Five ways to help ‘fight or flight' stress hormone and bring down blood pressure
Triggering the body's natural stress hormone is perfectly normal when it's needed – but if it stays high it can lead to weight gain, or too low, it might cause fatigue and low mood
The internet is awash with tips, tricks and hacks to fix minor medical problems. But how much of it is accurate and can be trusted? In an age of misinformation and social media 'experts', it is always better to ask someone who is in the know about your health woes.
Each week, Superintendent Pharmacist Claire Nevinson will answer our readers' questions on everything from insomnia and indigestion to trapped wind and toilet troubles. This week, Claire tackles the stress hormone, cortisol…
Q. Everyone is talking about high cortisol on social media – is it actually a problem that a lot of people have, or has it been blown out or proportion? What are the actual symptoms and what should we be doing about it?
Cortisol is the body's natural steroid, also known as the body's stress hormone. It plays a key role in managing many bodily functions including regulating blood sugar levels, helping the body cope with and respond to stress, controlling blood pressure, regulating metabolism and immune function and reducing inflammation.
What leads to high cortisol levels?
During times of stress, the adrenal glands of the body will release both adrenaline and cortisol. This can lead to increased energy levels, which is the body's way of preparing for what it perceives as a potentially harmful or dangerous situation.
Spikes in these hormones should naturally return to normal levels when the situation that triggered them is over, but during extended periods of everyday stress this doesn't always happen and cortisol levels may remain high. This can increase the risk of many health conditions including weight gain, anxiety, heart problems and high blood sugar.
In rare cases, higher than normal cortisol levels may also be a result of Cushing's syndrome. This is an uncommon condition with the main symptoms being weight gain, typically on the chest, stomach, shoulders and back of the neck, as well as a red, puffy and rounded face. If you are concerned about any symptoms, you may be experiencing, you should speak to your GP.
What leads to low cortisol levels?
While the issue of high cortisol levels has seen a lot of attention, particularly on social media, the body can also experience low cortisol levels.
This occurs when the adrenal glands don't produce enough cortisol. This is known as Addison's disease – a rare condition, which usually occurs because of a problem with the immune system. It can cause lack of energy, fatigue, muscle weakness, low mood, loss of appetite, dizziness, losing weight without trying and increased thirst.
How can we manage cortisol levels?
Reduce everyday stress
If the changes in cortisol levels are caused by prolonged everyday stress, it's important to try and identify the triggers if you can. This is a good first step towards finding coping mechanisms and ways to avoid stress.
Eat a balanced diet
A healthy and balanced diet can help support your physical health and emotional wellness. Try to eat a nutrient-rich diet full of fruits and vegetables, whole grains and healthy fats as well as drinking plenty of water. Try to limit your caffeine intake and the number of foods you consume that are high in added sugar and saturated fats.
Undertake regular exercise
The NHS recommends 150 minutes of moderate intensity activity or 75 minutes of vigorous intensity activity a week, which can help reduce feelings of stress and therefore can help manage cortisol levels. Make sure to speak to your GP before starting any new forms of exercise if you have an existing medical condition or have not exercised in a while.
Get plenty of sleep
Aim for seven to nine hours of uninterrupted sleep a night to reduce everyday stress and manage cortisol levels. It can help to establish a sleep routine and going to bed and getting up at consistent times.
You should also try to reduce screen time or eliminate it altogether before bedtime and replacing for anything that helps your body and mind to relax instead. This could include a warm bath, face mask or reading a book.
If you're experiencing symptoms that make you think your cortisol levels may be imbalanced, make an appointment to speak to your GP.

Ask the head gardener: How often should I water my pots?
