the commitment realistic. A five-minute call that happens every Tuesday may be more useful than an elaborate outing that keeps getting postponed.

Small Daily Routines

Keep wake-up times and bedtimes fairly consistent from one day to the next, including weekends, because a parent who sleeps until ten on Saturday often has a harder time settling down on Sunday night and ends up tired and out of sorts on Monday. Get outside around midday. Opening the blinds each morning and sitting by a sunny window together over coffee is an easy habit to start.

Ask your parent what used to cheer them up in winter, and try bringing some of it back. Some families make tamales together in December. For others, it's a jigsaw puzzle that stays out on the dining table all season, with everyone who stops by adding a few pieces and staying for a chat.

Seasonal mood changes can be easier to notice when the usual routine stays relatively steady, because families have a clearer sense of what is actually different.
