In one sentence, describe what the following article is about: The temperature in the room should be  slightly cooler than what is comfortable for you. A slight drop in temperature induces sleep. This will really help. Do not let yourself get too cold, however, most especially your feet; cold feet can be disruptive to sleep. It is best to put on some socks. You may wake up and remove the socks in the middle of the night, but that is better than letting cold feet keep you awake. It can take several hours for your body temperature to cool down after exercise or exposure to excessive heat, so try to ensure that your body is at normal temperature when you get ready to go to sleep.
Summary: Adjust the temperature.

Dip a cotton ball into a bowl of coconut water. Then, wipe the liquid over your face or any other area you wish to lighten. Leave it on overnight and rinse it off in the morning. You can repeat this daily.  You can also try drinking coconut water to hydrate your skin from the inside out. Coconut water is a great source of essential minerals and is also low in calories. Coconut oil can also have a positive impact on your skin. Apply it two times daily to improve symptoms of eczema and moisturize your skin. Gel made from aloe vera plants is very soothing for the skin. It is also moisturizing and encourages skin rejuvenation. Some think that this enables it to fade dark patches and lighten skin. Break off the leaf of an aloe vera plant (available in plant nurseries) and rub the gel-like sap all over the area you wish to lighten. Repeat this four times a day for at least 15 days in a row.  Aloe vera is good for your skin, so you can use it as often as you'd like with no fear of side effects. You can use commercial aloe gel if it is organic and not made from chemicals. Aloe vera can also help with psoriasis, seborrhea, dandruff, minor burns, skin abrasions, and also radiation-induced skin injuries. Many think that potatoes can lighten skin although there's currently no scientific evidence that proves this. The juice from a raw potato is said to have mild bleaching properties which naturally lighten skin, due to the high quantities of vitamin C it contains. All you need to do is cut a raw potato in half, and rub the exposed flesh on the skin that you wish to lighten. Leave it on your face for 15 minutes and then wash it off. You can use raw potato daily.
Summary: Dip a cotton ball in coconut water. Apply aloe vera gel to your skin. Rub raw potato on your skin.

In one sentence, describe what the following article is about: Warming up before a race helps you give your best performance and prevents injury. Jog for about 10 minutes to warm up your muscles, then do some light stretches. As part of your warm up, do some dynamic stretches, such as high knees, butt kicks, squats, reverse lunges, and alternating side lunges. It’s tempting to sprint out of the starting line so you can secure the lead, but that’s a mistake. Running too fast at the beginning of the race will tire you out sooner, leaving you little energy to finish the race. Instead, pace yourself so you are able to finish the race at a faster pace than the other runners. Don’t let other runners psych you out if they choose to start off fast. Remember, they’re going to burn through all of their energy before the end of the race, so you can always pass them later. At the beginning of the race, you’ll need to manage your energy levels so that you don’t run too fast, which may tire you out too soon. As you progress through the race, you can increase your pace occasionally to pass other runners. However, save your sprint for the end of the race. It’s natural to want to run faster to finish first, but tightening your shoulders and face won't accomplish this goal. In fact, clenching these muscles costs you energy that you could be using for a strong finish. Instead, keep your face and shoulders neutral and relaxed. Check in with yourself when you reach race landmarks and release any tension you're holding in your face or shoulders. Sticking close to your teammates can keep you motivated during the race, so try to run as a pack for most of the race. However, don’t slow down your pace if you’re much faster than your teammates.  Practice sticking together when you go on practice runs. When in doubt, ask your coach for advice about where you should be running in the pack.
Summary:
Warm up about 30 minutes before the race with a light jog and stretching. Start the race at a steady, moderate pace. Keep a quick, even pace rather than alternating between a sprint and a jog. Relax your shoulder and face muscles so you don’t waste energy. Run with your teammates for encouragement.
