Testiranje: Mrežaste nosiljke

Nosiljke s mrežastim panelima.

Ljeti se vrlo često poteže pitanje o tome koja je nosiljka najhladnija. Trenutno su izuzetno popularne mrežaste nosiljke, no istovremeno skeptici sumnjičavo dižu obrve jer su takve nosiljke “plastične”.

Jesu li doista hladnije ili je to samo marketinški trik?

Odlučila sam to provjeriti.

[Please scroll down for the English translation]

Odlučila sam testirati Baby Tulu Free-to-Grow (gore lijevo; model Mystic Meadow), Ergoababy Adapt Cool Air Mesh (gore desno; model Pearl Grey), Ergobaby Adapt (dolje lijevo; model Azure Blue) i Baby Tulu Free-to-Grow Coast, model s mrežicom (dolje desno; model Moood).

Za svako smislenije testiranje potrebni su kontrolirani uvjeti i prepoznavanje i uklanjanje svih čimbenika koji bi mogli utjecati na konačne rezultate. Naravno potreban je i precizan mjerni uređaj.

Prvotna ideja mi je bila da šećem jedan sat sa svakom nosiljkom i nakon šetnje fotografiram i uspoređujem znojne mrlje na majicama. 😀

Metoda

Svaku od četiri nosiljke postavila sam s bebačem na sebe i u roku od pola minute napravila prvi snimak toplinskog zračenja, zatim nakon točno 10 minuta napravila drugi snimak da provjerim koliko smo se ugrijali. Bila sam kod kuće, na stabilnih 25 ºC. Između promjene nosiljaka imala sam pauze po 20 minuta. Bebač je na sebi imao platnenu pelenu i pamučnu potkošulju a ja pamučnu majicu s kratkim rukavima. Snimala sam s preciznom FLIR termovizijskom kamerom.

Snimanje

“Obični” Ergobaby Adapt: U intervalu od samo 10 minuta temperatura koja se mogla očitati s površine panela nosiljke skočila je s 25,3 ºC na čak 33,2 ºC! Moram priznati da mi je počelo biti vruće već nakon prve minute.

Nakon pauze od dvadesetak minuta snimanje sam ponovila s mrežastom, ljetnom varijatnom iste nosiljke i dobila vrlo zanimljivi i neočekivani rezultat. U intervalu od 10 minuta nije se gotovo ništa promijenilo! Za nepuni stupanj ºC temperatura je porasla samo iznad pojasa gdje nema 3D mrežice.

Mada na prvi pogled mrežice djeluju plastično Ergova saćasta 3D mrežica doista hladi. Hoće li mekša i tanja Tulina mrežica davati sličan rezultat?

Očekivala sam da će “obična” Tula Free-to-Grow grijati jednako kao Ergo Adapt. Srećom prevarila sam se. Temperature se podigla za tek pola stupnja u gornjem dijelu nosiljke, a u donjem za puni stupanj jer je moj sinčić, očito, napunio pelenu.

Baby Tula FTG (s lijeva na desno): Temperature se podigla tek za pola stupnja u gornjem dijelu nosiljke, a u donjem za puni stupanj ºC jer je moj sinčić, vidljivo, napunio pelenu (lijevo). 🙂

Budući da je obična Tula toliko iznenadila očekivala sam da mrežasta Tula može imati isti ili neznatno bolji rezultat. Iznenadilo me što je temperatura pala (!) za pola stupnja tijekom intervala od 10 minuta, no upravo u trenutku snimanja druge snimke moj je sin počeo dojiti u Tuli Coast.

Tula FTG Coast (s lijeva na desno): Iznenađujuće jest što je temperatura pala za pola stupnja nakon 10 minuta! Na desnoj snimci moj sin upravo taj tren počeo dojiti.

Vidljivo je da je dojenje podiglo temperaturu u samo 5 minuta za 1,5 ºC. Ipak je to fizička aktivnost koja zagrijava nošenče pa tako i nositelja.

Ono što također utječe na dizanje temperature jest i i držanje ruke na panelu, nošenje odjeće od umjetnih materijala, pojačana fizička aktivnost, zagrijavanje nosiljke na suncu, loša cirkulacija zraka…

Ono što također utječe na promjenu temperature jest i držanje ruke na panelu: jasno se vidi otisak dlana (lijevo). Vidljivo je da fizička aktivnost, poput dojenja (desno), podiže temperaturu za 1,5 ºC u samo 5 minuta.

Svi ti rezultati mjerenja temperatura površina panela odražavaju prozračnost i toplinsku vodljivost materijala nosiljke. Dakle u mrežastim nosiljkama je bebi nesumnjivo lakše tijekom vrućeg ljetnog dana, no temperatura između nositelja i nošenčeta ne mijenja se bitno s izborom nosiljke. Tu samo moram napomenuti da ukoliko se beba i krene zagrijavati zbog lošeg izbora materijala nosiljke naše će tijelo, jer je veće, preuzimati bebinu toplinu i tako ju hladiti. Mi ćemo zato steći osjećaj da je u određenoj nosiljci odjednom postalo jako vruće, makar su na nama zapravo samo naramenice i pojas. (Naše tijelo ne može djelotvorno preuzimati bebinu toplinu ako na sebi imamo odjeću od sintetičkih materijala ili ako smo slojevito odjeveni!)

