Why do we crave comfort as the seasons change?

The need to cosy up, slow down, and create a warm, comforting environment as we move into autumn is more than a seasonal whim. Our behaviour responds to light, temperature, routine, and learned associations with comfort, so this autumnal urge is rooted in measurable biological and neurological change.

Here’s the science bit...

The link between cooler temperatures, and safety and comfort

As summer fades and temperatures drop, our bodies naturally seek out warmth, which can trigger a pleasurable thermal response. This is the neurophysiological reward response that kicks in when your body transitions from cold to warm. It also activates thermoregulatory behaviours - the things your body does to stay at a safe temperature such as seeking warmth and shelter, and slowing down.

The result is a reduction in cortisol, a hormone that helps regulate your body’s response to stress, and increased feelings of safety and comfort.

Dr Nirusha Kumaran, a GP based in South West London, says cooler air can also change our breathing patterns.

“It naturally encourages slower, deeper breathing, and activates the vagus nerve,” she explains. “This reduces heart rate, lowers blood pressure, and puts your body into 'rest and restore' mode rather than 'fight or flight'.

“This makes autumn the ideal season for breath-based relaxation rituals. A short breathing exercise may be a simple way to build a calming pause into your day.”

The impact of light on our health and our mood

Light is the strongest external signal for your body’s ‘master clock’ (suprachiasmatic nucleus) to slow down naturally. As it runs on a roughly 24‑hour cycle and is controlled by light, autumn is a cue for a natural recalibration that encourages earlier melatonin release to make the most of the daylight, and a slower evening rhythm.

“As well as a stronger desire for quiet, low stimulus environments, these changes give us an improved ability to wind down," says Kumaran. "It’s another fantastic benefit, and another reason nesting feels intuitive and restorative.

“While some people find darker evenings conducive to winding down, others experience tiredness or a decline in mood. الاضطراب العاطفي الموسمي (SAD) is a form of depression with a recurring seasonal pattern and is different from simply preferring summer. Persistent low mood, loss of interest, marked fatigue, oversleeping, or difficulty functioning warrants medical advice.”

Warm light also supports melatonin release and evening calm by reducing blue light exposure, which can disrupt our natural rhythm and make it harder to fall asleep and maintain high-quality sleep.

Sensory stimulation is more than appearances

Autumn décor isn’t just nice to look at - it can have an impact on how we feel, too. The sensory palette of warm colours, soft textures, and natural materials we all associate with ‘cosy season’ activate oxytocin. This is connected to bonding, safety, تنظيم العواطف, and reduced anxiety.

“Warmth and softness also stimulate thermo-receptors, the tiny sensors in your skin and body that detect temperature," Kumaran explains. "These help your body move out of fight or flight mode, increasing parasympathetic activity - your body’s in-built ‘calm’ system - and reducing cortisol.

“You can activate your skin’s comfort pathways through touch by trying weighted blankets, embracing wool, fleece and knit textures, having warm baths or showers, and using heated pads or warm socks.”

How autumn scents boost your mood

We all instantly recognise those signature scents of bonfires, pinecones, and pumpkins. Studies show that scent has a direct pathway to the amygdala and hippocampus - the emotional centres of your brain.¹ Certain scents are proven to reduce anxiety and increase oxytocin.

• Vanilla, amber, sandalwood - for comfort and oxytocin.

• Cinnamon, clove, nutmeg - for warmth and grounding.

• Cedar, pine, smoke notes - for nature-linked calm.

• Lavender, sage - for parasympathetic activation, the way the nervous system calms your body and aids rest, digestion, and recovery.

Why autumn sounds feel so soothing

Notice how much more relaxed you feel when you hear the sound of logs crackling on a fire, or crisp autumn leaves being blown along a pathway? Rhythmic sounds steady our breathing and heart rate, regulating our nervous system. This was backed up by a 2025 neuroscience study led by City University in Hong Kong.²

Try crackling fire soundscapes, gentle rain, or wind ambience - ideally real but you can access recordings - slow acoustic or instrumental playlists, and low frequency ambient tones.

You can also enhance the effect by building a ‘nesting zone' - a designated space which creates a predictable safety cue for your nervous system. Try soft textures, warm lighting, a grounding scent, and a quiet activity such as journaling or reading. Just 10 to 15 minutes spent in this environment daily is an effective way to reduce stress.
