· If you suffer from regular itching or rashes, medical advice may be needed.

Get the jump on dryness this winter with a few simple routine changes that will replenish your body, inside and out.

Biohacking is a do-it-yourself approach to biology that’s designed to optimise your body for better health and wellbeing outcomes. While it might sound a little intense, biohacking often begins with a simple blood test to ascertain if, and in what ways, the body may be deficient.

From there, a health professional can recommend a course of action – via supplementation or complementary therapies – to bring the body back into balance.

The high-tech technique relates to our internal health – gut, liver, kidneys – but can also apply to the body’s largest organ: the skin. Adjustments may need to change seasonally as our bodies live in a state of flux based on our environment, and given how harsh winter can be, now is a good time to make some well-informed tweaks.

In fact, recent research commissioned by skincare brand Cetaphil found that eight million Australians feel they look older simply because winter has rolled around. The main complaints were dullness, dehydration, dry flaky skin, cracking skin and looking paler. Dr Yalda Jamali, a specialist in facial aesthetics and cosmetic dermatology, says taking stock of your skincare routine and wellbeing as the mercury plummets can help to see you through the season.

Hack it from the inside

Top up your vitamin D

“I always advise getting regular blood tests at your GP to check for deficiencies,” Jamali tells Body+Soul, adding that she doesn’t like to prescribe supplements unless there’s a deficiency. “However, the one supplement that I do recommend is vitamin D. Our bodies produce vitamin D when sunlight (specifically UVB rays) hits our skin, and in winter, we usually get less sun exposure.” She says this essential nutrient can also be sourced naturally through the winter sun (being sun safe, of course), and from your diet (through eggs, liver, fatty fish and beef).

Overhaul your sleep routine

“Studies have shown that chronic poor sleep quality is associated with increased signs of intrinsic ageing and poor skin barrier function,” says Jamali. “Good- quality sleep will allow your skin to recover more efficiently from UV-induced damage. I also recommend using a silk pillow, which helps to prevent sleep lines forming, and also keeps your skin better hydrated as they don’t absorb as much moisture as cotton pillow cases.”

Don’t skimp on self-care

“If you’re feeling run-down or struggling with your [overall sense of] wellbeing, this can have a knock-on effect on your sleep, diet, exercise, relationships and all of your activities of daily living,” explains Dr Deshan Sebaratnam, a dermatologist and senior lecturer at the University of Sydney. “All of these things can contribute to skin disease,” he tells Body+Soul.

“Sometimes, when other facets of your life become difficult, you might not have the bandwidth for self-care activities [such as] taking your medications or attending medical appointments.” So don’t skimp on your self-care this winter, and be sure to speak to someone if you’re struggling. Tech can also assist with the winter blues, including sun lamps, which are designed to mimic the rhythm of the summer sun, to regulate melatonin and release serotonin.

Hack it from the outside

Boost your barrier

Dermatologist Dr Leona Yip says barrier and protective products are essential in winter to trap and lock in moisture.

In the shower

Winter is a good time to re-think your showering habits. Jamali suggests a few simple changes, such as not showering in extremely hot water, and not excessively drying your skin afterwards but instead aiming for gentle taps with your towel.

She suggests opting for calming and pH-balanced cleansers and avoiding overuse of products with acids such as AHAs or BHAs. If you suffer from dry skin already, use emollient substitutes for your shower wash.

On the hair

Sydney hairstylist Anthony Nader, owner of online retailer SSS Hair, says adding a mask onto dry hair before you shampoo will mean it “can absorb 100 per cent into your hair scales”. This method will fill up the porous scales with the goodness of your pre-wash mask, rather than plain water from the shower.

“Oil is a beautiful treatment for those of you with highly thirsty hair that needs loving to go from complete dullness to high-voltage, megawatt shine,” he tells Body+Soul. “The cooler months are the time to take more care of your hair as it needs that extra volume and shine to protect against the elements.”

In the clinic

Winter, Jamali says, can also be the perfect time for salon procedures such as microneedling, chemical peels, laser treatments and radiofrequency as UV radiation needs to be kept to a minimum following treatment. The same goes for retinols.

“Topical retinoids can make you photosensitive, so I always advise starting them in the winter when we’re less exposed to UV radiation,” she adds.

When it’s more than just dry skin

Dr Yalda Jamali, an expert in facial aesthetics and cosmetic dermatology, explains what to look for and when to seek medical advice for skin issues

It’s common to suffer from dry skin during winter. However, if you feel that your skin is developing rashes, is bumpy and rough in texture, or is excessively itchy or red, seek medical advice. Even if you have dry skin but it’s not settling with increased emollient use, seek advice. Using the wrong products on your skin or excessive itching can lead to long-term implications such as scarring.

Dermatitis is a broad term used to describe a group of itchy inflammatory conditions. It can be pretty confusing as many conditions fall under this term. For example, eczema is a type of dermatitis (atopic dermatitis); however, not all dermatitis cases are eczema. It’s difficult to give broad advice on how to manage different kinds of dermatitis during winter, but if you’re suffering from flare-ups, the simple rule is to avoid triggers, keep the skin well moisturised and seek medical advice.

