Winter and Your Mental Health: What's Normal and When to Reach Out

Winter can do a number on how you feel. The days are shorter, it is cold, you are spending more time indoors, and the things that usually lift your mood — exercise, socialising, time outside — can feel harder to get to.

For a lot of people, this is just the seasonal background noise of June, July, and August. For others, it tips into something that genuinely affects daily life. Knowing the difference is useful.

What is common in winter

Feeling a bit flat, sleeping longer, having less motivation, and wanting to eat more comfort food are all things that tend to increase in winter. These are common and do not automatically mean something is wrong. They can often be managed by keeping up with exercise (even short walks count), maintaining social contact, getting outside during daylight hours where possible, and keeping a consistent sleep routine.

It is also worth being mindful of alcohol intake during winter. Drinking more as a way to manage low mood or stress is a pattern that tends to make things harder over time, even if it feels like relief in the short term. If you are taking part in Dry July this year, you might find it useful to notice how your mood tracks through the month without alcohol in the mix.

When it is worth talking to someone

Some signs that what you are experiencing goes beyond the usual winter dip:

• Low mood that does not lift, even on good days
• Losing interest in things you normally enjoy
• Significant changes in sleep, not just sleeping in more
• Withdrawing from people you would normally want to see
• Feeling hopeless or finding it hard to see things improving
• Changes in appetite that feel out of your control
• Difficulty concentrating or making decisions
• Thoughts of self-harm or suicide

You do not need to be in crisis to see a GP about how you are feeling. You do not need to have a specific label or diagnosis in mind. A general conversation about what you have noticed is a perfectly valid reason to book an appointment.

What a GP can do

Your GP is often the first and most practical point of contact for mental health support. They can help you make sense of what you are experiencing, rule out physical causes (low iron, vitamin D deficiency, or thyroid issues can all affect mood significantly), and work through the options with you.

If a referral makes sense, your GP can put together a Mental Health Treatment Plan under Medicare, which subsidises a set number of sessions with a psychologist each calendar year. This is a practical step that many people do not know is available to them through a standard GP appointment.

Your GP can also discuss other options depending on what is going on, including talking through lifestyle strategies, considering medication if that is appropriate, or referring to a psychiatrist or community mental health service for more complex needs. The point is that a GP appointment is a starting point, not a last resort.

A note on vitamin D in winter

It is worth mentioning because it comes up often. Vitamin D levels tend to drop in winter, particularly for people who spend most of their time indoors. Low vitamin D has been associated with low mood and fatigue, though it is not the only explanation and it is not a substitute for proper mental health support. If you have not had your levels checked recently, it is something your GP can include in a blood test.

Looking after yourself day to day

While professional support matters when things are genuinely difficult, there are also small daily habits that help maintain mood across the winter months. Getting outside for even 20 minutes during daylight hours supports both mood and vitamin D. Keeping up with social connection, even when it feels like effort, tends to be protective. Regular movement does not need to be intense — a consistent daily walk is enough to make a difference for most people.

If you are struggling to manage any of these things, that is useful information in itself, and worth mentioning to your GP.
