U.S researchers have found cooling your hand palms increases the capacity for exercise, the Daily Mail reported.

The team from Stanford University, California, studied the effect in a group of obese women aged 30 to 45 following an exercise program. All were asked to work out with their hands in a bottle of water at different temperatures. For half of the 24 women, the water was at 16C while for the other half the temperature was raised to the normal body temperature level of 37C.

Over a period of three months the women with cooled hands lost almost 3 inches off their waists, lowered their blood pressure and increased their exercise heart rate. Those whose hands were kept at body temperature showed no such improvements.

英國《每日郵報》報道，美國科學家發現，運動同時給手掌降溫，有助于增強鍛煉效果。

美國加州斯坦福大學研究團隊分析了一群30-45歲的肥胖女性參加鍛煉后的效果。所有志愿者被要求手握不同溫度的瓶裝水進行鍛煉。24名女性中，一半的人手握16攝氏度的瓶裝水，另一半握著與體溫相同的37攝氏度的水。

經過3個月時間，手握冷水的女性在鍛煉后，他們的腰圍減少了差不多3英寸（約7.62厘米），血壓降低，心率增強。而手握與體溫相同的水瓶的女性，沒有取得這些效果。
