Should you be using a shower head filter?

In the big, wide world of wellness, even the most innocuous of objects may prove to be hazardous to your health. In recent times, it seems even water is not spared from scrutiny—with health buffs speaking up on the negative effects it imparts on an individual's skin and hair. The solution, it seems, arises in the form of a shower head filter. Imagine a built-in sieve designed to reduce the presence and amount of irritating substances, where it is able to weed out nasties in the vein of lead and microplastics. The question, however, remains: is there any accuracy to this accusation?
Funnily enough, the short answer is yes. 'Water does contain disinfectants such as chlorine and chloramine,' elaborates Dr Evelyn Tay, founder and consultant dermatologist at Lumine Dermatology and Laser Clinic. However, that's not to say it's detrimental to your overall wellbeing. 'While chlorine is a potential skin irritant, the role of chlorine on the skin, for example, in atopic eczema is unknown. Studies have not shown an inconsistent association between exposure to chlorine from swimming in childhood with the incidence of atopic eczema. In fact, the effects of chlorine on skin barrier dysfunction is less profound than the hardness of water.' What does hard water actually mean?
'Minerals such as calcium carbonate and magnesium carbonate are found in our water. It also determines the hardness of the water,' states Dr Tay. 'This is often determined by the geography of where the water is obtained from. Removing calcium and magnesium carbonate from water has been shown to reduce the deposition of irritative substances such as Sodium Lauryl Sulfate (SLS) that is left on the skin post shower,' she goes on to add. 'In general, hard water is more alkaline. A higher pH on the skin is associated with an increase in breakdown of natural lipids in the skin, which play an important role in supporting skin barrier function. Hard water has also been shown to thin and weaken the hair shaft, as compared to deionized water. So, does a shower head filter help with this situation?
Not according to Dr Tay. 'A shower head filter mainly removes minerals such as chlorine from water. You see, chlorine is often added to water as part of the disinfection process in water plants. However, a shower head filter does not change the hardness of water; a factor which is accounted for by the concentration of calcium and magnesium in water.' Are there any ways to go about reducing the hardness of water, then?
There are water softener systems and devices out there that do the trick. Homeware brand, 3M, for instance, touts a version which claims to produce brighter clothing, cleaner dishes, as well as less detergent consumption. 'Removing hard minerals like calcium and magnesium will, essentially, better improve the pH of water and reduce irritation risk from shower materials such as SLS,' Dr Tay further explains. 'It may also improve the hair quality in those who have brittle and dry hair.' View this post on Instagram
A post shared by Nécessaire (@necessaire) Does this mean that there are no proven benefits for using a shower head filter?
Not exactly. While a shower head filter won't do as much in improving the complexions of individuals with normal skin types, Dr Tay is quick to point out that it is still beneficial for those with more dry, sensitive skin, particularly if they experience flare-ups after swimming.
'Incorporating a shower head filter into your regime does reduce chlorine concentration in bathing water, and it is proven that chlorine can potentially irritate the skin of those who have atopic dermatitis,' she says. 'It also has a potential drying effect by affecting the ability of the stratum corneum—that is, the outer layer of the skin—to retain water.'

Primary school science lessons Sparkle with refreshed syllabus and new resource kits

Find out what's new on ST website and app. Primary 5 pupil Freya Edenette Moniaga (left) taking a photo of the group work to post on the Singapore Student Learning Space online platform during science class in Yew Tee Primary School on July 22. SINGAPORE - Stepping into Madam Nurhida Sapiie's science lesson at Yew Tee Primary School, it is a flurry of activity. Seated in groups, her pupils are discussing how to complete a task she has given, experimenting with materials from a kit to replicate the human circulatory system. Some are on their feet with iPads, capturing images of their group's handiwork to upload on the Singapore Student Learning Space (SLS) – an online platform. Others are trying to persuade their group mates that there is something amiss with the way they have connected the panels representing the heart, lungs and other parts of the body using the red and blue strings, which represent the blood vessels. The interactive and hands-on nature of Madam Nurhida's lesson is made possible with a kit created by the Ministry of Education (MOE), the National Institute of Education, and Science Centre Singapore. Sparkle – short for Science Pack Activity Resource Kits for Learning – was introduced in 2023 starting with the Primary 3 cohort, along with the science curriculum refresh. The final kits for Primary 6s will be adopted in 2026. Top stories Swipe. Select. Stay informed.

