When temperatures rise, our physical and mental health can be affected. Understanding how hot weather can impact mental wellbeing, particularly for those living with a mental health condition, is important to help protect yourself. Periods of extreme heat may affect your mood, sleep, anxiety and simply put your overall wellbeing.

Local NHS services often see an increase in people seeking urgent mental health support during heatwaves, which is another reason why it's important to take steps to stay well, check in on friends and family, and seek help early if you're struggling.

How hot weather can affect mental health

Very hot weather can contribute to:

• difficulty sleeping or disrupted sleep
• increased anxiety, agitation or feelings of distress
• feeling irritable, frustrated or low in mood
• dehydration, which can affect concentration, energy levels and mood
• worsening symptoms of existing mental health conditions
• increased health risks for people taking certain medications, including lithium and some antipsychotic medicines

Medication and hot weather

Some medications can affect the way your body responds to heat and can make it more difficult to cope.

For example, lithium levels can become unsafe if you become dehydrated, while some antipsychotic medications can make it harder for your body to regulate its temperature. If you take these medicines, it is especially important to stay hydrated and follow any advice provided by your clinical team.

Do not stop taking prescribed medication without first speaking to a healthcare professional.

If you have concerns about how your medication may be affected by hot weather, contact your GP, pharmacist or mental health team.

Tips for protecting your mental wellbeing during a heatwave

During periods of hot weather, try to:

• drink plenty of water throughout the day, and avoid drinks containing alcohol which increases dehydration
• keep your home cool by closing curtains or blinds during the hottest part of the day
• avoid strenuous exercise or activity during peak temperatures
• take cool showers or use a damp cloth to help lower your body temperature
• maintain a regular sleep routine where you can
• talk to someone you trust if you're feeling anxious, overwhelmed or distressed
• follow guidance from your mental health team about your medication, particularly if you take lithium or medicines affected by dehydration
