If you want to do cardio exercise, here are some options that don't involve running.
. Hydration is essential: the more hydrated your body is, the more it will be able to adapt to the stress of heat. To estimate how much water your body needs, it is useful to multiply your weight by 0.55, then divide by eight. This is the number of glasses you should drink per day - when working out in the heat, it is best to add two to four extra glasses.Don't wait for the "thirst sign" to appear. It is good to sip water continuously, at least every 15 minutes, to ensure that you stay properly hydrated in hot weather. Better to drink water at room temperature, as it is more easily assimilated in the body. Ice water must be heated before it can be absorbed and beneficial for hydration. But any water is better than no water.
. Since electrolytes are critical to healthy body functioning, make sure they remain properly balanced. How do you know if your electrolytes are low? If you have cramps, dizziness, or low blood pressure, you may have an electrolyte imbalance. You can also pinch your skin and let it go: if it stays lifted, you are probably dehydrated and need sodium and water. To remedy this, a quality electrolyte supplement can be used, which helps the body replenish and repair itself after summer workouts. You can also sprinkle a small amount of Celtic sea salt (less than a quarter of a teaspoon) on your food. Just don't dissolve the salt in water, which could cause nausea.
To rebalance the elements lost during training, it is also useful to drink coconut water.