'I remember just sitting and looking at my teacher at the front. There was not much opportunity for us to conduct experiments until we entered secondary school.' Designed to complement textbooks, activity books, and SLS materials, Sparkle comprises 19 kits covering 18 topics from Primary 3 to 6, such as light, heat and living things. Each school receives 23 sets of each kit. Each kit is stocked differently. For example, the 'living things' kit contains a game placemat and playing cards for pupils to learn about the characteristics of plants, animals, bacteria and fungi. The kit on light comprises a collapsable box, LED bulbs and batteries for pupils to experiment with shadow formation and the properties of light. At Yew Tee Primary, teachers coordinate lesson schedules across classes to ensure all pupils have access to the kits as they begin each new topic. In the past, she said she would need to spend time planning and thinking about extra activities and materials she could use – apart from the textbook and activity book – to make lessons more engaging. One of her challenges was ensuring materials like online videos were aligned with the MOE science syllabus. Madam Nurhida said the extra resources help students better understand scientific concepts. With these set of resources, teachers can focus on selecting what they need from the Sparkle kits, instead of creating or looking for materials from scratch, she said.

ST PHOTO: KEVIN LIM She added that the resources are designed in a way to cater to pupils of different learning abilities. Those who grasp concepts faster can be given more demanding tasks to do while others who need more time can do something easier. For example, during her lesson, some groups had the option to use four panels and both the red and blue strings to construct the model of the ciculatory system, while others opted to use three panels and just one string to make it easier. Primary 5 pupil Wong Zi Yuan, 11, said the Sparkle kits make lessons more fun and engaging. Madam Nurhida Sapiie said the extra resources help students better understand scientific concepts. ST PHOTO: KEVIN LIM 'Instead of just paperwork, which I think is kind of boring, we get to do hands-on activities and work together with our classmates,' he said, adding that exchanging ideas with his peers help them find the best solutions. Lessons with hands-on projects help him with remembering concepts and information during examinations, he said. Said Zi Yuan: 'If I come across similar questions, then I'm able to picture it in my mind, because I've seen it once before. So it will help me remember more stuff.'

Livingstone Health back in the black, logs H2 profit of S$0.4 million from streamlining efforts, higher revenue

[SINGAPORE] Livingstone Health Holdings Limited booked a net profit of S$0.4 million for the second half-year ended Mar 31, a reversal of the net loss of S$2.9 million in the year-ago period. The turnaround came mainly from its ongoing streamlining efforts, the Singapore-based medical group said in a regulatory filing on Thursday (May 29). The mainboard-listed company operates 20 clinics in Singapore; it has 22 medical specialists and practitioners, a health-screening centre, two medical aesthetics clinics and a podiatry clinic. It also provides healthcare consultancy services within the region. Earnings per share likewise rose to 0.07 Singapore cents, from a loss per share of 0.66 cents in the year-ago period. H2 revenue rose 17.9 per cent to S$14.2 million, from S$12 million the year before. This was mainly attributable to higher revenue contribution from all business segments. The latest results bring Livingstone's full-year net profit to S$0.6 million, swinging back into the black from a full-year net loss of S$2.9 million the year before. Full-year revenue grew 9 per cent to S$27.6 million. BT in your inbox Start and end each day with the latest news stories and analyses delivered straight to your inbox. Sign Up Sign Up Commenting on the results, the group's executive director and chief executive officer, Wilson Tay, said the retention of its medical professionals helped sustain its revenue. To improve efficiency, Livingstone streamlined its operations and optimised cost structures. This included reducing its spending on employee benefits by S$0.2 million to S$15 million, and other operating expenses by S$0.1 million to S$4.9 million. The company also stepped up on its efforts to collect on accounts receivable, resulting in a net bad-debt recovery of S$43,000 in FY2025, also a turnaround from the net impairment loss of S$0.6 million in FY2024. Livingstone recorded other operating income of S$0.8 million, mainly from government grants, rental income and interest income. It also registered a net other gain of around S$58,000 from the consolidation of its joint venture, Atlas Podiatry. Dr Tay noted that the group completed its acquisition of the remaining 49 per cent stake in Phoenix Medical Group (PMG) in August 2024. He added that an internal reorganisation of PMG's primary-care operations also built a dedicated team to improve clinic efficiency, including at its new outlets. He said these were 'accretive investments' that aligned with Livingstone's strategy of expanding its primary-healthcare segment through PMG's established networks. Livingstone plans to strengthen its operations by reaching more patients and enhancing cross-referral networks among its medical services. It is also exploring new revenue sources, including marketing and business-development initiatives to attract more international patients to its Specialist Healthcare segment. As at 11 am on Friday, shares of Livingstone Health were down S$0.002 or 8.7 per cent at S$0.021.
