11Sun Exposure
If you are living in a tropical area, then direct exposure to sunlight can be a trigger of tension headaches. The heat and UV rays would lead to eyestrain and dehydration, which are two common causes of this condition. To reduce the risk, you should avoid exposing to the sun whenever you go out. These include wearing sunglasses, wearing a hat, or using an umbrella. If you are overheated and tired, look for a shaded, cool space and take a rest. [11]