Psoriasis is a chronic inflammatory skin condition characterised by very well-defined red and scaly plaques. Winter can flare up psoriasis, and my advice is to keep skin well moisturised; this will help the redness and itching. You can’t overdo emollients and ointments. The more you apply, the more hydration is locked into the skin to ease the symptoms.

 

 

 

 

Study suggests Vitamin D and fish oil supplements may help prevent autoimmune disease

Taking daily vitamin D and fish oil supplements may help protect older adults from developing autoimmune disorders such as rheumatoid arthritis, psoriasis, thyroid diseases and polymyalgia rheumatica, an inflammatory disease that causes muscle pain and stiffness in the shoulders and hips, a new study found.

Our Takeaways:

  • The body makes vitamin D when the skin is exposed to sunshine, and consuming fortified food and beverages.
  • People (aged 50+) taking 2,000 IU of vitamin D3 for over five years had a 22% lower rate of confirmed autoimmune diagnoses.
  • Taking both vitamin D and omega-3 fatty acid supplements, versus the placebo, decreased autoimmune disease by about 30%.
  • You should always talk to your doctor first before starting a new regimen.

People age 50 and older taking 2,000 IU (International Units) of vitamin D3 for over five years had a 22% lower relative rate of confirmed autoimmune diagnoses, said study author Dr. Karen Costenbader, a professor of medicine at Harvard Medical School in the division of Rheumatology, Inflammation and Immunity and the director of the lupus program at Brigham and Women’s Hospital in Boston.

That dosage is two to three times the recommended daily dose of vitamin D for adults, which is 600 IU for people up to 69 years old and 800 IU for those age 70 and up, according to the National Institutes of Health.

Once people had been taking vitamin D for at least two years, the prevention rate from autoimmune disorders rose to 39%, according to the study, published Wednesday in the journal BMJ.

The study also found a possible link between taking 1,000 milligrams of omega-3 fatty acid (fish oil) and a reduction in autoimmune disorders, but the association was not statistically significant until possible cases of autoimmune disease — not just confirmed cases — were factored into the analysis.However, the study did find that taking both vitamin D and omega-3 fatty acid supplements, versus the placebo alone, decreased autoimmune disease by about 30%.

Vitamin D toxicity

People should not just run out and start popping vitamin D pills to boost their chances of avoiding autoimmune disease, Costenbader warned, as there are significant consequences to taking too much of the supplement.

Unlike water-soluble vitamins, which the body can easily eliminate, vitamin D is stored in the fat cells of the body and can build up to toxic levels, leading to bone pain and kidney damage.Because the body makes vitamin D when the skin is exposed to sunshine, and milk and other foods like cereals are often fortified with vitamin D, many experts say healthy, younger people are not likely to require vitamin D supplements, especially in amounts over the recommended level of 600 IU/day.

Levels do drop in older age, but “I would say everybody should talk to their doctor first before taking 2000 international units of vitamin D on top of whatever else you’re taking,” Costenbader said. “And there are certain health problems such as kidney stones and hyperparathyroidism (a rise in calcium levels), where you really shouldn’t be taking extra vitamin D.”

The body attacks itself

Costenbader’s study analyzed 25,871 men and women age 50 and older who were participating in VITAL, a randomized, double-blind, placebo-controlled research study designed to see whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (1,000 mg of Omacor fish oil) would reduce the risk for developing cancer, heart disease and stroke in people with no prior history of these illnesses.That trial showed no benefits from the extra supplementation in preventing either cardiovascular disease or cancer. Because prior research has shown both vitamin D and omega-3 fatty acids derived from seafood can have a positive effect on inflammation and immunity in autoimmune disorders, Costenbader decided to use the same trial to investigate whether the supplements might prevent such diseases.

Autoimmune disease occurs when the body’s natural defense system suddenly sees normal cells as invaders and begins destroying those cells by mistake. In rheumatoid arthritis, for example, the immune system attacks the lining of joints, creating inflammation, swelling and pain. With psoriasis, overactive T-cells — which are among the body’s best defenders — cause inflammation that creates raised, scaly patches on the skin.In Type 1 diabetes, the body’s defenders destroy the insulin-producing cells of the pancreas. There’s even some evidence to show that inflammation throughout the body might be part of the progression of Type 2 diabetes. Autoimmune disorders can develop at any stage of life but do appear more among older adults, particularly women, Costenbader said.

More research needed

To date, no large randomized clinical trials (considered the gold standard of research) had investigated whether fish oil and vitamin D could actually prevent the development of autoimmune diseases.

“This is the first direct evidence in older adults that taking vitamin D or omega-3 fatty acids — or a combination — for five years reduces autoimmune disease incidence, with more pronounced effect after two years of supplementation,” Costenbader said.At five years into the research, the study could not tease apart which of the 80 or more autoimmune diseases might benefit most from vitamin D and fish oil supplements, Costenbader said, but research is continuing. The study is now in its seventh year, she said. and more data should be released in the future.
