Summer is often described as the happiest time of year. Longer days, lighter evenings and warmer weather can bring real benefits. But for many people, summer can also make mental health harder to manage.
Heat, disrupted sleep, body image pressures, social expectations and physical symptoms like fatigue can all add up. For people living with anxiety, depression, trauma, or other mental health conditions, these pressures can feel more intense.
This guide explains why summer can affect mental health and offers practical ways to support yourself or someone else.
Why summer can affect mental health
Warm weather can change how the body and mind feel. There are real physical and environmental factors behind this.
Heat and the body
Hot weather can lead to:
- Poor sleep or broken sleep
- Fatigue and low energy
- Headaches or dizziness
- Faster heart rate and feeling on edge
These sensations can sometimes feel similar to anxiety symptoms, which can increase worry.
Sleep disruption
Longer daylight hours and higher temperatures can affect sleep. When sleep is disrupted, it can be harder to manage emotions, stress and anxiety.
Social pressure and comparison
Summer can increase pressure to:
- Be more social
- Go out more often
- Feel happy
- Look a certain way
This can increase feelings of isolation or low mood for some people.
Physical symptoms and anxiety
Heat can cause sweating, breathlessness and a raised heart rate. These can be misread as anxiety or panic symptoms, which can increase distress.
Medication and heat
Some mental health medications can affect how the body responds to heat. This is important to be aware of, especially during warmer weather.
Some antipsychotic medications may affect how the body regulates temperature, increase sweating, or reduce awareness of overheating.
These include:
- Amisulpride
- Aripiprazole
- Clozapine
- Lurasidone
- Olanzapine
- Paliperidone
- Quetiapine
- Risperidone
- Chlorpromazine
- Flupentixol
- Haloperidol
These can also affect sweating and heat regulation:
- Amitriptyline
- Imipramine
- Doxepin
- Mianserin
- Trazodone
Some SSRIs (Selective Serotonin Reuptake Inhibitors) may also increase sweating or affect temperature tolerance:
- Sertraline
- Citalopram
- Fluoxetine
Why this matters
Some medications can:
- Increase sweating, raising the risk of dehydration
- Reduce sweating, making it harder for the body to cool down
- Affect thinking clearly or awareness of heat
- Change how the body tolerates higher temperatures
It is important to understand how your medication may affect you in hot weather. Always read and keep the information leaflet that comes with your prescription.
If you are unsure, speak to your GP, pharmacist, or mental health team.
You can also find trusted information on the NHS medication directory.
Signs you might be struggling more in summer
You might notice:
- Increased anxiety or restlessness
- Poor sleep or ongoing fatigue
- Avoiding going outside
- Feeling overwhelmed in social situations
- Low mood or irritability
- Physical symptoms such as dizziness or nausea
If this sounds familiar, it is valid to find summer difficult.
Practical ways to support yourself
Small changes can make a difference.
- Drink water regularly
- Stay in shaded or cooler spaces
- Use fans or cool showers
- Avoid alcohol during hot spells where possible
- Keep rooms as cool as possible
- Use blackout blinds or eye masks
- Maintain a regular sleep routine
- Reduce screen use before bed
- You do not need to be more social in summer
- It is okay to say no to plans
- Try not to compare yourself to others
- Focus on what feels manageable
If you feel overwhelmed:
- Slow breathing can help settle the body
- Focus on what you can see, hear and feel
- Bring attention back to the present moment
- Sitting in a park
- Short walks in cooler parts of the day
- Noticing nature in simple ways
Supporting someone else
If someone is struggling:
- Check in regularly without pressure
- Listen without trying to fix everything
- Offer practical support where you can
- Encourage them to seek professional help if needed
When to seek support
If summer is making things harder, it may help to speak to:
- A GP
- A mental health professional
- A support service or charity
You do not need to wait until things feel unmanageable.