! Ako nošenjem i kožiranjem (eng. skin-to-skin) želite spustiti bebi temperaturu zbog bolesti trebate se skinuti do pasa i bebu skinuti samo u pelenu. Ukoliko temperatura prelazi 39ºC temperaturu skidajte i lijekovima i nazovite dežurnu ambulantu!

Mjerenje temperature između dvaju tijela neposredno nakon nošenja u običnom Ergobaby Adaptu (desno) i Ergobaby Adaptu s mrežastim panelom (lijevo). Temperature su iste.

Iznenadili su me rezultati ovog malog testiranja pa sam testirala i marame i slingove. 

Moram podsjetiti i na nekoliko napomena za zdravo, sigurno i lagodno nošenje beba ljeti.

Testing: Mesh carriers

(Carriers with mesh panels).

In the summer, a common question is which carrier is coolest. Mesh carriers are extremely popular, but at the same time skeptics raise their eyebrows suspiciously, because such carriers are “made of plastics”.

Are they really cooler or is it just a marketing trick?

I decided to check it out.

I decided to test the Baby Tula Free-to-Grow (top left, Mystic Meadow print), Ergoababy Adapt Cool Air Mesh (top right, Pearl Gray), Ergobaby Adapt (bottom left, Azure Blue) and Baby Tula Free- Grow Coast, model with mesh (bottom right, Moood print).

For any meaningful testing, controlled conditions are required and the recognition and removal of all factors that may affect final results are required. Of course, a precise measuring device is also required.

My initial idea was to walk one hour with each carrier and after the walks to photograph and compare sweaty spots on shirts. 😀

Method

I put on each of the four carriers with my baby and made the first thermal camera shot within half a minute, then made another shot after exactly 10 minutes to see how much we heated up. I was at home, at stable 25 ºC.  I had 20 minutes pauses between carriers. The baby was wearing a cloth diaper and a cotton under-shirt, and I had a cotton short-sleeved T-shirt. I shot with a precise FLIR Thermovision Camera.

Recording

“Ordinary” Ergobaby Adapt: At only 10 minutes, the temperature that could be read from the surface of the cargo panel jumped from 25.3 ºC to 33.2 ºC! I have to admit that I started to be hot already after the first minute.

After about twenty minutes of pause, I repeated the recording with the mesh, summer version of the same carrier and got a very interesting and unexpected result. Almost nothing has changed in the 10 minute interval! By not even a whole degree of ºC, the temperature rose only on the part which is just above the belt where there is no 3D mesh.

Though at first glance the mesh looks like plastic, the 3D mesh of Ergobaby carrier indeed has a cooling effet. Will the softer and thicker mesh of Tula’s Coast carriers give similar result?

I was expecting the “ordinary” Tula Free-to-Grow to heat just as Ergo Adapt. Luckily, I have been wrong. The temperature rises for only half a degree in the upper part of the carrier, and in the lower it rose for a full degree because my sun obviously filled the diaper.

Baby Tula FTG (from left to right): The temperature rose only for half a degree in the upper part of the carrier and in the lower by a full degree ºC because my sun, visibly, filled the diaper (left). 🙂

Since I was so suprised by the „ordinary“ Tula, I expected that the mesh Tula could have the same or maybe a slightly better result. I was surprised at the temperature falling (!) for half a degree during the 10 minute interval, but at the time of taking the second shot, my son began breastfeeding in Tula Coast.

Tula FTG Coast (from left to right): Surprisingly, the temperature has fallen for half a degree after 10 minutes! On the right footage, my son just started breastfeeding.

It is noticeable that breastfeeding in just 5 minutes raised the temperature by 1.5 ºC. However, this is a physical activity that warms the carried baby, and the person who is carrying.

What is also affecting the rise of temperature is holding the arm on the panel, wearing artificial materials, the increased physical activity, warming of the carrier in the sun, the poor air ventilation…

What also affects the change of temperature is holding the hand on the panel: the fingerprint is clearly visible (left). It is obvious that physical activity, like breastfeeding (right), raises the temperature by 1.5 ºC in just 5 minutes.

All of these surface temperature measurement results reflect the airiness and thermal conductivity of the carrier material. So, in mesh carriers, the baby is undoubtedly more comfortable on a hot summer day, but the temperature between the person carrying and the baby does not change significantly with the choice of the carrier. I just have to point out here that if your baby starts to warm up because of the poor choice of carrier material, our body just because it is bigger, will take over the baby’s warmth and cool it. We will therefore get the feeling that in a particular carrier, it suddenly became very hot, even though only the straps and waistband are on our body. (Our body can not effectively take the baby’s heat if we have clothes made of synthetic materials, or if we are dressed in layers!)

! If you want to do skin-to-skin to lower your baby’s temperature due to illness, you need to undress from the waist up and baby should have only a diaper on. If the temperature exceeds 39ºC, use medication to lower it and call the on-duty doctor!

I was surprised by the results of this little test, so I also tested the wraps and slings.
