At this time of year, I am often asked by patients about Seasonal Affective Disorder (SAD). This is a is a type of low mood or depression that is related to changes in the seasons. It typically begins and ends at about the same times every year. Most people with SAD experience symptoms starting in the Autumn that continue into the winter months.
Symptoms of SAD may include: - Feeling depressed most of the day, nearly every day - Losing interest in activities you once enjoyed - Low energy and fatigue - Sleep disturbances (oversleeping or insomnia) - Changes in appetite or weight (often craving for foods high in carbohydrates) - Feeling sluggish or agitated - Difficulty concentrating - Feelings of hopelessness, worthlessness, or guilt In more severe cases there can also be thoughts of self-harm, death or suicide. The causes of SAD are not fully understood but are believed to be related to the reduction in sunlight in Autumn and Winter. This decrease in sunlight may disrupt the body's internal clock and lead to feelings of depression. Reduced sunlight can also cause a drop in serotonin, a brain chemical (neurotransmitter) that affects mood, and affect the balance of melatonin, which plays a role in sleep patterns and mood. Patients also ask how can SAD be treated and the symptoms of SAD improved? - Get regular exercise. Exercise can help to improve your mood and sleep. Aim for at least 30 minutes of moderate-intensity exercise most days of the week. - Eat a healthy diet. Eating healthy foods can help to boost your mood and energy levels. Aim to eat plenty of fruits, vegetables, and whole grains. - Get enough sleep. Most adults need around 7-8 hours of sleep per night. However, people with SAD may need more sleep than this. - Spend time outdoors. Even if it's cold, try to get outside for at least 30 minutes each day. Getting some sunlight can help to improve your mood and sleep. - Talk to a doctor or therapist. If you're struggling to manage your symptoms, talk to your doctor, therapist or local mental health team. They can help you to develop a treatment plan that works for you. - Self- Referral. Many parts of England allow you to refer yourself to local mental health services without requiring a referral from your doctor.
As the NHS braces for a challenging winter season, it is grappling with a "quad-demic" of health emergencies caused by influenza, Covid-19, norovirus, and respiratory syncytial virus (RSV). This confluence of viral threats poses a significant risk to public health in the UK as well as putting strain on healthcare resources, emphasising the importance of preventive measures to safeguard public health. Public health measures such a vaccination and good personal hygiene are pivotal in reducing the impact of these illnesses, particularly for vulnerable groups. The Four Viruses: What Are They? Influenza: A highly contagious respiratory infection that causes significant illness each winter. It can lead to severe complications, particularly in the elderly, young children, pregnant women, and those with chronic health conditions. Covid-19: Though its most acute phase has passed, Covid-19 remains a concern, especially as new variants of SA...