Dear Tom, I have moved from a half-acre garden to a south-facing terrace. I had never used pots in my previous garden, so now I'm not sure how often and how much to water. I have several huge pots, and some medium ones so far. – Claire, West Sussex Dear Claire, Container gardening is periodically intense but can provide the most amazing riot of colour and seasonal interest, making a small space work very hard in terms of impact. The way in which you water and feed your containers will make the difference between a reasonable display and a spectacular one. One of the features of peat-free compost is that the surface can appear to be dry but, quite often, a little further down into the root ball, the compost is holding much more moisture. Given that watering and feeding have a great impact, here is my guide to tending your containers. Drainage Healthy plants grow in compost with a more open structure and better air circulation because roots need that gas exchange in the same way as every other part of the plant. A saturated compost will significantly reduce the amount of gas exchange that occurs within the compost and then will compromise plant growth through root rot. For small trees or shrubs in containers, I would recommend mixing in 25 per cent of horticultural grit to open that structure within the compost and improve drainage. Containers can dry out readily during the summer but it's also worth considering what happens to your pots during the winter. Saturated, frozen compost will expand and can cause terracotta pots to crack. Raise your pots on pot feet to allow any surplus moisture to drain away, especially during the winter months. For extra protection and insulation, your containers can be wrapped with bubble wrap to offer them a few degrees of extra warmth during prolonged cold spells. Top dressing Mulching your containers with gravel or composted bark will not only look great, but will also help to suppress weeds that will compete for moisture, and will help to lock in moisture in the compost. A layer of a few centimetres will suffice. Active growing season Many of our garden plants will have an active growing season from around the end of March until the end of October. This isn't set in stone and is in response to increasing light levels and temperatures. When plants are growing rapidly, they need more moisture and nutrition to sustain healthy growth. Water your containers more frequently during this time, with a daily watering during the months of June, July and August. As the plants become more dormant and slow down, their need for water is drastically reduced, along with the need for fertiliser. It is much better to keep your containers slightly on the drier side during this dormant period to maximise that gas exchange within the root ball. The addition of a liquid feed once a week for your containers during the active growing season will help produce great results. Initial growth should be encouraged by a weekly feed of seaweed fertiliser, followed by the application of a tomato feed once a week when the flowers appear. Watering Watering is best carried out first thing in the morning when plants are waking up. During the evening and at night, plants are not processing water, so although the compost may be saturated, plants won't use that moisture until the sun comes up. Try to avoid watering your plants little and often as this will encourage surface rooting, and in times of stress through drought, your plants won't have the resilience that they would if you encourage deeper rooting by saturating the compost to the bottom of the pot. For bedding plants and hanging baskets, your finger is a good indicator to see how much moisture lies beneath the surface. If you detect moisture on your fingertip then there's no great need to water, especially during the early spring, autumn and winter.

Early warning signs of strokes in dogs to look for as vet says it's 'pretty common'
Early warning signs of strokes in dogs to look for as vet says it's 'pretty common' A vet has detailed the 'early warning signs and symptoms to look out for' which signal your pet dog or cat could be having a stroke, as the condition becomes more 'common' among animals There's several symptoms dogs may present which are indicative of a stroke (stock image) (Image: undefined via Getty Images ) Many households around the world cherish the companionship of a pet dog, with their seemingly endless affection and steadfast loyalty making them an integral part of the family. Opting to have a dog is not a decision to be taken lightly; it calls for a profound shift in lifestyle as these animals demand regular love, care, and attention. This includes frequent veterinary visits for health checks and ensuring they get their daily dose of exercise. In the UK alone, there's a staggering estimated number of 10.6 million pet dogs, with owners keen to ensure their canine companions maintain good health. The proliferation of social media has become a boon to those looking to optimise their dogs' wellbeing, as a myriad of videos from passionate pet owners and professionals alike offer advice and knowledge. Being vigilant about recognising early signs of serious health issues can have a significant impact on your dog's wellbeing. A particularly impactful video that's garnered attention on social media features specialists detailing "early warning signs and symptoms to look out for" that might suggest a dog or cat is suffering a stroke. Board-certified veterinary neurologist Dr Sheena Sanil from SEVN commented: "It turns out that strokes are pretty common in our small animal friends, so it's important to recognise the signs. Article continues below "Strokes occur suddenly without any warning signs and they should not be painful but can cause an abrupt and severe onset of symptoms." Dr Sanil elaborated on the symptoms linked to a stroke within the forebrain of pets, including behaviours such as circling, as well as seizures, dramatic changes in behaviour, head pressing, and even blindness. The vet outlined that symptoms of a stroke in the brain stem or cerebellum can include "poor balance, vomiting, nystagmus - or abnormal eye movements - weakness on one side of the body, high stepping, head tremors, severe mentation changes or changes in consciousness, acute circling or spinning." Dr Sanil said: "Just like in people, strokes in pets occur either when the blood flow to part of the brain is obstructed, which is known as an ischemic stroke, or when a blood vessel bursts and deprives nerve cells of oxygen, which is a hemorrhagic stroke. "Strokes generally occur in older pets and are often secondary to a chronic metabolic disorder. Cases of an ischemic stroke are often secondary to hypothyroidism, renal disease, Cushing's disease, neoplasia or cardiac disease. "While cases of hemorrhagic strokes are often secondary to clotting disorders, metastatic cancer and toxins. However, about 50% of strokes in dogs have no identifiable underlying cause." The vet further noted: "It is also worth noting that some dog breeds are much more prone to strokes, such as the greyhounds and mini schnauzers." In the caption accompanying the video, the expert advised: "If you suspect your dog or cat may be affected, early diagnosis and treatment are essential. Contact a veterinary neurologist to discuss the best path forward for your pet." It's crucial to remember that both novices and professionals who share their personal experiences or expert advice on social media can only provide a generalised perspective. They don't know you or your pet personally. If you have any worries about your pet, it's advisable to take them to your vet promptly for a personalised consultation and bespoke treatment plan. If you're contemplating getting a dog, it's vital to do your homework first. Training is fundamental with puppies and dogs, and not all dogs are suitable for first-time owners. Article continues below If you're planning to bring a pet into your home, consider the advantages of adopting a puppy or older dog from a charity or local shelter instead of purchasing from a breeder.
