Exercise/sport
If you were active before pregnancy, it is a good idea to stay that way during pregnancy
too. By keeping fit, you will cope better when the baby is born. But remember that the
aim of exercise in pregnancy is to maintain fitness, not improve athletic performance.
If you haven’t been physically active before pregnancy, now is the time to begin a gentle
exercise program suitable for pregnancy. Ask about this when you attend your childbirth
education course (see Chapter 8, Antenatal Exercises).
If you normally play sport, ask your doctor or midwife if you can continue during
pregnancy. Some activities are safe, as long as you take things easy, stop when you feel
tired and don’t overheat.
However, some activities can pose problems - obvious ones are contact sports which can
cause injury. Others include scuba diving (excess oxygen or carbon dioxide can harm the
baby) and water skiing (water surging into the uterus may cause miscarriage).
If you go to exercise classes, check with your doctor or midwife that it is okay to
continue. Remember to tell your instructor that you are pregnant. You will need to slow
down your pace.
Alternatively, you could look for a class that caters for pregnant women.
One of the effects of pregnancy is that your body’s ligaments become softer - this makes
them more vulnerable to injury. High-impact exercises and repetitive bouncing, jumping
or jarring movements are more likely to cause problems, but you can risk injuries with
some low-impact exercises too.
After the 20th week, it is important not to do exercises lying flat on your back - this can
reduce the blood flow to the growing baby. If you are concerned about any of the exercises
you do, ask a physiotherapist for advice.
Overheating
It is important to avoid becoming too hot, especially in the first three months of
pregnancy, or if you are planning a pregnancy. If you do, your body’s core temperature
can rise and this may harm the baby (see Chapter 1, Keep Cool).
Playing a sport, running or doing a vigorous exercise class on a hot day can be enough to
raise your core temperature. Staying as cool as possible, not exercising too strenuously
and drinking fluids during and after exercise will help to keep your core temperature
down.
Women with certain medical conditions who are likely to have complications during
pregnancy or who are having twins should avoid exercise. Check with your doctor or
midwife.
