This week there has been much written in the press about mental health, but something which is less touched on is a SAD; temporary condition which affects millions of people worldwide throughout the winter months.
SAD, or Seasonal Affective Disorder, is a condition which can have a profound effect on mood, and mental health from late autumn until the spring. Symptoms can include tearfulness, stress and anxiety, lack of concentration, irritability, feelings of low-esteem and worthlessness and general despair, and in severe cases sufferers can feel suicidal. A lack of sleep can often be a major issue, and it can also influence appetite, immunity and production of feel good hormones such as serotonin, which help us feel positive and motivated.
The main cause is the lack of sunlight, which causes the brain to produce more melatonin; a hormone which helps us sleep at night. Melatonin production is triggered by the brain as darkness sets in, and then cortisol is produced as daylight emerges to help us feel awake and active, so longer darker days can cause hormone imbalance which can impact on many facets of our well being. This hormone shift can encourage comfort eating and binging, blood sugar imbalance leading to mood swings, and weight gain. Another side effect can be an impaired immune system, which can explain why we are so susceptible to colds and flu at this time of year.
So what can you do to beat the winter blues?
Finally, comfort eating is fine if you choose the right options. One pot dishes such as bean and vegetable stews, shepherds pies, fish pies, or curries will give you nutritious filling meals to keep you going until the days start getting much longer!
So, if your friends, family or colleagues are grumpy and irritable this winter, a good place to start is with their diet. After all, as Paul Theroux once wrote “Winter is a season of recovery and preparation.”
A study reported in HR Magazine recently suggested that the average employee now has 7.7 days absence, costing £673 each per annum.. Two thirds of those days occurred across the winter cold and flu season and this can have a major negative impact on any workforce, but small businesses in particular.
Now that the coughs and sneezes are starting to circulate, what can you do to prepare yourself, your business and your colleagues, and try and avoid becoming part of these statistics?
Hygiene in the workplace is a key issue with a significant number of germs being spread around office equipment and in places like communal kitchens. The close proximity of workers, and the unavoidable commute to work for many, is also problematic.
Whilst coming into contact with the germs may be unavoidable, a poor diet is one of the immune system’s greatest enemies, so the best preparation you can have is to build your immunity ready to fight off the germs, and eating the right foods can help significantly. Once the immune system has started to break down, it has to fight harder to fend off the bugs and is more likely to succumb repeatedly over the winter leaving you vulnerable to every germ circulating.
In an earlier blog I talked about specific nutrients which can help build the immune system naturally. Here are some tips to making small but important changes:
WHAT TO DO WHEN THE GERMS STRIKE
COMFORT EATING
The temptation on long cold winter days is to resort to comfort eating, but by combining many of these immune boosting foods you can create tasty and filling family meals which are packed with nutrients and can help you fight the germs.
Chicken soup traditionally fits the bill here, so experiment with using leftovers from your Sunday roast to best effect, or turn leftover vegetables into soups and broths. Also consider making one pot meals such as Chilli con Carne, vegetable or meat stews and curries which you can freeze and have available as healthy alternatives to shop-bought ready meals or takeaways. Fill them with vegetables, peppers, mushrooms, peppers, garlic, onions and beans for optimum nutritional value. As a side dish try making spice rice adding lime zest, sliced chilli pepper and garlic.
….. And don’t forget to start your day with a warming bowl of porridge; add grated cinnamon and a handful of defrosted berries for the perfect winter breakfast.

“The doctor of the future will no longer treat the human frame with drugs, but rather will cure and prevent disease with nutrition.”
A wise prediction from Thomas Edison at the turn of the 20th Century, but maybe one we have lost sight of.
Modern medicines focus on destroying the invader once it has attacked, but surely a better approach is to build our immunity naturally to fight the bugs off before they take hold?
So how does our immune system work?
The thymus gland, located in our chest in front of our heart, produces T-lymphocytes or T-cells, which are a critical feature of our immune system. These immune cells create and mobilise a defence army within us which then identifies the foreign invaders and attempts to destroy them. The thymus gland relies on a number of nutrients:
Vitamin C, sometimes referred to as the ‘master’ immune nutrient, is thought to nourish the thymus gland, in doing so helping immune cells develop and increasing our white blood cell count. It also has both anti viral and antibacterial properties and can act as a natural anti-histamine and anti-inflammatory.
Zinc also supports the thymus gland and helps increase white blood cell count, increasing the defence army and so reducing the duration of an infection.
Vitamin A supports the mucous linings found in the nose, throat, lungs and digestive tract, and can therefore help prevent viruses from taking hold. (Note: Pregnant women should beware Vitamin A rich foods since high levels in the diet can harm the foetus.)
Herbal remedies can also be incredibly powerful for both boosting the immune system and fighting infection
Echinacea has anti viral properties which stimulates production of immune cells. Trials published in The Lancet in 2007 indicated that those taking Echinacea were 35% less likely to get a cold when directly in contact with rhinovirus than those not taking the supplement. It also reduced duration of colds by 1.5 days. Trial participants saw greatest effectiveness when taken Echinacea alongside Vitamin C (reducing infection by 86%)
Golden Seal has antibiotic properties; Garlic and Calendula are both antiviral and anti bacterial.
Tea Tree oil works against staphylococcus, the bacteria responsible for infections ranging from a simple boil to MRSA which is now resisting conventional antibiotic treatments; hence the rise in popularity of Tea Tree hand washes and wipes.
The importance of probiotics:
With an increase in virulent infections such as the Norovirus vomiting bug over the winter, it is particularly important to try and improve the balance of good versus bad bacteria in the gut. Our gut provides a home to billions of bacteria , and the ‘good guys’ form a large part of our immune defence system; particularly from pathogens ingested through food. ‘Friendly’ or good bacteria, such as Lactobacillus, L-Bulgaris and Bifidobacteria are key to helping us fight infection, acting as nature’s antibiotic by consuming the nutrients that can feed and encourage ‘bad’ bacteria. They also proliferate to fill the receptor sites that harmful bacteria need to replicate infection.
Sugar is an important food source for all forms of bacteria, so best to avoid a sugar rich diet (white bread and pasta, refined carbohydrates, sweets and cakes, and sugary yoghurts) and instead include prebiotic foods (also known as Fructooligosacchaides or FOS) in your diet which will specifically help feed the good guys. Foods rich in prebiotics include chicory, Jerusalem artichokes, onions, garlic, leeks, bananas, legumes and whole grains.
TOP TIPS TO SUPPORT YOUR IMMUNE SYSTEM
A diet rich in a variety of fruit and vegetables, whole grains and essential fats (oily fish, nuts and seeds) should give you a good supply of all these vital nutrients, but avoid too many processed foods and sugary foods. Go wild with the herbs and spices; a win-win since they are not only nutrient-rich but also to add flavour and interest to your cooking.
Good quality sleep is also vital for your immunity since much of our repair and rebuilding takes place whilst we are asleep, so try to ensure you get a good night’s rest as often as possible.
Drinking plenty of water will also not only help flush toxins through, but is required for every chemical reaction in our cells, so water is also an important immune support. Aim to drink around 2 litres or 6 large glasses a day, and for an extra immune boost, start your day with a glass of hot water with a squeeze of lemon or lime.
If you are inspired by today’s Great North Run to get out and start your training for the Brighton Marathon and Brighton Half Marathon, don’t forget to pay as much attention to your nutrition as to your running.
Starting any new exercise regime over the winter can leave you prone to injury and deplete your immune system, making you more susceptible to winter bugs, so you don’t only need concentrate on eating for energy, but also for immunity and repair.
