It’s getting hotter and hotter outside. Summer is already here! Summer means high temperature, more outdoor activities and all kinds of fruit and vegetables. How can we stay fit in this exciting season? Here are some good ideas:
Eat and drink properly
What is healthy to eat in summer? Fresh and light food. Fish can be a good choice. It can keep your body energetic and help fight against the burning sun. Colorful fruit and vegetables is another good choice. They not only please your eyes, but are full of healthy chemicals(化学物质). Tomatoes can help protect your skin against sunburn. Blueberries are good for your brain and eyes. The more color, the better!
With all those summertime activities you will be thirsty. What to drink? Water. Water has zero calories（卡路里）and is the perfect drink to stop you thirst. Try not to drink too many energy drinks, sports drinks and soda drinks which have lots of sugar and caffeine（咖啡因）in them.
Stay active and cool
Summer is a great season to enjoy outdoor activities and play. It’s also a good time to lose weight. If you are lucky enough to be near a body of water, try water sports like swimming, surfing, water skiing and so on. These sports keep you cool and active at the same time. You’ll have no problem beating the heat and keeping fit as well.
Be careful of the
Summer allows us more chances to get outside, but it also means more possibilities to get burnt by the sunshine. If you are going outside, keep away from the sun when it’s the strongest – usually between 11a.m. and 3p.m.. If you have to stay in the sun for a long time, sunscreen（防晒霜），a big hat and a long-sleeve jacket will be necessary.
