Gearing up for an Outdoor Winter Activity
Winter sports and activities can be a lot of fun. It's a
splendid time of the year when it seems like you are enveloped
by the pristine whiteness of the snow. But it is also a
hazardous time of the year for the outdoor adventurer. One has
to keep warm to keep safe and enjoy this time of the year. The
essence of staying warm in the winter is having the proper
clothing layers and knowing how to use them effectively. Here
are some tips.
Dress in layers
Our body loses heat through conduction, convection, evaporation,
radiation and perspiration. As activity levels increase so does
the heat produced in our body and vice-versa. Thus it becomes
important to insulate our body to keep warm and this is done by
the layering technique. When we wear our clothes in layers, we
ensure that there is enough dead air space, (defined as any
enclosed unit of air that is small enough so that natural
convection currents would not arise in it), which can be shed
off layer by layer, to balance the heat levels of your body. So
while you need to dress warmly, you also need to dress in layers
so that you can be ready for temperature changes of the body.
As the old adage goes, if your toes are cold, put on a hat ..
You can lose up to 70% of your body heat from your head, so hats
are essential for any winter activity. You may even need to get
a face mask if you are at risk from high wind conditions and
susceptible to frost bite of the face.
Put your hands in gloves
Mittens are considered warmer than gloves as the fingers can
keep each other warm rather than being isolated in the glove's
fingers. You can apply the layering principle here as well by
using an inner mitten and an outer shell. However, gloves are
essential too, especially the water proof variety, as various
winter activities require a certain amount of dexterity, which
winter mittens
can't provide.
Layer your feet with socks
Wear multiple layers of socks starting with thin polypropylene
liner socks, which will keep the feet dry, followed by one or
two layers of wool or wool/nylon blend socks. The outer layer of
socks needs to be big enough to accommodate the inner layers.
Wear a Waterproof outer layer
While it would be ideal to have a waterproof outer layer, it is
essential to make your outer most layer of clothing windproof
and at least water resistant. Also the garment needs to be able
to be ventilated. So sometimes it's a trade off between how much
'waterproofness' is desired and the ability to ventilate.
Ventilation is important because a completely waterproof item
will keep the water that is moving through your other layers
trapped, adding to weight and causing some heat loss.
