The Consumer Council has put 20 different types of thermal wear to test, turns out the cheaper options can be more give you more warmth! Before delving into Consumer Council's report, let's take a look at how thermals work.
How heat functions? Our bodies lose heat in a few ways: 1) conduction (heat is transferred from a warmer solid object to a cooler solid object; this is the second law of thermodynamics), 2) convection (heat is transferred from your body to a liquid or gas) and 3) evaporative cooling (the process of a liquid changing state into a gas takes energy, in the form of heat, from its surroundings).
Although thermal wears provide some insulation (conduction and convection), their main job is to fight evaporative cooling. A quick example of evaporative cooling: blow across the back of your hand, lick it, and blow again. The wet feels much cooler🥶. As the water evaporates, it draws energy in the form of heat away from the skin. Thermals draw moisture / sweat away from the skin, minimising evaporative cooling.
The Consumer Council has tested 20 men and women long-sleeved thermal underwear from $99 to $559. Among them, 15 are for daily wear (including Uniqlo, Giordano, Baleno, Martha, Chicken Mark) and 5 are for sports / outdoor activities wear (including The North Face, Columbia). The test focus on: heat retention, water vapour permeability, perspiration and quick-dry performance and durability.

The report stated that the thermal retention value of the test samples varies greatly. Among the 15 daily wear samples, Baleno Thermal Extra has the highest thermal retention value, with an average of 0.23 clo (ranking at #3 among all samples), while Uniqlo Heattech Extra Warm scored 0.17 clo (ranking at #9 among all samples) only.
Among the 5 sportswear samples, the better performances include Wed’ze Fresh Warm Women’s and mont-bell Zeo-line Middle Weight Round Neck Tee Women’s (ranking at top 2 among all samples). Surprisingly, Columbia Omni-heat Midweight Stretch Baselayer and Thermowave have the lowest thermal retention value, measured at only 0.10 clo (ranking at the bottom among all samples). The difference between the test samples of the highest and lowest thermal retention values (from 0.1 clo to 0.32 clo) is more than twofold.

Resilience isn’t a birthright, it’s a skill that can be learnt and practiced with your help.
In today's complex society, the American Psychological Association (APA) has underscored a crucial aspect for our children's well-being - building resilience. Developing resilience in children is more than just throwing them into the deep end of a pool to see whether they can swim; it is about the consistent support you provide them daily. In this blog article, we delve into how you can empower your child to thrive in the face of adversity.Growth mindset: It is a belief that intelligence and abilities can be enhanced through hard work and practice. Children with growth mindset believe that they can learn and improve despite their inborn talent, which encourages perseverance.
Fixed mindset: Contrarily, it is a belief that abilities are fixed. Children with fixed mindset believes that they are either smart or not smart, with not much room of improvement.
Proper praise is important in helping children develop a growth mindset with self-belief. When you praise your child:

Every parent would like to protect their children from hardships in life. Excessive care, however, acts as a barrier, preventing children from learning how to be strong and effectively handle life's problems. In fact, one of the most effective methods for our children to learn is via trial and error. This is unpleasant yet necessary.

It’s the stuff of nightmares: you sit down to tuck into a tasty salad when, suddenly, one of the tomatoes starts to scream as you cut into it.
While the above scenario is a gross exaggeration, biologists from Tel Aviv University have found that plants emit sounds comparable in volume to normal human conversation when they are stressed.
Thankfully, they’re too high pitched for humans to hear but it is likely they can be heard by insects and other mammals, the researchers say.
“Even in a quiet field, there are actually sounds that we don't hear, and those sounds carry information,” said senior author Prof Lilach Hadany, an evolutionary biologist based at Tel Aviv University.
“There are animals that can hear these sounds, so there is the possibility that a lot of acoustic interaction is occurring.
“Plants interact with insects and other animals all the time, and many of these organisms use sound for communication, so it would be very suboptimal for plants to not use sound at all.”

The researchers recorded the sounds of the tomato plants using regular microphones.The researchers placed tomato and tobacco plants in a soundproofed acoustic chamber and then later in a noisy greenhouse environment. In both situations they stressed them first by not watering them for several days and then by cutting off their stems.
After recording the plants, the researchers trained a machine-learning algorithm to analyse the difference in the sounds produced by unstressed plants, thirsty plants, and cut plants.
They found that stressed plants produced around 30 to 50 high-pitched clicks or pops per hour at random intervals, while unstressed produced far fewer.
What’s more, the machine-learning algorithm was able to identify the different types of sounds produced depending on the cause of stress and also which plant they came from.
It’s not yet clear exactly how the plants are producing these sounds, though the researchers suggest that it might be due to the formation and bursting of air bubbles inside the plants.
Similarly, it’s unclear what the purpose of the sounds is. However, it’s likely that other plants and animals are ‘listening in’ to gain some sort of benefit, the researchers say.
“It’s possible that other organisms could have evolved to hear and respond to these sounds,” said Hadany.
“For example, a moth that intends to lay eggs on a plant or an animal that intends to eat a plant could use the sounds to help guide their decision.”
“If other plants have information about stress before it actually occurs, they could prepare.”

FOR IMMEDIATE RELEASE | Press Release
HONG KONG, October 20, 2022 – Mochy, a leading STEM/STEAM education provider in Hong Kong, today teams up with a group of certified sport professionals to pilot a sport-linked STEAM program, spicing up STEM learning for children aged 5-14 through the lens of their favorite sports as real-world application. The program comprises two parts: (1) sport training and (2) sport-related STEAM classroom learning.
In favor of the Education Bureau’s latest renewal of primary curriculum where reinforcing STEAM education is one of the seven major emphases, a recent research by the Legislative Council showed that over 90% of school-aged children did not participate in sufficient physical activity. Mochy wants to help change that by enhancing STEAM to promote sport. The pilot program, namely ‘Stomper’ (with letters of ‘STEM’ and ‘sport’), gives children access to sports that are less accessible at school. For starters, 3 types of sport are available under the STEM Sport Stomper Program: 1) STEAM x Sailing; 2) STEAM x Horse Riding; or 3) STEAM x Golfing.
"As a momtrepreneur, I’m thrilled that my passion for these 3 sports can be share with more kids through Mochy. Mochy is opening doors for children to see the STEM applications behind niche sports that they do not usually associate with science.”
Natalie Lau, Managing Director and STEM Lead at Mochy
"It's an exciting release from our team as we have spent so much effort in putting this program together. We've been on field trips visiting the sites, experiencing the sports, ensuring our curricula and lesson plans are aligned to the standards, like the EBD's Key Learning Area (KLA) Curriculum Guides (General Studies, Science, Technology, Mathematics, etc.) and Physical Education Key Learning Area Curriculum Guide. We are certain that this program can inspire more Hong Kong students to become active learners in STEM."
Arnold Davis, Director at Mochy
Mochy will release Christmas taster camp that includes multiple sports next month. Beyond this pilot program, Mochy will work with Hong Kong school leaders and teachers to further promote STEAM education, by sharing a unique perspective on STEAM subjects that are traditionally seen to be classroom-style in a new light through sports.
Mochy also recently announced The Fullerton Ocean Park Hotel Hong Kong as one of its newly authorized retailers. Visit the hotel’s retail outlets to purchase Mochy’s latest series of STEM toy kits.
